THE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT

BACKGROUND OF THE INVENTION
This section is intended to introduce various aspects of the art, which may be associated with exemplary embodiments of the present disclosure. This discussion is believed to assist in providing a framework to facilitate a better understanding of particular aspects of the present disclosure. Accordingly, it should be understood that this section should be read in this light, and not necessarily as admissions of prior art.
Field of the Invention
The present invention relates to cosmetic systems. More specifically, the invention relates to a cosmetic system that may be used to obscure dermatological defects. The invention also relates to methods for disguising dermatological blemishes.
Discussion of Technology
Some persons carry a skin defect that may cause embarrassment. The defect may be the result of a surgical procedure such as a tracheostomy, leaving permanent scarring in the neck. Alternatively, the defect may be a result of trauma such as an automobile accident, a fall, or an assault. Alternatively, the defect may be significant skin blemishes due to acne scarring. In any of these instances, the person may be self-conscious about their appearance and seek to disguise or camouflage the skin defect.
Cosmetic materials are well-known as a means of enhancing or otherwise altering a person's appearance. Cosmetics are used to cover inconsistent skin pigmentation and wrinkles. However, standard cosmetics are not always suitable where the skin defect is profound.
For significant physiological defects, prostheses such as maxillofacial prosthetics are known. Such prosthetics may be of particular use for patients who have undergone the removal of a highly visible portion of their anatomy such as an ear, the nose, or an ocular orbit due to cancer. U.S. Pat. No. 4,623,593 discusses such a prosthetic. The '593 patent is entitled “Self-Adhesive Polymer Composition for Use as Prosthetic Appliance,” and discloses the use of polymeric materials for maxillofacial prosthetics.
The '593 patent notes that “[a] number of different types of polymeric materials have been utilized as base materials for prostheses.” The patent mentions “silicone rubbers and polyurethanes.” The '593 patent describes a molding process for the prosthetic that results in a tacky characteristic. The patent specifically states: “We have found that an integral surface layer having pressure-sensitive adhesive properties may be formed on an otherwise fully cured polymeric body. This may be accomplished by applying a sufficient amount of a cross-linking inhibition agent to selected surfaces of a mold cavity prior to packing the cavity with uncured monomeric, prepolymeric, or unvulcanized polymeric material. The mold is then closed and the material cured. The cross-linking inhibition agent acts on the surface or surfaces of the polymer to prevent complete cross-linking thereof. The body of the polymer is otherwise completely cured and has the same properties as would be expected.” The end product is offered in a cured state.
Maxillofacial prosthetics may be too expensive or too cumbersome in the case of “mere” skin defects. U.S. Pat. No. 5,147,401 and U.S. Pat. No. 6,383,220 are each entitled “Artificial Skin.” These patents teach skin coverings to aid in the protection and healing of flesh wounds. There is no discussion concerning the temporary covering of skin defects or scars, nor is there a teaching of applying an uncured or uncatalyzed silicone-based material to the patient's skin.
Therefore, a need exists for a cosmetic system that is able to disguise a profound skin defect such as surgical scarring or acne pitting that cannot be effectively covered by traditional makeup. Further, a need exists for a method of disguising dermatological blemishes using a cosmetic system that may be purchased by a consumer as a kit and used to create a translucent, realistic artificial skin in a dermatological area.
SUMMARY OF THE INVENTION
The present invention provides methods for disguising dermatological blemishes on a human user. The methods employ a cosmetic system in the form of a kit that is provided or sold to a user as a box or other package.
The method first includes opening the package. In one aspect, the package includes a first silicone container. Residing within the first silicone container is a viscous silicone material. The kit also includes a catalyst container. Residing within the catalyst container is a catalyst, such as a platinum metal catalyst. The catalyst is fabricated to react with the viscous silicone material such that when mixed with the silicone material and spread, the silicone material cures as a translucent elastic layer bonded to the human skin.
To facilitate bonding, the kit may include a skin prepping solution. The skin prepping solution may be, for example, a cleansing agent such as ethyl acetate. More preferably, the skin prepping solution may be a primer such as a silicone material dispersed in an alcohol. In this instance, the skin prepping solution may be rolled or brushed onto a user's skin.
The package also includes at least one skin texturing pad. The skin texturing pad is fabricated with dimples for creating texture to the translucent elastic layer while the silicone material is curing. In this way, dimples are formed in the elastic layer that reflect a porous pattern of a dermatological area of interest on the human user.
The elastic layer, when cured, is tinted. To enable this, the silicone material includes a pigment dispersed within the silicone material. Alternatively or in addition, the catalyst includes a pigment. The pigment is designed to tint the resulting elastic layer according to a selected skin tone.
In one aspect of the kit, a flocking agent is provided. The flocking agent is pre-mixed into the silicone material, the catalyst, or both. The flocking agent is designed to provide texture so that the elastic layer visually blends in with the user's skin. The flocking agent may comprise natural hair, natural fibers, or synthetic fibers.
The silicone container and the catalyst container may be separate jars from which a user can scoop a needed amount of material for mixing and curing. Alternatively, the catalyst and the base may reside in separate pump containers. More preferably, the silicone container and the catalyst container are cartridges or volumes that are held together in a dispenser. The dispenser may be either a dispensing gun or a syringe. In either instance, the double-barrel dispenser is used to extrude the silicone material and the catalyst together onto the user's skin from the silicone container and the catalyst container.
The cosmetic kit may further comprise a plurality of disposable mixing tips. Each tip is configured to removably attach to a distal end of the dispenser such that upon dispensing of the silicone material and the catalyst, a silicone mixture is formed that will quickly cure. Preferably, the silicone material and the catalyst are dispensed at substantially a 1:1 ratio by volume. As the viscous components are extruded through the tip of the volumes, the silicone material and the catalyst are mixed for curing on the user's skin.
The method also includes mixing a portion of the silicone material and a portion of the catalyst from the kit to form a silicone mixture. Preferably, the silicone material and the catalyst are extruded from a double-barrel syringe having a mixing tip. The method then includes applying the silicone mixture on a dermatological area of interest.
The method further includes applying one of the at least one skin texturing pad to the silicone mixture. This is done before the silicone mixture cures. In this way, texture is created along the silicone material. Thereafter, the method comprises allowing the silicone material to cure on a skin surface of the human user. The silicone mixture becomes removably bonded to the user's skin as it cures.
Other kits may be used with the method. For example, in an alternate embodiment the second cosmetic kit comprises a first syringe having a first and a second volume within a package. A viscous silicone material resides within the first volume. The silicone material is tinted to match a selected skin tone. Preferably, the silicone material is tinted by a pigment dispersed within the silicone material. The pigment may be a pigmented silicone oil, a pigmented cosmetic cream, or a pigmented powder.
The silicone material further has a flocking agent dispersed therein to provide texture. In this way the silicone material visually blends in to the user's skin upon curing.
A catalyst resides within the second volume. The catalyst is fabricated to react with the viscous silicone material such that when mixed with the silicone material, the silicone material cures as a translucent elastic layer capable of bonding onto human skin. Preferably, the dispenser is a double-barrel syringe that allows the silicone material and the catalyst to be extruded simultaneously in about a 1:1 volume ratio.
The alternate cosmetic kit also comprises a skin prepping solution. The kit may further have at least one skin texturing pad. The skin texturing pad is fabricated with dimples for creating texture to the translucent elastic layer while the silicone material is curing. In this way, dimples are formed in the elastic layer that reflect a porous pattern of a dermatological area of interest on the human user.
The alternate cosmetic kit also includes a box or other packaging. The box may contain at least the first syringe, the skin prepping solution, and the skin texturing pad. A plurality of disposable mixing tips may also be provided in the box. Each tip is configured to attach to a distal end of the syringe such that upon dispensing of the silicone material and catalyst, the silicone material and the catalyst pass through the mixing tip for mixing.
The alternate cosmetic kit may further comprise a second syringe and a third syringe. Each of the first, second, and third syringes has a first volume that contains a silicone material. The silicone material is tinted by a pigment, wherein the silicone material in each of the first, second and third syringes is tinted to match a different selected skin tone. In this way, a purchaser of the kit may readily choose a syringe that most closely matches his or her skin tone.

Alternatively, the silicone material may be, for example, of the crosslinked organosiloxane type. The silicone material may be in the form of an emulsion. Suitable emulsions include but are not limited to water-in-silicone emulsions, oil-in-water emulsions, and silicone-in-water emulsions.
The term “catalyst” refers to a material which, when combined with silicone, cures to form a substantially solid material. A non-limiting example is a platinum-type catalyst.
The term “dispenser” refers to any apparatus that dispenses a silicone material and a catalyst in such a manner that the silicone material and the catalyst are available for mixing and curing. A non-limiting example is a double-barrel syringe that allows the materials to be simultaneously extruded and mixed.
Description of Selected Specific Embodiments
The present invention provides methods for disguising dermatological defects and blemishes. The methods employ a unique cosmetic system in the form of a kit that is provided or sold to a user in a box or package. The cosmetic system is a silicone-based system that can be used to temporarily fill acne blemishes. Alternatively, the cosmetic system may be used to disguise more significant scars that may arise from surgeries, diseases or traumatic accidents.
The cosmetic system first comprises a silicone material. In one embodiment, the silicone material is fabricated from a dimethyl silicone such as polydimethylsiloxane. Such silicones are available, for example, from NuSil Technology of Carpinteria, Calif. However, the cosmetic systems herein are not limited to any particular type or source of silicone material, so long as the silicone material may be catalyzed at room temperature. Preferably, the silicone material has the viscosity of a gel or soft solid at room temperature conditions, prior to catalysis.
It is necessary for the silicone material to be cured, such as through a process of catalysis. Therefore, the cosmetic system next includes a catalyst. The cosmetic systems herein are not any limited to any particular type or source of catalyst. However, it is preferred that a non-toxic reaction occur during catalysis. A preferred catalyst is a platinum metal catalyst.
One particularly desired combination of silicone material and catalyst is the NuSil™ MED2-4220. MED2-4220 comes in Parts A and B, with Part A being the catalyst, and Part B being the silicone material. For catalysis, Parts A and B of MED2-4220 may be degassed, and mixed at 50%/50% proportions. A 50 centistoke oil may be added to Part A, Part B, or both, prior to mixing. The oil serves as a diluent to facilitate extrusion through a dispenser (described below). Stated another way, the diluent reduces the viscosity of the silicone material. At higher percentages, the diluent also softens the final cured product, making it more pliable. This is of benefit for larger patch applications on a user's skin.
MED2-4220 provides an advantageous combination of silicone material and catalyst. Parts A and B each provide high viscosity and temperature tolerance before catalysis, and good optical clarity upon mixing and curing. It should be added that a small amount of platinum accelerator may optionally be added to the catalyst to accelerate the curing or vulcanization process. Accelerators may reduce the life of a resulting silicone product. However, the present application is designed to be temporary, i.e., lasting less than about 72 hours before it is removed.
The MED2-4220 NuSil™ product offers a fast-curing, medical grade, silicone elastomer. The elastomer cures with a translucent appearance in just about 5 minutes, and offers a tensile strength that is generally about 550 psi. Other Nusil™ products may be considered. For example, the MED-6820 combination of silicone material and catalyst may be advantageous in some contexts. MED-6820 offers a higher tensile strength, but may cure in too clear of a finish which may not be desired when covering dermatological blemishes.
As noted, the silicone material and the catalyst are mixed to provide a silicone mixture. In one aspect, the silicone mixture is custom-blended. This means that the mixture includes a cosmetic pigment that has been added to match a selected skin tone. Using pigments, various tints or shades of silicone mixture may be provided in different containers so that customers may select an intrinsically colored product that most closely matches their own skin tone.
The pigment is preferably a cosmetic pigment that is fabricated from a pressed cream. Examples of a suitable pressed cream include cream-based makeup. The cream may be water-based, silicone-based or petroleum-based.
As an alternative, the pigment may be a powder such as a cosmetic make-up powder. Alternatively, the pigment may be a silicone pigment. Various tones or colors of silicone pigment are available from NuSil Technology. Also, Eager Plastics, Inc. of Chicago, Ill. provides opaque silicone pigments having no/low odor and toxicity.
The pigment may be pre-mixed with the silicone material. Alternatively, the pigment may be pre-mixed with the catalyst, though preferably the pigment would not be a silicone-based cream in this instance. Alternatively still, the pigment may be supplied as a separate component and mixed with both the silicone material and the catalyst at the time the mixture is formed by a user. In this latter instance, the pigment will need a carrier material such as a low-viscosity silicone compound.
The cosmetic system optionally also includes a flocking agent. The flocking agent is used to provide depth and texture to the cosmetic mixture. The flocking agent may also provide color. Preferably, the flocking agent is pre-mixed with the silicone material. However, it may alternatively be pre-mixed with the catalyst. Alternatively still, the flocking agent may be supplied as a separate component with a pigment, and then mixed with both the silicone material and the catalyst at the time the mixture is formed by a user.
The flocking agent is preferably in the form of rayon fibers that are cut in very short sections, such as 5 to 25 mm. However, any material that is capable of providing texture to the silicone material may be used. Non-limiting examples include human hair, natural fibers, e.g., cotton and pulp, or synthetic fibers. The flocking agent may be of any color. However, in one aspect the flocking agent has a brown or black color so that flocking agent may be added to the silicone material to selectively darken the final mixture.
A very small amount of a thickening agent may be included with the silicone material. This is for the purpose of suspending the rayon fibers or other flocking agent in the viscous material. An example of a suitable thickening agent is the so-called Cabosil thickener. The term “cabosil” is an abbreviation for colloidal silica. Cabisol is a silica-based thickener that increases the viscosity of silicone. The silica-based thickener is desirable in the present application as it has been found that it will not change colors during the catalysis process. Cabosil is available from various sources, but is believed to be manufactured by Dow Chemical Company of Midland, Mich. and/or Cabot Corporation of Boston, Mass.
Another example of a thickening agent is a thixotropic agent. A thixatropic agent maintains a gel in a substantially solid or gelatinous phase during a sedentary state, but permits a reduction in viscosity when shaken or otherwise disturbed. The thixatropic agent also assists in suspending the rayon (or other) fibers. This prevents a condition known as “slumping.”
In order to dispense the silicone material onto a patient's skin, a dispenser is preferably employed. Thus, in one embodiment the cosmetic system includes a syringe. FIG. 1 is a perspective view of a syringe 100 for dispensing a silicone material and a catalyst together. The syringe 100 has a first volume 112 for containing a silicone material. The syringe 100 also has a second volume 114 for containing a catalyst. Thus, in the embodiment of FIG. 1 , the syringe 100 is a double-barrel syringe.
Each volume 112 , 114 terminates at a tip 113 . The viscous silicone material and catalyst are extruded through respective tips 113 . The materials may be extruded directly onto a human user's skin, or may be placed in a dish for manual mixing. Opposite the tips 113 is a base plate 116 .
Each volume 112 , 114 receives a plunger 118 . A push-end 118 is provided at a proximal end of the plungers 118 . In this way the user may push on the plungers 118 to simultaneously extrude the silicone material and the catalyst.
An optional mixing tip 150 may also be used as part of the syringe 100 . The mixing tip 150 is detachable, and serves to mix the silicone material and the catalyst as the components are extruded from their respective volumes 112 , 114 . In the view of FIG. 1 , the mixing tip 150 is exploded away from the syringe 100 for illustrative purposes.
The dispenser may alternatively be a dispensing gun. The dispensing gun is preferably a dual chamber applicator that receives two cartridges. A first cartridge holds the silicone material, while a second cartridge holds the catalyst.
In one aspect, the dispensing gun is the dispenser that was the subject of U.S. Pat. No. 5,333,760, entitled “Dispensing and Mixing Apparatus.” The assignee of the '760 patent is listed as Coltene/Whaledent, Inc. of Mahwah, N.J. This patent is incorporated herein to the extent it is consistent with the present disclosure.
FIG. 2 provides a schematic view of another dispensing gun 200 as may be used in the cosmetic system herein. The illustrative gun 200 is a dual cartridge dispensing apparatus for dispensing and mixing the viscous components of the cosmetic system, to wit, the silicone material and the catalyst. The silicone material and the catalyst are held in respective cartridges. The cartridges are seen in phantom at 232 and 234 , indicating that they are not part of the dispensing gun 200 itself. The first cartridge 232 is pre-packed with the silicone material, while the second cartridge 234 is pre-packed with the catalyst. Preferably, the silicone material in the first cartridge 232 is pre-mixed with the pigment, the flocking agent, and a thixatropic (or other thickening) agent.
As seen in FIG. 2 , the dispensing gun 200 includes a body 210 . The body 1210 supports other components of the dispensing gun 200 as described below. Operatively connected to the body 210 is a ratcheting system. The ratcheting system comprises a handle 220 and an actuating trigger 222 . By repetitively squeezing the trigger 222 , the silicone material and the catalyst are urged under pressure from the respective cartridges 232 , 234 simultaneously.
The dispensing gun 200 also includes a chamber 230 . The chamber 230 may be an elongated receptacle for receiving the cartridges, as in the dispensing apparatus of the '760 patent. In the '760 patent, the chamber is separated into two compartments, with each of the compartments receiving a separate cartridge in which the viscous components are stored. However, in the arrangement of FIG. 2 the chamber defines a slot. The slot 230 receives a plate (seen at 16 in FIG. 4 ) that in turn connects to and supports the two cartridges 232 , 234 .
The dispensing gun 200 also includes a pair of pistons 226 , 228 . The pistons 226 , 228 act against the viscous materials in the cartridges 232 , 234 in order to urge the materials from the cartridges 232 , 234 . Each of the pistons 226 , 228 is carried at the end of a respective rail 223 . The rails 223 travel forward through the body 210 and the chamber 230 of the dispensing gun 200 as the actuating trigger 222 is repetitively squeezed. The rails 223 include a toothed edge 225 which advances the pistons 226 , 228 as part of the ratcheting system.
It is understood that the ratcheting system further includes gears, teeth or other advancing mechanism within the body. This commonly known feature is not illustrated or further described herein.
The dispensing gun 200 next includes a mixing tip 250 . The use of a mixing tip, or “static mixer,” is known in the art of mixing extruded components. The mixing tip may be of various types such as those described in U.S. Pat. Nos. 4,538,920; 3,923,288; 3,635,444, or others. In one arrangement, the mixing tip is integral to the chamber 230 . This type of arrangement is shown in the dispensing apparatus of the '760 patent.
In the illustrative arrangement of FIG. 2 , the mixing tip 250 defines a separate member. This means that the mixing tip 250 may be disconnected from other components for cleaning or even replacement. The mixing tip 250 includes a wall 254 and a central bore 255 (seen in FIG. 3 ) through which the viscous silicone material and the catalyst flow from the cartridges 232 , 234 , respectively, when the ratcheting system is actuated.
The mixing tip 250 of FIG. 2 includes a flanged proximate end 258 . The flanged proximate end 258 is configured to snap into a bracket formed on the cartridges 232 , 234 . (The bracket is seen at 22 in FIG. 4 at the distal end 12 of the cartridges 232 , 234 .) In this way, a sealed connection between the cartridges 232 , 234 and the mixing tip 250 may be acquired, while at the same time the mixing tip be removable and disposable.
The dispensing gun 200 will be provided to the user along with at least one cartridge 232 containing a tinted silicone material, and at least one cartridge 234 containing a catalyst. In addition, a plurality of disposable mixing tips 250 is preferably provided with the dispensing gun 100 .
FIG. 3 is a top, cross-sectional view of a portion of the dispensing gun 200 of FIG. 2 . In this view, certain features of the dispensing gun 200 are more clearly seen. A portion of material in the cartridges 232 , 234 has been extruded so that the rails 225 are visible. As noted, the rails advance through the body 210 in response to ratcheting of the trigger 222 . Also visible is the slot 230 . Again, the slot 230 receives the plate 16 that supports the cartridges 232 , 234 .
Also seen in FIG. 3 is a mixing tip 250 . The mixing tip 250 is shown at the end of the rails 225 . However, it is understood that the mixing tip 250 is actually connected to the distal ends 12 of the respective cartridges 232 , 234 , as described above.
The mixing tip 250 defines a central bore 255 . The central bore 255 receives the viscous silicone material and the catalyst as they are urged from the dispensing gun 200 and the respective cartridges 232 , 234 . The viscous components are mixed as they travel through the bore 255 . Preferably, the central bore 255 has a plurality of stationary mixing vanes 244 internal of the bore 255 . The mixing vanes 244 can be of various shapes so long as they assist the components in being mixed together as they are forced through the bore 255 .
Openings 252 are provided at the proximate flanged end 258 of the mixing tip 250 . The openings 252 receive the viscous components as they are urged from the cartridges 232 , 234 . The components travel through the bore 255 and exit the mixing tip through a distal end 246 .
FIG. 4 is a perspective view of two cartridges 232 , 234 for holding the viscous components, to wit, the silicone-based material and the catalyst. The two cartridges 232 , 234 are sized to be received within the chamber 230 of the dispensing gun 200 . In the illustrative arrangement, the plate 16 slides into the slot that defines the chamber 230 . The cartridges 232 , 234 are preferably substantially circular in cross-section. Preferably, the cartridges 232 , 234 are fabricated from a transparent or translucent plastic material.
Each cartridge 232 , 234 defines an inner bore 15 or volume for receiving a viscous material. The diameter of the inner bore 15 may range from about 1.0 to about 3.0 cm, although this range is simply illustrative. The cartridges 232 , 234 may have different inner diameters, or equivalent inner diameters. Each cartridge 232 , 234 has a posterior end 10 and an anterior end 12 . The posterior ends 10 each receive a sealed cap 11 . The sealed cap 11 is movable along the inner bore 15 of the cartridges 232 , 234 in response to force applied by the pistons 226 , 228 . The anterior ends 12 of the cartridges 232 , 234 include an outlet 18 . The outlets 18 in the cartridges 232 , 234 are aligned with the openings 252 in the mixing tip 250 .
The cartridges 232 , 234 shown in FIG. 4 are integral. In this respect, the posterior ends 14 of the cartridges 232 , 234 are connected to a plate 16 . The plate 16 , in turn, slides into the chamber 230 in the dispensing gun 200 . The anterior ends 12 of the cartridges 232 , 234 form a bracket 22 . The bracket 22 , in turn, receives a cap 20 . The cap 20 slides into the opposing halves making up the bracket 22 in order to provide a seal to the openings 18 before the cartridges 232 , 234 are loaded into the dispensing gun 200 . The cap 20 includes a small handle 24 for gripping the cap 20 .
When the dispensing gun 200 is ready for use, the cap 20 is removed from the cartridges 232 , 234 . The cartridges 232 , 234 are then inserted into the slot defining the chamber 230 . The mixing tip 250 is then slid into the bracket 22 . In one aspect, the mixing tip 250 is rotated in order to lock the mixing tip 250 onto the bracket 22 .
It is noted that the two cartridges 232 , 234 may be separate items, that is, not permanently connected. It is also noted that more than two cartridges might be used in dispensing viscous fluids in the cosmetic system. For instance, a first cartridge might hold a silicone material, a second cartridge might hold a catalyst, and a third cartridge might hold a pigment in a carrier material. In this instance, the third cartridge would have a much smaller bore than the first and second cartridges. The flocking material may be included in any of the three cartridges or even all three.
The cartridges 232 , 234 each contain a viscous component. The viscous components are extruded from the cartridges 232 , 234 and through the openings 18 in response to action of the dispensing trigger 222 . More specifically, the trigger 222 urges the pistons 226 , 228 , which in turn act against the sealed caps 11 at the posterior ends 10 of the cartridges 232 , 234 . Ultimately, the viscous components are extruded into the mixing tip 250 and out the distal end 246 . In this way, the silicone material and the catalyst are mixed to form a silicone mixture so that a cosmetic material may be cured on the skin surface of a user. In one aspect, the cured silicone mixture has a durometer of about 5 to 25.
The dispensing guns 100 , 200 shown and described in connection with FIGS. 1 , 2 and 3 are merely illustrative. It is understood that any dispensing apparatus capable of moving the viscous components of the cosmetic system from a dispenser may be employed. Preferably, the silicone material and catalyst are mixed for application onto skin.
The cosmetic system may also comprise a skin prepping solution. In one embodiment, the skin prepping solution is designed to remove oil and dirt from a dermatological area of interest. For example, the skin prepping solution may be a solvent such as ethyl acetate. The skin prepping solution is applied to the skin before the silicone material is dispensed.
In another aspect, the skin prepping solution is a primer. An example of a primer is a silicone material dispersed in an alcohol. In this instance, the skin prepping solution may be rolled, brushed, or sprayed onto a user's skin. The user may wait 15 to 30 seconds after application. The alcohol flashes off, and a silicone film remains.
An example of a suitable primer is the CV-1161 from NuSil Silicone Technology of Carpentaria, Calif. CV-1161 is a translucent, pressure-sensitive, silicone adhesive. The applicant recommends that only a very light layer of CV-1161 ever be applied to skin, and that the primer never be inhaled or ingested.
After prepping, the silicone mixture may be applied to the patient's skin in different ways. First, the mixture may be applied directly to the skin as the mixture is extruded from the tips 113 of the dispenser 100 . Alternatively, the mixture may be squeezed onto a dish (not shown) and then applied to the skin by use of a spatula (shown at 740 in FIG. 7 ) or other tool. Alternatively still, the mixture may be squeezed into the user's hand or into a dish, and then applied to the area of concern by hand. In any instance, the silicone mixture takes about 5 to 10 minutes to cure. Upon curing, the mixture constitutes a solid synthetic elastomer. Where a primer is used, the resulting translucent elastic layer will stay on the patient's skin for several days, even if the user takes a shower or goes swimming.
The cosmetic system may also comprise a skin texturing pad. FIG. 5A presents an illustrative skin texturing pad 500 A. The skin texturing pad 500 A defines a thin, flexible substrate 502 A having a plurality of dimples 504 A. In the arrangement 500 A, the dimples are large, and may be used to provide texture to a user's hand, arm, legs or foot, for example. Thus, the pad 500 A has a texture designed to match the porous pattern of the dermatological area of interest.
A separate skin texturing pad may be used on dermatological areas having finer features. FIG. 5B presents such a skin texturing pad 500 B. The skin texturing pad 500 B again defines a thin, flexible substrate 502 B having a plurality of dimples 504 B. However, in the arrangement 500 B, the dimples are more subtle, and may be used to provide texture to a user's face, neck, or stomach, for example. In either instance, the use of a skin texturing pad 500 A or 500 B tends to reduce the shine or light reflection from the cured silicone material.
The pads 500 A, 500 B are preferably fabricated from urethane. Pads may optionally be acquired from Smooth-On, Inc. of Easton, Pa. After the pad 500 A or 500 B has been applied to the silicone, it is carefully removed. A matte skin cover disguising a dermatological blemish is left. The final material is dry to the touch, transparent, water resistant, durable, flexible, and has a natural texture. Under normal conditions it is anticipated that the dried material will last up to 72 hours.
It is preferred that the components of the cosmetic system are provided or sold as a kit in a single package. The packaging is referred to herein as a box. An illustrative box is shown in FIG. 6 at 600 . The box 600 includes walls 610 and a lid 620 .
It is understood that the term “box” includes any form of suitably-sized packaging. A box is not limited to a traditional cardboard or plastic box having a lid, although such is preferred; instead, the term “box” may also include a blister pack or a bag.
In any aspect, the box 600 holds the various components making up the cosmetic system. These may include:
a dispenser (such as the syringe 100 ); at least one volume or cartridge containing the silicone material (such as volume 112 ); at least one volume or cartridge containing the catalyst material (such as volume 114 ); a plurality of mixing tips (such as removable tip 150 ); the skin prepping solution provided in a tube or bottle; and one or more skin texturing pads, such as pads 500 A, 500 B.

FIG. 7 is a collection of components that may be included in the box 600 (or other package) of FIG. 6 , for a cosmetic system. FIG. 7 first shows a set of three syringes 710 , 720 , 730 . Each syringe 710 , 712 , 730 includes a pre-loaded volume containing a tinted silicone material. Volume 712 a is tinted to match a first selected skin tone; volume 712 b is tinted to match a second selected skin tone; and volume 712 c is tinted to match a third selected skin tone. In this way, the user may experiment with the different syringes 710 , 720 , 730 to determine which one most closely approximates their own skin tone. Preferably, the box 600 will include three or even more sets of cartridges containing the viscous silicone material.
Each syringe 710 , 712 , 730 will also include a volume containing a catalyst. This is shown at 714 . The volumes 712 , 714 then each have a nozzle 713 through which viscous material is extruded, and a plunger 715 . A band 711 and a plate 716 connect the cartridges 712 , 714 together, along with a push-end 718 .
FIG. 7 also shows a spatula 740 . The illustrative spatula 740 has a body 742 by which the spatula 740 is held. The spatula 740 also has a tip 744 for further mixing a silicone-catalyst mixture and applying the mixture onto the user's skin. Preferably, a cosmetic kit will have two or more spatulas 740 .
FIG. 7 also shows a mixing tip 750 . More specifically, several disposable mixing tips 750 are shown. These removably attach to the tip of the dispensing gun or to the tips of the cartridges 712 , 714 to cover the nozzles 713 .
Finally, FIG. 7 shows a bottle 760 . The illustrative bottle 760 holds a skin prep solution. It is understood that the skin-prep solution may alternatively be held in pre-soaked wipes or tubes (not shown).
Based, on the above-described cosmetic system and components, a method is provided herein for disguising dermatological blemishes on a human user. In one aspect, the method includes providing a package containing a cosmetic system. Generally, the system will include a viscous silicone material and a catalyst. The silicone material, the catalyst, or both is preferably tinted with a pigment according to a desired skin tone. In one aspect, the cosmetic system also includes a flocking agent. The flocking agent is pre-mixed with the silicone material or the catalyst (or both) to provide texture.
The package may also have at least one skin texturing pad. The skin texturing pads are textured in accordance with the dermatological area of interest. Ideally, the pads are created from molds that, in turn, have been created from impressions taken on actual physical skin.
The method also includes mixing a portion of the silicone material and a portion of the catalyst to form a silicone mixture. Preferably, the silicone material and the catalyst are simultaneously extruded from a dispenser. A removable and disposable mixing tip is provided through which the silicone material and the catalyst may be dispensed, whereupon the silicone material and the catalyst are mixed for curing. The viscous mixture of silicone material and catalyst is applied to a dermatological area of interest, either directly onto the user's skin or by using a tool such as a small spatula.
In one aspect, the method also includes applying one of the at least one skin texturing pads to the silicone mixture before the silicone mixture cures. This creates texture to the silicone material. The method may include selecting a particular texturing pad having dimples to match a skin pattern of the dermatological area of interest.
Using the texture pads, a user is able to impart texture to the silicone mixture to the mixture before it cures. In this way, the mixture creates a seamless blend between the defect site and the surrounding flesh as it cures. Even the non-artist can obtain a nice blend into the skin with little to no training. The skin texturing pad is then removed from the user's skin before the silicone mixture fully cures.
The method then includes allowing the silicone material to cure on a skin surface of the human user. The silicone mixture becomes bonded to the user's skin.
The package may optionally have a skin prepping solution. The method then includes the step of applying the skin prepping solution to the dermatological area of interest. The skin prepping solution is applied prior to applying the silicone material to the dermatological area of interest. In one aspect, the skin preparation creates a thin film of silicone that enables the silicone material from the dispenser to stick firmly to the skin. In another aspect, the prepping material helps to remove any oils or dirt that may be present on the skin which may interfere with adhesion. A cotton ball or cloth may be used for wiping the skin with the prepping solution.
In this method, it is preferred that the silicone material and the catalyst are provided in separate but connected volumes of a syringe. Preferably, the volumes are sized such that the silicone material and the catalyst are dispensed in substantially a 1:1 volume ratio. In one aspect, the user selects from a first syringe, a second syringe, and a third syringe in a package, wherein each of the first, second, and third syringes has a silicone material that is tinted according to a selected skin tone. Each of the first, second, and third syringes includes a volume of catalyst material. In this way, the user may create a cured, translucent covering that is tinted most closely according to their skin.
In one aspect, the user chooses a set of syringes from three or more different sets of syringes. For example, a first set of syringes may be tinted for Caucasian skin tones, a second set of syringes may be tinted for ethnic skin tones, and a third set of syringes may be tinted for Asian skin tones. Each of the three sets, in turn, has three or more syringes offering light, medium and dark tints. Thus, the user may select a package containing either Caucasian, ethnic, or Asian skin tones, and then within that package select from the light, medium or dark tinted syringes. The patient selects the “kit” that most closely matches his or her skin tone.
The method may also include applying facial makeup to the dermatological area of interest prior to applying the silicone mixture to the dermatological area of interest. It is noted that the silicone material dries translucently, and additional makeup need not be placed over the silicone material. However, it is also within the scope of the present disclosure to provide a silicone-based makeup that covers over the cured elastic silicone layer. The custom blend of the silicone material, the catalyst and the pigment is preferably designed so that an element of translucence is maintained. Ideally, the cured silicone mixture should not interfere with the user's skin appearance, but should blend in so as not to be notice. However, in some instances a user may have a scar that has left a different skin coloration than their natural skin. In this instance, the user may choose to use a special makeup that blends in the color of the scar tissue with the surrounding skin.
Ancillary to the cosmetic system is a consideration as to pigmentation for users in the market place. The human race presents a true “kaleidoscope” of colors. In one aspect, it is desirable to select a minimum number of pre-mixed syringes which nevertheless support the “skin kaleidoscope” presented by the marketplace. In another aspect, it is desirable to offer a color-matching system wherein a silicone material is custom blended specifically for an individual user by using a computer-driven color matching system.
The foregoing description and examples have been set forth merely to illustrate the inventions herein and are not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the inventions may occur to persons skilled in the art after reading this disclosure, the inventions should be construed broadly to include all variations falling within the scope of the appended claims and equivalents thereof.
For example, it is within the spirit and scope of the present invention to dispense and mix the silicone material and the catalyst manually. The silicone material and the catalyst may be provided as part of a cosmetic system in separate jars or bottles or in separate pump containers. The jars may be sold, for example, in a bundled manner, or sold separately. In any event, the silicone material and the catalyst are preferably mixed at substantially a 1:1 ratio by volume in order to form the silicone mixture.
