(en)BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to cosmetics, and more particularly but not by way of limitation, to a skin care cosmetic regime and components used therein.
2. Brief Description of Prior Art
Skin care cosmetics, such as hand creams and lotions, have heretofore been employed to soften a person's skin, deter aging of the skin, and generally improve the overall health of the skin. Normal, healthy skin undergoes a natural renewal cycle wherein cells are constantly being produced or born, rise to the skin's surface through the epidermal layers, and then fall off. This renewal cycle for young skin is much more rapid than for mature skin. For example, healthy, young skin will normally renew itself every two weeks or so; whereas, healthy mature skin will renew itself about every four to six weeks.
In order to provide mature skin with a younger looking appearance, to retard aging spots and to soften the skin, it is desirable to accelerate the natural cell renewal cycle which results in the replacement of dead cells by new ones in the outer epidermal layer or stratum corneum. However, care must be exercised in accelerating the cell renewal cycle because irritation of the skin may occur due to the sloughing off of the dead stratum corneum cells, and such irritation may damage the skin.
The prior art is replete with cosmetic preparations, especially skin cream formulations and cell renewal cosmetic formulations for increasing the epidermal cell turnover without skin irritation. Typical of such prior art is as follows: Van Wessem et al., (U.S. Pat. No. 3,227,616); Sutliff et al., (U.S. Pat. No. 3,810,996); Hasunuma et al., (U.S. Pat. No. 4,000,276); Vargas et al., (U.S. Pat. No. 4,268,526); Cella et al., (U.S. Pat. No. 4,272,544); Flom et al., (U.S. Pat. No. 4,368,187); Herrold U.S. Pat. No. 4,581,230).
Many of the before-mentioned prior art references use a multiple component system containing components of various ingredients in the formulation of cosmetic preparations for use in a cosmetic skin regime. However, because of the concern for healthy and younger looking skin, especially as same relates to a person's hands and face, new and improved cosmetic preparations are constantly being sought which will accelerate the cell renewal cycles of mature skin without causing irritation. It is to such a cosmetic formulation and cosmetic regime that the subject invention is directed.
SUMMARY OF THE INVENTION
According to the present invention an improved and unique cosmetic formulation for use with a skin care cosmetic regime is provided for accelerating the cell renewal cycle of the skin to provide healthier, younger looking skin. The cosmetic formulations, which are employed in selective sequences in the skin care regime for sensitive skin, such as a person's face, include a softener component, a cell penetrating component, and a nourishment and protectant component. When utilizing the cosmetic formulations for less sensitive areas of the skin, such as a person's hands, the skin care regime further includes the application of a fourth component, namely, a sealant and skin tightener. Each of the components used in the skin care regime, and constituting the cosmetic formulations of the present invention, is formulated of specific ingredients to achieve the desired function in the conditioning of a person's skin.
An object of the present invention is to provide an improved skin care cosmetic formulation which increases epidermal cell turnover without irritation to the skin.
Another object of the present invention, while achieving before-stated object, is to provide an improved cosmetic formulation and skin care regime for the skin so as to deter aged spots, aging of the skin and generally improve the overall condition and health of the skin.
Other objects, advantages and features of the invention will be apparent from the following detailed description when read in conjunction with the appended claims.


DESCRIPTION
The skin care cosmetic formulations of the present invention comprise a plurality of components which are sequentially used in a skin care cosmetic regime. For example, when treating sensitive areas of the skin, such as the skin about a person's face, the skin care regime comprises application of a three component cosmetic formulation, namely, a softener component, a cell penetrating component and, a nourishment and protectant component. However, when employing the skin care cosmetic regime for treatment of less sensitive areas of he skin, such as the skin of a person's hands, it is desirable to include the regime the application of a fourth component, namely, a sealant and tightener component. In such instance the skin and tightener component is applied to the skin after the cell penetrating component and before application of the nourishment and protectant component.
The components of the skin care formulations of the present invention are prepared using specified ingredients, and are formulated using selected processing steps and conditions. The composition and formulation of each of the components is as follows:
SOFTENER COMPONENT
The softener component of the cosmetic preparation consists essentially of the following ingredients. It should be noted that the softener component is desirably used on extremely dry, rough skin of the body and is formulated to function as a massage vehicle. In formulating the softener composition that the amounts of the ingredients can vary within the ranges setforth, provided that the total weight percentages of the ingredients equal 100 weight percent of the softener component. Further, the column entitled "Experimental" is setforth as an example of a desired formulation of the softener component for use in the skin care regime of the present invention.

The nourishment and protectant component of the cosmetic formulation is prepared as follows: The ingredients are weighed, and thereafter the ingredients of part A are introduced into a vat and heated to a temperature of from about 70° to 93° C. The ingredients are constantly stirred during the heating phase, as well as during addition of the ingredients constituting Part B and C as will be setforth hereinafter. Once a substantially homogeneous mixture is formed at the temperature specified, the mixture is allowed to cool to about 30° C. Thereafter, the constitute of part B and C are admixed sequentially with the mixture formed of the ingredients of Part A and stirring is continued until a homogeneous mixture is obtained. The nourishment and protectant component so formed is removed from the vat and placed into suitable containers or dispensers.
In the cosmetic skin care regime employed for portions of the body having less sensitive areas of skin, such as a person's hand, foot, arm and the like (hereinafter referred to as "hands"), the first step of the regime is the application of an effective amount of the softener component to the hands to effectively cover the skin being treated. Once the softener component has been applied to the hands the skin is massaged for approximately two to three minutes, concentrating on dry, callus areas. When applied to the hands, attention should be paid to the cuticle area around the nails to insure softening of the cuticle area. Massaging of the skin is continued until the detected dry areas begin to soften. Once the softening of the dry areas of the skin on the hands is detected, the hands having the softener component thereon which has liquified as a result of the body temperature and the massaging action, are immersed in warm water and rinsed well to remove the softener component from the surface of the skin. Once rinsed, the skin is dried by any suitable means, such as by patting dry. It should be noted that because the top layer of skin is generally hard to penetrate, the softener is used to soften and prepare the skin to allow the other components of the cosmetic formulation used in the cosmetic skin care regime to penetrate and effectively assist in the cell renewal cycle of the skin. Further, the use of the softener removes undesired residue from the skin, such as dirt, oil and other impurities.
The second step of the cosmetic skin care regime is the application of the cell penetrating component to the hands cleaned with the softener component. A liberal amount of the cell penetrating component is massaged into the hands. The amount of the cell penetrating component applied will vary, depending on the condition of the skin. However, a sufficient amount of the cell penetrating component should be utilized so that after massaging the skin feels "slightly damp". The cell penetrating component is maintained on the skin (whether used in combination with the sealant and tightener component, as on non-sensitive areas of the skin, or without the use of the sealant and tightener component, as on sensitive areas of the skin) for a period of time effective to allow the cell penetrating component to penetrate the cell level of the skin, generally about 10 to 30 minutes.
When applied to non-sensitive areas of skin (i.e. the skin of a person's hands), the third step of the cosmetic skin care regime is the application of the sealant and tightener component to the hands having the cell penetrating component thereon. The sealant and tightener component seals the cell penetrating component and minimizes line formation. The sealant and tightener component can be applied to the hands with a brush, one's hands, or other suitable means, so that the hands are evenly covered in a "glove-like" application. To prevent the sealant and tightener component from attaching to hair on the arm and thereby pulling on the hair as it dries, a ring of the softener component is applied to the wrist prior to application of the sealant and tightener component.
Once the sealant and tightener component has been applied, the person is placed in a comfortable position so that the treated hands can be maintained in an undisturbed position for about 30 minutes to enable the sealant and tightener component to dry. The drying period can be shortened to about 10 minutes through the use of heated air, such as generated by a hair drier, or any other device capable of enhancing the drying of the sealant and tightener component.
Once the sealant and tightener component has dried, a small amount of warm water is applied to form a paste like material with the sealant and tightener component. Thereafter, additional water is applied, along with a massaging action. Finally, the hands are rinsed with warm water to remove any residual sealant and tightener component and dried.
The final step of the cosmetic skin care regime of the present invention is the application of the nourishment and protectant component. The nourishment and protectant component is applied to the hands and massaged into the skin until the amount which can be absorbed by the skin is indicated by a residual amount of the component on the skin. Thereafter, the skin is blotted with an absorbent material to remove the excess nourishment and protectant component from the surface of the skin.
The before-described cosmetic skin care regime employs a combination of unique components, each of which performs a specific function in the region. Further, use of the components in the skin care regime results in healthier skin, better looking skin and deters the formation of age spots as well as aging of the skin.
While presently preferred embodiments of the cosmetic skin care regime and components used therein have been described for the purpose of this disclosure, numerous changes may be made which will readily suggest themselves to those skilled in the art and which are encompassed within the spirit of the invention disclosed and as defined in the appended claims.
