DE FAiLED DESCRIPTION OF THE INVENTfON

[0619] In accordance with the foregoing objectives and others detailed herein, the invention overcomes deficiencies associated with the prior art by providing a system of cosmetic compositions which improves the aesthetic appearance of biological surface resulting from, for example, the chronological aging process, environmental damage to the biological surface, or natural imperfections. The system of cosmetic compositions and methods thereof, once applied to a biological surface or synthetic biological surface, enhances the appearance of the surface by altering the appearance of a biological surface by enhancing diffused transmittance and .reflective properties, thereby improving the aesthetic appearance of the biological surface. The aesthetic appearance of the biological surface, including hut not limited to skin, keratinous tissues, hair, and nails, may he achieved by topical application of the inventive composition to the biological surface on a daily basis or when a natural appearance is desired.

[0Θ20] The inventive system of cosmetic compositions alters the optical properties of a cosmetic composition to provide biding, opacity, coverage, blurring and natural appearance. TSie system of cosmetic compositions comprises two cosmetic compositions, the first composition being a haseeoat and the second composition being a topcoat. The cosmetic compositions present, in the system are suitable for topical skin application. The term "baseeoaf as used herein refers to a cosmetic layer that is applied directly to a substrate. Preferably, the substrate is a biological surface, such as skin The term "topcoat" as used herein refers to a cosmetic layer that is applied on top of a different cosmetic layer. Preferably, the topcoat is applied to the baseeoat,

[0021] The inventive system of cosmetic compositions provides a pigmented basecoat and a diffused topcoat. A pigmented basecoat is used to match the skin tone and to cover blemishes or age spots. A diffused topcoat is used to blur lines and wrinkles. Application of a pigmented basecoat to a biological surface is followed by application of a diffused topcoat to lhe basecoat. The topcoat may be comprised of difmsers, film formers, and a cosmetically or pharmaceutically acceptable carrier. The basecoat may be comprised of a pigment and a cosmetically or pharmaceutically acceptable carrier. The basecoat may be a traditional foundation base,

|OΘ22| Efficiency of blurring or soft focus effect or the ability to hide lines and wrinkles is believed to be a function of the diffused transmitumce parameter ("Quantification of the Soft Focus Effect", Cosmetics & Toiletries; Vol. I l l, July I¹W. p. 57} (the disclosure of which is incorporated herein by reference).

EXAMPLE

[QΘ93] In this example, a system of cosmetic compositions is prepared and tested io measure diffused ttansmiitance and reflectance. The system includes two compositions, a pigmented basecoai and a diffused topcoat. The pigmented basecoat includes titanium dioxide, and is applied to clean glass slides m three (3) thicknesses: 2 microns. S microns, and H) microns. The diffused topcoat is applied to the basecoat. The diffused topcoat includes nylon. The diffused topcoat is applied at a thickness of 10 microns.

[0Θ94] At a basecoat thickness of 2 microns, the pigmented baseeoal and diffused topcoat exhibit a percent diffused transniiuanee of about 30. At a basecoat thickness of 5 microns, the pigmented basecoat and diffused topcoat exhibit a percent diffused transmitlance of about 15. At a basecoat thickness of 10 microns, the pigmented basecoat and diffused topcoat exhibit a percent diffused transmittanee of about 9. These results are reported in Figure 4.

[0095] Further, at a basecoat thickness of 2 microns, the pigmented basecoat and diffused topcoat exhibit a percent reflectance of about 40, At a basecoai thickness of 5 microns, the pigmented basecoat and diffused iopcoat exhibit a percent diffused iransmmance of about 69. At a basecoat thickness of 10 microns, the pigmented basecoat and diffused topcoat exhibit a percent diffused traπsmutance of about 83. These results are reported m Figure 5.
