Abstract
The disclosure relates to compositions, films, and methods for improving the appearance of the skin. Compositions comprise at least one thermoplastic elastomer, at least one adhesive polymer, and at least one filler. Methods comprise applying the compositions to the skin to tighten the skin or hide skin imperfections, by forming a film on the skin.
Claims19
A skin tightening composition comprising:
- a. at least one thermoplastic elastomer chosen from amorphous hydrocarbon block copolymers of styrene and monomers of hydrocarbon containing 2 to 5 carbon atoms and comprising one or two ethylenic unsaturations, and having a first Tg below about 0° C., and a second Tg greater than about 25° C.;
- b. at least one adhesive film-forming polymer chosen from polymer particles of C1-C4 alkyl(methacrylate)polymer, stabilized in a non-aqueous dispersion;
- and
- c. at least one filler,
- wherein the ratio of the at least one thermoplastic elastomer to the at least one adhesive film-forming polymer is in the range of about 1:5 to 5:1, and
- wherein the skin tightening composition forms a film having a Young Modulus greater than about 100 kPa.
