Abstract
(EN)
The present disclosure relates to methods for protecting skin from UV radiation while simultaneously improving the appearance of skin. The methods include layered application of a skin perfecting composition and a sunscreen composition. The skin perfecting composition comprises: (i) about 1 to about 40 wt.% of at least one primary film forming polymer having a Young’s modulus of 0.1 to 50 MPa, and elongation at break >50% and a glass transition temperature of <0°C; (ii) about 1 to about 35 wt.% of at least one pressure sensitive adhesive polymer; (iii) about 1 to about 35 wt.% of soft focus powder; and (iv) water. The sunscreen composition comprises: (i) at least one organic UV filter; and (ii) a cosmetically acceptable carrier.

La présente invention concerne des procédés de protection de la peau contre le rayonnement UV tout en améliorant simultanément l'aspect de la peau. Les procédés comprennent l'application en couches d'une composition de perfectionnement de la peau et d'une composition d'écran solaire. La composition de perfectionnement de la peau comprend : (i) environ 1 à environ 40 % en poids d'au moins un polymère filmogène primaire ayant un module de Young de 0,1 à 50 MPa, et un allongement à la rupture > 50 % et une température de transition vitreuse de <0°C ; (ii) environ 1 à environ 35 % en poids d'au moins un polymère adhésif sensible à la pression ; (iii) environ 1 à environ 35 % en poids de poudre de mise au point souple ; et (iv) de l'eau. La composition d'écran solaire comprend : (i) au moins un filtre UV organique ; et (ii) un support cosmétiquement acceptable.
