Cosmetic composition comprising gingko biloba and sunscreen agents

Abstract

A cosmetic composition is provided comprising a Gingko biloba extract, an alkyl beta,beta-diphenylacrylate and / or alpha-cyano beta,beta-diphenylacrylate derivative, and a dibenzoyl methane derivative. A cosmetic use of that composition is also provided for preventing sun damage and photo ageing.

Description

[0001] Technical Field of the Invention [0002] Provided is a cosmetic composition comprising ginkgo extract, β, β-alkyl diphenyl acrylate and / or α-cyano-β, β-diphenyl acrylate derivatives, and dibenzoylmethane derivatives . Also provided is the use of Ginkgo biloba extract in combination with alkyl β,β-diphenylacrylate and / or α-cyano-β,β-diphenylacrylate derivatives and dibenzoylmethane derivatives , to prevent sun damage and photoaging and / or treat sun damaged and photoaged skin. These compositions exhibit better sun protection. Background of the invention [0003] Ultraviolet rays (wavelengths of about 280nm to 400nm) from sunlight are known to cause tanning of the skin. In particular, wavelengths of 280 nm to 320 nm (so-called UVB rays) are known to cause tanning and erythema commonly associated with photoaging. Likewise, prolonged and repeated exposure to so-called UVB rays having a wavelength of 320nm to 400nm is also known to cause tanning, loss of skin elasticity,...
