The present invention relates to a cosmetic composition containing a combination of at least one dibenzoyl- methane derivative, and of at least one particular neutral N-acylamino acid ester derivative chosen from compounds (a) to (f ) below: (I). The invention also relates to a process for radiation- photostabilizing at least one dibenzoylmethane derivative with an effective amount of at least one particular neutral N-acylamino acid ester, derivative of formula (a) to (f ). The present invention also relates to the use of at least one particular neutral N-acylamino acid ester derivative of formula (a) to (f) in a composition comprising, in a cosmetically acceptable support, at least one dibenzoylmethane derivative, for the purpose of improving the efficacy of the said composition with respect to UV-A rays. |
