PRINCIPE ACTIF DÉRIVÉ DE LA BIOTECHNOLOGIE, DANS DES COMPOSITIONS COSMÉTIQUES POUR PROTÉGER LA PEAU DE LÉSIONS INDUITES OU PRODUITES PAR DES RAYONNEMENTS INFRAROUGES
It relates to a lysate of at least one microorganism of the genus Bifidobacterium species, which has been found to be useful as an agent for the prevention and/or treatment of the cutaneous signs of photoaging induced or produced by infrared radiation. It also relates to the use of this biologically active agent in combination with physical, chemical, organomineral, and/or biological filters in order to provide a photo protector of a broad-spectrum which avoids photoaging, allowing the exposition to solar radiation without risk, as well as to compositions comprising these combinations, together with cosmetically acceptable excipients or carriers appropriate for topical application to a person's skin.
