At Bioderma, we listen to your skin. Photoderm encourages immunity against the harmful effects of the sun, thanks in part to Cellular Bioprotection®. This technology is unique, patented and laboratory-tested. Even after sun exposure and despite its ability to prolong your tan, Photoderm After Sun uses real, biological and internal protection. Our lotion soothes and hydrates to deeply protect the skin integrity. Its formula is enriched with allantoin and Ginkgo Biloba, some emollient agents that calm heating sensations. Glycerin and shea re-moisturize and restructure your epidermis, preventing dryness of the skin due to sun exposure.
