Photoprotection: update in UV-filter molecules, the "new wave" of sunscreens.

In this review, we provide a wide, non-comprehensive overview of the latest trends in protection against the deleterious effects of the sun. The review is divided into physical blockade of UV photons, UV photon absorption and/or reflection provided by topical sunscreens and topical antioxidant compounds. The last section is devoted to the newest generation of dietary photoprotective compounds. Possible mechanisms, particularly antioxidant, are discussed.
