ABSTRACT
Skin exposure to acute or repetitive ultraviolet light induces risks which are now well identified.
An efficient photoprotection is thus required for both UVB and UVA radiation. In particular,
increasing evidence of the detrimental effects of UVA on skin has led to the development of
a new generation of sunscreens that provide effective protection throughout the whole UV
radiation spectrum. Many new UV filters have been introduced in the last decade, particularly
UVA filters, with improved efficacy and safety. Sunscreen filters must be carefully combined to
achieve esthetically pleasing products offering photostable and well-balanced photoprotection.
