Sunscreen with UVA & UVB Logos

Sun protection is guaranteed by synthetic filters and/or mineral sunscreens. Some of them protect against UVBs, others against UVAs, and a few against both types of UV rays. Some of them can be used in the form of nanoparticles, while others are suspected of acting as endocrine disruptors, of having a more or less strong allergenic potential, or of being harmful for aquatic environments… Those that are authorized in cosmetics are assessed by European scientific experts and their conditions of use are detailed in Annex VI of the Cosmetics Regulation. But all this does not prevent the recurring controversies on their possible hazards… Here is a presentation of the main substances used, together with their characteristics, regulations, and data available as regards their safety.
