Related: many of the components of sunscreen break down into free radicals in the process of absorbing UV, which are in effect (but perhaps not in practice) more damaging than UV exposure itself. Quick source I dug up, but there's many more (and the industry appears to be aware of this issue and is doing R&D): "Sunscreens Inadequately Protect Against Ultraviolet-A-Induced Free Radicals in Skin: Implications for Skin Aging and Melanoma" [1] [1] https://www.sciencedirect.com/science/article/pii/S0022202X15304437 https://www.sciencedirect.com/science/article/pii/S0022202X1...
