“According to that study, nearly half of the 500 most popular sunscreens may actually increase the speed at which malignant cells develop and spread skin cancer such as melanoma.
Why? Because they contain Vitamin A, an ingredient that was added to sunscreen formulations because it’s an antioxidant that slows skin aging.
This isn’t necessarily new information….as some studies suggest “that vitamin A might have some phototoxicity.”
Take it easy folks. One study on the effects of Vitamin A on skin cancers in animals does not invalidate sunscreen use. We don’t really need Vitamin A in sunscreens though. We need good blockers of UVA and UVB at an SPF of at least 30.
