As a research intern at EWG, I’ve investigated sunscreens to learn more about how they work and the claims that companies make. I wondered why I’d been told to put sunscreen on a sunburn, even after I came inside. The answer isn’t soothing. Anti-inflammatory ingredients in sunscreen suppress redness, pain and inflammation, even after skin damage. In other words, the sunscreen makes burned skin feel better temporarily – but it’s still burned.
