'Sunscreen Absorbs Into Your Blood': What That Headline Really Means
Yes, some chemical filters enter the bloodstream, but absorption is not the same as harm, and quitting sunscreen carries its own real risk.
FDA studies found that some chemical filters are absorbed into the bloodstream, but absorption alone does not mean an ingredient is harmful, and the FDA and dermatologists continue to recommend daily sunscreen use.
The American Academy of Dermatology stresses that detecting an ingredient in the blood does not establish that it is unsafe, and that the proven benefit of sunscreen in preventing skin cancer remains.
Questions we get a lot
Does sunscreen really get absorbed into your bloodstream?
FDA studies did detect some chemical sunscreen filters in the bloodstream after use. However, the AAD explains that absorption by itself does not mean an ingredient is harmful or that you should stop using sunscreen. The findings prompted a call for more safety data, not a warning against use.
Should I stop using chemical sunscreen?
Dermatologists do not recommend stopping. The AAD continues to advise daily sunscreen use because protecting skin from UV is proven to reduce skin cancer and premature aging. If you prefer, you can choose a mineral sunscreen with zinc oxide or titanium dioxide, but the most important thing is to keep using sunscreen.
