Sunscreen can be absorbed in the bloodstream, says new study

Sunscreen is one of the best ways to protect against the sun’s potentially dangerous ultraviolet rays.

The effects of sunscreen’s ingredients on our body is still unknown, but a new study published in the medical journal, JAMA, finds that certain active ingredients can be absorbed into the bloodstream after use.

“Results from our study released today show there is evidence that some sunscreen active ingredients may be absorbed. However, the fact that an ingredient is absorbed through the skin and into the body does not mean the ingredient is unsafe,” said Dr. Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research, in a recent press release.

There are two main types of sunscreen sold to consumers.

Mineral sunscreens sit on top of the skin and reflect the rays away but leave a white residue on the skin and can wash off with sweat and water.

Chemical sunscreen goes on easier and absorb into your skin. These chemical sunscreens are the ones that have now been confirmed to enter your blood stream, but it is still unknown if this is cause for concern. Woodcock says, “This finding calls for further industry testing to determine the safety and effect of systemic exposure of sunscreen ingredients, especially with chronic use.”
