American Academy of Dermatology Comments on a Study on the Absorption of Sunscreen Ingredients


eMediNexus Editorial    10 February 2023

The study "Effect of Sunscreen Application Under Maximal Use Conditions on Plasma Concentration of Sunscreen Active Ingredients", published in the Journal of the American Medical Association, describes the potential for certain sunscreen ingredients to be absorbed into the bloodstream. However, it was a small pilot study, which must be backed by more research before determining any harmful effects of the absorption of sunscreen ingredients on a person′s health. 


These sunscreen ingredients in question have been used for several decades without any reported internal side effects in humans. Notably, the study authors conclude that the findings about ingredient absorption must not refrain individuals from using sunscreen. This advice is further supported by the American Academy of Dermatology (AAD), which regards sunscreens as a component of a comprehensive sun protection plan as they have been shown to reduce the risk of skin cancer in several scientific studies.


The AAD encourages the public to continue following sun protection behaviors by seeking shade; sporting protective clothing, comprising a lightweight, long-sleeved shirt, pants, a wide-brimmed hat and sunglasses and generously applying a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher to exposed skin.


These sun protection recommendations by AAD are backed by scientific evidence and current FDA regulations and guidelines.
