More Evidence of Sunscreen Systemic Absorption

Elevated levels of all chemicals and formulations tested, but no evidence of harm

Six ingredients commonly found in sunscreens had systemic absorption levels that exceeded FDA recommendations, according to a clinical evaluation of four sunscreen formulations.

Mean plasma concentrations of avobenzone (primary endpoint) ranged from 3.3 to 7.1 ng/mL across the four sunscreen formulations (one lotion, three sprays). That compared with the FDA recommendation of 0.5 ng/mL.

The other five chemicals evaluated in the study also exceeded the FDA recommendation for each sunscreen that included the chemicals in its overall composition, reported David G. Strauss, MD, PhD, of the FDA Center for Drug Evaluation and Research in Silver Spring, Maryland, and colleagues in JAMA.

“All six sunscreen active ingredients tested resulted in exposure above 0.5 ng/mL, and this threshold was reached after one application to 75% of body surface on day 1,” the authors stated. “This reinforces the need for additional research to determine the effect of systemic exposure of sunscreen ingredients.”

“These findings do not indicate that individuals should refrain from the use of sunscreen,” they added….

It’s very strange, unlike every other purported branch of science, whatever medicine doesn’t know about or bother to research somehow doesn’t actually exist.   Absence of evidence of harm is indeed evidence of absence of harm according to our medical authorities.   Take the FDA’s RDA for vitamin D for instance…
