University of Birmingham researchers found PFAS chemicals can penetrate human skin, challenging previous assumptions

These "forever chemicals" were initially known for toxicity and are widespread in consumer products

Recent experiments used a 3D skin model to demonstrate absorption rates of PFAS variants

Out of 17 tested PFAS, 15 were absorbed by the skin model within 36 hours

PFOA, a phased-out PFAS, can still enter the bloodstream and linger in skin

Roughly 13.5% of PFOA applied to the model entered the bloodstream directly

Newer PFAS variants like PFPeA show higher absorption rates into the skin

Studies suggest systemic toxicity of PFPeA in animal models and ethical concerns in human testing

The research highlights concerns over PFAS exposure from everyday products like sunscreen

The study underscores gaps in understanding PFAS health effects and calls for further research
