Forever chemicals are absorbed through human skin

A recent study conducted by the University of Birmingham has confirmed that perfluoroalkyl substances (PFAS), known as 'forever chemicals,' can be absorbed through human skin. These toxic substances, commonly found in various consumer products like waterproof clothing and personal care items, are known for their water and stain repellent properties. The research, published in Environment International, revealed that PFAS can permeate the skin barrier and enter the bloodstream, contradicting the previous belief that they could not breach the skin membrane. The study, which used 3D human skin equivalent models, found that 15 out of 17 PFAS tested showed substantial dermal absorption, with some chemicals being absorbed at higher rates than others based on their molecular structure. The findings highlight the importance of considering dermal exposure to PFAS and the potential risks associated with these chemicals, especially as industries shift towards using PFAS with shorter carbon chains believed to be less toxic but potentially more easily absorbed.
