New Study Confirms Forever Chemicals Are Absorbed Through Human Skin

A study of 17 commonly-used synthetic 'forever chemicals' has shown that these toxic substances can readily be absorbed through human skin.

New research, published in Environment International proves for the first time that a wide range of PFAS (perfluoroalkyl substances)-chemicals which do not break down in nature-can permeate the skin barrier and reach the body's bloodstream.

PFAS are used widely in industries and consumer products from school uniforms to personal care products because of their water and stain repellent properties. While some substances have been banned by government regulation, others are still widely used and their toxic effects have not yet been fully investigated.

PFAS are already known to enter the body through other routes, for example being breathed in or ingested via food or drinking water, and they are known to cause adverse health effects such as a lowered immune response to vaccination, impaired liver function and decreased birth weight.

It has commonly been thought that PFAS are unable to breach the skin barrier, although recent studies have shown links between the use of personal care products and PFAS concentrations in human blood and breast milk. The new study is the most comprehensive assessment yet undertaken of the absorption of PFAS into human skin and confirms that most of them can enter the body via this route.

Lead author of the study, Dr. Oddny Ragnarsdottir carried out the research while studying for her Ph.D. at the University of Birmingham. She explained, "The ability of these chemicals to be absorbed through skin has previously been dismissed because the molecules are ionized. The electrical charge that gives them the ability to repel water and stains was thought to also make them incapable of crossing the skin membrane.

"Our research shows that this theory does not always hold true and that, in fact, uptake through the skin could be a significant source of exposure to these harmful chemicals."
