Perilous Penetration: PFAS Found to Breach Skin Barrier
Per- and polyfluoroalkyl substances (PFAS), the notorious “forever chemicals,” have infiltrated virtually every aspect of modern life. These persistent compounds are found in everything from school uniforms and food packaging to cosmetics and waterproof gear. While their presence in our environment and even our bodies has been well-documented, new research reveals a previously underestimated pathway of exposure: absorption through the skin.
The Unsettling Discovery: PFAS Penetrate Skin Barrier
A study published in the June issue of Environment International has revealed that certain PFAS can permeate the skin barrier. Environmental chemists from the University of Birmingham in England exposed 3D human skin models to a variety of PFAS and observed that several compounds successfully crossed the barrier, potentially entering the bloodstream. This discovery raises significant concerns about the health risks associated with these chemicals, as they have been linked to various adverse health effects, including cancer, liver damage, and immune system suppression.
The Ubiquity of PFAS: A Legacy of Convenience and Consequences
PFAS have been a ubiquitous presence in consumer products since their mass production began in the 1940s. Their unique properties, such as water and stain resistance, have made them invaluable in numerous applications, from nonstick cookware to waterproof clothing. However, the persistence of these chemicals in the environment and their potential for bioaccumulation have raised alarm bells among scientists and public health officials.
A New Pathway of Exposure: Skin as a Gateway for PFAS
While previous studies have hinted at the possibility of skin absorption, research has been limited and inconclusive. The recent study conducted by Harrad, Ragnarsdóttir, and Abdallah provides the most comprehensive evidence to date, demonstrating that PFAS can indeed penetrate the skin barrier. This finding highlights the need for increased awareness and caution regarding the use of products containing PFAS.
Uncertainties and Future Research: The Road Ahead
Although the study’s findings are alarming, there are still uncertainties regarding the extent to which PFAS are absorbed through the skin in real-world scenarios. Factors such as skin thickness and the concentration of PFAS in products may influence absorption rates. Further research is needed to quantify these effects and assess the potential health risks associated with dermal exposure to PFAS.

Summary
The recent discovery that PFAS can be absorbed through the skin has raised significant concerns about the health risks associated with these ubiquitous chemicals. While further research is needed to fully understand the implications of this finding, consumers are advised to be mindful of PFAS in products they use on their skin and take steps to minimize exposure. The long-term consequences of PFAS exposure remain a subject of ongoing research, but the evidence suggests that these “forever chemicals” pose a significant threat to human health.
