"I thought the skin couldn't be pierced"... This thing inside the tissue enters the bloodstream

What... what should I use...

It would be best to avoid wiping your face as much as possible with wet tissues.

Although they say they use wet tissues, since facial tissues are also available, the substances that are not good are probably similar to those in wet wipes, just less so.

Dental floss, cosmetics... if only everything were included... Sigh...

Should we hope that human skin and the human body become accustomed to PFAS so that it doesn't have a significant impact? ㅠ_ㅠ

PFAS, known as "forever chemicals," can be found in a variety of everyday products ranging from toilet paper to food packaging, cosmetics, and dental floss. PFAS that enter the body through various routes have traditionally been believed unable to penetrate the skin barrier.

However, a study published in "Environmental International" has confirmed that PFAS can pass through human skin and enter the bloodstream.

Researchers at the University of Birmingham in the UK analyzed the absorption of the 17 most widely used PFAS using a 3D human skin model. The study found that 15 of these chemicals are absorbed through the skin. In particular, PFAS with shorter molecular structures were found to be more easily absorbed by the skin.

Dr. Odney Ragnarsdottir, a researcher in trace chemical analysis at the University of Birmingham, said, "It has been thought that permanent chemicals cannot pass through the skin barrier due to their electrical charge that gives them the ability to repel water and stains." She added, "However, this theory is not always true, and in fact, absorption through the skin can be a major cause of exposure to these harmful chemicals."

PFAS decompose very slowly over time and remain in the surrounding environment. According to a 2023 study by the United States Geological Survey, nearly half of the tap water in the United States is contaminated with some form of PFAS.

Dr. Mohamed Abdulla, a co-author of the study, stated, "Our research provides the first insight into the importance of the skin route, which is a pathway for exposure to a wide range of persistent chemicals," and added, "Considering the large number of existing PFAS, future research should aim to assess the broad risks of these toxic chemicals rather than focusing on one chemical at a time."
