PFOA can be absorbed from ingestion and can penetrate skin. [16] The acid headgroup of PFOA enables binding to proteins with fatty acid or hormone substrates such as serum albumin, liver fatty acid-binding protein, and the nuclear receptors PPARα [43] and possibly CAR. [126] In animals, PFOA is mainly present in the liver, blood, and kidneys. [16]
“A significant fraction of short-chain PFAS deposited on the skin can migrate into the dermis, and some fraction will actually enter the bloodstream after passing through our skin,” Peaslee says.

Trifluoroacetic acid, a moderately strong acid useful in organic chemistry. Heptafluorobutyric acid, a moderately strong acid that is useful in organic and analytical chemistry. Pentafluorobenzoic acid, a moderately strong acid of interest in research community. Perfluorooctanoic acid (PFOA),a surfactant used to make fluoropolymers such as Teflon.
Before any potential benefits appear, the procedure reportedly initially leaves small, raised bumps under the skin, creating a temporary honeycomb-like texture. This effect has led some to ...
