News of the lawsuit is calling into question the safety of the materials in the undergarment.
Its also highlighting just how hard it is to know whether or not period underwear has PFAS.
“But Thinx didn’t think it was that big of an issue.

Verywell / Thinx
The settlement seems a bit like karma.”
Consumers are often tasked with avoiding PFAS on their own.
People who wear Thinx period underwear could be exposed to PFAS through direct skin contact.
The risk for dermal absorption is potentially higher, because its an area that is more susceptible for absorption.
As a result, its difficult to limit PFAS exposure (though the Environmental Protection Agency is trying).
The easiest thing to do is to advise avoiding the chemicals altogether.
Thats no easy ask.
“As soon as the studies come to light, there is market demand away from using PFAS.”
Without regulation, it is unclear just how many common clothing items may contain PFAS.
Thanks to period underwear litigation, Peaslee thinks we’ll see real change sooner rather than later.
Because of these positives, Mooshian isnt sure if she will stop using Thinx despite the lawsuit.
PFAS is terrifying, Mooshian said.
Is it upsetting to find PFAS in a menstrual product and something I wear my body?
Do I also know its in literally everything else in my life?
Pads and tampons can also contain harmful chemicals, which Mooshian said she’s been trying to avoid.
For me, its kind of like whats the lesser evil?
Is Any Period Underwear PFAS-Free?
Its near impossible to ensure a piece of clothing is PFAS-free.
But independent investigations, like the article that prompted the Thinx lawsuit, are helping.
