We tested it so you don't have to wonder.

Every Rewise strip goes through rigorous independent safety testing before it ever reaches your face. Here's exactly what we found.

Heavy Metal Tested

PFA-Free

BPA-Free

ISO Facility

Most people have no idea what's actually in the adhesive sitting on their lips for 8 hours a night. We did — and we tested every single thing that could be hiding there.

Founder

What we tested. What we found.

The safety bar for adhesive products is low. We ignored it and set our own — testing at parts-per-billion precision using the same instruments pharmaceutical labs use.

Heavy Metals

Lead, cadmium, arsenic, and mercury were tested individually. Result: none detected.

ND Across all metals

Lead (Pb) Clear

Arsenic (As) Clear
