These pimple patches by Thayers are made from 100% hydrocolloid and definitely work in terms of helping speed up the pimple healing process. These pimple patches work best when your pimple is ripe enough. If you stick these pimple patches on when your pimples are not ripe enough yet, they will not do anything, and it would be a waste of a pimple sticker. You know when your pimple is ripe when it comes to a head and has that little white spot. When it's ripe, I would stick this pimple patch overnight and typically by the time I wake up, the pimple patch will have absorbed all the gunk from my pimple. You will know that it worked if you see your pimple patch turn white. Sometimes it might take an extra night for the gunk to come out. When you stick these pimple patches on, make sure your face is freshly washed without any face products or else they won't stick as well. Given what the Thayers brand is known for (natural remedies and herbal extracts), I would think that they would infuse some natural ingredients into this pimple patch to help speed up the healing process even more. But to my disappointment, they did not add any additional active ingredient to this pimple patch despite what their brand stands for so I took off a star.

Great for my teen

We love Thayers everything. They work so great and they truly are invisible. My daughter can wear them to school and not even realize they’re on her face.

A MUST Buy for your TEEN.

Helping my son so much - these work within a couple of hours to flatten ouchie whiteheads. My 14 years old son is so grateful! There’s 2 sizes, 22 patches, and they truly are “invisible” like the box says. These have been working so well (better than any other brand - and we’ve tried them all) and the price is the cheapest. We Love THAYERS brand now - lifetime user here for sure.
