Hydrocolloid patches are some of my favorite products for active breakouts, so I was excited to try something as more of a preventive measure. And it is wonderful!! I noted gradual skin clearing over time, and really satisfying gunky patches overnight. It didn't hurt one bit to remove and did feel comfortable on my nose. It stayed on the whole night without any peeling up from the edges.
I have sensitive skin, and I did experience a slight tingle. But no lasting irritation. And if you don't put it on just right, there may be some gaps between the patch and your skin. But it's easy and sticky enough to redo without issues. It's not an instant fix, but improved over time.
