It's not what I expected according the other reviews, but it is pretty nice product. No magic, but those pimples that are under the skin and have no way out really mature and come to the surface of the skin. Or their "capsule" is significantly reduced in size. But you have to spend not one or even two patches.
These are good for overnight use right at the start of those pesky giant cystic zits that linger. It's not super absorbent like some hydrocolloid patches but it inserts the ingredients right into the monster zit, like a stake in a vampire's heart.
