If you leave it on overnight you can see some shrinkage of pimples!

It does what it claims to do! very good.

This is the best and most effective way of treating a pimple, especially overnight. Take a bow Corsx!

A buy a few of these with every StyleKorean order. I don't really have any major acne issues, however when the odd pimple pushes through these patches are the most effective treatment for my dry skin. The only way that this product would be better is if there were more patches per packet.
