It work alright, but not as good as Cosrx one 

Maybe I need to try them on a different pimple, but on one I had it on didn't help much to reduce the size or redness. On an open one, it did not soak up the sebum like the Cosrx ones do. I LOVE how they're super thin though, you can't see it on the skin except in some lighting so these are good if you want to leave the house and not have bacteria enter your skin or protect a pimple. These, I think, would also be good under makeup. The Cosrx ones are thicker and have a yellow tinge to them so they can be seen on the skin and most likely with makeup over them. I need to try these on different pimples to see if I repurchase again but so far it's a no other than if I start wearing makeup :)

Help prevent myself from touching my pimples :)

Amazing product...
