These work best with whiteheads or freshly expressed ones. Once it drained out the purulent material, you'll see the patch puffs up and that's how you know it worked!
I use it whenever the pimple has come out and it stops me from touching my skin and helps to get rid of the gunk. They are on the thick side so I tend to use it when I know I'm going to be home all day or before I sleep
cosrx never goes wrong. every time i have a big pimple or popped pimple, ill stick one on and leave it on overnight and the next day its healed or the pus is on the patch
I've purchased this product many times, its a life saver.
This always works well on the larger pimples u feel are under the surface of ur skin that is filling up with nasty puss (not helpful for whiteheads/blackheads) after sticking them on at night u can notice a difference in the size.
This is one product that I absolutely cannot live without. They really reduce your pimples and suck out all that gunky stuff OVERNIGHT. Didn't know I needed these in my life until I found them. Amazing.
I have gone through a lot of these, and I remain a fan. It calms pimples, and prevents them from becoming full blown ones.
I use the black ones when I need more transparent patches.
