Regularly use it.

Very effective 

Love these patches. I would usually put these on my problem spots right before bed. When I wake up in the morning and remove the patches, the swelling of the spot would be less. The only this is to make sure the skin around the area you're putting this on is not oily. I had waken up so many times to see a patch missing form my face, only to find it on my bed or my hair. Besides that I love these patches, I keep buying them.

I bought this one for my little brother who is concern about acne at age 13.

leave this on overnight , the next morning your pimple will be so much flatter and
less red

The acne patch heals my pimple heal faster.
 

i order it many times already. it is really great. and its cheaper than guardian.

I got so suprised by this product and I wasn't really sure if it would work, but it does!

It calmed my pimples and made them less visable so I can't wait to see the results after a longer time of using this. 

useful acne stickers, well treated acne, 12 stickers of different sizes

This is an amazing product! It works really well over-night. 
 

It works best when you have big acne that's about to burst. If it doesn't seems to work for acne that's just pop on your skin. I bought 2 packs; 1 pack I have no complaint about but the other pack it doesn't seems to stick on skin as good as when I first use it. The other problem is that most of the times I notice it leaves sticky yucky when I try to take it off. I thought maybe because of face cream I applied too close to the patch; so the next time I don't apply cream around the patch but the next day it does the same thing leaving weird sticky texture. I haven't seen anyone having this kind of complaint before so I'm not sure what's going on.

I love this product so much! It draws all the oil and sebum out of the pimple and also stop any other bacteria and dirt from coming in as well as your dirty hands from touching it too. I place this on the pimple overnight and sometimes even during the day, I found it most effective when the pimple is at a head.  

I almost use up the entire package just in one week. These patches seem to help my pimples heal faster. 

Love this product only wished there were more patches and i didn't have to buy so many at a time

I can't let them run out, these little patches are life savers. Dries tge pimple way faster and then with the help of the Centella Blemish cream also from COSRX I see it disappear. 

i've repurchased so many times and will probably never stop. works amazingly overnight - even on painful pimples under the skin that you can't pop. just stick one on each pimple before bed (after cleansing and BEFORE any moisturizing products, otherwise it won't stick) and in the morning the pimple is completely dried out and you can see all the pus on the sticker. love this product!

They work sooooo good, they leave my pore ready to remove the grease. Awesome and amazing product.

I love them! If i see a pimple, i put one on and its gone by morning!!
 

There is a difference right away. I usually put it on right before I sleep, so when I wake up theres a satisfaction peeling away and seeing all the oils gone !
