This did not stick to the skin. Worked fine for pimples, but had to use a band-aid over it to get it to stay on the face.

These are really good at targeting the big under the skin zits. But I do find them really expensive for what you get. I also don’t like how much packaging is used. 

I have cystic acne and this product is a game changer. I have used many acne patches so far, cosrx etc., but none of them are as effective as this product. I will keep buying it.

I hate that this product is quite expensive per patch and you definitely need more than a patch to deal with a painful underskin zit. However, as soon as you get this sort of zit, this is the remedy. For me, it dissolved practically every zit like this and this makes the price worth it. Try buying a small pack if possible to check it out for yourself.

It is very effective for cystic acne and I keep buying it
