This is my second time buying, I think they're really effective in what they do, I also think they're just as good as some of the more expensive hydrocolloid brands.

I tend to use them around the time my hormonal acne comes us, when I get those really big, red, angry cysts. How I use them is basically just do my skincare as usual in the evening, but at the end I put on one of these patches and keep them for on overnight. In the morning, the cyst is always at least half the size smaller and there's always gunk on the patch. Then I just let the remaints of the spot breathe and it heals up in the next day or so.

I really do recommend these patches :)
