LOVE these for pimples with a head, and for helping a red spot look less scary (papule pre-pustule). I only like cosrx patches, i find others to have too much gluey adhesive or extra unhelpful ingredients.

Some people complain that pimple patches only work on superficial acne like whiteheads with actual pus, but I think they're also really useful with cysts because not only they will help you out calming the redness around it, but they...

This COSRX pimple patches come in a full variety of sizes for different pimples and they do a really good job absorbing all the junk and soothing the zone. The only think I don't love about them is their thickness: Despite looking perfectly blending with how your skin looks, they are a little bit thick so the edges of the pimple patch are noticeable, even if you wear makeup. So I prefer to use this patches only at home.
