These are the best pimple patches. I would say, they work most effectively on open pimples, sucking up all the pus, reducing redness and healing the skin around the pimple. Will definitely repurchase them! 

THIS PRODUCT IS AMAZING! I always have that problem of wanting to pop my pimples (Ew.. I know), but after getting introduced to this product it has saved my skin!!! If you have acne prone skin and have pimples here and there try this item out. Although, it may have taken me a few tries to really like this item I don't think I'd stop buying this product now. Go COSRX!
