Have been using this item for many years as it was one of the first to produce the pimple patches. I can honestly say that this reduces the scaring as once u pop the pimple, it will help with getting all that gunk out from your infected pores. It reduces time of healing and so i could never live without this type of product now. It’s a life changer and I now use this on my kids as they are now starting to get acne. I find these patches thinner than the red packet ones. I use both, the black ones during the day so it’s less noticeable and red ones at night during my sleep. Can’t live without pimple patches anymore. Great invention. I find that it sticks the best before you put any skincare products. I normally stick these on right after cleansing and careful with my application around the area post sticking it on.
