Pros: these are adorable, and they keep my fiancee and I (both with dermatillomania) from picking at spots. They're great for keeping a spot covered. Cons: not only are these packaged with so much unnecessary plastic, they aren't as effective as other hydrocolloid patches I've tried. I think it might be something about the shape? Other star shaped patches still don't seem to work well, but the clear circles/squares and some heart shaped ones I tried work better. If you are looking for something to actually suck the gunk out of a zit overnight, the clear ones are better and less expensive (plus you get that gross satisfying moment post-removal where you get to see what all came out of your skin, which these don't really have.) Cute, and I will use the rest of the package, but probably will not purchase again.
