These hydrocolloid stickers are pretty amazing and super sticky, the only caveat is they only work when pimples are at they stage where they're ready to burst out with icky white goo (meaning that they've 'come to head'). I bought the 4 pack and it'll definitely last me a while, but they are a bite pricy compared to the hydrocolloid bandages that you guy can get in the drugstore.... may test them out first when I run out.
