If you have issues with acne (especially those nasty whiteheads) but can't afford all the fancy step by step treatments out there, you at least need to buy this. This truly worked in minimizing my pimples, sucking up the wound and keeping big pimples from getting worse. It really does draw up the puss to the patch! I leave one on overnight and just slowly peel off and then wipe away any remaining puss. I even let my mom who was visiting try it on her pimple and she loved them, so I had to order more!
