These are like the invisible magic pimple fighters. Feel one coming on, pop one of these patches on, leave it and forget it, and Iike magic, your pimple disappears in a few hours. I have forgotten I put one on, no one noticed and my pimple had gone completely in less than 5 hours. No more cystic acnes issues either. Works on all kinds of skin. Fantastic little pimple fighting patch!
