If you find yourself standing shamelessly infront of the mirror after picking at your face, try sticking on a dot to reduce the blemish as it heals. Or better yet, place one over an emerging pimple to help you urge to squeeze it.

You can cover them with makeup, and they're invisible. Popped zits saw the most improvement - since we couldn't continue to touch them, they had time to heal, and the hydrocolloid sucked up the fluids that had leaked out. 

These are superb if you have a problem with skin-picking. Gives the lesion a chance to heal; when it eventually comes off, you're healed! They stay on for days--often a week, and don't come off in the shower. They are translucent and blend into skin color, so virtually invisible.

I am a physician and recommend these to patients!
