When you’ve got a zit, the last thing you want to do is pick it or pop it, irritate it or push the bacteria into your skin even more. What you really want is for something to gently and effectively suck all the pus, bacteria and dead skin cells out of your pore and help the skin heal fast. These handy patches, another Korean skincare innovation like sheet masks, do just that. And it's as simple as slapping on a sticker.

Unlike spot treatments, these patches won't rub off or dry out your skin. The adhesive nature keeps the active ingredients right where they're supposed to be and prevents dirt and other bacteria from further inflaming an angry zit. How do they work? Most are small hydrocolloid bandages, which means they're designed to absorb fluid from the pimple. And you can see them working. As the patch absorbs your zit's grime, the patch expands and turns white (trapping all the bad stuff inside). After wearing the patch for a few hours or overnight, you'll peel it off and the skin underneath will be flatter and much less inflamed.

It's best to keep these on hand, before you actually need them. That way, when you notice a zit forming in its early stages, you can slap one of these on and kill it before it becomes a serious, painful problem. But now there are a handful on the market, so we've pulled together the most effective for a range of skin needs.
