Can someone explain the sorcery, or science, behind the small acne stickers that teenagers everywhere swear by now. Thanks!
In: Biology
Hydrocolloid bandages (which is what those stickers are) absorb pus and other gunk from wounds, which makes them very useful when you’re trying to flatten a pimple or drain a cyst. But there needs to be some way for the drainage to escape, i.e. an opening in the pimple. Just sticking a sticker on top isn’t going to get any of the gunk out.
