if you go see a dermatologist and you have a breakout, ask for benzac a310. its prescription only, but my dad fills it out, even though he’s not a dermatologist, because i don’t have the opportunity to go to the clinic every time the bottle gets depleted. you put it on every night before bed and it prevents and clears breakouts. it has very strong bleach in it, so make sure that you wear a white shirt and sleep on a white pillowcase.
