Tretinoin
"Okay, firstoff, you aint got patience you keeping that acne ! Like boi, i started breakin out in the beggening of 7th grade then my face started being so greasy and you could easily see my pimples, my doctor recomended the trenitoin cream and so i didnt worry much about my acne at that time so i only applied it like once a week cause i kept forgeting but when i actually applied it each night my face started being so dry and peeling it was embarrasing it lasted for about a week so then , in the middle of 8 grade i still had that same acne so i actually got my lazy butt off everynight to apply it and lets just say it takes about 1-2 months depending on how bad ure acne is to see results, just takes time dont give up"
