Tretinoin
"My acne got worse in my mid 20s and after trying every tip I could find I finally decided to go to the doctor and he gave me tretinoin . After several research's I found out that things might get worse in the beginning. And indeed things got worse after a few weeks and I broke out terribly, I cried when I looked in the mirror but I thought “just stick with it” and trust me its worth it! I know its really hard but when its over its getting better and better (took me 3-4 months to see first results). Also don't pick because you will have a giant wound after it. Good thing about that; I am not picking anymore :) ! I I also use BP in the morning and zinc, after 11 months I’m now getting compliments for my flawless skin! Don't give up its worth it"
