Tretinoin
"Hi everyone! I'm a sixteen year old girl who has been struggling with acne since the beginning of high school. My self confidence definitely crashed and I always seemed to have to cake foundation on my face before going anywhere, and I just wanted my acne to be GONE. So it has been exactly 2 1/2 months since my physician prescribed me to tretinoin Retin-a 0.05%, and the first thing I did was look up reviews about it. I was terrified of the possible "purge" so I waited until a week long break from school to start using it, and to my surprise, no special purge on my skin! My forehead and chin have always been okay; cheeks and nose have been the biggest problem, but generally my skin is smoother and less red! STICK WITH IT!!!"
