Tretinoin
"This stuff is amazing. Not only for acne and acne scars, but for its anti-aging benefits too. I experience moderate hormonal acne breakouts on my chin/jaw area. While Tretinoin doesn't exactly stop my breakouts completely, it helps control my skin when I do have a breakout. I feel any pimples clear up and heal much quicker and any spotty discolouration that occurs after spots heal disappears much quicker. This stuff has especially done wonders for fine lines around my eyes and between my brows. My skin tone is more even, pores are smaller and condition of my skin/complexion is far nicer. My skin peeled a lot during the first few weeks- use once every few nights until your skin adjusts. I use nightly now with no problems."
