Tretinoin
"I love this cream. My doctor prescribed this to me for acne (cystic, and blackheads). This was a dream cream for me. I am 23 years old and have been suffering from acne since about 14. Ive never had clear skin since using this stuff - and ive tried every product - even then expensive luxury products. This smoothed my skin after 2 weeks of use, made my hyper pigmentation from years of acne drastically improve. I do understand this is very drying, because it is speeding up creating new layers of skin. Because I don't want to be blotchy with dry patches all the time, I use this cream every other night, and moisturize thoroughly the next morning. I couldn't be happier with this cream because I'm finally able to not wear as much make up!!!!"
