"i&#039;m a 31 year old mom of three, and had been experiencing the worst acne of my life for the past year. i&#039;ve always had acne off and on since a teen, but the past year i had cystic acne along my chin line and under my jaw like nothing else. painful. embarrassing. my doc prescribed this, in the liquid form that you pat on. i use it nightly every or every other night (along with a rx benzoyl peroxide cleanser first). one month down and acne cleared up almost immediately. i will continue using for maintenance of course. i&#039;m sensitive to retin a, this stuff though never leaves my skin dry or burned like retin a did."
