"i had cystic acne on my jaw line and cheeks from almost 2 years. have been using many medications like benzoyl peroxide creams, salicylic acid and over the counter creams. but nothing was working out. 2 months back i went to another dermatologist and she prescribed me aczone cream to use 2 times a day. 
it really worked for me.  within 2 weeks i can make out the difference. new acne almost stopped appearing and even the acne that is trying to come out is clearing up fast. i am so happy that my skin cleared up pretty soon. but if i stop using it for few days, acne start coming back again. also the scars are still there. i think they are fading a little, but still not completely. i am happy my doctor prescribed me this."
