acne
"Epiduo hurt. And stung. It hurt when I put it on, it hurt when I put on lotion, and it hurt when I tried makeup. I only put it on at night; washed my face, put on the epiduo for 15 min, then covered myself in Nivea Soft lotion.  (the one that stung the least $4.99) 
Today is day 18 and I am THRILLED! I only have scars, which are fading day by day. My skin is still peeling and stings! But it's tolerable. I haven't worn makeup to college or work for the past 3 days for the first time in my entire life, and I looked fine. A guy even hit on me in the parking lot!!! I will continue to use Epiduo even if the peeling face never goes away. It's done wonders! 
I'll wait another month and post on here again for the same results. STICK TO IT! TRUST!"
