"started in november 2015 when i was 18 and my skin was clear after 4 to 5 months by march of 2016. first few weeks weren&#039;t easy. even with pea sized amounts used every other day, my skin was still itchy and blotchy. but i turned to a cetaphil moisture as an important weapon in the fight. epiduo is strong, and can dry your face out, so use a pea sized amount. if you&#039;re needing a refill every month then you&#039;re using to much. one bottle should last you 3-6 months, not 1 or 2. also, you&#039;ll break out the first month, just because dirt and clogged stuff is being drained. most importantly, don&#039;t bash on epiduo, you might be impatient and want clear skin asap, but you&#039;ll have to learn to add it to your routine and turn to a moisturizer."
