acne
"Epiduo is worth it. It was 3 months of flaking, burning, and more irritated acne than before, but after the worst months in my skin's history, I woke up one morning and my face was just better. I used to have my entire jawline covered in painful cystic acne, but now I wake up to maybe a pimple or 2 at most. I promise that if you don't give up, it will pay off. This is one happy customer. 

If your skin ever gets too irritated, stop using Epiduo for a few days. Taking Epiduo every 3 days is always better than giving up.

(Also, it cost $85 out of pocket but I've been using the same bottle for 4 months.)"
