Benzoyl peroxide / clindamycin
"Just want to start by stating my skin type..I get bad breakouts & that's  why I am on Duac. I'd say I have "normal"skin as it doesn't tend to be dry or oily. I would describe my acne as not extremely severe, it can flare up pretty bad & when it's at it's worst, it can sometimes actually hurt *To the point* I'm on this product a few months now.  After about a month or so I THOUGHT it was working, but my breakouts are still happening just as bad, it does not prevent them at all!! Now, I've a bad breakout for the past week & a half and it hasn't helped all that much. I use Duac at night time because I find that's what suits me best..I have a strict night time routine..I cleanse, moisturise and then apply my Duac. It flakes so bad!! Will be discontinuing."
