"i love duac! it completely helped clear up my acne last year alone! this was my most favourite acne treating product along side quinoderm 10% which i can no longer get anywhere!! i rate duac a 7/8 out of 10 as it was great but wasn&#039;t as good as quinoderm 10%. i still use duac every night before i go to bed. i do still have some spots /scars but comparing my face this year to how bad it was last year wow big change and i believe duac has improved my skin so much. sometimes makes my skin dry,red and sore but that&#039;s only if i apply too much. it&#039;s keeping my skin under control and i&#039;m happy with that. i don&#039;t usually store duac in the fridge. i&#039;m hoping that eventually the spot phase been going all through my teen years will just disappear."
