Adapalene / benzoyl peroxide
"Wait it out! I'm a 32 yr old female that began suffering from adult cystic acne just over a year ago. For some reason, only the right side of my face really broke out and the acne was deep and painful. After using Epiduo for the recommended 3 months, I wasn't seeing results. The itchiness and peeling stopped after only two weeks of using it so I thought the product wasn't even working for me at the 3 month mark. I stuck with it anyway and now at 4 months, I have no more active acne and my skin is baby smooth! The down side to this med is that it caused post inflammatory hyperpigmentation which takes time to fade. But I'm happy that until then, my feels good and there's no more acne!"
