I have suffered with acne for years. I'm currently 22 and have horrible cystic acne along my jawline. The rest of my face is clear, however I do have some acne scarring on my cheeks. Last year I went to a dermatologist who prescribed me Epiduo and Minocycline 100 mg (2x a day) in the morning and Ziana at night. I used this regimen for months, but felt that there was barely an improvement in my skin and my skin was horribly irritated so I stopped using all of the medication. Recently my acne has gotten worse so I tried using Benzoyl Peroxide for a few weeks with no improvement. I have RetinA (tretinoin) 0.05% cream currently and Epiduo and was wondering if it was okay to use both of those creams together. I plan on using the RetinA at night and the Epiduo in the morning. Anyone who could offer me some experiences with these medications would be very helpful!
