Acne did not improve after Epiduo after 6 months. What now? (photos)

I did 2courses of accutane (when I was 20, then 23) after trying every prescription pill in the market and now my skin is staring to relapse once again. My GP prescribed Epiduo before giving a referral to the Derm just to see if it works but apparently my skin looked worse. Dried flaky skin with more spots than before. I just dont know what to do anymore.
