Accutane worked for my cystic acne, too. I had been through EVERY treatment before and thought nothing was going to work but after 2 rounds I haven't had a breakout in 5 years and get compliments daily on my complexion.

Where I live it is also really dry and Bare Minerals made my skin flake, too. I started doing at-home facial peels and using a heavier, creamier moisturizer in a jar rather than a liquid, pump-y one and it worked for me.
