I struggled with cystic acne from the ages of 17 to 23. My acne was not severe but persistent.
I tried every treatment known to man: over the counter products, Proactiv, prescription Benzoyl Peroxide, Retin-A Micro, chemical peels, vibradermabrasion, Smoothbeam laser, etc. Although combination therapy with Retin-A Micro, chemical peels, and vibradermabrasion helped control my breakouts, I never completely got rid of acne until I decided to go on Accutane.
I was prescribed 40mg of Accutane a day for 5 months. For the first 6 weeks, I broke out a little more than usual, nothing drastic. Ever since, my skin has been completely clear of cystic acne. I've been off the medication for 4 months now and am elated with the results!!
I experienced little to no side effects during treatment. Don't listen to all the skeptics out on the internet; they're completely full of it and not doctors. Your physician/dermatologist wouldn't prescribe the medication if they believed it caused harmful side effects.
Bottom line, if you want to get rid of acne, take Accutane!! It's fantastic.
