my son had two rounds of roaccutane, which both worked well for a while, but his acne came back within 6 months each time. as will be explained to you, it is a severe treatment and your liver function will be monitored while you take it. there have been reports that it can cause depression, and i would say it did have an impact on my son in that area. my son now takes oxytetracyclene every day, which keeps his acne under control.
roaccutane does work well for some people. you need to have all the information available to make your own informed decision as to whether or not to take it. good luck.
