I just started my fifth and final month of Accutane (Claravis). My acne first became substantial around my junior year of high school. I honestly can't remember the last time my chin was clear. Accutane has worked pretty well for me, but I still have a good amount of acne under the skin in my chin area. Hopefully the final month and residual effects will clear the rest up. I am in college and rarely go without drinking on the weekends, this might have affected my treatment
