Accutane, or isotretinoin, is a potent oral medication used to treat severe acne that has not responded to other treatments. It works by significantly reducing oil production in the skin, preventing clogged pores. While highly effective, Accutane can have serious side effects, including dry skin, chapped lips, increased liver enzymes, and severe birth defects if taken during pregnancy. Regular blood tests and medical supervision are essential during treatment. Despite the potential risks, many patients achieve long-term or permanent clearance of acne, making Accutane a valuable option for those with severe or persistent acne issues.
