What's the most effective way to treat acne?

Depends...: ...On many factors. Each individual responds differently to different treatments, so there is no one "most effective" treatment. That's why one-size-fits-all regimens like proactive work well for some people and horribly for others. A dermatologist can tailor an individual treatment based on your skin type and the variety of acne you have. That, for you, will be the most effective.

Accutane: Acne is a disease of the hair follicle unit, often begins at puperty when male and female hormones stimulate the production of skin oil, sebum. Early lesions, age 11-16, are tiny bumps, black heads and white heads. Older kids often get large tender bumps, acne cysts. Many meds help acne, topicals and pills, but only Accutane can stop acne forever. You need to see a dermatologist for this drug.

And psychiatrist: Dr feinstein is quite correct in stating that Accutane stops acne best. But it has many significant side effects. You should have a mental health screening before using accutane. The most dangerous side effect is suicide.
