Nothing seems to work on my acne. Any Suggestions?

Cosmetic/Dermatological treatment...chemical peels, microdermabrasion, even more excessive treatments...Ask your dermatologist one last time for his/her last piece of advice. Someone at your age should not keep dealing with acne like a teenager. Go for the cosmetic/surgical treatment if it comes down to it. It may be expensive, but at least the acne will be scd off.
