When should someone with acne see a doctor? If your acne doesn't respond to OTC medications, if you have severe acne, or if it's affecting you emotionally or psychologically, you probably should visit your doctor. Also, if you're already taking prescription medicine and you think it's causing or aggravating your acne. Your family doctor is probably the first person you should see, and he or she can refer you to a specialist if needed.
