There are several different types of doctors who can treat acne. Often, the kind of doctor needed to treat a case of acne depends on the severity and cause of acne. With that in mind, the types of doctors who can provide acne treatment include dermatologists, obstetrician-gynecologists (OB/GYNs), or primary care providers, like a family medicine physician, internal medicine doctor, or a pediatrician. For severe cases of acne, your primary care provider will likely refer you to a board-certified dermatologist. Some signs that your acne requires the specialty of a dermatologist include: - It feels like you have tried everything with no success at clearing up acne - Frequent acne breakouts, even after previous breakouts clear up - Pimple-like bumps appear in unusual areas, such as the armpit, groin, thighs, or the back of your upper arm - Deep acne cysts and nodules that cause you pain - Have had acne for years without knowing why - Acne on your back or chest that will not clear up no matter what you try For less severe cases of acne, your primary care provider can usually provide sufficient treatment. If your primary care provider specializes in acne treatment, there is a good chance they will be able to treat moderate to severe cases of acne effectively. In cases where the acne is caused by hormonal imbalances or changes associated with pregnancy, menstrual cycles, or puberty, an OB/GYN may also be a good choice.
