How often should I see a dermatologist?

You should see a dermatologist if you believe you have a disease of the skin, hair, or nails, or if you find any unusual or suspicious-looking moles, marks or spots on your skin. You should also see a dermatologist if you have risk factors for skin cancer, such as a family history of the disease or 50 or more moles on your skin.

A dermatologist is a medical doctor who is trained to diagnose and treat skin diseases and related disorders. If your primary-care physician thinks you need to be treated by a dermatologist, he or she will make a referral for you to see one. Your dermatologist may advise you to return for regular office visits. 

It's recommended that even healthy adults have an exam performed by a dermatologist once per year.
