After earning a bachelor's degree, a medical degree from an accredited medical school must be earned in order to be a dermatologist. A Doctor of Osteopathic Medicine (D.O.) degree, a Doctor of Medicine (M.D.) degree, or a Bachelor of Medicine/Bachelor of Surgery (MBBS/MBChB) degree may be earned to meet this requirement. After earning one of these recognized medical degrees, a residency in dermatology must be completed and board certification examinations must be successfully passed.
