Dermatology is the study of skin diseases and conditions. A dermatologist treats disorders relating to the skin, hair, and nails. A dermatologist is a physician who has completed medical school, at least one year of  postdoctoral training and three or more years of intensive residency training in dermatology. After medical school, internship, and residency, a dermatologist is eligible to take the board certification examination offered by the American Board of Dermatology.
