Dermatologists are medical doctors who specialize in diagnosing and treating diseases and conditions of the skin, hair, or nails, such as acne, psoriasis, warts, or skin cancer.

Dermatologists may prescribe medicines as well as perform surgery for skin disorders. They may specialize in treating specific age groups, such as a pediatric dermatologist, who only treats children.

Dermatologists are certified by the Royal College of Physicians and Surgeons of Canada.
