Dermatologists are medical doctors who specialise 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 specialise in treating specific age groups, such as a paediatric dermatologist, who only treats children.
