Dermatologists are specialist physicians who diagnose and treat diseases of the skin, hair and nails. The dermatologist role has both medical and surgical aspects and offers opportunities to practice subspecialist fields of dermatology including aesthetic dermatology (cosmetic dermatology), paediatric dermatology, dermatopathology, immunodermatology and Mohs surgery for dermatological tumour excision.

Dermatologists must complete residency or specialist training in dermatology and obtain a board or specialist certification in dermatology.
