Dermatology after medicine

After earning a Doctor of Medicine (MD) degree, graduates must then do a residency, which is required to become a licensed physician. Future dermatologists must do a preliminary transitional year in a broad-based clinical specialty (usually internal medicine) before completing a three-year residency in dermatology.

How long does it take to become a dermatologist?

Dermatologists are physicians trained in the medical, surgical, and cosmetic care of the skin.
To become a dermatologist, physicians must spend an additional year of internship in general medicine, and then another three years training in the specialty of dermatology after they complete medical school.
