A dermatologist is a medical professional who specializes in diagnosing and treating skin issues, including diseases and infections and also conditions such as acne, psoriasis, and eczema. Dermatologists work to diagnose and treat skin issues, so they can be considered to be the physicians of the skin. They perform a range of treatments, including surgical procedures, injections, and laser therapy, and they also advise patients on skin care and sun protection. People often enjoy being a dermatologist because it allows them to make a positive difference in their patients' lives by providing them with the best possible care and giving them the confidence to enjoy their skin.
