What is Dermatology and What Dermatologists Do - The skin is the largest organ in the body that functions as a protector to protect internal organs from bacteria and injury. Skin health can be a visible indicator of overall body health. This makes the field of dermatology important in the diagnosis and management of many health conditions.

Dermatology Overview

Dermatology involves the study, research, diagnosis and management of any health condition that can affect the skin, hair and nails. The root word for dermatology itself is 'derm' or 'dermis' which comes from the Greek word meaning 'skin'.

A doctor who specializes in this field of health care is called a dermatologist. General practitioners and internal medicine doctors may be able to diagnose and treat certain skin conditions. However, a dermatologist has better understanding, experience, and expertise than a general practitioner when it comes to skin, hair or nail care.


Some chronic skin problems that require a dermatologist's attention include acne, psoriasis, rosacea, and eczema. In addition, dermatologists are also able to treat a number of acute skin problems including hair loss, ingrown hair, dermatitis, warts, itching, skin cancer, and others.
