Also known as a skin doctor, a dermatologist specializes in the care of the body's largest organ. Dermatologists diagnose and treat more than 3,000 conditions. They are also referred to as hair and skin doctors because they also help care for patients who experience problems with their hair and nails.

The most obvious difference between medical and cosmetic dermatology is that one deals with illness while the other does not. Consequently, the cases treated by the first, but not the second, are time-sensitive.

A dermatologist is a medical doctor who specializes in conditions that affect the skin, hair, and nails.

Your GP may refer you to a registered consultant dermatologist if they believe your condition needs further investigation, or you can book directly with a registered private consultant if you'd prefer to pay privately or have medical insurance (please check with your insurance provider).
