What is a dermatologist?
A dermatologist is a doctor who specializes in the diagnosis and treatment of health conditions of the hair, nails, and skin. They can diagnose and treat more than 3,000 diseases of the skin, hair, and nails, as well as cosmetic concerns.
They are experts in skincare and have extensive knowledge and training in the management of cosmetic disorders of the skin (such as acne, warts, hair loss, birthmarks, and scars). They often deal with conditions that are more than just skin deep and may be associated with many diseases of the blood, organs, and organ systems.
Dermatologists may often perform specialized procedures for the diagnosis of conditions related to the skin. They may provide treatments such as:
- Topical (externally applied), injected, and oral medicines
- Ultraviolet (UV) light therapy

Dermatologists may have training and experience in areas such as:
- Electrosurgery (surgical use of high-frequency electric current for cutting or destroying tissue)
- Cryosurgery (it involves freezing tissue to treat conditions)
- Laser surgery
- Excision surgery (involving removal by cutting) with appropriate closures (including skin grafts)
