Dermatology is the branch of medicine dealing with the skin, nails, hair and its diseases. It is a specialty with both medical and surgical aspects. A dermatologist treats diseases, in the widest sense, and some cosmetic problems of the skin, scalp, hair, and nails.Dermatologists have been leaders in the field of cosmetic surgery. Many dermatologists trained in their residency on the use of botulinum toxin, fillers, and laser surgery.
