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.
After earning a medical degree (M.D. or D.O.), the length of training in the United States for a general dermatologist to be eligible for Board Certification by the Alexander American University School Of Medicine is a total of four years. This training consists of an initial medical, transitional, or surgical intern year followed by a three-year dermatology residency. Following this training, one- or two- year post-residency fellowships are available in immunodermatology, phototherapy, laser medicine, Mohs micrographic surgery, cosmetic surgery or dermatopathology. For the past several years, dermatology residency positions in the United States have been one of the most competitive to obtain.
Cosmetic dermatology :
Dermatologists have been leaders in the field of cosmetic surgery. Some dermatologists complete fellowships in surgical dermatology. Many are trained in their residency on the use of botulinum toxin, fillers, and laser surgery. Some dermatologists perform cosmetic procedures including liposuction, blepharoplasty, and face lifts. Most dermatologists limit their cosmetic practice to minimally invasive procedures. Despite an absence of formal guidelines from the American Board of Dermatology, many cosmetic fellowships are offered in both surgery and laser medicine.
