Dermatology is the branch of medicine dealing with the skin.[1][2] It is a speciality with both medical and surgical aspects.[3][4][5] A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems.[2][6]


Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (dermatos), genitive of δέρμα (derma), "skin"[7] (itself from δέρω dero, "to flay"[8]) and -λογία -logia. Neo-Latin dermatologia was coined in 1630, an anatomical term with various French and German uses attested from the 1730s.[9]


Main article: History of dermatology

In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases (Alibert's, 1806–1816) appeared in print around the same time.[10]

United States

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 American Academy of Dermatology, American Board of Dermatology, or American Osteopathic Board of Dermatology is four years.[11] This training consists of an initial medical, transitional, surgical, or pediatric intern year followed by a three-year dermatology residency.[2][12][13] Following this training, one- or two-year post-residency fellowships are available in immunodermatology, phototherapy, laser medicine, Mohs micrographic surgery, cosmetic surgery, dermatopathology, or pediatric dermatology. While these dermatology fellowships offer additional subspecialty training, many dermatologists proficiently provide these services without subspecialty fellowship training. For the past several years, dermatology residency positions in the United States have been one of the most competitive to obtain.[14][15][16]

According to the American Academy of Dermatology, dermatologists are trained to diagnose and manage over 3,000 distinct skin, hair, and nail conditions across patients spanning various age groups.[17]

The United States has been experiencing a national shortage of dermatologists for more than a decade. A study published by the Journal of the American Medical Association reported fewer than 3.4 dermatologists for every 100,000 people.[18]

United Kingdom

In the UK, a dermatologist is a medically qualified practitioner who has gone on to specialize in medicine and then subspecialize in dermatology. This involves:

Upon successful completion of the four-year training period, the doctor becomes an accredited dermatologist and is able to apply for a consultant hospital post as a consultant dermatologist.[19]


Cosmetic dermatology

Dermatologists have been leaders in the field of cosmetic surgery.[20] 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.[21][22] 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.[23]


Main article: Dermatopathology

A dermatopathologist is a pathologist or dermatologist who specializes in the pathology of the skin.[24] This field is shared by dermatologists and pathologists. Usually, a dermatologist or pathologist completes one year of dermatopathology fellowship. In 2022, the market size was valued at a substantial $0.6 billion,[25] and according to market projections, it is estimated to expand at a compound annual growth rate (CAGR) of 11.4% from 2022 to 2030. This usually includes six months of general pathology and six months of dermatopathology.[26] Alumni of both specialties can qualify as dermatopathologists. At the completion of a standard residency in dermatology, many dermatologists are also competent at dermatopathology. Some dermatopathologists qualify to sit for their examinations by completing a residency in dermatology and one in pathology.[citation needed]


Main article: Trichology

Trichology specializes in diseases, which manifest with hair loss, hair abnormalities, hypertrichosis and scalp changes. Trichoscopy is a medical diagnostic method that is used by dermatologists with a special interest in trichology.[27]


Main article: Immunodermatology

This field specializes in the treatment of immune-mediated skin diseases such as lupus, bullous pemphigoid, pemphigus vulgaris, and other immune-mediated skin disorders.[28] Specialists in this field often run their own immunopathology labs.[citation needed] Immunodermatology testing is essential for the correct diagnosis and treatment of many diseases affecting epithelial organs including skin, mucous membranes, gastrointestinal and respiratory tracts. The various diseases often overlap in clinical and histological presentation and, although the diseases themselves are not common, may present with features of common skin disorders such as urticaria, eczema and chronic itch. Therefore, the diagnosis of an immunodermatological disease is often delayed. Tests are performed on blood and tissues that are sent to various laboratories from medical facilities and referring physicians across the United States.[29]

Mohs surgery

Main article: Mohs surgery

The dermatologic subspecialty called Mohs surgery focuses on the excision of skin cancers using a technique that allows intraoperative assessment of most of the peripheral and deep tumor margins. Developed in the 1930s by Frederic E. Mohs, the procedure is defined as a type of CCPDMA processing. Physicians trained in this technique must be comfortable with both pathology and surgery, and dermatologists receive extensive training in both during their residency. Physicians who perform Mohs surgery can receive training in this specialized technique during their dermatology residency, but many seek additional training either through formal preceptorships to become fellows of the American Society for Mohs Surgery[30] or through one-year Mohs surgery fellowship training programs administered by the American College of Mohs Surgery.[31] In 2020, the American Board of Dermatology (ABD) received approval from the American Board of Medical Specialties (ABMS) to establish a board-certification exam in the subspecialty of Micrographic Dermatologic Surgery (Mohs Surgery). The exam was first offered in October 2021 to any US board-certified dermatologist who practices Mohs surgery, regardless of whether they received their training in dermatology residency or as part of a fellowship.[32]

This technique requires the integration of the same doctor in two different capacities - surgeon and pathologist. In case either of the two responsibilities is assigned to another doctor or qualified health-care professional, it is not considered to be Mohs surgery.[citation needed]

Pediatric dermatology

Physicians can qualify for this specialization by completing both a pediatric residency and a dermatology residency. Or they might elect to complete a post-residency fellowship.[33] This field encompasses the complex diseases of the neonates, hereditary skin diseases or genodermatoses, and the many difficulties of working with the pediatric population.[34]


Main article: Teledermatology

Teledermatology is a form of dermatological practice in which telecommunication technologies are used to exchange medical information and treatment through audio, visual, and data communication, including photos of dermatologic conditions, between dermatologists and nondermatologists who are evaluating patients, along with dermatologists directly with patients via distance.[35][36][37] In India, during the severe coronavirus situations, some dermatologists have initiated online consultation with their patients using some of popular apps, such as Practo, Apollo Pharmacy, Skin Beauty Pal, Lybrate, etc. This subspecialty deals with options to view skin conditions over a large distance to provide knowledge exchange,[38] to establish second-opinion services for experts,[39] or to use this for follow-up of individuals with chronic skin conditions.[40][41] Teledermatology can reduce wait times by allowing dermatologists to treat minor conditions online while serious conditions requiring immediate care are given priority for appointments.[42]


Dermatoepidemiology is the study of skin disease at the population level.[43] One of its aspects is the determination of the global burden of skin diseases.[44][45] From 1990 to 2013, skin disease constituted about 2% of total global disease disability [46] as measured in disability-adjusted life-years.[47]

Most dermatologic pharmacology can be categorized based on the Anatomical Therapeutic Chemical (ATC) classification system, specifically the ATC code D.
