The skin is the largest organ of the body and is the most visible. Although many skin diseases are isolated, some are manifestations of internal disease. Therefore, a demonologist has knowledge of all aspects of surgery, rheumatology (many rheumatic diseases can feature skin symptoms and signs), immunology, neurology (the "neurocuteaneous syndromes", such as neurofibromatosis and tuberous sclerosis), infectious diseases and endocrinology. Cosmetic dermatology has long been an important part of the field, and dermatologists have been the primary innovators in this area. In the 1900s, dermatologists used dermabrasion to improve acne scarring. Doctors used fat micro-transfer to fill in cutaneous defects. Dermatologists specializing in cosmetic dermatology typically use non-invasive procedures to reverse the signs of aging. Botox has been popular since the Food and Drug Administration approved it for the treatment of wrinkles. Botox minimizes wrinkles such as frown lines and crow's feet. Fillers are used to "fill in" lines on the face and to minimize the appearance of wrinkles. Brand name fillers include Restylane, Perlane, Juvederm, Radiesse and Cosmoplast among many others. Dermatologists are also the pioneers of energy-based treatments for the skin and these include lasers, intense pulsed light, radiofrequency, infrared light and photodynamic treatments.

Retinoids Topical Acne Treatment

Retinoids are a group of medications that normalize the follicle cell lifecycle. There are topical retinoids such as tretinoin (brand name Retin-A), adapalene (brand name Differin) and tazarotene (brand name Tazorac). Like isotretinoin, these medications are similar to vitamin A, but they are topical treatments and generally have much milder side effects. However, they can cause significant irritation of the skin. The retinoids appear to influence the creation and death lifecycle of cells in the follicle lining. This helps prevent the hyper-keratinization of these cells that can create a blockage. Retinol, a form of vitamin A, has similar but milder effects and doctors prescribe because it also contains moisturizers. Doctors have prescribed topical retinoids for over 30 years, but are not available over the counter, so they are not as widely used as other topical treatments. Topical retinoids often cause an initial flare up of acne and facial flushing.
