Dermatology refers to the branch of medicine which deals with the skin, its conditions, as well as other related parts including the sweat glands and hair. There are various branches under dermatology, such as cosmetic dermatology and immunodermatology. Cosmetic dermatology involves optional procedures, while immunodermatology focuses on skin conditions that results from problems with the immune system. People normally visit the dermatologist for skin conditions which require medical attention, such as pre-cancerous moles.
For a person to become a dermatologist, he/she must undergo four years of medical schooling, in order to learn about physiology, anatomy, and other basics that are needed for the practice of medicine. After taking formal education at a medical school, the person must attend a medical residency in the field of dermatology. If the person wants to have a sub-specialty, such as pediatric dermatology, he may also opt to attend an additional residency.
People who specialize in this medical field will be able to investigate on the skin problem, identify the causes, and provide treatment options. For instance, a dermatologist may prescribe medications, advise on the use of creams, or recommend changes in diet, in order to address dry skin problems. For moles which look suspicious, a biopsy may be conducted by the dermatologist in order to determine if it is cancerous or not. If the mole is proven to be cancerous, it will be removed by the specialist.
Because the skin is a visible organ and many people are interested to enhance their physical appearance, it can be considered as very profitable to practice in the field of cosmetic dermatology. Dermatologists who practice in this area may perform different procedures, such as Botox and liposuction, in order to help clients achieve their desired look. Additionally, dermatologists can also help those with port-wine stain and other forms of disfigurement, to look normal.
