Dermatologists are specialists who treat disorders of the skin. But they do not just treat skin problems: they treat the health problems of hair and nails. They are full-fledged physicians trained to diagnose and treat diseases and disorders of the skin, hair and nails. The most common skin condition that dermatologists treat is acne. Acne is a skin disease that almost all people face at some point during their teenage years. Acne cases range from mild (the occasional pimple or zit) all the way to very severe (which consists of deep lesions of acne and scars often spread). Acne is caused by the overproduction of oil from the hair follicles of the sebaceous glands, which combines with dead cells to clog pores. This can lead to whiteheads, blackheads, pustules and papules, or in the most severe cases, cysts. Most cases of acne do not require the services of a dermatologist, such as a healthy and nonprescription skin care regime. But for these persistent, moderate to severe cases, a dermatologist is almost always necessary. These doctors can prescribe more potent topical medications as well as oral antibiotics, to help control difficult cases.
They can also provide the medical means by which acne scars are reduced or eliminated.Dermatologists also diagnose and treat other skin disorders such as as skin cancer. Physicians will examine suspected sites of skin cancer on the body and, if necessary, perform a biopsy to check for cancer. There are a variety of types of skin cancer of varying degrees of severity. Needless to say, a doctor should immediately examine anyone who suspects that he may have some form of skin cancer. Psoriasis is another skin condition treated by these doctors. It is a chronic red rash, sometimes accompanied by itching, that affects a relatively large segment of the population. It can vary in severity barely noticeable, needing hospitalization. Aside from the rash, a person may experience some degree of pain in various joints – which can be debilitating. The immune system is thought to be involved in psoriasis, although this is not certain. There seems to be a genetic predisposition to this disease. Although there is no cure, there are effective treatments that a dermatologist can provide after the diagnosis.
Dermatologists also treat warts. These tumors resembling rough tumors can appear anywhere (but usually on the hands and feet) and are caused by viruses. Some warts go away on their own but others can persist for many years. Dermatologists treat warts in different ways. One option is to wait and see if it disappears on its own. And they can use salicylic acid in liquid form or in a patch. Often this will gradually make the wart disappear. They can also freeze it, gently, over a period of time. A dermatologist can also use surgery, lasers and chemical cautery to get rid of them. Dermatologists also treat patients to remove their scars. They can use lasers of different types to reduce, or even to completely get rid of these scars. The types that can be treated are those that result from wounds, acne scars, keloids and hypertrophic scars. With modern lasers today, scars can be reduced to a degree that could never in the past. These are just a few of the many conditions that dermatologists can treat. Dermatology is an area of many specialties and areas of expertise, and it is the state of the art in medicine.
