The skin is both barrier and billboard for internal disease. Dermatology is the medical specialty devoted to the diagnosis and treatment of conditions affecting the skin, hair, nails, and mucous membranes.

Dermatologists manage acne, eczema, psoriasis, infections, autoimmune blistering diseases, and skin cancers. They perform visual diagnosis, skin biopsies, surgical excisions, and a range of medical and light-based therapies. Cosmetic and laser procedures form an additional part of many practices.

Because skin findings often reflect systemic illness, dermatologists collaborate frequently with other specialists. Early detection of melanoma and other skin cancers saves lives. Patient education on sun protection and self-examination is a routine element of care.
