Which medical professional focuses on diagnosing and treating diseases of the skin?

The correct answer is a dermatologist, as this medical professional specializes in diagnosing and treating conditions affecting the skin, hair, and nails. Dermatologists are trained to manage a wide range of skin disorders, including acne, eczema, psoriasis, and skin cancers, among others. Their expertise allows them to perform various procedures such as skin biopsies, laser therapy, and cosmetic enhancements aimed at improving skin health.

In contrast, an endocrinologist primarily focuses on hormonal disorders and the glands responsible for hormone production, not specifically skin diseases. A family physician provides comprehensive healthcare for individuals and families, but their scope includes a broad range of general health issues rather than concentrating solely on dermatological concerns. An emergency physician deals with urgent and life-threatening conditions, which may occasionally include skin emergencies, but they do not specialize in skin-related diseases as part of their primary focus. Therefore, a dermatologist is distinctly qualified for the diagnosis and treatment of skin-related ailments.
