Dermatology is the branch of medicine that focuses on the health of the skin, hair, and nails. It involves diagnosing, treating, and preventing a wide range of conditions, from common issues like acne, eczema, and fungal infections to more complex concerns such as autoimmune skin disorders and skin cancers.

Dermatologists are medical doctors trained to recognize how changes in the skin may also reflect overall health, since skin conditions can sometimes be linked to internal diseases. Alongside medical treatments, dermatology also includes cosmetic care—improving appearance and confidence through procedures like laser therapy, chemical peels, or injectables.

In essence, dermatology blends medical science with preventive and aesthetic care, ensuring patients maintain healthy, functional, and vibrant skin, hair, and nails throughout their lives.
