OVERVIEW

What Is Dermatology?

Dermatology is the branch of medicine focused on the skin, hair, and nails, covering conditions ranging from eczema, psoriasis, and acne to various forms of skin cancer. Care in this branch also includes cosmetic dermatology, such as laser treatments and injectables, for patients seeking non-surgical improvements in skin appearance.

Some skin conditions treated in this branch are caused by viral infections, such as warts linked to the human papillomavirus (HPV) or cold sores caused by the herpes simplex virus. Patients are seen here both for persistent or unexplained skin changes, such as unusual moles, rashes, or hair loss, and for the ongoing management of a diagnosed skin condition. When a concern requires surgical correction rather than medical or cosmetic treatment, care is coordinated with Aesthetic and Reconstructive Surgery.

Diagnosis often starts with a visual examination of the skin, and a biopsy may be taken when a growth or lesion needs closer evaluation, particularly to rule out skin cancer. Sun exposure is one of the most significant, and most preventable, risk factors for skin damage and skin cancer, which is why routine skin checks and sun protection are commonly recommended as part of long-term skin health.
