Osmosis video - Acne vulgaris

Acne vulgaris (commonly called acne) is a chronic skin disease that occurs when hair follicles are clogged with dead skin cells and oil from the skin. It is characterized by blackheads or whiteheads, pimples, oily skin, and possible scarring.

It primarily affects areas of the skin with a high number of oil glands, such as the face, chest, shoulders, and back. Acne is self-limiting but can cause significant emotional distress.
