About acne

Acne (acne vulgaris) is one of the most common skin conditions in the world: up to 650 million people suffer from this condition, and almost anyone can be affected.

Acne causes spots, known as lesions, to appear on different parts of the body, though commonly on the face. Acne usually develops when people reach puberty and skin glands become plugged with increasing amounts of sebum (a naturally-occurring substance, which normally helps to protect the skin) and dead skin cells. This combined with acne-associated strains of C. acnes, a skin bacterium, may cause inflammation of the gland leading to the development of acne lesions.

Up to 85% of 12–24 years olds experience acne. However, hormone changes and stress can also trigger acne in adults.

Acne can be mild, moderate or severe, and waiting for acne to clear up on its own can be frustrating. The longer acne is present, the higher the likelihood is of acne scars developing.
