Acne usually improves around the age of 20 but may persist into adulthood. Permanent physical scarring may occur. There is good evidence to support the idea that acne and associated scarring negatively affect a person's psychological state, worsen mood, lower self-esteem, and are associated with a higher risk of anxiety disorders, depression, and suicidal thoughts. Another psychological complication of acne vulgaris is acne excoriée, which occurs when a person persistently picks and scratches pimples, irrespective of the severity of their acne. This can lead to significant scarring, changes in the affected person's skin pigmentation, and a cyclic worsening of the affected person's anxiety about their appearance. Rare complications from acne or its treatment include the formation of pyogenic granulomas, osteoma cutis, and acne with facial edema. Early and aggressive treatment of acne is advocated by some in the medical community to reduce the chances of these poor outcomes.
