Acne

Acne is a common skin disease characterized by pimples that form when hair follicles under the skin become clogged.

Overview

Acne is a common skin disease that causes pimples. While it is not serious, it can lead to scarring. Pimples most frequently form on the face, neck, back, chest, and shoulders. Although anyone can develop acne, it is particularly common in teenagers and young adults.

Causes and Myths

The exact cause of acne is unknown, though hormone changes—such as those occurring during the teenage years and pregnancy—likely play a role. Several common myths exist regarding acne:

• Diet: Chocolate and greasy foods are often blamed, but there is little evidence that food significantly affects acne for most people.
• Hygiene: Blackheads and pimples are not caused by dirt.
• Stress: Stress does not cause acne, though it can make existing acne worse.

Management

If you have acne, consider the following steps:

• Clean your skin gently.
• Try not to touch your skin.
• Avoid the sun.

Treatments for acne include various medicines and creams.
