Acne

What Is Acne?

There's a reason it's called "common acne" -- nearly everyone suffers from outbreaks of pimples at some point in life.
It starts when greasy secretions from the skin's sebaceous glands plug the tiny openings for hair follicles (plugged pores). If the openings are large, the clogs take the form of blackheads: small, flat spots with centers darkened by exposure to air. If the openings stay small, the clogs take the form of whiteheads: small, closed, flesh-colored bumps. Both types of plugged pores can develop into swollen, tender inflammations or pimples or deeper lumps or nodules. Cysts associated with severe cases of acne (cystic acne) are firm swellings below the skin's surface that become inflamed and sometimes infected.

What Causes Acne?

The cause of acne is not fully understood. Though stress can aggravate acne, it clearly does not cause it.

Hormones. Common acne in teenagers starts with an increase in hormone production. During puberty, both boys and girls produce high levels of androgens, the male sex hormones that include testosterone. Testosterone signals the body to make more sebum, a waxy substance that helps the skin retain moisture.

Bacteria. Excess sebum clogs the openings to hair follicles -- especially those on the face, neck, chest, and back. Bacteria grow in these clogged follicles. This makes blackheads or whiteheads form on the skin's surface -- a condition called non-inflammatory acne. Sometimes the follicle wall breaks under the pressure of this buildup. When this happens, sebum leaks into nearby tissues and forms a pustule -- this is called inflammatory acne. This can create cysts. Ruptured cysts can leave temporary or permanent scars.
