acne (s) (noun), acnes (pl)
1. An ailment of the oil-secreting glands of the skin which often affects adolescents: Acne is characterized by prducing red pimples or eruptions on the face, neck, and shoulders that can leave pitted scars.
2. Localized skin inflammation as a result of over activity of the oil glands at the base of hair follicles: Acne appears when oil (sebaceous) glands come to life around puberty when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls.

The oil glands, which are located just beneath the skin, continuously produce and secrete oil through openings in the skin. The oil lubricates and protects the skin.

Under certain circumstances, cells that are close to the openings of the oil glands block the openings. This causes a buildup of oil underneath the skin.

Certain bacteria feast on this oil, multiply, and cause the surrounding tissues to become inflamed.

If the inflammation is near the surface, a person will get a pustule. If it's deeper, it is called a papule (pimple). And if still deeper, it is termed a cyst.

If the oil breaks though to the surface, the result is a "whitehead". If the oil becomes oxidized (that is, acted on by oxygen in the air), the oil changes from white to black, and the result is a "blackhead".

The Barnhart Dictionary of Etymology states that acne was borrowed from Late Greek, akne, in 1835, as a New Latin medical term. It was misspelled by the 6th century author, Aëtius, of the Greek "akme", (highest) point.

Klein's Comprehensive Etymological Dictionary of the English Language says, "this word owes its existence to a clerical error of Greek, akme, 'point', having been miswritten as akne."

A chronic skin disease which causes redness over parts of the face, such as the cheeks and nose, but primarily the forehead, the chin, and the lower half of the nose: With rosacea, the tiny blood vessels in the areas of the face enlarge (dilate) and become more visible through the skin, characterized by red or rosy colorations like tiny red lines or the appearance of acnelike pimples.

Increased conditions of acne rosacea can be prevented by avoiding certain foods, alcohol, caffeine, and exposure to sunlight, extremes of temperature, wind, and certain cosmetics as prescribed by a dermatologist.

In the earlier stages of rosacea, the patient may notice gradual reddening of the skin, often mistaking these changes for acne, sunburn, or dermatitis.
