Types of ACNE

According to wikipedia, there are many types of acne, and they are as follows:

• Acne vulgaris - most commonly experienced around puberty, typically of the face and shoulders/chest
• Acne rosacea - a red rash predominantly on the face
• Acne keloidalis nuchae (Pseudofolliculitis nuchae) - a rash caused by shaving
• Acne conglobata (Hidradenitis suppurativa) - chronic abscesses or boils of sweat glands and hair follicles; in the underarms, groin and buttocks, and under the breasts in women
• Acne cosmetica - acne caused by cosmetics
• Acne fulminans - an extreme form of acne conglobata
• Acne medicamentosa - acne caused by starting or stopping a medicine • Baby acne - a rash seen on the cheeks, chin, and forehead of infants
• Chloracne - an acne rash caused by exposure to chlorinated hydrocarbons such as dioxins or PCBs

Acne is caused by the clogging of pores and the inflammation of the sebaceous glands and hair follicles. It can occur on the face, neck, shoulders, back and chest. This happens because the glands produce oil and when the pores are clogged it becomes whiteheads or blackheads. And when bacteria infect the hair follicles, and when the whitehead raptures, a pimple is produced. And if pimples are squeezed, scars on the face can develop.


Acne can take the following forms:

- Comedones (whiteheads and blackheads). Comedones (kom-uh-DO-neze) are created when the openings of hair follicles become clogged and blocked with oil secretions, dead skin cells and sometimes bacteria. When comedones are open at the skin surface they're called blackheads because of the dark appearance of the plugs in the hair follicles. When comedones are closed, they're called whiteheads — slightly raised, skin-colored bumps.

- Papules. These are small raised bumps that signal inflammation or infection in the hair follicles. Papules may be red and tender.
- Pustules. Similar to papules, pustules are red, tender bumps with white pus at their tips.
- Nodules. These are large, solid, painful lumps beneath the surface of the skin. They're formed by the buildup of secretions deep within hair follicles.
- Cysts. These are painful, pus-filled lumps beneath the surface of the skin. These boil-like infections can cause scars. Common Causes of Acne :
- Poor hygiene, and hormone imbalances. Hormonal changes in adolescence: Stimulation of the sebaceous glands seems to occur with the production of androgens (the masculinizing hormone found in both sexes) at puberty.
- Food and cosmetics allergies are cause of some of the worst cases. - In general, bad digestion, leads to the inability to absorb important nutrients and is a major cause of acne.
- Genetic factor.
