What is Acne?

Acne is the most common of all skin disorders. Almost everyone will have acne, most get mild cases, some moderate and a few are severe. Teens aren’t the only ones who get it. Acne has been diagnosed in young infants as well as in the elderly, but it is most often seen in teens and young adults with 85-100% of adolescents and up to 10% of young adults getting it.

Acne can appear on the skin as any of the following:

• Congested pores ("comedones")
• Whiteheads
• Blackheads
• Pimples ("zits")
• Pustules
• Cysts (deep pimples, boils)

Acne happens when oil (sebaceous) glands come to life around puberty, stimulated by male hormones from the adrenal glands of both boys and girls. Sebum (oil) is a natural substance which lubricates and protects the skin, and under certain circumstances, cells that are close to the surface block the openings of sebaceous glands and cause a buildup of oil underneath. This oil stimulates bacteria (which live on everyone's skin and generally cause no problems) to multiply and cause surrounding tissues to become inflamed.

Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); deeper still and it's a cyst. If the oil breaks though to the surface, the result is a "whitehead." If the oil accumulates melanin pigment or becomes oxidized, the oil changes from white to black, and the result is a "blackhead." Blackheads are therefore not dirt, and do not reflect poor hygiene.
