Acne is a condition of the skin, which causes spots, especially on the face, shoulders and upper back. Acne tends to begin at puberty, and although most sufferers are over it within a few years, it may carry on for life. Spots form in the glands of the skin that produce protective oils (sebaceous glands). The places where the spots usually occur are the face, shoulders, and upper back.
Acne may result in small spots which known as "blackheads" (or open comedones); Small spots which are white in colour, known as "whiteheads" (or closed comedones);These may become infected by a germ or bacterium (Propionibacterium acnes) which makes the spot inflamed, and results in a larger raised spot (papule), a spot filled with pus (pustule) or a hardened lump (nodule);The largest spots are more likely to leave lasting scars.

Acne Defined
Acne vulgaris (common acne) is a condition of the sebaceous glands of the skin. The sebaceous glands surround each hair follicle and produce sebum, an oily substance, to lubricate the hair. Acne usually appears on the face, back and chest.
Acne is the most common skin disease during adolescence and early adulthood. It peaks in females between the ages of 14 and 17 and in males between the ages of 16 and 19. Males are affected more severely than females. Eighty-five percent of high school students will have some acne. Ten percent of those with adolescent acne will continue to suffer from acne into their 20's and 30's. And sometimes "adult acne" will begin in the 20's, 30's and 40's and later years and continue due to stress and fatigue which can cause increased production of hormones by the adrenal gland with increased levels of androgens. These hormones worsen acne. Six percent of females and eight percent of males in their fifties and later still suffer from acne. Acne affects more than 17 million adult Americans and approximately 60 million adults in other countries.
Acne usually begins one to two years before puberty and is caused by stimulation of the facial sebaceous glands by androgens, the male hormones. (Women also produce small quantities of male hormones; this is the basis of acne in women.) It is thought that acne sufferers, rather than having higher levels of the hormones, actually have sebaceous glands that are more sensitive to the hormone.

The Occurrence of Acne
When your skin pores start to be clogged up with greasy, oily stuff, causing inflammation to occur, a skin condition known as acne results. If left untreated, acne could produce permanent scarring on one’s face, neck, or back. Acne is different from the common pimple that appears on the face, because acne will be inflamed and might turn out to be an infection. Acne can appear as whiteheads (closed pimples) or blackheads (open pimples), which then cause the distinguishing inflammation and possible infection.
When children begin to turn into adults, their levels of hormones causes changes in skin gland size, which causes more oil to be produced by the glands, thus often resulting in acne. The majority of acne is minor and vanishes at the end of teen years, but inflamed, infected acne can result in serious scarring.
Contrary to popular belief, there is no known study that shows particular foods, such as chocolate, cause acne. Proper diet and exercise will result in healthier skin, but will not necessarily prevent acne from appearing.
Mild forms of acne can be controlled by washing with a soft mild soap several times a day, and by refraining from picking at pimples while they are healing. There are several acne medications on the market that can control acne, but cosmetics and oil-filled lotions should be avoided when treating it.
