Pimple
From Free net encyclopedia
Image:Akne-jugend.jpg A pimple is a type of skin lesion caused by inflamed and/or obstructed pores. The most common cause of pimples is acne, but other causes, such as smallpox, exist.
Acne is a common disorder characterized by clogged pores and pimples in the skin. Acne is not a serious health threat, but it can cause permanent scars, as well as often causing pain or itching of the affected skin. Many people with acne are acutely self-conscious about the condition, and as it frequently occurs in adolescence, it may exacerbate the shyness which is common at this age.
Causes
The tiny pores connect to oil glands under the skin. These glands make up an oily substance called sebum. The pores connect to the glands by a canal called a "follicle". Inside the follicles, oil carries dead skin cells to the surface of the skin and a thin strand of hair grows through the follicle and out to the skin. When the follicle of a skin gland clogs up, a pimple will grow.
Misconceptions about acne
There are many myths about what causes acne. Greasy foods and chocolate are often blamed, but foods have little effect on the development and course of acne in people. Another common misconception is that dirty skin causes acne; however, blackheads and other acne lesions are not caused by dirt. Stress does not directly cause acne either. It is true, though, that anger and stress affect hormone levels and thus bodily oil production, which can cause acne. People of all ages and races can get acne. It is most common in adolescents and some young adults. 85% of people between the ages of 12 and 24 develop acne. For most people, acne tends to go away around the time they reach their thirties; however, some people in their forties and fifties continue to have this skin problem.
