Cause of Acne
Hormones are responsible for triggering glands to produce sebum, which is used to lubricate the skin. However, an excessive amount of sebum can lead to acne.
So, what exactly is the cause of acne? A number of factors can contribute to the condition, including genetics, hormonal activity, dead skin cells and stress. But regardless of the root cause, all of these conditions result in the same problem - clogged pores.
Genetics
Genetic make-up can contribute to acne. For instance, the chances of developing acne are increased if a person's parents also suffered from the condition.
Hormonal Activity
Hormones play a major role in the production of acne. Hormones are responsible for triggering glands to produce sebum, which is used to lubricate the skin. However, an excessive amount of sebum can lead to acne. The extra sebum combines with dead skin cells and a skin bacteria known as Propionibacterium acnes (P. acnes), which together form a clog in the skin's pores.
Stress
For years, many people have pointed to stress as a cause of acne. On the other hand, many believe that the pimples themselves result in stress. Until recently, there was little research linking stress to acne. However, a 2007 study suggests that stress does cause acne. Researchers at Wake Forest University School of Medicine studied several students in Singapore, and found that adolescents experiencing high stress levels are 23 percent more likely to experience an increase in acne severity.
Diet
A person's diet is often blamed for their pimples. Some believe that chocolate or caffeine can cause acne. But these claims have long been dismissed. A study published in the July 2007 issue of the American Journal of Clinical Nutrition reports that low-glycemic diets - those including carbohydrates that break down slowly such as high-fiber cereals and beans - can actually significantly reduce total acne compared with normal, high-glycemic diets that include white bread and potatoes.
