Link found between teens' stress levels and acn...( hair follicle and the sebaceous glands ...),Health

The researchers suspected that stress increases the quantity of sebum, which leads to increased acne severity. However, the results showed that sebum production didnt differ significantly between the high-stress and low-stress conditions.

The researchers did find that students reporting high stress were 23 percent more likely to have increased severity of acne papulopustulosa. Levels of stress were not linked to severity of acne comedonica.

"Our research suggests that acne severity associated with stress may result from factors others than sebum quantity," said Yosipovitch. "Its possible that inflammation may be involved."

Singapore was selected as the study location because sebum production is known to fluctuate with variations in temperature and humidity. In Singapores tropical climate, temperature and humidity are consistent throughout the year.
