Like most people, the age of 25 upwards, start acne usually disappear from the skin. Then, how if the acne does not even appear or disappear in the age of full age?

According Jonette Keri, MD, PhD, assistant professor dermatology at the University of Miami Miller School of Medicine, and chairman of dermatology at the Miami VA Medical Center, estimated that 30% of women and 20% men aged 20-60 years (and more) have a problem with a acne.

Causes 
Acne in the age of consent is generally caused by sebum, the oil substance produced by sebaceous gland. This sebum close the pore, and then attract the bacteria and cause inflammation. For some adults, acne arise due to too sensitive to the androgen (male hormone). However, estrogen hormone imbalance in men and women can also cause a acne. For women, this can happen at the time of pregnancy, pre-menopause, and menopause. Some drugs, such as cosmetics kortikosteroid and cumulation in the skin can also cause acne.
