For some, however, acne is more serious. In most cases, acne starts between the ages of ten and thirteen and usually lasts for five to ten years. It normally goes away on its own sometime in the early twenties. However, acne can persist into the late twenties or thirties or even beyond.
Some people get acne for the first time as adults.
Acne affects young men and young women about equally, but there are differences. Young men are more likely than young women to have more severe, longer lasting forms of acne. Despite this fact, young men are less likely than young women to visit a dermatologist for their acne. In contrast, young women are more likely to have intermittent acne due to hormonal changes associated with their menstrual cycle and acne caused by cosmetics. These kinds of acne may afflict young women well into adulthood.
