Acne is found quite often in pubescent individuals. Because of a high genetic disposition to the condition, acne is particularly common in Western societies. It is believed that the presence of acne is due to an abnormal response to normal levels in the body of testosterone, the male hormone. For many individuals, this response tends to diminish over time, causing the acne to decrease by the time they reach their 20′s, or even disappear. Unfortunately, it is impossible to tell how long it will take for acne to completely disappear; for some people they may experience it for many decades- even beyond their 30′s or 40′s. A large number of people will experience this condition at some point in their life.
