For those aged between 11 and 30, acne is very common; approximately 80 percent of that age group suffers from it. What’s more, the condition can also occur in older age brackets or last well beyond teenage years. It is, however, seen most frequently in teenagers and coincides with the changes of puberty – hence its associations with them.

Girls are usually the first to experience acne, which arrives somewhere between 14 and 17 years of age. It generally develops a little later in boys and occurs anywhere from 16 years old to 19 years old. Regardless, the condition usually ebbs and flows for years until it finally fades away. And while acne often disappears midway through the sufferer’s 20s, that’s not always the case.

In a small percentage of people, though, symptoms persists past the expected acne-free age of 25. Only one percent of males experience the condition beyond that age, although it’s slightly more common in women. In fact, around five percent of females have acne in their adult life. So why is it mostly seen in teenagers?
