Acne is a common skin condition that can affect people of all ages. The age at which acne goes away varies from person to person and depends on several factors, including the underlying cause of acne. Here are some key points from the search results:

• Teenage acne usually lasts for five to 10 years, normally going away during the early 20s.
• For everyone, not just teenagers, acne is caused by heredity and hormones. With a family history of acne while going untreated, it may never disappear.
• Studies show that 26% of 40-year-olds and 12% of 50-year-old women have acne.
• Adult acne can occur in people in their 30s, 40s, and even 50s, and it is even possible to get acne for the first time as an adult.
• Women tend to get adult acne more often than men do, and it is most common among women going through menopause.
• If your acne continues to show up when your hormones are stable, it’s possible that your pimples are not hormonal at all (meaning they aren’t going to go away just because you’re getting older). Acne can be caused by several factors, including PCOS, genetics, anxiety, stress, and certain skincare products.

In summary, there is no specific age at which acne goes away. It varies from person to person and depends on several factors, including the underlying cause of acne. While teenage acne usually goes away during the early 20s, adult acne can occur in people in their 30s, 40s, and even 50s. If underlying factors of acne are not addressed, it may never disappear.
