Thanks for the question.
Acne often does improve as you grow older and many people do 'outgrow' their acne.
However, acne vulgaris can persist into adulthood in 15 to 25% of individuals. It is difficult to predict who will get persistent adult acne. Some individual may have underlying conditions like polycystic ovarian syndrome which can cause the acne to persist.
It is best to get active acne treated and not wait for the acne to outgrow. Acne treatment can help control the acne and improve the appearance, but importantly, it prevents acne scars from forming, which may be permanent.
You should consider seeing your doctor or dermatologist for treatment of your acne.
