Acne can vary in terms of when it stops for individuals. In general, for many people, acne tends to improve as they move through their 20s, and for some, it may continue into their 30s or even beyond. Typically, acne tends to lessen and improve with age due to hormonal changes and lifestyle factors. However, it’s important to note that some individuals may struggle with acne into their 40s and beyond. If acne is a persistent concern, it may be advisable to consult a dermatologist for personalized advice and treatment options.
