A person should see a dermatologist if they develop cysts, nodules, or deep, painful acne that does not improve with over-the-counter treatments. Professional care may also be helpful for adults experiencing late-onset acne, which can appear in people who never had acne during their teenage years.
Persistent acne is another reason to consult a dermatologist. This refers to acne that continues from adolescence into adulthood or returns after improving. A dermatologist can help identify possible causes and recommend appropriate treatment to prevent worsening and reduce the risk of scarring.
