A person should see a dermatologist if they have cysts, nodules, or deep, painful acne. These severe forms can cause scarring and need professional treatment.
Cystic and nodular acne often don’t improve with regular products. A dermatologist can offer stronger, more effective options.
Adults who suddenly develop acne, known as late-onset acne, should also seek medical advice. It may be linked to hormones or other health issues.

Persistent acne that continues from teen years into adulthood is another reason to see a dermatologist. Proper care can prevent long-term skin problems.
