A person should consider seeing a dermatologist if they develop cysts, nodules, or deep, painful acne. These severe forms of acne often do not respond to over-the-counter treatments and can lead to permanent scarring if left untreated. Cysts and nodules are large, inflamed bumps that form deep within the skin and can be particularly painful. A dermatologist can provide specialized treatments, such as corticosteroid injections, prescription medications, or extraction procedures, to reduce inflammation and prevent long-term damage.

Another key reason to consult a dermatologist is if acne appears later in life, known as late-onset acne. This condition affects adults who may have never experienced acne during their teenage years. Hormonal changes, stress, or underlying medical conditions can trigger late-onset acne, and a dermatologist can help identify the root cause. Unlike adolescent acne, adult acne often requires a different treatment approach, making professional guidance essential for effective management.
