A person should consider seeing a dermatologist if they develop cysts, nodules, or deep, painful acne. These types of breakouts can be more difficult to manage and may require professional treatment.
A dermatologist can also help with late-onset acne, which develops in adulthood in someone who did not previously have acne, as well as persistent acne that continues or returns after adolescence.
Getting professional advice can help identify the type of acne and determine an appropriate treatment approach, especially when breakouts are severe, painful, or ongoing.
