See a dermatologist.: Acne can be problematic even into adulthood. Regardless of the causes whether overactive sebaceous glands, inflammation, or bacterial overgrowth, a dermatologist can write you a prescription (or two) to alleviate one or more causes of adult acne. Some excellent products include the retinoid category, topical antibiotics, benzoyl peroxide and salicylic acid.
