A survey found that people with acne that persists despite treatment are more likely to use a double-cleanse method and use a higher number of cosmetic products compared with patients with treatment-naïve acne, suggesting cosmetics may influence the persistence of acne duration and severity. Findings from this survey were published in the Journal of Cosmetic Dermatology.
The survey included 539 patients with acne vulgaris who had visited 1 of either 3 dermatologic clinics in Korea.
