Background: Cosmetics can affect the skin condition profoundly, and yet no survey has been performed in Koreans visiting dermatology clinics. Objective: To assess knowledge and consumer behavior regarding cosmetics in Koreans visiting dermatology clinics. Methods: A questionnaire consisting of 43 questions concerning demographics and use/knowledge/selection/purchase of cosmetics was given to patients and accompanying persons who visited dermatologic clinics in university and private clinic settings. Results: In total 1,015 subjects (73.2% females, mean age 32.5 years) completed the survey. Education level was college or higher in 72.8%. Thirty-one percent had been diagnosed with a skin disorder, atopic dermatitis and seborrheic dermatitis being the most frequent diagnoses (33.7% and 16.8%, respectively). The frequency of makeup/sunscreen/functional cosmetics use, amount of sunscreen use, recognition of functional cosmetics, and knowledge of shelf life were significantly correlated with level of education. Among "functional cosmetics," whitening products were used most frequently (29.2%). Regardless of education level, 79.2% purchased cosmetics without checking ingredients, and 85.7% were unaware of the all-ingredient-labelling regulations, and yet subjects considered ingredient the most important factor when purchasing a product. Conclusion: Outpatient subjects in their twenties and thirties are the most knowledgeable about cosmetics in Korea.
