Background: Healthy skin is an important determinant of the quality of life and physical and mental well-being. The demand for dermatological information is increasing not only in patients with skin diseases, but also in the general population with normal/healthy skin. However, public perception and behavior with regard to skin health among Koreans are not known. Objective: To examine public perception and behaviors with regard to skin health in Koreans visiting the Skin Health Expo 2017. Methods: A total of 597 participants completed a questionnaire that assessed demographics, status, and behavior for skin health and Expo satisfaction. Results: Respondents with higher stress levels and a history of skin diseases showed lower satisfaction with self-skin health. Most participants considered adequate sleep and water intake to be important factors associated with healthy skin. One-on-one consultation with dermatologists was the most satisfactory among participants at the Expo. Conclusion: Educational tools using mass media and informative activities such as the Expo planned by dermatologists and the government are necessary to spread awareness and provide proper information to improve skin health in thegeneral population and to emphasize the key role of dermatologists in skin disorders with a social burden.
