title: Characterization of facial skin of various Asian populations through visual and non-invasive instrumental evaluations: influence of age and skincare habits.
abstract: OBJECTIVE
  We aimed to evaluate the impact of age and skincare habits on facial skin of different Asian ethnicities by comparing skin properties and skincare habits among various Asian populations of varying age groups.
  
  
  METHODS
  We evaluated approximately 100 female subjects each from a total of eight Asian cities in China, India, South Korea, Japan, and the Philippines grouped according to age ranging from 14 to 75 years during a summer season. Facial skin was characterized using dermatological examinations of the cheek and instrumental evaluations of the forehead and cheek. Information regarding personal skincare habits was collected using a questionnaire.
  
  
  RESULTS
  In 834 female subjects, characteristics related to skin surface moisture, elasticity, and sebum level decreased with age. Differences in skincare habits corresponded with variations in skin parameters. Subjects with the least severe photodamage reported a generally early onset of their skincare habits.
  
  
  CONCLUSIONS
  These results demonstrate common trends as well as inherent differences in skin characteristics among Asian populations, reflecting the impact of age and the diversity of skincare habits of Asian women. These results may be beneficial when developing new skincare products that are well suited to these Asian populations.
