Photographic scale for wrinkles in Koreans. This scale can probably be applied to the inhabitants of other East Asian countries, but applies particularly to Koreans, Japanese and Chinese. Grade zero represents the absence of any wrinkles and grade 7 indicates a severely wrinkled status. Because the pattern of wrinkling is the same for both Korean genders, this photographic scale can be used for women and men.
