In Caucasian females, the wrinkle score in the lower eyelid was very high (3.25) in the group aged 20-29 years, but appeared to reach a plateau in the group aged 40-49 years. Therefore, in Caucasian females, the assessment of wrinkles in all areas of the face, excluding the lower eyelid, and subzygomatic sagging may be possible using photo standards established for Japanese under the age of 60-69 years.

Therefore, to assess wrinkles in this area, new criteria should be established. On the other hand, since photos with the eyes open were used in this study, there were some Caucasian subjects with wrinkles in the upper eyelid that could not be assessed. Shirakabe (10) reported that methods of cosmetic surgery differ between Westerners and Japanese due to differences in facial morphology. To make aged eyes look younger, he depresses the upper eyelids
