Table V compares the wrinkle scores between Cau­ casian and Japanese females in eight areas of the face and the sagging scores in the subzygomatic area. The wrinkle score in each area was significantly higher in the Caucasian females than in the Japanese females in the young groups aged 20-29 years. The Caucasian females showed especially high wrinkle scores in the lower eyelid, naso­ labial groove, cheek, and the corner of the mouth at all ages, and a marked increase in the subzygomatic sagging score in the group aged 40--49 years.

(continued) 60s � 60s 381 □ Caucasian □ Japanese □ Caucasian B Japanese nasolabial groove, cheek, and the corner of the mouth are considered to be due to subzygomatic sagging (7), Caucasian females may tend to develop wrinkles in their faces from a young age, and become more susceptible to sagging than Japanese females during the middle and later years. 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.
