BACKGROUND/PURPOSE: This study aimed to reveal gender-dependent differences in the degree of facial wrinkles.
Subjects comprised 173 Japanese men and women, divided into four groups according to age. Photographs were taken from nine facial regions and used to classify the intensity of wrinkles into five grades. In addition, replicas were taken from five facial sites and used to measure surface roughness. Data were compared between men and women within each age group.
In all age groups, men showed increased forehead wrinkles compared with women. In contrast, no gender-dependent differences were found in upper eyelid wrinkles. Other facial wrinkles were greater in men than in women in all except the oldest group (age, 65-75 years), in which wrinkles in women were greater than or equal to those in men.
Our results showed that gender-dependent differences exist in the degree of facial wrinkles. In general, men tend to have more severe wrinkles than women. This tendency disappeared or was reversed in some regions of the face and in individuals more than 60 years old.
背景/目的：本研究旨在揭示面部皱纹程度的性别差异。
研究对象包括 173 名日本男女，根据年龄分为四组。从九个面部区域拍摄照片，并将皱纹强度分为五个等级。此外，还从五个面部部位采集复制品，用于测量表面粗糙度。在每个年龄组内比较男女之间的数据。
在所有年龄组中，男性的额部皱纹比女性更明显。相比之下，在上眼睑皱纹方面，男女之间没有性别差异。除了最年长的一组（年龄 65-75 岁）外，其他所有面部皱纹男性都比女性明显，而在这一组中，女性的皱纹与男性相当或更明显。
我们的研究结果表明，面部皱纹程度存在性别差异。一般来说，男性的皱纹比女性更严重。这种趋势在某些区域和 60 岁以上的个体中消失或逆转。
