Abstract

Purpose: This study aimed to analyze the differences in skin characteristics such as crow’s feet, visible and invisible spots, pores in the left and right cheek areas of the face, porphyrins, brown spots, and skin color and texture with increasing age.Methods: This study utilized Visia-CR software Mirror® to capture images of the entire face of 457 individuals aged 30–60 years. Facial skin characteristics were analyzed using image analysis software, VAESTRO, and a toolkit. The analysis of facial skin characteristics according to age was performed using one-way analysis of variance to test for significance, followed by Scheffe’s post-hoc test.Results: Significant differences in age-related crow’s feet, visible and invisible spots, brown spots on the left and right cheeks, and skin texture were observed in all age groups, except for groups in their 50s and 60s. Porphyrins, depending on age, showed significant differences between the mean values of the 30s and all other age groups and those of the 40s and 60s. Significant differences in L* and a* according to age were observed between the mean values of the 30s and 50s–60s and those of the 40s and 60s. Significant differences in age-dependent b* were observed between the mean values of the 30s and all other age groups.Conclusion: This study found significant differences in wrinkles, spots, brown spots, and skin color (L*, a*, and b*) with age. However, there were no significant difference in the pores of the facial skin and b* with increasing age. Based on this result, L* and a* are likely to require further research for the age groups in the 30s and 40s, 40s and 50s, and 50s and 60s. In addition, pores and b* require follow-up studies on morphological changes of the facial skin regardless of aging.
面部皮肤生物物理特性随年龄变化的研究
目的:本研究旨在分析随着年龄的增长,鱼尾纹、可见斑和不可见斑、面部左右颊区毛孔、卟啉、棕色斑、皮肤颜色和质地等皮肤特征的差异。方法:本研究使用Visia-CR软件Mirror®对457名年龄在30-60岁的个体进行全面部图像采集。使用图像分析软件VAESTRO和工具包分析面部皮肤特征。根据年龄对面部皮肤特征进行分析,采用单因素方差分析进行显著性检验,然后进行Scheffe事后检验。结果:年龄相关性鱼尾纹、可见斑与不可见斑、左右颊褐斑、皮肤质地在各年龄组中均有显著差异,50、60岁组除外。根据年龄的不同,卟啉在30多岁和所有其他年龄组的平均值与40多岁和60多岁的平均值之间存在显著差异。L*和a*按年龄分布的平均值在30多岁和50 ~ 60多岁与40多岁和60多岁之间有显著差异。年龄依赖性b*与其他各年龄组的平均值有显著差异。结论:本研究发现皱纹、色斑、褐斑、肤色(L*、a*、b*)随年龄有显著差异。但随着年龄的增长,面部皮肤的毛孔和b*没有显著差异。基于这一结果,L*和a*可能需要对30 - 40岁、40 - 50岁、50 - 60岁年龄组进行进一步的研究。此外,毛孔和b*需要对面部皮肤的形态学变化进行后续研究,而不考虑年龄的变化。
