基于皮肤3D快速成像技术对唇部和唇周皮肤衰老分析

A study on the lip and perioral aging via fast optical in vivo topometry of human skin

采用皮肤3D快速成像系统(简称AEVA-HE)旨在探讨女性唇部及唇周皮肤衰老变化特征。实验选取20名符合条件健康女性志愿者参与测试,并分为青年组和老年组,每组10人,通过采集志愿者面部3D图像,对唇部、唇周皮肤生理参数特征统计分析。结果表明:唇周:青年组和老年组之间皮肤皱纹粗糙度(Ra,Rz)差异性具有统计学意义(P<0.05),青年组唇周皮肤更细腻;下唇纹:对青年组和老年组下唇平滑度(Stm,Sa)比较,未表现统计学意义;唇角:唇部粗糙度和皱纹深度具有统计学意义(P<0.05);唇部:唇部形态参数(Positive volume)结合3D可视化立体形态图,青年组唇部表现更饱满,但未表现统计学意义。结论:通过试验表明AEVA-HE系统可采用客观数据与可视化图像表征唇部和唇周的皮肤纹理结构和形态特征,为化妆品企业与研究机构对唇部和唇周皮肤衰老评价提供技术参考。

The lip and perioral skin aging was evaluated by the fast optical in vivo topometry of human skin(referred to as AEVA-HE).In the experiment,20 eligible healthy female volunteers were selected to participate in the test.The volunteers were divided into a youth group and an elderly group,and each with 10 people.Based on the fast optical in vivo topometry of human skin technology,the 3D topography of all volunteers’skin of lip and perioral skin was collected,and the physiological parameters of the lip and perioral skin were measured,and the skin texture and morphological changes were also statistically analyzed.The perioral wrinkles:compared with the elderly group,the youth group’s perioral skin is more delicate,and the results of wrinkles’roughness(Ra,Rz)show significant difference by statistics analysis(P<0.05).The wrinkles of lower lip:as for comparing the wrinkles of lower lip between the youth and the elderly groups,the parameters of skin smoothness(Stm,Sa)show no significant difference.However,from the data trend and 3D topography,it is observed that the elderly group performs worse.The wrinkles of lip corners:the lip corner wrinkles’roughness,wrinkle depth,volume and area were compared between the youth group and the elderly group.The results of wrinkles’roughness and mean depth show significant difference by statistics analysis(P<0.05).The morphological change of lip:the results show that the youth group has plump lips combined with the parameters of positive volume,positive area and 3D topography.But no significant difference is shown between the youth group and the elderly group.This study shows that the AEVA-HE system can characterize the changes in the skin texture and morphology of the lips and perioral skin’s aging through the objective data and 3D topography,which will provide strong technical support for cosmetic companies and research institutions.
