摘　　要：目的:分析中国汉族健康人群的皮肤弹性与年龄和部位的相关性。方法:用无创性皮肤弹性测试仪检测669例中国汉族健康志愿者(平均年龄30.96岁),分别测试前额、左眼角、鼻尖、左鼻唇沟、左颈部、左前臂屈侧、脐周、左胫前皮肤弹性。结果:非暴露部位皮肤弹性相对于面部暴露部位高,参数R1、R4、R9随年龄增加而升高,参数R2、R5、R7随年龄增加而下降,颈部及眼角部位下降最明显,30岁以后下降加快。眼角、鼻唇沟、颈前区、前臂屈侧部位的皮肤随年龄增长表现的更易疲劳。结论:皮肤弹性测试可以无创地量化评价不同年龄,不同部位的人体皮肤弹性,以评估皮肤的老化程度。Objective Using the skin elasticity test device, we analyze age and regional body differences of the viscoelastic properties of healthy Chinese Han subjects. Methods Using non-invasive skin elasticity device, we analyze the viscoelastic properties of Han Chinese subjects without skin disease. A total of 669 healthy volunteers were recruited which were divided the participants into seven groups according to the age differences.The biomechanical properties of the skin were respectively measured respectively using this device on eight body sites：forehead（FH）,crow＇s feet,apex nasi,nasolabial groove,neck,flexible forearm,peripheral umbilicus and anterior bibial. Results The skin elasticity of non-exposed body-sites is higher than exposed on the face.The parameters of R1,R4,and R9 increase with the age, while the parameters of R2,R5 and R7 decline with the age.Among which,the most significant decline is found in the crow＇s feet,especially in the age group of beyond 30. The skin becoming more fatigue during age growth among the crow＇s feet,nasolabial groove,neck,and flexible forearm locations. Conclusion Non-invasive skin elasticity measurement is demonstrated as of great use for the quantitative evaluation of agerelated and region-related changes.
