女性皮肤弹性与年龄和部位的相关性研究

Studies of the relevance between skin elasticity,age and bodysites

目的:采用无创弹性检测技术研究女性皮肤弹性与年龄和部位的关系。方法:对50名以室内工作为主,年龄为20～78岁的汉族女性健康志愿者采用皮肤弹性仪Cutometer MPA 580(Courage and Khazaka,Cologne,Germany)检测前额、眼角、颧部、前臂屈侧正中和下腹五个部位的皮肤弹性。结果:面部曝光部位弹性参数较相对非曝光部位前臂内侧和腹部低,皮肤弹性与年龄的统计学意义呈负相关,40岁以后变化更明显。结论:无创性皮肤弹性检测技术能显示不同年龄和部位皮肤弹性的变化规律,可量化地揭示二者的相关性。

Objective To study the relationship between the skin elasticity and age in different body sites with nonevasive elasticity measurement technology. Methods 50 healthy women volunteers（20～78 years old） who work inside the room were chosen. The skin elasticity of forehead, crows feet, left cheekbone, flexible forearm and lower abdomen were examined with Cutometer MPA580（Courage and Khazaka,Cologne,Germany）. Results The skin elasticity of sun-exposed body-sites on the face is lower than relatively sun-protected body-sites such as the flexible forearm and lower abdomen.The relationship between skin elasticity and age is statistically negative correlation,especially obvious after 40 years old. Conclusion Non-evasive skin elasticity measurement can show the rule of skin elasticity changes in different body sites and ages,which is a good way for the study of skin ageing.
