[摘要]目的:探讨季节的变化对广州地区健康女性面部皮肤弹性的影响,并建立季节性校正公式。方法:使用皮肤弹性测量仪对广州地区178例健康女性受试者面部皮肤弹性指标进行四季的测量。采用SAS8.1专用统计软件进行数据分析并拟合出季节性校正公式,与环境中紫外线辐射水平和温度湿度水平进行相关分析。结果:皮肤弹性参数R2,R5和R7的值在春季最大,夏季次之,冬季最小;R2值和R5值除春季和夏季之间比较无明显差异外(P>0.05),其他季节之间比较均具有明显差异(P<0.05),R7值各季节之间比较均有明显差异(P<0.05)。各弹性参数值与紫外线辐射水平呈负相关,与温度和湿度水平呈正相关。结论:以皮肤弹性指标的化妆品功效试验或美容激光等治疗疗效的评估要考虑季节因素对皮肤弹性数值的影响;建立的季节性校正公式可以消除季节对面部皮肤弹性数值的影响。

Abstract:ObjectiveTo investigate the seasonal variation of female facial skin elasticity in Guangzhou city and set up the formula of seasonal rectification.Methods178 healthy females were involved in this study,the seasonal variation of female face skin elasticity were evaluated by instrument. The correlations between skin elasticity and humidity,and temperature,and UV radiation level were analyzed by SAS8.1.ResultsThe female facial skin elasticity in spring was the highest,and the lowest in winter,and the R2 and R5 values show obvious difference in different seasons apart spring and summer(P<0.05).R7 values show obvious difference in different seasons(P<0.05). Significant positive correlations between skin elasticity and humidity and temperature and significant negative between skin elasticity and ultraviolet radiation (UVR) level.ConclusionsThe evaluation of efficacy or of clinical effect of ant-skin aging would take into account the influence of seasonality on skin elasticity. An established formula of seasonality rectification could eliminate the seasonal effect on the facial skin elasticity. The healthy female facial skin in Guangzhou city changed with the seasonal variation. The formula of seasonal-revised may eliminate the facial skin elasticity effects by seasonal change.
