季节因素对广州地区健康女性面部皮肤粗糙度指标的影响及校正

目的：探讨季节的变化对广州地区健康女性面部皮肤粗糙度指标的影响并建立季节性校正公式。方法：使用Visioscan（r）VC98仪器测量178例健康女性受试者颧部和眼角部皮肤粗糙度指标值的四季变化,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。结果：颧部皮肤粗糙度指标,最差的是秋季,最好的是春季,二者比较差异有统计学意义（P〈0.05）;眼角皮肤粗糙度指标,秋季和冬季较好,夏季和春季较差,秋季和冬季均明显差于夏季和春季（P〈0.05）。结论：抗皮肤衰老功效或疗效评估要考虑季节因素对皮肤粗糙度指标的影响,季节性校正公式可以校正季节对皮肤粗糙度指标的影响。

Analysis of Seasonal Influence on Facial Skin of Healthy Female in Guangzhou District

Objective：To investigate the seasonal influence of facial skin healthy female in Guangzhou city and set up the formula to rectify seasonal variation. Methods：178 healthy females were involved in this study,the seasonal variation of female facial skin roughness were evaluated by instrument.The correlations between skin roughness and humidity,and UV radiation level were analyzed.Results：Roughness of female cheekbone skin was at the lowest level in Spring（P0.05）,and at the highest level in Autumn（P0.05）.Significant positive correlation between skin roughness and ultraviolet radiation level（P0.05） and significant negative correlation between skin roughness and humidity（P0.05） were found.Conclusion：For evaluation of efficacy in treatment or in anti-skin aging,one should take into consideration the influence of seasons on skin roughness.An established formula of seasonality rectification could eliminate the seasonal effect on the facial skin roughness.
