摘要
目的:产生评价演播室中使用的一种LED光源对人皮肤颜色和皮肤屏障功能的影响。方法:选择了30名健康女性志愿者,以照度为2800lxLED光源照射上臂屈侧的皮肤,照射时间15分钟,每天照射一次,连续照射30天。比较照射前后反应皮肤颜色的L*a*b*值、M和E值以及角质层含水量和经皮水分丢失。结果:照射前后L*a*b*值、M和E值以及角质层含水量和经皮水分丢失均无统计学差异。结论:演播室中使用的此种LED光源短期照射对人体肤色和皮肤含水量无影响。
To evaluate the effects of a kind of LED light source used in the teletorium on human skin color and skin barrier. Methods： The upper arm flexor skins of 30 health females were exposed to LED light source, once a day for 30 days. The illumination was 2800x. After exposure the changes of L ＊ a ＊ b ＊ , M, E values and water content of corneum layer and transepidermal water loss （TEWL） were measured. Results ： There were no statistic significances for the changes of L ＊ a ＊ b ＊ , M, E values and water content of corneum layer and TEWL after exposure. Conclusions： In short time exposure, this kind of LED light source used in teletorium was not harmful on human skin color and skin barrier.
