摘要
目的:探讨护肤品对面部皮肤影响的量化评价。方法:将272名受试者按面部防晒霜、保湿类护肤品及洗面奶(液)使用方式分每日使用组、不规律使用组、不使用组三组。采用医生主观评分、角质层含水量测定、黑素指数(melanin index,MI)测定、红斑指数(erythema index,EI)测定、皱纹图像分析方法,评价面部护肤品对皮肤状态的影响。结果:使用护肤品可降低皮肤主观评分、提高角质层含水量、降低MI值和EI值、使皱纹图像分析仪(Visioscan VC98)的绝大多数灰度参数以及SELS参数中平滑度参数向有利于皮肤状态如皮肤变光滑、皱纹减少等方向变化。结论:面部护肤品对皮肤状态存在有利的影响,对延缓皮肤老化起到了一定的防护作用。
