摘　　要：目的探究不同肤色分型的中国女性皮肤白皙肤质的指标差异,为健康美白皮肤护理和美白产品配方设计提供理论依据和建议。方法以ITA°作为肤色分组依据,由高到低分为Ⅰ~Ⅵ型6种类别。通过观察和询问方式进行受试者筛选,一共招募入组面部无明显皮损的正常皮肤健康女性147例,年龄区间20~45岁。使用无创测试仪器及图像分析仪器采集面部皮肤颜色、生理参数、光学参数和表面形貌共26个指标数据。以ITA°作为肤色分组依据,受试者由高到低一共分为Ⅰ~Ⅳ型4组,主要集中于Ⅱ型和Ⅲ型。使用统计软件对组间数据进行差异显著性分析和相关性分析。结果Ⅱ型组别86人,平均年龄(36.88±5.33)岁;Ⅲ型组别55人,平均年龄(40.40±4.16)岁。Ⅱ型皮肤人群的L^(*)值、a^(*)值、b^(*)值、ITA°、H_SD、S_SD、MI值、EI值、TEWL值、镜面率R/G/B、SEr、SEsc、R4与Ⅲ型皮肤人群具有显著性差异(P<0.05)。在Ⅱ型人群中,L^(*)、MI值、镜面率G/B、S_SD与ITA°具有显著的相关性(|相关系数|>0.4),b^(*)值、I_SD、EI值、粗糙度R1/2/3/4/5、SEsc和a^(*)值与ITA°具有显著的弱负相关性(-0.4<相关系数<-0.2)。在Ⅲ型人群中,L^(*)、MI值、镜面率G/B与ITA°具有显著的相关性(|相关系数|>0.4),EI值与ITA°具有显著的弱负相关性(-0.4<相关系数<-0.2)。与Ⅲ型人群数据相比,表面形貌与ITA°的相关性只在Ⅱ型人群中出现。结论更浅的肤色伴随着高亮度、低红度、低黄度、高肤色均匀度、低色素水平、高透光度、低鳞屑水平、低粗糙程度和更稳定屏障功能的特点。浅肤色人群中,皮肤表面粗糙程度和鳞屑情况可能更容易影响皮肤的白皙感知。Objective To find out the difference of white skin appearance of Chinese females with different color types,and to offer theoretical and scientific advice for healthy white skin care and formula design.Methods The skin color type could be divided intoⅠ-Ⅵ6 types according to ITA°.Non-invasive probes and image analysis system were applied to collect data from 147 healthy women facial skin aged 20-45 years old,with a total of 26 parameters in four aspects involved skin colour characteristic,basic physiological characteristic,optical characteristic and surface topology.Participants were grouped into different skin colour typing by ITA°value.The significance test and correlation analysis were used to data analysis.Results According to the enrollment,the color typeⅡ(36.88±5.33 years)andⅢ(40.40±4.16 years)groups were chosen.Based on the experimental conditions of this work,L^(*)values,a^(*)values,b^(*)values,ITA°,H_SD,S_SD,MI values,EI values,TEWL values,SpeculaRate_R/G/B,SEr,SEsc,and R4 of the skin typeⅡpopulation were significantly different from those of the skin typeⅢpopulation(P<0.05).In typeⅡgroup,L^(*),MI,S_SD and SpeculaRate_G/B had a significant correlation with ITA°(|r|>0.4).b^(*),I_SD,EI,H_SD,R1/2/3/4/5,SEsc,and a^(*)had a significant weak negative correlation with ITA°(-0.4<r<-0.2).In typeⅢgroup,L^(*),MI and SpeculaRate_G/B had a significant correlation with ITA°(|r|>0.4).EI had a significant weak negative correlation with ITA°(-0.4<r<-0.2).Compared with typeⅢgroup,the correlation between surface topology and ITA°was only existed in typeⅡgroup.Conclusion The lighter skin equips the qualities of higher luminosity,lower redness and yellowness,higher skin colour evenness,lower pigmentation,higher transparency,low scaling levels and roughness,and more stable barrier function.For lighter-skinned people,the surface roughness and scaly condition may be more likely to influence the perception of fair skin.
