Abstract
In order to explore the correlation of 3 different methods of evaluating the degree of skin redness,45 healthy Chinese subjects aged 18～45 were recruited to attend a human efficacy evaluation test.An emulsion product which declares soothing and repair efficacy was used each time in the morning and evening for 4 weeks.Three methods,including visual assessment,image analysis and instrument measurement,were taken to test the related indexes of skin redness degree respectively.The improvement of skin redness and the correlation of 3 methods were evaluated by comparing the changes of each index before and after using the product.The results show that the face redness degree score and the image analysis a* value significantly reduce at all time points after using the sample(P<0.05),while the instrument probe a* value significantly reduce at the time point after using for 2 weeks(P<0.05).The correlation coefficient of the face redness degree score and the instrument probe a* value is more than 0.33 and less than 0.67,and the significance level is less than 0.01.Therefore,the sample has soothing and repair efficacy for improving skin redness,and the methods of visual assessment and instrument measurement present moderate positive correlation.关键词
