摘要
Abstract
In order to assess the responses of different skin types stimulated by tape stripping,two kinds of brand cosmetics of cream and hydrogel were separately applied to evaluate the individual soothing effect of the product on different skin types.A total of 30 volunteers aged 18～65 years were recruited,which were divided into four groups(oily,dry,normal and combined skin type)according to the oil secretion ability of facial and T zone skin.Four 3×3 cm of skin areas on inner forearm of each volunteer were chosen and randomly marked as blank,negative control,soothing cream and soothing gel.The blank area was kept untreated,and the remaining areas were tape-stripped by 10 times(Transparent universal 1527C-1,3M China Co.,Ltd.)to disrupt the stratum corneum and induce erythema.Images,erythema index(EI)and transepidermal water loss rate(TEWL)of the marked skin areas before and 5 min after tape stripping were taken to assess the distinct responses of different skin type to the taping treatment.Ten minutes after tape striping,the soothing products were applied to the test area,and the skin images,EI and TEWL at 20 min and 50 min(corresponding to 30 min and 60 min post stripping test,respectively)were measured after cosmetics application to compare and evaluate the soothing effect of the cream and hydrogel on different skin types.Results showed that different skin displayed diverse reactions to the tape stripping,and the oily skin was more sensitive with longer duration of erythema than other skin types.After the application of soothing products,both cream and hydrogel could relieve skin erythema,while the soothing effects are dependent both on skin types and the cosmetic base materials:hydrogel has a better efficacy in alleviating erythema and TEWL of dry skin,while the cream is more effective on normal,oily and combined skin types.The results suggest that the soothing evaluation should consider the skin types of the volunteers,and the cosmetics of different base materials might have the target skin types.关键词
