Abstract
|
|
|
To investigate the alleviative effect of white tea water extract on the inflammation and skin barrier damage, skin aging
animal model was produced by the irradiation of UVB to the backs of hairless mice for 12 weeks. And then experimental
materials were applied topically for 4 weeks. At the 28th day of experiment, positive control (PC, 0.01% retinoic acid
treatment) and experimental groups (E1, 1% white tea water extract treatment; E2, 2% white tea water extract treatment)
had significantly (p?0.001) lower values of both skin erythema index and transepidermal water loss (TEWL) than the
control (C, saline treatment) group. The appearance of mast cell and the degree of its degranulation in dermal and subcutaneous layers were remarkably reduced in E1 and E2 groups compared to the C group. It is found that white tea water extract is effective in skin barrier damage and inflammation in hairless mouse.ㄹ
