探討市售保濕化粧品之功效性評估

由於內、外在環境的變化加速影響，導致多數人的肌膚自然及光老化程度加速，外來的課業、工作、家庭壓力沉重，亦易導致皮膚缺乏水份、過敏及荷爾蒙失調等，進而造成皮膚彈性逐漸降低，希冀本研究對市售保濕化粧品功效性做一深入探討。本研究使用市售保濕化粧品塗抹於皮膚，進行化妝品功效性評估與分析觀察其化粧品對皮膚之影響，採化粧品功效性評估方式包含速效性和持效性方法，以觀察化粧品對皮膚的功效性變化做一交叉比較。首先將受測者分成甲組及乙組，甲組採用保濕系列之保養品做為一般性的基礎肌膚保養，乙組採用保濕系列之保養品再加保濕面膜做特殊性肌膚保養，接著進行速效性及持效性之化粧品功效性評估。經由市面上安全之保濕護膚產品，依所設定條件下塗抹保養護膚品，使用多功能皮膚生理檢測系統及膚質檢測儀檢測及記錄受測者皮膚之變化，檢測項目包含保濕度、經皮水分散失率及肌膚紋理的變化；另觀察臉頰保濕度的變化與化妝品、時間、相對濕度的關係。藉由使用產品前、後的差異顯示乙組比甲組的功效性成效有顯著改變，尤其是保濕度效果及經皮水分散失率有明顯下降。

Due to the accelerated influence of changes in the internal and external environment, most people's skin aging is intensified. In addition, schoolwork, job, and family stress are heavy, which can easily lead to skin's lack of moisture, allergies and hormonal disorders, etc. This study hopes to do an in-depth discussion on the efficacy of commercially available moisturizing cosmetics. The study evaluated the effectiveness of commercial moisturizing cosmetics for skin. The subjects were investigated the effectiveness of moisturizing for their skin before and after using these tested products. The products were selected with safety concerns. Before the study, the researchers adopted a multi-functional skin physiology detection system and VISIA skin quality tester to detect the comparison before and after the skin testing. Accordingly, the researchers examined the changes in water retention of the cheeks, transdermal water loss rate, measure the skin at the test site The differences were included between the change in humidity retention and the tested product, the test time, the measured relative humidity, and the expected improvement in the humidity retention effect. The results of this study understand the effectiveness of commercial moisturizing cosmetics. By means of the differences before and after using these products, the study revealed the significant differences between the two groups. In other words, the effectiveness in Group B were higher than that in Group A. In Group B, the moisturizing effects were more stable and the spreading rate was significantly decreased.
