For human skin, high water content and low sebum secretion are considered to be main features of fair skin. To explore the proper personal care regimen for facial skin, we investigated the change of skin physiologic parameters after cosmetic application by measuring the skin water content, transepidermal water loss, and skin sebum secretion on facial skin before and after the cosmetic application using the Corneometer, Tewameter, and Sebumeter, respectively. The results indicated that the cosmetics application kept a higher water content and a lower transepidermal water loss, and at the same time, a lower sebum secretion 4 h and 8 h after the cosmetic application, compared with those before it. The situation was maintained in the succeeding three-week continuous use of the cosmetics. It could be concluded that the cosmetic application on human facial skin might provide some moisturizing effect and at the same time an anti-sebum effect, which favors the maintenance of good skin physiological function after applying skin care products. Our results might provide a scientific personal care regimen for human facial skin to prompt the balance for the hydrolipid film on skin.
对于人类皮肤而言，高含水量和低皮脂分泌被认为是白皙皮肤的主要特征。为了探索适合面部皮肤的个人护理方案，我们通过分别使用角质层水合测量仪、经皮水分流失测量仪和皮脂分泌测量仪，在使用化妆品前后对面部皮肤的含水量、经皮水分流失和皮脂分泌进行测量，从而研究了使用化妆品后皮肤生理参数的变化。结果表明，与使用化妆品前相比，使用化妆品后4小时和8小时，皮肤保持了较高的含水量和较低的经皮水分流失，同时皮脂分泌也较低。在连续使用该化妆品的后续三周内，这种情况得以维持。可以得出结论，在人类面部皮肤上使用该化妆品可能会提供一定的保湿效果，同时具有抗皮脂分泌的作用，这有利于在使用护肤品后维持良好的皮肤生理功能。我们的研究结果可能为人类面部皮肤提供一种科学的个人护理方案，以促进皮肤水脂膜的平衡。
