混合植物油与白油对皮肤的综合作用比较

通过让受试者分别在前臂内侧皮肤（6h短效试验组）和面部皮肤（30d长效试验组）上使用含混合植物油和白油的膏霜样品,考察了混合植物油和白油对皮肤水分含量、经表皮失水率（TEWL）、摩擦力、弹性的短期和长期影响以及对皮肤皱纹的长期影响。结果显示,混合植物油在短期和长期内均能有效提高皮肤水分含量和降低水分流失,长期使用能有效提高皮肤弹性和降低皮肤皱纹面积、皱纹长度、皱纹深度;白油在短期和长期内也能一定程度提高皮肤水分含量和减少水分流失,长期使用对皮肤皱纹深度有降低作用,效果均不及植物油。涂抹后6小时,植物油能降低皮肤摩擦力,白油能提高皮肤摩擦力,长期使用两种油脂均能提高皮肤摩擦力。

Comparison on Comprehensive Influences of Mixed Vegetable Oil and White oil on skin

The creams with mixed vegetable oil and white oil were applied on inside of the forearm and face of subjects for short-term group（6 h） and long-term group（30 d） respectively. The changes of skin moisture, transepidermal water loss （TEWL）, skin elasticity, skin fine lines and friction had been studied. Results showed, vegetable oil could effectively improve skin hydration, reduce TEWL both in short-term and long-term use, had good effect on improving skin elasticity and reducing skin wrinkle area, length and depth after long time using. White oil could also improve skin hydration and reduce TEWL both in short-term and long-term use to some extent, and it had some effect on reducing wrinkle depth after long time using, but those effects were less than vegetable oil. After applying 6 hours, vegetable oil could reduce but white oil could increase skin friction, while both oils could increase skin friction in long-term application.
