化妆品保湿与皮肤纹理的相关性研究

Study on the correlation between moisturizing of cosmetics and skin texture

通过无创性评价方法测试使用保湿护肤品后的皮肤角质层含水量、皮肤油脂含量、皮肤纹理参数,结合消费者测试,分析探讨市场上保湿护肤品的保湿性和皮肤纹理的相关性。结果表明,皮肤纹理参数和皮肤角质层含水量及皮肤油脂含量有一定的负相关性,增加皮肤角质层含水量和皮肤油脂含量都能在一定程度上降低皮肤纹理;消费者能感受到的产品保湿性和仪器测试所得的皮肤纹理参数呈负相关。本研究表明,通过随机双盲对照实验,能比较客观反应化妆品保湿和皮肤纹理的相关性。

The moisture content of stratum corneum, the skin oil content and the skin texture parameters after using moisturizing products were tested by non-invasive evaluation method. Combined with consumer testing, the correlation between moisture retention and skin texture was analyzed and investigated for moisturizing products. The results show that skin texture parameters show negative correlation with the moisture content of stratum corneum and the skin oil content. That is, increasing the moisture content of stratum corneum and the skin oil content can reduce skin texture to some extent. Consumers are able to feel that the moisture retention of products is negatively correlated with the skin texture parameters obtained by instrument test. This work shows that the random double-blind control experiment can objectively reflect the correlation between moisturizing of cosmetics and skin texture.
