BACKGROUND/PURPOSE: One of the constantly developing fields in the area of cosmetology is the analysis of the efficacy of cosmetics products. Various instrumental techniques are available nowadays to evaluate changes in skin surface and measure anti-wrinkle activity. The aim of our study was to present and confront two methods of the analysis of skin surface, Primos and Visioscan, regarding their applicability in evaluating anti-wrinkle properties of cosmetic formulations and treatments.
The study was performed on women, taking part in anti-wrinkle cosmetic treatments. Various skin aging parameters were analyzed, including skin surface changes. The results obtained with Visioscan and Primos were compared regarding their usefulness in anti-wrinkling properties assessment.
The assessment of skin condition suggested anti-wrinkle properties of the applied cosmetic treatment. Both Visioscan and Primos analyses were consistent with each other and had similar faults as well.
The results of this study show that both complementary technologies (Visioscan and Primos) are appropriate for characterizing the skin surface and could be useful in testing the efficacy of anti-aging properties. There are some measurements which are unique to just one method, none, however, seems to be significantly more useful for efficacy testing than the other.
背景/目的：在美容领域，不断发展的领域之一是对化妆品功效的分析。如今，有各种仪器技术可用于评估皮肤表面的变化并测量抗皱活性。我们研究的目的是介绍和比较 Primos 和 Visioscan 两种皮肤表面分析方法，以评估它们在评估化妆品配方和治疗的抗皱性能方面的适用性。
该研究在参加抗皱化妆品治疗的女性中进行。分析了各种皮肤老化参数，包括皮肤表面变化。比较了 Visioscan 和 Primos 的结果，以评估它们在抗皱性能评估方面的有用性。
皮肤状况的评估表明，所应用的化妆品治疗具有抗皱特性。Visioscan 和 Primos 分析相互一致，也有相似的缺陷。
这项研究的结果表明，两种互补技术（Visioscan 和 Primos）都适合于描述皮肤表面特征，并且可用于测试抗衰老性能的功效。有些测量方法是一种方法特有的，但是，似乎没有一种方法比另一种方法更有助于功效测试。
