发生在皮肤和玻璃垫之间的界面上的现象，或者在其表面移动，通过直接观察和记录由皮肤位移引起的垫上的力来测量。静态和动态摩擦系数是作为施加在垫上的载荷的函数来确定的。描述了一些应用于皮肤的美容治疗对摩擦系数记录的影响。结果表明，在滑动过程开始时，由于皮肤微救济的压缩和扭曲，出现了不连续现象。摩擦系数取决于施加在衬垫上的载荷。我们的研究证实了皮肤表面水化后摩擦系数的增加，并表明摩擦力振幅的波动可以提供一个客观的，尽管是间接的皮肤光滑度测量。
Phenomena occurring at the interface between skin and a glass pad, alternatively moved at its surface, are described by direct observation and measured by recording the force on the pad induced by the skin displacement. Static and dynamic friction coefficients are determined as a function of the load applied on the pad. Influence on the recordings of the friction coefficient of some cosmetic treatments applied on the skin are described. Results show that discontinuous phenomena, due to compression and distortion of the skin microrelief, occur during the beginning of the sliding process. Friction coefficients are depending on the load applied on the pad. Our studies confirm the increase of friction coefficient after hydration of the skin surface and suggest that the fluctuations in the frictional force amplitude could supply an objective, although indirect, measurement of skin smoothness.
