SKIN-SUBSTITUTIVE MEMBRANE, METAL MOLD, AND METHOD OF EVALUATING AGENT FOR EXTERNAL APPLICATION ONTO SKIN
摘要
<p>A skin-substitutive membrane includes one surface on which a groove-like recessed part having a cross section of chamfered V-shape and a flat surface part. The arithmetic average roughness (Sa) of the one surface is 10 to 50 µm, and the recessed parts is 50 to 500 µm in width, 30 to 150 µm in depth, and 50 to 100% in spectral transmissivity of a light having a wavelength of 290 to 400 nm.</p>
