Article introduces the method of transmission profilometry based on the absorption of parallel light after penetration of skin imprint. The imprint is made by a special procedure from a blue silicone to a standardized form. The light is detected by a CCD camera and the obtained values are evaluated by a specific software. The output curves and numbers which evaluate the roughness also provide two- or three-dimensional pictures. The method tolerably enables to statistically evaluate quantitative and qualitative changes of skin surface and thus objectively assess various physiological or pathological phenomena or treatment procedures.
