Abstract: Various possibilities of laser application in skin diagnosis are overviewed. The method of determination of skin state through measuring the scattering properties of the tissue is proposed. The scattering coefficient of biological tissue depends on many uncontrollable factors, which include the concentration of interstitial water, the density of structural fibers, and the shapes and sizes of cellular structures. A spatially resolved two fibers measuring system of back reflectance at 830 nm was used. Immersion and temperature treatment are used as a controlling parameters of the skin under study. !6
