Skin topography system Visioscan® VC 20plus

The Visioscan® VC 20plus is a unique UVA-light video camera with high resolution to study the skin surface directly. The SELS® parameters (Surface Evaluation of the Living Skin) have been developed especially for this camera and are used in numerous studies. The images show the structure of the skin and the level of dryness very impressively. The camera can be used on pigmented spots and lesions and on hair. With its multi-functional software, the Visioscan® VC 20plus is a very flexible system to characterize skin surface condition easily, accurately and very economically. It had been used on board of the International Space Station ISS for several years. The latest Visioscan® generation with improved hard- and software offer a multitude of possibilities: The evaluation method SELS® (Surface Evaluation of the Living Skin - developed by the Institute for Experimental Dermatology, Prof. Tronnier, University of Witten-Herdecke, Germany) analyses the grey level distribution and allows the calculation of four clinical parameters to quantitatively and qualitatively describe the skin surface as an index: Skin smoothness (Sesm), Skin roughness (Ser), Scaliness (Sesc), Wrinkles (Sew). In addition to the valuable SELS® calculations also other interesting parameters can be calculated: lines can be drawn on the images and the profile and the results are shown immediately. Roughness indices for up to 180 lines arranged vertically, horizontally or circularly are immediately available. Special parameters have been created to describe virtually the skin topography volume (mm²) and unfolded surface in %.
