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 impressively the structure of the skin and images of hair & scalp. With its multi-functional software, the Visioscan® VC 20plus is a very flexible system to characterize skin surface, hair and scalp condition easily, accurately and very economically. It had been used on board of the International Space Station ISS for several years.
