Visioscan® VC 98 - Skin Topography directly from the Skin

Visioscan Quadrat

The Visioscan® VC 98 is a unique UVA-light video camera with high resolution to study the skin surface directly. The images show the structure of the skin and the level of dryness very impressively but it can also be used on spots or hair and scalp. With its multi-functional software, the Visioscan® VC 98 is a very flexible system to characterize skin surface condition easily, accurately and very economically.

The Measurement Principle

Visioscan principleThe camera features a high resolution b/w video sensor and a ring shaped UV-A light source (proven to present no hazard to normal human skin) for uniform illumination of the skin. The camera can be connected directly to the USB port of your computer. The pictures are displayed in 256 grey levels. Wrinkles appear dark in the image; scaliness is shown in bright pixels. The software calculates a variety of interesting parameters on the images.



Advantages of the Visioscan®-Camera

  •  The special UV-light gives a very sharp and non-glossy high resolution image.
  • Stable connection by USB directly to the computer.
  • Pigmentation under the skin surface can be shown very well.
  • Small, easy to handle device for all kind of applications.
  • The extremely economic system can easily compete with the more expensive, complex devices.
  • 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 vc kreis linienimmediately. 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 %.
  • Ageing parameters as anisotropy (directionality of the lines) and corner density (density of the line crossing) are to your disposal.

  • Evaluation of desquamation (scaliness/dryness) of the skin with the foil Corneofix® F 20. A desquamation index is calculated.
  • Determination of sebum production with the foil Sebufix® F 16. The sebum production of each sebum gland can be monitored in real time on the screen.
  • Additional interesting functions e.g. hair length measurement after shaving or length measurements on lesions possible.
  • The Visioscan® VC 98 USBcan be used together with the Skin-Visiometer® SV 700 USB as combination instrument.
  • Worldwide established method with a variety of interesting studies. The Visioscan® has even repeatedly been used on ISS space missions.VC 3D

Additional Software Benefits:

  • All results can be stored, printed out together with the images and exported to spreadsheets (Microsoft Excel®).
  • Easy and quick calibration of the system in mm (x and y direction) is possible at any time.
  • A macro function allows the analysis of many images at the same time.
  • A coloured 3D image can be displayed quickly. Other displays of the image (e.g. relief, false colour, etc.) are possible.

Fields of Applications:

lab vcThe applications of this flexible tool are without limitation.

  • The Visioscan® is indispensable for efficacy testing and claim support for cosmetics, pharmaceuticals and detergents especially in regards to roughness and skin surface topology.
  • Dermatological basic research
  • Occupational medicine: to monitor the state of the skin and show the importance of skin protection products
  • many other applications
