Assessing the Skin Micro Relief

The Skin-Visiometer® SV 700 USB is an established tool to evaluate the topography (micro relief) of the skin surface by light transmission of a very thin, special blue dyed silicone replica.


  • Advantages of the Skin-Visiometer®

    Visiometer arm replica
    • The very viscous two component silicone, mixed under vacuum to avoid bubbles, fills even smallest skin depths and reproduces them in detail
    • Replica can easily be taken around the world and afterwards analysed centrally in one place (ideal for multi centric studies or studies involving different ethnical groups).
    • The replica can be stored easily over long time periods.
    • Extremely quick and convenient connection to computer by USB
    • High resolution images
    • Worldwide established method to look at skin's micro relief with a broad range of studies
    • This special measurement method allows the calculation of various different skin parameters within one second.
    • Lines can be drawn on the images and the profile and the results are shown immediately.
    • The standard roughness parameters Rt, Rm, Rz, Rp and Ra for up to 180 lines arranged vertically, horizontally or circularly are immediately available.Visiometer software
    • Special parameters have been created to describe the skin topography volume (mm²) and unfolded surface in %.
    • Topographic information to quantify the direction of lines (anisotropy), intersection of lines and enclosed cells as reliable aging parameters
    • A coloured 3D image can be displayed quickly. Other displays of the image (e.g. relief, false colour, etc.) are possible
    • All results can be stored, then printed out together with the images and are automatically available for spreadsheet analysis (e.g. Excel®)
    • Easy and quick calibration of the system is possible at any time
    • A macro function allows the analysis of many replicas at the same time
    • With the foils Corneofix® F 20 and Sebufix® F 16 desquamation and sebum production can be Visiometer 3Devaluated

    The skin camera Visioscan® VC20 plus with its analysing software SELS (Surface Evaluation of the Living Skin) is also a useful addition to the system.

  • Measurement Principle

    Visiometer principle e

    The replica is made out of a special blue two-component silicone and then is placed between a parallel light source and a b/w CMOS-camera. The light is absorbed according to the thickness of the silicone material. The absorption rate of the blue pigments is known. The replica reproduces the heights and depths of the skin as a negative, i.e. wrinkles are higher in the replica as the silicone is thicker in this place. The amount of absorbed light is calculated by Lambert and Beer's Law: Φex = Φin • e-kd

    The outgoing light is proportional to the incoming light, the thickness of the material and the material constant k.

    VisiometerThus a digital image in 256 grey levels can be created of which the 3 dimensional coordinates are known for each single pixel. Many interesting parameters can be measured in μm.

  • Fields of Application

    The measurement of the depth of the skin micro relief has been a moist interesting subject to the cosmetic industry for decades. The Skin-Visiometer® SV 700 is an exact, easy to use, most economical tool for the R&D laboratories or the test institutes for formulation and efficacy testing of anti-aging products.

    Typical claims substantiated with the Skin-Visiometer®: structure/surface improving, against fine lines and wrinkles, anti-aging, smoothing, anti-roughness and more.
