Skin-Visiometer® SV 700 USB
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.
The Measuring Principle
The replica is made out of a special blue 2 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.
Thus 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.
Advantages of the Skin-Visiometer®
sebum production can be evaluated.
(Surface Evaluation of the Living Skin) is also a useful addition to the system.
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-wrinkle products.
