The Visioline ® VL650 is used for assessing the skin macro-relief using a replica and oblique lighting. It provides another excellent method for assessing the topography of the skin. It is a further development of the renowned Quantirides® system.
Where to use:
This method has been scientifically acknowledged and established for many years to analyse objectively the deeper lines and macro wrinkles such as crow feet. This is especially interesting for claim support of anti-aging and antiwrinkle products.
The measurement is based on shadows on a silicon replica. The replica, which is a negative of the skin surface, is illuminated uniformly with a defined light source mounted in a specified angle. The shadows visible on the replica created by the oblique light are captured with a high resolution, quick FireWire camera, which is mounted vertically to the replica. The sophisticated software analyses different characteristics of the wrinkle in real length and depth (in mm) and a shape factor.
