Instrumental Tests Using Visiofacequick / Miravex Antera 3D ™ Equipment
The VisioFaceQuick apparatus is a device designed to show the pictorial representation and analysis of the skin. These stacks have photographs taken in macro images before and after the application of the product within certain periods. These images are then evaluated in the software provided with the device. After the tested places or areas are determined, the program compares the default parameters and prepares a report that includes smoothing, wrinkles, pores, color delta T, delta E. Apparatus Miravex Antera 3D ™ is a device for analysis and evaluation of the skin. Results are prepared in 2D and 3D images and by spectral analysis of the skin. The rapid scan shows the color of the skin, its roughness, the depth of the wrinkles and the degree of sun damage. It allows you to see the effects of this process – smoothing, enhanced color after laser treatments, scrubbing, cream. The device measures the concentration of melanin and hemoglobin, which enables to accurately analyze the pigmentation of the skin and examine the length, width and depth of wrinkles. The survey allows you to specify skin redness / erythema, skin color / highlights, amount of pores, skin smoothing, depth and length of wrinkles.
