Clarity Pro takes photo images of a patient's skin in white light and then, with software, analyzes its health. Here it shows various forms of skin condition, including three different depictions of dry skin and its severity in white on the patient's face and in red in the graphs.
Technology known as flourescence spectroscopy, which shows the interaction of light within tissue, has long been used to find biochemical changes in the skin. Here it depicts damage from UV rays.
BrighTex Bio-Photonics uses facial-recognition and image-processing algorithms to develop coordinates for the face and then target analysis for specific areas.
