  • he Biophotonic Scanner is the world’s first measurement device to determine Carotenoid Value in the Skin (SCS) – an instant recording of carotenoid antioxidant activity in your body. By simply placing your hand in front of a faint blue light, you can get your Carotenoid Value in your skin within minutes. The Pharmanex® Biophotonic Scanner Technology is based on an optical method known as Raman Resonance Spectroscopy. This technology has been awarded the Nobel Prize and is used for biological measurements, as well as scientific discipline supported by years of research. Thanks to Pharmanex, technology is now available to everyone. The scanner uses optical signals to measure carotenoid levels in human tissue just below the skin’s surface. These signals identify the specific molecular structure of carotenoids. Pharmanex® is the exclusive holder of the patented Biophotonic Scanner technology. The scanner was developed by physicians and physicists at the top university in the United States
