This is the therapy light used by aestheticians to diminish the appearance of fine lines, wrinkles, and enlarged pores. Based on healing light therapy developed by NASA, the device has 24 LEDs that emit four pulsating wavelengths of infrared light to stimulate the production of collagen and cell growth, resulting in smoother, younger-looking skin. The light therapy facilitates blood circulation to increase elastin cell production, reducing blemishes and resulting in softer skin. The non-thermal light promotes healing by helping skin recover from sun damage and age spots. About the size of an electric toothbrush, the handheld light is easy to maneuver and hold near the face. Plugs into AC. 7" L x 1 1/2" W x 2 1/4" D.
