Used a handful of times. Works flawlessly. All original accessories included. 2 LED wavelengths: THE RED LIGHT (620-730 nm Wavelength) The red light penetrates to 8-10mm and is best for fine lines and large pores. The red light stimulates collagen, an essential protein necessary for maintaining healthy, soft and beautiful skin. Collagen production is boosted, while damaged tissue is repaired. Enlarged pores look smaller and less visible! Beauty note: You’ll see the brightness more than feeling the heat of the lights. THE BLUE LIGHT (430-450 nm Wavelength) The blue light penetrates to 0.5mm and is best for acne-prone or sensitive skin. The blue light acts as an anti-inflammatory and calms hypersensitive, blemish-prone skin. Redness is minimized while acne-causing bacteria are also diminished. You’ll notice existing blemishes seem to immediately shrink, while skin stays breakout-free for longer! NIR - near infra-red light How does it work? The NIR procedure uses a safe level of infrared light that is able to penetrate the deeper layers of skin. The light energy heats the water in the skin tissue and causes collagen fibers to contract and tighten. It also stimulates fibroblasts to repair skin cells and produce new collagen. - Stimulates white blood cell production. - Promotes cell regeneration - Reduces inflammation - Improves circulation
