BENEFIT OF 660nm AND 850nm
660nm and 850nm are the human body’s optical window, which means these wavelengths have the ability to penetrate the skin, and soft hard tissue and are proven in clinical trials to have a good effect on pain, inflammation, and tissue repair.

The 660nm and 850nm wavelengths are chosen because these 2 wavelengths can act on different depths of the cortex, which means they have therapeutic effects for different skin layers. This is a unique feature compared to other similar products with different wavelengths.

Notes: Each led diode inside with dual wavelength at 1 pcs 660nm &1 pcs 850nm. Kindly noted that near infrared LED is invisible to the naked eye.
