Move+ Pro doesn’t get hot, but you might feel your skin warm up a bit. The reason why your skin doesn’t get hot is because Move+ Pro uses high-frequency, low-level laser therapy that pulsates at the right frequency to deliver sufficient energy into your tissue without heating it up. FlexBEAM can get relatively warm, but not hot enough to feel uncomfortable or to cause burns. But to prevent the light modules from overheating, FlexBEAM has a dedicated fan on each of the LED banks.
