The main difference betweenLED devicesand the coherent light from the LYMA laser is that the laser light is more deeply penetrative and doesn’t lose energy with penetration like non coherent light. This means it’s able to have different physiological effects at a deeper penetration, so you’re still able to induce physiological effects all the way through the dermis as the laser does not loose efficacy as it penetrates through the layers.
