The efficacy of both red light therapy systems relies on exposing bare skin to the light, as clothing prevents the light from deeply penetrating into our tissues. Many people feel uncomfortable standing for 20 minutes bare naked in front of the panel.
Another point of functionality is how these devices are being used. WIth panels, manufacturers usually recommend a distance between 6-12 inches. Since the lights are not fixed to your body, one has to stand in front of the device.
Consistency is one of the most important variables to the effectiveness of red light therapy when it comes to pain relief, so ease of use should be a major criteria for consideration.
In that regard, panels have shown to be rather impractical as they don’t fit seamlessly into people’s lifestyle. One has to actively make time for a therapy session, which is why most panels end up collecting dust after a while.
