K4005-Comfytemp Red Light Therapy Pad for Neck and Shoulder
A:
This product has a default timer setting and will shut down after 20 minutes.
You can restart the device for further use. However, we do not recommend using it multiple times on the same body part. According to scientific evidence, longer usage does not necessarily yield better results, scientific evidence indicates diminishing returns. It's sufficient for 20 minutes; prolonged use increases the likelihood of cellular dehydration.
A:
This is normal. In the NIR mode, the lights emit 850nm near-infrared light, which is invisible to the naked eyes. Therefore, it's not that the lights are not on, it's just that our eyes cannot perceive this wavelength.
You can confirm the device is working by checking the mode indicator light on the button or by feeling the gentle warmth during use.
A:
Red light therapy works through two mechanisms: photobiomodulation and thermal effects.
●Photobiomodulation: This primarily stimulates mitochondria within cells, accelerating cellular metabolism, enhancing cellular activity, and promoting collagen production in the skin. These effects take time to become noticeable.
●Thermal Effects: The warmth generated by red light therapy is felt immediately. Unlike heating pads, which primarily heat the skin's surface, the heat from red light penetrates deeper into the body.
Extensive scientific research shows that using the device for 20 minutes daily can deliver visible results in as little as three weeks.
A:
Please first ensure the power connection is secure, then try pressing the power button to turn it on.
