K4025-Comfytemp Portable 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:
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.
By checking the indicator light in the battery case, we can observe that it is still on, indicating that the device is still active. Additionally, after using this mode for a while, one can feel the heat generated by the device.
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 device is fully charged, then try pressing the power button to turn it on.
