For targeted areas, we suggest to use the red light panels, 20-30 minutes per session. For lung or heart problems, red light therapy is not typically recommended as the primary treatment modality. However, some studies have suggested potential benefits of red light therapy for improving circulation and promoting healing in these areas. Again, the usage should be guided by a healthcare provider, and the duration and frequency of treatment will depend on the individual case.

For red light at 630nm to 660nm:

In general, red light wavelengths in the range of 630 to 660 nm have been shown to penetrate relatively deeply into the skin, reaching depths of several millimeters. However, the exact depth of penetration can vary depending on the factors mentioned above. For example, darker skin types with higher melanin content may absorb red light more strongly, limiting its penetration depth. In terms of biological effects, red light therapy is thought to stimulate mitochondrial function, promote blood flow, and enhance cellular metabolism. These effects are generally believed to be most pronounced in the superficial layers of the skin and underlying tissues.

For NIR light at 810-850nm:

Near-infrared light, including 850nm, has been shown to penetrate deeper into tissues than visible light wavelengths. However, the exact depth of penetration can vary depending on the factors mentioned above. For example, darker skin types with higher melanin content may absorb near-infrared light more strongly, limiting its penetration depth.

In terms of biological effects, near-infrared light therapy is thought to promote blood flow, enhance mitochondrial function, and have anti-inflammatory effects. These effects are generally believed to be more pronounced in deeper tissues compared to visible light wavelengths.

Additionally, it’s worth mentioning that near-infrared light, including 850nm, is often used in various medical and therapeutic applications, such as wound healing, pain relief, and skin rejuvenation.

We suggest to wear eye patch, or at least keep your eyes closed when red and NIR light exposing directly our face.
