Proven Wavelengths
Wavelength is important because it determines whether it can penetrate the skin to interact with chromophores within cells. Chromophores, such as cytochrome c oxidase in mitochondria, have specific absorption ranges. These ranges correspond to precise wavelengths of light, which trigger biological processes when absorbed.
If the light’s wavelength does not align with the chromophore’s absorption range, the intended biochemical reaction will not occur. For example, cytochrome c oxidase absorbs red (around 660 nm) and near-infrared light (800-880 nm) to enhance ATP production. Using an unsuitable wavelength that falls out of this range would fail to activate this pathway, rendering the therapy ineffective.
What to look for:
- For a product to be classified as a medical device and registered with regulatory authorities, it must meet stringent standards and demonstrate clinically verified therapeutic benefits. Choosing registered devices ensures you are selecting a solution with proven efficacy and safety. Be cautious of devices with unclear origins or companies making exaggerated marketing claims without substantiation.
