Discover how Red Light Therapy transformed one person's battle with chronic arthritis pain. Learn about the science behind photobiomodulation and how it can provide natural, drug-free relief for osteoarthritis, rheumatoid arthritis, and other inflammatory conditions.

The penetration depth of light in biological tissues is a complex topic, influenced by wavelength, power, tissue type, and even individual variations. The values below are general approximations for therapeutic light (LEDs or low-level lasers) and assume reasonable power output. Important Considerations: Absorption by Chromophores: Different molecules in the body (chromophores) absorb light at specific wavelengths. Melanin (skin pigment), hemoglobin (in blood), and water are major chromophores that influence penetration. Scattering: Light can be scattered as it passes through tissue, which reduces its effective depth. Longer wavelengths tend to scatter less than shorter ones. Effective Depth vs. Total Penetration: While...
