LED light therapy, particularly in the red and near-infrared wavelengths, penetrates the skin and is absorbed by the mitochondria, the energy-producing centers of cells. This absorption enhances cellular metabolism, leading to an increase in adenosine triphosphate (ATP) production. ATP is essential for cellular function and plays a crucial role in the energy needed for the healing process.

LED light therapy stimulates fibroblasts, which are cells responsible for synthesizing collagen, a key structural protein in the skin. The increased production of collagen is vital for the formation of new tissue and the strengthening of the wound site.

LED light therapy has anti-inflammatory effects, helping to mitigate the inflammatory response associated with wounds. By reducing inflammation, the therapy promotes a more conducive environment for healing.

Light therapy improves blood flow by promoting the formation of new blood vessels (angiogenesis). Improved circulation ensures a more efficient delivery of oxygen and nutrients to the wound site, facilitating the healing process.

LED light therapy has been reported to have analgesic effects, providing relief from pain associated with wounds. This can contribute to an improved overall experience for individuals undergoing the healing process.

Certain wavelengths of LED light, particularly blue light, possess antimicrobial properties. This can help reduce the risk of infection in wounds by targeting and inhibiting the growth of bacteria.
