How does Low Level Laser Therapy work?
LLLT is NOT a heat therapy – the effects are mediated by light. This is a photochemical effect that induces a chemical change within the cell that promotes healing.
Examples of other photochemical effects that are well known in medicine:
- the role of sunlight in Vitamin D synthesis
- the use of blue light to treat neonatal jaundice
- ultraviolet light to treat psoriasis
- ultraviolet light producing a suntan
LLLT works best in injured or “stressed” cells interrupting the inflammation pathway and helping to restore normal cell function and promote tissue repair.
Specifically, LLLT is absorbed by cytochrome c oxidase, an enzyme in mitochondria, the energy unit of the cell, causing a cascade of intracellular, extracellular and physiological changes.
