How does light emitting diodes stimulate wound healing at a cellular level?

Light-emitting diodes (LEDs) stimulate wound healing at the cellular level primarily through photobiomodulation, which involves the absorption of light by mitochondrial chromophores. This process enhances ATP production, leading to increased energy availability for cellular processes. It also promotes the release of growth factors and cytokines, which facilitate tissue repair and regeneration. Additionally, LED therapy can reduce inflammation and enhance collagen synthesis, further supporting the healing process.
