Cells that are damaged and poorly oxygenated as a result of inflammation, swelling, or trauma have been shown to have a significantly higher response to laser therapy than normal healthy cells. At a cellular level, there are photoreceptors that, when stimulated by deep penetrating photons, activate a biochemical cascade of events resulting in increased DNA/RNA synthesis and cellular proliferation. The product of these reactions is rapid regeneration, normalization, and healing of damaged cellular tissue. Photonic stimulation is the trigger for these metabolic changes.
