Information on Laser Therapy

How does laser therapy work?

Therapeutic lasers operate in the wavelength range of 600–1064 nm (red to near-infrared light). The photons are absorbed by chromophores in the mitochondria, where they stimulate ATP production, modulate inflammatory mediators, and promote tissue regeneration. This effect is known as photobiomodulation (PBM).
