The photostimulation consists of exposing programmed to a source of artificial light with high intensity and of different wavelengths (color). Depending on the color of the light, the interaction between light photons and cellular receptors modulates a biological response of tissues that trigger a process called photo-bio modulation. This activity has a positive influence psycho-physical balance of the individual treated and improves the regenerative and reparative processes. The photostimulation produces no side effects and has no particular contraindications.
