Photon therapy
The theoretical basis of the photon therapy is that biological tissues absorb the light energy and transfer light energy into heat and chemical energy, resulting in a series of chain reactions of human body, there are four types: light-induced decomposition, light-induced oxidation, light-induced polymerization and light-induced sensitization. Different wavelength of light have different biological effects:
1. 405nm Blue light to eliminate acne inflammation: Antibacterial,anti-inflammator, renewal, inhibit sebum secretion, has anti-aging effects,make the skin soft, smooth, white and charming.
2. 633nm Red light high-energy narrow-band, speed up healing: make human muscle and skin cells grow 5 times more than the normal rate, increase endurance and resistance to fatigue, promote cell metabolism.
3. 590nm±5nm Yellow light will give energy for the skin, improve immunity ability for the skin.
4. 560nm±5nm Green light is used to relax the skin, let the patient get relaxed from hard work.
