PDT emits light of a specific wavelength, penetrates the surface of the skin and converts the light energy into intracellular energy, accelerating cell growth process, increases blood circulation, and 2nd stimulate fibroblasts to produce collagen.
 
Treat Acne, wrinkles, increase skin elasticity and restore skin vitality. It has been proven to be effective for the treatment of various aspects of aging of the skin.
 
Working principle of best led light therapy device:
Bio-Light Therapy ls the Interaction of light, delivered through Light Emitting Diodes (LEDs),to cause bio stimulation on cell receptors. Blo-Light therapy encourages natural cell renewal and healing. By stimulating these actions, damage caused by the sun, the environment natural aging
and other external factors can be safely and painlessly remedied. Various studies around the world suggest that Blo-Light Therapy stimulates blood and lymph circulation and can decreases inflammation.
 
The principle of light waves:  LED colorful photodynamic skin beauty instrument, 7 different wavelengths of red, blue, purple, yellow, green, cyan and white light can treat various skin problems.
 
650nm Red light can enhance the cells activity, promote cells metabolism, make skin excrete large number of collagen protein and fiber tissue to fill on their own; accelerate blood  circulation, increase skin elasticity. Accelerate blood circulation, activate skin tissues, repair damaged skin, sensitive  skin and reduce wrinkles ,tighten pore, and proliferate collagen protein.
 
417nm Blu-ray Blue light wavelength acts on the skin surface kills bacterium directly and does not damage any skin tissue and reduce acne.
 
1055nm Purple light is anti-inflammatory. Renews skin, reduce wrinkles, especially useful in treating and repairing acne and acne-scars. accelerate the exfoliation of aging skin.
 
1171nm Yellow light It uses wavelength enhances blood circulation, activating cells, stimulate the cell excitability active role. Increasing the skin collagen fiber and elastic fibers that cause skin redness.
 
535nm Green light Wavelength can balance skin oil secretion, balance the proportion of water and oil and is a healing light.
 
500nm Blue light Enhance the energy of new cells in order ,with a good effect on  metabolism, balance secretion of oils and calm the skin.  Strengthen the ability to protect of skin itself. Calm down, release stress, and aid with sunburn.
 
1586nm White light penetrates the deep layer of the skin, accelerates the metabolism of active tissues.
