| Theory of PDT (Photo Dynamic Technology) As the most advanced technology, PDT beauty system uses America original LED photobiology with the purity of 99% light acts on the target skin tissues to raise the activity of cell and improve the metabolism. No thermal effect, no injury and discomfort on the skin, which is not available for traditional skin care products. PDT (Photo Dynamic Technology) Red light: the red light is absorbed selectively by the pigments and blood vessel can reach the result of skin rejuvenation, whitening, speckle and vascular removing, reducing acne and recovering the injured skin. Blue light: the blue light can inhibit the inflammation, kill acne bacillus so as to eliminate acne of the skin. Mixed light (both red and blue light): the mix light of red and blue can improve the microcirculation to irritate the fabric cellular to enhance collagen and elastic fibers production, reconstruct the dermis collagen fabric structure, eliminate fine winkles, enhance stretch facial skin and effectively alleviate symptom of laxity so as to change the roughness dark tone of facial skin.
