How Does PDT Light Work
LED Skin Rejuvenation is the interaction of light, delivered through Light Emitting Diodes (LEDs), to activate cell receptors causing them to produce collagen or multiply. One of the original applications for LEDs was PhotoDynamic Therapy (PDT), using photo-activated creams for the treatment of actinic keratosis and pre-cancerous lesions. 
LED offer a totally natural, non-ablative method for skin rejuvenation. The light from the LEDs interacts with cells and
stimulates them to produce new collagen and elastin. Studies confirm that the same LED energy can be used to inhibit collagen formation, which can be helpful in the treatment of scars. By manipulating the wavelengths, cells can be turned on and off. Yellow light LEDs are used for photo-rejuvenation. Blue light LEDs are used in the treatment of acne. Red light LEDs are used for PhotoDynamic therapy.
