How does the Plasmalite® technology work?
The basic principle of photo-rejuvenation and hair removal is selective photo-thermolysis, i.e. selective heating of the unwanted skin lesions/hair follicles to various temperatures depending on the type of the lesion - without any damage to the surrounding skin.
Plasmalite ® is the latest technology for selective photo-thermolysis in aesthetic treatments, which is based on a unique combination of patented fluorescent filter technology, selected spectrums of light source emission, pulse forming and sapphire based skin-cooling system.
It operates through creation of a directed incoherent light beam of spectrally balanced bandwidth. The light is spectrally filtered to remove the shorter wavelength portions (UV) most likely to cause harm to the skin. A sapphire crystal light guide is used to transport the resultant longer wavelength light to a laser-dye impregnated polymer sheet, which emits the selected wavelength band.
Incorporating all the benefits of both laser and Intense Pulsed Light in a single system, Plasmalite ® offers non-invasive, safe and effective method for skin rejuvenation and hair removal. |

How does Plasmalite® rejuvenate skin and treat skin conditions?
Plasmalite uses filtered light to selectively target the melanin, haemoglobin and collagen by selective photo-thermolysis. A sapphire crystal wave-guide conducts the filtered light to the target chromophores in the tissues. The excessive potentially harmful heat that is generated in the epidermis is efficiently removed into the sapphire crystal due to its direct contact with the skin and high speed of heat removal (30 times compared to water or gel).
Clinical studies have shown that selective heating of the dermal collagen layer to a temperature of about 60°C stimulates the fibroblasts to produce new collagen. The increase in collagen production takes place during a period of 8-10 weeks and lasts for 6-12 months after the last treatment. The biological mechanism of photo-thermal collagen stimulation is not yet fully explained, but it is believed to be similar to the mechanism of wound healing after selective activation of the fibroblasts. A large number of clinical trials have proven that the method efficiently flattens wrinkles by increasing the thickness of the collagen layer.
Vascular lesions can be treated through selective absorption of the light by the haemoglobin at a wavelength band starting from selected 535 - 615 nm and from that cut on wavelength up to about 1000 nm. When the temperature reaches about 60-65°C the blood coagulates and the inner cells of the intermediate sized blood vessel denature causing the vessel to coagulate and collapse. In contrary to many short-pulsed laser, Plasmalite with its Long Pulsed Light does not cause purpura in the treated area. Purpra arises after rupture of the micro vessels due to rapid heating. This is a typical side effect experienced with short pulsed laser.
The broadband spectrum of Plasmalite generates a homogenous heating throughout the lesions, while the single wavelength lasers produce inhomogeneous heating, since the monochromatic light has a fixed absorption depth for a specific chromophore. |
