Working principle: Energy emitted by the system has a strong penetration ability which allows it to reach the deep layer of dermis. The pigment particles absorb the light energy and explode sharply, burst into the tiny pieces, thus diminish the color density and get rid of it.So the appliance can effectively do away with mutant pigmentations and vascular tissue based on undamaged ambient tissue. This is called â??Selective heat absorptionâ?? principle in medical field. Advantages: 1. Safe way to remove unwanted tattoos. 2. Effective treatment for dark tattoo inks (black, blue and green). 3. Dramatic results after several treatments. 4. Painless treatment, no injury to skin and hair follicle, no risk of scarring, no side-effect. 5. Adjustable spot size an frequency. 6.
