Medical lasers use an intense beam of light to lighten or completely remove your tattoo. Different wavelengths of light treat different colors of ink. When the ink particles of your tattoo absorb the light from the laser, they are broken up into tiny fragments. These fragments are then absorbed through your body's natural cleansing mechanism. This cleansing process generally takes a few weeks. Larger ink particles may require multiple treatments. With 4 different lasers (Discovery Pico, RevLite SI, Trivantage 755, Quanta Q+C,), Doctor Ink Eraser treats all ink colors with a variety of wavelengths and alternate between Nanosecond and Picosecond emission modes to get the fastest, most impressive results possible!
