The majority of tattoo removal practitioners make use of an Nd: YAG laser, which includes the Astanza Duality as it is capable of producing the most versatile wavelengths used for the removal of unwanted tattoos. However, enlighten and PICO are quickly becoming more and more popular, as it is the first system on the market that makes use of both PICO and NANO pulses for effective and safe tattoo removal. Given that tattoos are typically made up of multiple colors that will require multiple wavelengths to remove effectively, the enlighten makes use of three fully-integrated laser wavelengths (532 nm, 1064 nm, and 670 nm) which include the first true red wavelength in the picosecond domain. The unique wavelength allows for the shattering of congenital or resistant pigments or inks in the skin, addressing even the most difficult tattoos crafted with blue and green inks.
