The technology
How laser tattoo removal works
A tattoo laser delivers a very short pulse of light at a wavelength the ink absorbs. The pulse breaks the pigment into smaller fragments, which the body clears gradually over the following weeks. Because ink sits at different depths and colors absorb different wavelengths, removal takes a course of sessions rather than one visit.
Q-switched vs. picosecond
Q-switched Nd:YAG lasers deliver nanosecond pulses and are the established workhorse for black and dark inks. Picosecond lasers deliver pulses roughly a thousand times shorter, which shatters pigment more mechanically and with less heat. Manufacturers position picosecond systems for stubborn pigment, color work and shorter treatment courses. In this collection, the Shape Tactics Mini ND YAG and NDPlus are Nd:YAG systems, and the Winkonlaser EL400, EL500, EL900 and Picoking II are sold as picosecond platforms.
What else these lasers treat
With the right wavelength and handpiece, the same machine can treat pigmented lesions such as sunspots, freckles and age spots, and some models support carbon peel or skin rejuvenation protocols. Check the product page for the applications the manufacturer lists for each model.
