The PicoWay laser only targets pigment, in this case tattooed areas, so the surrounding skin is not damaged during the treatment. In addition, much less heat is generated than with conventional lasers, since the Picoway with its picoseconds mostly works with a photoacoustic effect and not with a thermal effect. This guarantees a safe treatment with fewer side effects. After the treatments, the skin may become discolored or there may be redness around the treatment site. A transient lightening of the skin may also be seen in some patients. However, this will usually normalize after a while.
