FRACTAT™
When a Q-switched laser pulse strikes the tattoo pigment, the heat given off generates gas and steam within the skin. This has several consequences.
Firstly, it causes an optical shielding or “frosting” effect that prevents any subsequent laser pulse from effectively reaching any deeper lying pigments.
Secondly, the gas bubbles which are formed around the pigment particles can damage the surrounding tissue.
To improve on the limitations of older Q-switched technology, Fotona developed the patented FracTat™ procedure. The first step involves drilling microscopic holes in the skin using a fractional ablative laser handpiece. The fractional micro holes act as pressure relief ducts through which the steam can escape without building up excessive pressure. The second step is the normal Q-switched laser tattoo treatment. The second step can be repeated several times as the steam shielding effect dissipates much more quickly.
