The desire to remove tattoos has probably been around as long as their existence. Recent technological advances in lasers have finally made it possible to remove tattoos without leaving an equally undesirable scar.
The purpose of this article is to review the use of the Q-switched ruby (694 nm) and the Q-switched Nd:YAG (532 and 1064 nm) lasers for effective removal of tattoo ink, with cosmetically appealing results.
The Q-switched ruby laser (694 nm) effectively removes blue-black and green ink, may treat other colors less efficiently, and is frequently associated with transient pigmentary changes, including rare depigmentation. The Q-switched Nd:YAG laser at 1064 nm quickly removes black ink, as well as other colors less efficiently; pigmentary changes are much less frequent, correlating with its lower absorption by melanin. The 532-nm wavelength treats red ink effectively, but also leads to temporary hypopigmentation. Transient textural changes may be noted at all three wavelengths discussed, but scarring is rare.
Q-switched lasers can remove tattoos without residual scarring. Efficacy of ink removal is dependent on the wavelength used for the targeted pigment.
去除纹身的愿望可能自纹身存在以来就已存在。激光技术的最新进展最终使得去除纹身而不留下同样令人不满意的疤痕成为可能。
本文的目的是综述调Q红宝石激光（694nm）和调Q钕：钇铝石榴石激光（532nm和1064nm）在有效去除纹身色素方面的应用，以获得具有美容效果的结果。
调Q红宝石激光（694nm）能有效去除蓝黑色和绿色色素，对其他颜色的去除效果可能较差，且常伴有短暂的色素变化，包括罕见的色素脱失。1064nm的调Q钕：钇铝石榴石激光能快速去除黑色色素，对其他颜色的去除效果较差；色素变化的频率要低得多，这与其对黑色素的低吸收率相关。532nm波长能有效去除红色色素，但也会导致暂时性色素减退。在所讨论的所有三个波长下都可能出现短暂的质地变化，但疤痕形成罕见。
调Q激光可以去除纹身而不留下残留疤痕。色素去除的效果取决于用于靶向色素的波长。
