ABSTRACT
Q-switched 1064 nm/532 nm Nd: YAG Lasers present important characteristics which can contribute toward the removal of tattoos, for having the ability to reach only specific targets with minimal damage to the tissue. Despite reports of their clinical benefits, only a few scientific studies demonstrate the efficacy and safety of these types of lasers in the short and long term. To substantiate the effects, benefits, and safety of the application of Q-switched 1064 nm/532 nm Nd: YAG lasers, a systematic review was carried out from September to December of 2019, about the studies which report their use in the removal of tattoos, published in the last 20 years. Randomized clinical trials in humans were considered, as long as they evaluated the efficacy, safety, and benefits of the application of Q-switched 1064 nm/532 nm Nd: YAG lasers in the removal of black and color tattoos in different skin phototypes. One hundred and twenty-two articles were identified after the titles, abstracts were read, and duplicates were removed; six articles were left, which were included in the research (188 individuals). The Q-switched 1064 nm/532 nm Nd: YAG lasers seem promising in the short term, with minimal adverse effects; however, the efficacy and safety in the long term still present limitations. Consequently, future research is necessary, with better methodological standardization applied and with a follow-up for a longer period of evaluation of possible permanent adverse effects, to determine the standardization and safety of the therapy with the lasers Nd: YAG de 1064 nm/532 nm Q-switched.
