Comparison of the Q-switched alexandrite, Nd:YAG, and ruby lasers in treating blue-black tattoos.

Abstract

A new generation of highly selective short-pulsed lasers has emerged in recent years for the treatment of tattoos. Several studies (including reports by the present investigators) have proven the efficacy of each of the three commercially available, FDA approved devices; namely, the Q-switched alexandrite, Q-switched Nd:YAG and Q-switched ruby lasers. Considerable differences among the three have been reported in relation to the rate of clearing of the tattoo ink particles, tissue effects, beam profile, wound healing, and side effects.
