Synchro Replay is a combination of the Nd:YAG and Alexandrite wavelengths which are universally recognized as the most effective laser source in removing hair. Physicians from around the world acknowledge that Alexandrite is efficacious at hair removal in clients with fair skins while the Nd:YAG laser is most used in the treatment of dark skins. With these two laser sources combined, the Synchro Replay offers a wide range of treatments for hair removal. Its FT pulsed light handpiece can be used when treating extended areas. The treatment time speeds up when a larger treatment surface is used, especially during some particular combinations of hair color and phototype is used.
