Many beauty salons and clinics prefer diode laser hair removal instead of SHR or IPL, although they each has their own advantages, and most of them also have independent ND YAG laser tattoo removal machine. When these beauty salons expanded their business and wanted to buy more diode lasers and nd yag lasers, they found that the combination of diode laser machine and Nd YAG laser is more cost-effective. So most of them will give up buying separate diode lasers and separate nd yag lasers, and choose 2-in-1 diode lasers and nd yag lasers.
