Presently there are several lasers which can be used for non-ablative skin rejuvenation. They can be broadly divided into two groups. Some of these are lasers traditionally used for the removal of skin pigment or blood vessels e.g. Q-switched Nd:YAG laser and pulsed dye laser.
The second group consists of lasers which are specifically manufactured for the sole purpose of non-ablative laser procedure by stimulating collagen synthesis e.g. 1320 nm Nd:YAG laser (Cool Touch), 1450 nm diode laser (Smooth Beam), 1540 nm erbium-glass laser (Aramis) and the long pulsed 1064 nm Nd:YAG laser (Vantage).
