The ND YAG 1064 laser is an excellent wavelength to deliver a
thermal stimulus within the dermis, and thus initiate new collagen
formation, both because of the depth of penetration of the wavelength
itself and the low melanin absorption. The goal is to maintain as much
heat as possible in the skin to stimulate not only collagen
contraction, but also collagen remodeling as well.
The Gentle YAG's ability to treat skin tightening is also due in part
to its patented epidermal cooling system, the Dynamic Cooling Device
TM. There are multiple noninvasive technologies available today to
address the issue of skin laxity, non-surgical tissue tightening has
been shown to be both effective and an acceptable alternative to
surgery for many individuals.
While no one laser can "do it all," it has been suggested that the YAG
laser comes pretty close. It delivers fast performance, versatility for
skin tightening, and wrinkle reduction.
