Commentary: Effects of Long-Pulsed 1,064-nm Neodymium-Doped Yttrium Aluminum Garnet Laser Therapy on Dermal Collagen Remodeling

Abstract

There is an ever-expanding body of clinically oriented literature that demonstrates the efficacy of photorejuvenation as a means of enhancing the appearance of skin. From traditional fully ablative laser resurfacing to nonablative laser therapy to fractionated photothermolysis, there is substantial evidence of efficacy, including a number of randomized, controlled trials. There have also been several attempts to objectively measure the effects of laser therapy using tools such as ultrasoundbased imaging, profilometry, histology, and threedimensional imaging.
