Commentary: Effects of long-pulsed 1,064-nm neodymium-doped yttrium aluminum garnet laser therapy on dermal collagen remodeling.

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.
