Evolution of laser skin resurfacing: from scanning to fractional technology.

BACKGROUND: Laser skin resurfacing was popularized for photoaged and scarred skin 2 decades ago. Since then, several technologic advancements have led to a new generation of delivery systems that produce excellent clinical outcomes with reduced treatment risks and faster recovery times.

OBJECTIVES: To review the evolution of laser skin resurfacing from pulsed and scanned infrared laser technology to the latest techniques of nonablative and ablative fractional photothermolysis.

MATERIALS AND METHODS: All published literature regarding laser skin resurfacing was analyzed and collated.

RESULTS: A comprehensive review of laser skin resurfacing was outlined and future developments in the field of fractionated laser skin treatment were introduced.

CONCLUSION: Laser skin resurfacing has evolved such that excellent clinical outcomes in photodamaged and scarred skin are achieved with rapid wound healing. As newer devices are developed, the applications of this technology will have a dramatic effect on the delivery of medical and aesthetic dermatology.
