Update on lasers in facial plastic surgery.

[PURPOSE OF REVIEW] Since the theory of selective photothermolysis was described, the field of facial plastic surgery has advanced the science behind laser: tissue interactions. Particular advances in skin cooling, hair removal, intense pulsed light, and uses for aesthetic and nonaesthetic skin problems are described in this review.

[RECENT FINDINGS] Continued basic science research in lasers has led to improvements in current technology available to the facial plastic surgeon. Advances in skin cooling have allowed for wider use in all Fitzpatrick skin types without concomitant adverse reaction.

[SUMMARY] Our understanding of laser science continues to expand our knowledge in basic laser: tissue interaction. An improvement in various laser mediums and adjunctive devices provides the facial plastic surgeon with instruments to treat a wider patient population. The benefit is a successful clinical and aesthetic result with improved safety.
