Photothermal therapy using gold nanoparticles and a long-pulsed 755-nm alexandrite laser to treat facial photoaging in Asian skin: A prospective clinical trial.

AuNP-mediated PTT showed noticeable efficacy and tolerability in treating wrinkles and pores in Asian skin over a 12 week-follow-up. Further studies with a longer follow-up are needed to confirm the reduction in SG activity at the parameters used.
