Treatment of facial and non‐facial lentigines with a 730 nm picosecond titanium: Sapphire laser is safe and effective

Objective A 730 nm picosecond‐domain laser was developed to improve the clearance of pigmented lesion and reduce adverse events. This study assessed the safety and efficacy of this system for the clearance of lentigines and explores how the short picosecond pulses interact with tissue via histology. Study Design and Methods Twenty subjects with Fitzpatrick skin types II–IV were enrolled in this prospective, IRB‐approved study. Four treatments...
