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

This study demonstrated the potential of a new 730 nm picosecond-domain laser for the clearance of lentigines. The results showed good clearance with no adverse events and good subject satisfaction in patients with skin type II-III. Additional studies need to be conducted on darker skin types. The histopathologic findings demonstrate that the picosecond 730 nm laser produces excellent selectivity for pigment with minimal disruption of the dermal-epidermal junction and may therefore reduce healing times and the risk of adverse events.
