Summary Background Multiwavelength lasers are reportedly useful for treating venous lake ( VL ) in Caucasian patients. However, the same parameters may not be safe for Asian patients with Fitzpatrick skin type ( FST ) IV . Purpose Report experience with using multiwavelength laser for VL treatment in Asian patients with FST IV . Methods Seventeen episodes of VL in 15 Chinese patients with FST IV were treated. 595‐nm pulsed dye laser ( PDL ) followed by 1064‐nm neodymium‐doped yttrium aluminum garnet (Nd:YAG) laser was administered. The treatment was performed with 7‐mm spot size at 7‐11.5 J/cm 2 , 2‐10 ms with PDL , followed with Nd: YAG at 35‐40 J/cm 2 , 15‐40 ms. The laser treatment was performed with a single pass without overlap. Results Complete resolution was observed in 14 lesions after 1‐2 treatment sessions, with 10 ms duration of PDL . The remaining three patients achieved 80%‐90% resolution after 1‐3 treatment sessions, with 2 ms duration of PDL . Only one case exhibited recurrence after 1 year. Conclusion Multiwavelength laser treatment for VL is highly effective and safe in Asians, although a much lower fluence of Nd: YAG is used, as compared to that used in Caucasians in the literature. Moreover, an appropriate PDL pulse duration (10 ms) ensures better outcomes.
