A laser platform incorporating a novel 524 nm laser pumped by a commercial hair removal laser effectively treats facial redness and lower‐extremity spider veins

Background and Objectives Treatment of vascular lesions is one of the main applications of cutaneous laser technology, while the other is laser hair removal. We present here a vascular laser pumped by a commercial hair removal laser. Study Design/Materials and Methods A novel 524 nm vascular laser was designed using a 755 nm hair removal laser as a pumping source. This 524 nm vascular laser was used to treat facial redness and leg telangiectasias in 24 subjects. Four treatments were administered to the face at 4–6‐week intervals and final photographs were taken 8 weeks following the final treatment, while two treatments were administered to lower‐extremity spider veins at 2‐month intervals with follow‐up photographs 3 months following the final treatment. Blinded analysis of digital images was performed by two physicians not involved in the study. Results Blinded evaluation of digital photographs revealed an average improvement score of 3.3 ± 1.7 (mean ± SEM) on a 0–10 scale for removing facial redness (p
