Furthermore, the 940nm wavelength corresponds with a lesser absorption peak of oxyhemoglobin than that for 532 nm, leading to slower and even more uniform heating system of the vessel,’ stated lead writer Emily Tierney, MD, an associate professor of dermatology at BUSM. ‘Furthermore, there is minimal melanin absorption at the 940nm wavelength, and thus, there is less risk of post-inflammatory scarring or change,’ she added. Provided the efficacy and safety of the 940nm wavelength laser, the researchers recommend this wavelength be added to the typical treatment facial vasculature.. 940nm wavelength laser is first-class for treating face spider veins: BUSM researchers Researchers from Boston University College of Medicine have concluded that the 940nm wavelength laser is better for treating facial spider veins when compared with the 532nm wavelength laser.Taylor, D.O., Robert H.
