Non‐Ablative Fractional 1940-nm Diode Laser for Skin Resurfacing and Treatment of Benign Pigmented Lesions
Author: Waibel JS, Schallen KP.
A prospective study evaluated treatment with the 1940 nm fractional diode laser (Nordlys® device) for improvement of skin pigmentation and texture. Fifty‐four participants (4 males, 50 females; mean age of 53.8 years; Fitzpatrick Skin Types I-IV) with mild to severe benign pigmented lesions on the face or body received up to three laser treatments. Blinded evaluation of randomized pretreatment versus 1‐month posttreatment photos was conducted by three independent dermatologists to identify the correct posttreatment image and assess pigmentation on a 5‐point scale (0 = 0% improvement, 4 = 75%–100% improvement) and skin texture improvement.
Blinded evaluation resulted in a 91% success rate of correct identification of posttreatment photos with a mean pigmentation improvement score of 2.0 (p < 0.05) and improvement in skin texture for 62% of treated areas. Subjects were highly satisfied with the treatment outcome, which was considered safe and tolerable.
