A novel 1565 nm non-ablative fractional device for stretch marks: A preliminary report

Abstract

Background: Striae Distensae (SD) is a very common dermatologic condition. We evaluated the effectiveness and safety of a novel non-ablative fractional 1565 nm laser (ResurFX) on the appearance of SD. Materials and methods: Twelve Caucasian subjects with various stages of SD received three non-ablative laser treatments. Each treatment consisted of two different laser settings, in order to achieve a demarcated dense impact together with a diffused deep impact. Three months after the last treatment, SD improvement was assessed by blinded and non-blinded reviewers using clinical images and 3D image analyses. Results: Good clinical improvement (between 51% and 75%) was observed in all patients. Most patients showed improvement of > 50% in the volume of depressions and in lesion color (91.7% and 83.3% of patients, respectively). The average pain during treatment was generally defined as tolerable and the average downtime was 4 days. Transient erythema and severe edema were noted immediately after the procedure, but long-lasting or severe adverse effects were not observed. All patients noted a good improvement and were satisfied with the treatment and the results. Conclusions: The treatment with the 1565 nm ResurFX laser resulted in improved pigmentation, volume, and textural appearance of SD.
