ABSTRACT
BACKGROUND AND OBJECTIVES:
The efficacy of picosecond laser (PSL) in the treatment of striae distensae (SD) has been recently reported; otherwise, the base for this improvement has not been clarified yet. The aim of this study is to treat long-lasting SD with PLS and to describe their in vivo morphological variations after treatment using three-dimensional (3D) imaging and reflectance confocal microscopy (RCM). STUDY DESIGN/MATERIALS ANDMETHODS:
A total of 27 patients asking for treatment for SD were treated with four monthly sessions of PLS. Clinical improvement was estimated through a blinded evaluation performed by two independent dermatologists, Global Assessment Improvement Scale (GAIS), patients' satisfaction, 3D imaging, and RCM assessments at baseline and 6 months after the last laser session.RESULTS:
Although a clinical improvement of SD was observed in 81.4% of patients according to physicians' GAIS, only 66.6% of patients reported subjective improvement and satisfaction after treatment (P = 0.04). 3D imaging revealed a significant improvement in terms of skin texture (P < 0.001) and mean SD depth (P < 0.001). Otherwise, RCM highlighted collagen remodeling and the appearance of new dermal papillae in all the treated SD compared with baseline.CONCLUSIONS:
The present study confirms that PLS represents a safe treatment option for SD; herein, we report morphological documentation of skin variations after PLS treatment. Lasers Surg. Med. © 2021 Wiley Periodicals LLC.Palavras-chave
