AbstractBackground: A current popular aesthetic problem, especially among younger women, is striae distensae (SD), also referred to as "stretch marks.". Aim: The potential use of the 675 nm laser has been investigated in the treatment of SD. Methods: Patients underwent three sessions of the 675 nm laser with a 1-month interval between sessions. A total of three sessions were performed. The Manchester Scar Scale was used to assess stretch mark changes, and the mean scores related to each parameter at baseline and 6M FU after the last treatment session were measured. A clinical photographic evaluation was performed to show the aesthetic improvement of SD. Results: The patients' treated areas were the abdomen, thighs, buttocks, and breasts. Mean scores related to each Manchester Scar Scale parameter, with their relative percentage change, at baseline and 6M FU after the last treatment session were significantly improved. The total mean Manchester Scar Scale score significantly diminished from 14.16 (±1.30) to 10.06 (±1.32) at 6M FU (p < 0.01). The clinical photographs showed promising aesthetic SD improvement. Conclusions: 675 nm laser therapy demonstrated a good tolerance for the treatment of stretch marks applied to various body areas preventing any discomfort for the patient and with a significant improvement in skin texture.
