Objectives: The objective of this study is to assess the safety and efficacy of a novel 675 nm laser in the treatment of hypertrophic scars and keloids, focusing on significant scar improvement and reduced recurrence rates over a one-year period. Introduction: Keloids and hypertrophic scars, which are the result of abnormal wound healing, present substantial therapeutic challenges as a result of their potential for recurrence and aesthetic challenges. Promising results have been achieved through recent developments in laser therapy, particularly the 675 nm wavelength laser. This study examines the efficacy, patient satisfaction, and recurrence rates of keloid and hypertrophic scar treatment using this innovative laser over a one-year period. Materials / method: The 675 nm laser was used to treat a cohort of 30 patients who had hypertrophic scars and keloids. The treatment protocol consisted of multiple sessions that were separated by four weeks, with the number of sessions being determined by the severity and response of the scars. Patient-reported outcomes for discomfort and satisfaction were recorded using a visual analogue scale (VAS), and scar assessments were conducted using the Vancouver Scar Scale (VSS). Subsequent assessments were implemented at three, six, and twelve months subsequent to treatment. Results: The results showed a substantial improvement in the texture and appearance of both hypertrophic scars and keloids. The scars' pigmentation, pliability, and height were reduced by an average of 73%, as indicated by the VSS scores. The average VAS score was 8.5 out of 10, indicating high patient satisfaction. The average VAS score was 2 out of 10, and the pain experienced during treatment was minimal. Only 10% of patients experienced any increase in the scar volume within the one-year follow-up period, indicating a notably low recurrence rate. Conclusion: The 675 nm laser exhibits significant efficacy in the treatment of hypertrophic scars and keloids, providing significant improvements in scar appearance and texture, as well as high patient satisfaction and minimal discomfort. The laser modality's potential for long-term scar management is indicated by the low recurrence rates that were observed over the one-year period. There is a need for additional research that includes extended follow-up periods and larger sample sizes to verify these findings.
