Skin Fractional Scar Treatment with a New Carbon Dioxide Scanner: Histological and Clinical Evaluation.

Abstract

Background: The mechanism of action of fractional carbon dioxide (CO2) laser in the management of skin scarring is stimulation of collagen and fibroblasts in the dermis, resulting in remodeling and shrinking of the skin. Objective: The purpose of this research is to assess the safety and performance of a new CO2 laser scanner for treatment of acne scars. Methods: The study was carried out on 20 patients of both sexes, with a mean age of 25.7 ± 6.7 years. To assess the performance and safety of this new CO2 scanner, a preclinical histological evaluation was done. A clinical evaluation of acne scars was performed using Goodman and Baron's quantitative global acne scarring grading system (GBQGASGS) and a crusting scale where crusting scores ranged from 1 = none to 4 = severe. Digital photographs were taken to obtain esthetic results. Results: GBQGASGS showed a significant improvement in patients' scars and the treatment was well tolerated, with no lasting side effects. Conclusions: The new scanner seems to be an effective and safe device for skin scarring treatment, speeding up the healing time of scars.
