All patients were examined before the start of the study and two months after completion of the study as described below:Determination of the Vancouver scar scale for both groups, which assesses four characteristics of the lesion, including vascularity, pigmentation, height, and flexibility. According to the items listed in Fig. Skin burn scar before and after treatment with fractional COThe sum of all scores is examined to evaluate the improvement of the lesion (Table Vancouver scar scale [Biometric assessment in both groups before and 2 months after completion of treatment. For this purpose, the following quantitative parameters and a probe with a frequency of 75 Hz were used:Corneometer: to measure tissue hydration (stratum corneum layer).Mexameter: to measure the amount of melanin and erythema of the lesion.Tewameter: to measure transepidermal water loss.Colorimeter: to measure color changes of the skin.Cutometer: to determine the elasticity of the tissue and includes the following parameters:R2: viscoelasticity.R5: pure elasticity.R7: percentage of immediate recovery compared to amplitude after suction.Patient and physician satisfaction with treatment in both groups is based on the overall assessment of patients and physicians and includes the options of No Response, Little, Somewhat, Good, and Excellent, which are rated as 0, 1, 2, 3, and 4 points, respectively.
