Design outcomes

Primary

MeasureTime frame
Acne scar. Timepoint: The participants undergo 4 treatments with fractional non-ablative laser and Er;YAG 2940nm in two groups randomly (one fractional non-ablative group and one Er;YAG 2940nm group) at 4-week intervals. A basic clinical and photographic examination is done before each laser session and one month after the last laser session. Method of measurement: The method of measurement is based on the level of satisfaction of two dermatologists with the improvement of patients blindly according to GAIS (Global aesthetic improvement scale) criteria and photographic images. Also, the patient's assessment of recovery is measured according to the score given by the patient from 0 to 10.
