Design outcomes

Primary

Measure	Time frame
To evaluate the efficacy of erbium and neodymium lasers in early scars. It is expected to find benefits in the appearance and functionality of the treated scars and, consequently, to improve quality of life. The outcomes will be verified through the following methods: clinical evaluation using validated scales (Vancouver and POSAS), Likert scale, photographic documentation, and dermatological ultrasonographic examination. All collected data will be subjected to statistical analysis. The significance level to be considered will be 0.05	—
