About this study
The goal of this clinical trial is to compare the efficacy and safety of long-pulsed ND:YAG laser and intense pulsed light in the treatment of traumatic and post-surgical erythematous scars. Forty patients presenting with traumatic and post-surgical erythematous scars on the head and neck, of six months' duration or less, were randomly divided into two equal groups. Group A patients received long-pulsed ND:YAG laser sessions, while Group B patients received intense pulsed light sessions. Four sessions were given at four-week intervals.
