About

The purpose of this study is to explore the effects of pulsed dye laser on managing scar vascularity and thickness.

Full description

The pulsed dye laser is increasingly used in clinical settings to manage scars and shows promising outcomes.The pulsed dye laser targets at micro-vascular structures in scar tissues. This study aims to explore the vascularity changes in scars with pulsed dye laser during the scar formation process.
