Brief Summary:
This is a randomized, controlled, within-patient, single-blinded, pilot study that will evaluate the impact of laser treatment on burn HSc relative to self-matched control scars. The studied primary outcomes of treatment are scar pliability, thickness, vascularity, pain, itch and patient satisfaction.

Condition or disease Intervention/treatment Phase
Burns Procedure: Laser treatment Not Applicable

Detailed Description:
Prior to treatment initiation, two independent scars sites will be selected and an anatomically- on each individual. At the selected treatment site the scar will be treated with the CORE fractional CO2 laser Participants will receive 3 treatment sessions scheduled 4 weeks apart. The scar sites will be evaluated at baseline, immediately before the 3rd treatment and 12 weeks after their final treatment session.
