Experimental
No Intervention
Arm Label
Er:YAG laser Group
Control (No Intervention) Group
Arm Description
The study is a split-scar model. Participants will have half of their lesion receive a total of three sessions using 2940 nm Er:YAG laser spaced over a 4-week study participation interval.
The study is a split-scar model. Participants will serve as their own control and have half of their lesion receive no intervention.
