Participant Flow
Participants undergoing standard of care deroofing surgery in a medical clinic office will be randomized to dressing assignment per axilla: one axilla will receive the bioelectric dressing (e.g., left armpit) and the contralateral axilla (right axilla) will receive the standard gauze dressing for up to 8 weeks. Side assignment (right vs. left) will be determined by randomization.

SECONDARY outcome
Timeframe: Up to 8 weeksThe Modified Vancouver Scar Scale (MVSS) is a validated clinical tool used to assess scar quality. It includes four subscales: Vascularity (0-3), Pigmentation (0-2), Pliability (0-5), Height/Thickness (0-3). Each subscale is scored independently, and the scores are summed to produce a total score ranging from 0 to 13. Higher scores indicate worse scar quality (greater abnormality). Lower scores indicate better scar quality (closer to normal skin).
