Trial Outcomes & Findings for Botulinum Toxin is a Potential Prophylactic Therapy for Minimizing Post-excisional Scarring (Allergan Botox Scar Study) (NCT NCT02623829)

NCT ID: NCT02623829

Last Updated: 2020-12-08

Results Overview

MMSS scores range 5-18, higher score indicates poorer health outcomes. The MMSS assesses color, texture, distortion and contour of the scar.
