Subjects were randomised to one of two dose groups, each with four concentrations of intradermal Prevascar. Subjects had four 1cm incisional wounds made on the inner aspect of each upper arm (eight in total), giving four sets of anatomically paired wound sites per subject. Each subject acted as their own control with one site from each wound pair randomly treated with intradermal Prevascar and the other treated with Placebo (vehicle) or Standard Care.
