Brief summary

Subjects will have a bruise induced. A pad containing either a placebo or active will be applied to the bruise. Photographs will be taken over the following days to record bruise healing.

Detailed description

This is a randomized, double-blind, placebo-controlled, crossover, multicenter study that will be used to evaluate the difference in bruise reduction efficacy between active remedy and placebo when a mechanical bruise is induced. The trial will be conducted at 5-8 sites with up to 150 subjects. Each subject will be injured two times using the same bruise-inducing mechanism, and the resulting bruises will be treated with active remedy or placebo-infused pads that will be identical in appearance. Subjects and study investigators will be blinded to the order of treatment assignment. Subjects will be asked to come to the clinic for photographic assessments of the bruise. Each subject will be randomly assigned to have a placebo or active remedy pad applied over each mechanically induced bruise on Day 1. The pad will be applied by study staff immediately after bruise induction (within 5 minutes). The pad will cover the bruised area completely, and then sealed with Tegaderm. All procedures, including bruise induction, treatment, and photography, will be administered by study staff who are blinded to treatment type. All photographs will be rated according to standardized criteria by blinded, trained study investigators after the completion of all subject data collection.
