Nexagon™ is a novel compound that promotes wound healing by temporarily disrupting cellular communication at the wound site, thereby promoting accelerated healing, reducing inflammation and pain. This randomized double-blind study will assess the safety, tolerability and clinical effect of Nexagon™ when applied to skin wounds created by punch biopsy in healthy volunteers. 43 healthy, fair-skinned males and females between ages 18-40 will be enrolled. Subjects will be reviewed again at 3 months and 9 months for follow-up safety assessments and wound appearance evaluation.
