A pilot trial using topical regular crystalline insulin vs. aqueous zinc solution for uncomplicated cutaneous wound healing: Impact on quality of life.

When wounds are treated with regular insulin, they are also being treated with zinc; used in the formula to crystallize insulin molecules. It is not clear if regular insulin-accelerated wound healing is due to insulin, the zinc it contains, or both. Thus, we aimed to compare topical regular crystalline insulin (containing zinc) vs.
