Studies have shown significant value in moist wound healing as opposed to treatment of wounds in a dry environment, and clinical evidence has supported this view for many years. Moist wound healing has been shown to promote re-epithelialization and can result in a reduction of scar formation because a moist environment keeps new skin cells alive and promotes cell regrowth.1
