An illustrative image demonstrating a proposed skin wound-healing process with the application of nano collagen powder. The image demonstrates how the powder is applied and fills in the skin wound, where its nano-sized particles better attach to all the crevices of the wound. The nano collagen powder then absorbs exudate secretion and blood, creating a wet microenvironment which acts as a temporary bio-template in the wound. This allows the damaged cells to absorb and benefit from the collagen applied, enhancing healing by encouraging cell migration and proliferation.
