The skin is the largest organ of the body, which meets the environment most directly. Thus, skin regeneration is particularly important in meeting the skin’s need to be resilient against environmental damages. Skin healing is a serious process involving several types of cells, as well as cytokines, mediators, the neurovascular system, and matrix remodeling. Tissue regeneration technology remarkably enhances skin repair by re-epidermalizing cells, regenerating cells from other parts of the body, creating new blood vessels that help to heal wounds, and improving the way that scars and keloids heal. Various skin substitutes have contributed to the increasing success rates of skin healing.
