Can the epidermis be repaired?
Epidermal healing, or reepithelialization, is the renewal of the epidermis that has been damaged by a wound or a burn. Epidermal healing is a chief concern for wound repair since all wounds are intended to ultimately be covered with an epithelium.

The epidermis constantly renews itself: New cells are made in the lower layers of the epidermis. These move to the surface within four weeks. This constant renewal serves to replace the cells that are lost and fall to the ground as tiny flakes of skin when the skin is rubbed.
How does the epidermis heal?
Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.

Your skin is made up of the epidermis (the outer protective layer of skin) and the dermis (the layer of skin below the epidermis that contains blood vessels and nerves).

When dermal tissue is pierced, your immune system springs into action. Macrophages (white blood cells) disinfect the wound, remove debris and increase blood flow to the wound area.
What happens to the collagen in a wound?
During the final stage, newly formed collagen is rearranged and converted from type III to type I. This type of collagen adds strength to the wound, and the process causes the dermis to contract by 40 to 80 percent, pulling the wound edges together and closing the wound.
