If the skin is unable to protect against wounds, it has the ability to renew its cells and even to heal. In the case of a minor wound, only a part of the epidermis is damaged. The cells that have been destroyed are replaced by new ones which are created from the innermost layer of the epidermis.
How does skin repair itself when the epidermis is damaged?
Fibroblasts (cells that make up most of the dermis) move to the wound area. Fibroblasts produce collagen and elastin in the wound site, forming connective skin tissue to replace the damaged tissue. Healthy granulation tissue is uneven in texture. It does not bleed easily and is pink or red in color.
What happens if the epidermis is removed?
As the epidermis is itself not vascularised—it is receiving blood from the dermis—a clotting and vasoconstrictive response is often not necessary. Immune cells may still be recruited to the wound site because the removal of the epidermal barrier makes the wound susceptible to infection.
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.
What helps skin grow back?

How can skin regenerate after damage?
The ability of the skin to heal even after considerable damage has occurred is due to the presence of stem cells in the dermis and cells in the stratum basale of the epidermis, all of which can generate new tissue.
