The body forms new collagen fibers (a naturally occurring protein in the body) to mend the damage, resulting in a scar. In the case of a minor wound, only a part of the epidermis is damaged. It appears as though the dermis itself will help with the regeneration of the epidermal cells. Damage to the dermis layer of skin is repaired through a process called granulation. Collagen is found within the dermis, the second layer of skin, and is responsible for a large portion of skin repair and keeping it young and healthy-looking. The permeability of the skin depends on the presence of chemical substances in the stratum corneum, the viable epidermis and the uppermost layer of the dermis.
