What is a skin graft?

A skin graft is a surgical procedure that involves the transplantation of healthy tissue to an injured site. This procedure is often utilized to promote wound healing, replace lost skin due to injury or disease, or repair areas where the skin has been damaged, such as in burns or surgical wounds. The graft can be taken from the individual’s own body (autograft) or may come from a donor (allograft). The primary purpose of a skin graft is to restore skin integrity and facilitate the healing process, making this choice the most accurate definition.

The other options describe different medical concepts that do not align with the definition of a skin graft. For instance, a chemical treatment for acne pertains to dermatological treatments rather than surgical procedures. An epidermal growth may refer to skin formation or regeneration but does not specifically denote the procedure of transplanting tissue. A type of skin infection involves pathogens affecting the skin, which is unrelated to the process of grafting healthy tissue to aid in healing.
