**Core Concept**
A full thickness graft, also known as a split-thickness skin graft (STSG), is a type of skin graft that includes both the epidermis and the entire thickness of the dermis. This graft is typically harvested from a donor site on the patient's body.

**Why the Correct Answer is Right**
Full thickness grafts are not typically harvested from the skin of the face, as the skin in this area is relatively thin and would leave significant scarring. The skin on the face has a unique anatomy, with a thinner dermal layer and a higher concentration of sebaceous glands, making it less suitable for full thickness grafting. In contrast, areas such as the thigh, buttocks, or back are more commonly used as donor sites for full thickness grafts.

**Clinical Pearl / High-Yield Fact**
When considering donor sites for full thickness grafts, it's essential to choose areas with a sufficient thickness of dermis to minimize the risk of graft failure and scarring. The thighs, buttocks, and back are often preferred due to their relatively thick dermal layers.
