Name of outermost layer of the skin?
It depends on which structures you are calling skin. The skin is made of dermis and epidermis. The outer thin layer is the epidermis, but it itself, is made of 4-5 layers depending on where it is located on the body. The most outer and the thinnest of the epidermal layers is called the coreum. It is the layer that we shed as it dies off and falls off.

How is damaged skin repaired?
Actually it is not that difficult for the skin to repair itself when only the epidermis is damaged. It's when the dermis is injured that the process becomes more complicated. It is difficult to only injure the epidermis, but it happens. The epidermis is avascular, meaning it does not contain blood vessels and therefore does not bleed. Epidermal wounds usually involve only minor damage to the superficial epidermal cells although the center of the wound could extend slightly into the dermis. These types of wounds include minor skin abrasions, where a portion of the skin has been scraped away, and minor burns. In response to an epidermal injury, basal cells from the deepest layer of the epidermis --the stratum basale-- surrounding the wound break off from the basement membrane (epidermal-dermal junction). The cells then enlarge and migrate across the wound. The cells continue to migrate until they meet cells migrating from the opposite side of the wound. Migration of the cells stops when each cell is finally in contact with other epidermal cells on all sides. As the basal epidermal cells migrate, a hormone called epidermal growth factor stimulates basal cells to divide and replace those who have left to fill in the wound. The relocated basal epidermis cells divide to build new strata, thus thickening the new epidermis. Viola, the skin is repaired!

Are the outermost cells of the epidermis living or dead?
Cells in the lower layers of the epidermis divide continually, producing new cells that constantly push through the layers of the epidermis. By the time those cells reach the outer layer of the epidermis, they are dead and ready to slough off.
The portion of the epidermis from which cells are constantly sloughed off is the?
