Replaced
No the outer layer of the skin is not made of living cells. it is made of dead cells.
Humans shed and regrow outer skin cells about every 27 days.
The skin consists of two layers, the inner and thicker dermis, and the outer and thinner epidermis. It takes about 35 days for the epidermis to replace itself. It replaces itself quicker than other parts of the body because it is exposed to the outside world and is constantly being abraded, cut, or scratched.
for children about 50 days but for adults about 100 days
the stem cells of the stratum basale are in constant state of mitosis, replacing cells that have rubbed off the epidermal surface. as they are produced by stem cells, new keratinocytes push previously formed cells toward the surface.
Replaced, I believe.

You grow an entirely new set of skin cells every seven years.
The epedermis, the outer and the thinnest layer of your skin! :)

Skin cells have intercellular matrix which controls communication in the skin. This is as a result of the loose outer later of the skin which gives it an identity.
Partially. The dermis and lower part of the epidermis are alive, but the outer layers of the epidermis consist of dead cells.
So you can show off your new skin

Bacteria is constantly forming on the outer layer of your skin. It is looking for a way to invade your body. Your body reacts by simply throwing away the outer layer of your skin. It does that a cell at a time, but it does it constantly. Those cells must be replaced. To do that, the cells underneath must constantly reproduce and create new skin cells.
Epithelial cells are the outer cells of the skin.
That is called tissue.
