The outermost
papillary layer
Sub-Cutaneous hair generating Follicles are embedded within the 15 layer thick Skin; the outermost seven Cell Layers are composed of dead Cells to form an essential protective Layer.
A layer of new cells is always better than a layer of old and dead cells. If your skin is dead then it wont be protecting you, instead it will spread the necrosis to your inside body parts and ultimately you'll either scar a lot or die. Nothing dead is every helpful to the body (hence why dead cells are always "recycled" and then flushed out of the body).
In the living dermis layer of the skin, by normal cell division like other cells. In the dead epidermis surface layer of the skin, they don't as the cells are already dead (they killed themselves before becoming part of the epidermis).
they are both composed of dead particles that come from the epidermis
The upper layer of skin i.e. Epidermis is composed of dead Keratinized epithelium cells.
papillary layer
The outer layer of our skin is composed of dead epithelial cells.
The outer most The statum corneum (horny layer) which is composed of 20-30 layers of dead cells
Sub-Cutaneous hair generating Follicles are embedded within the 15 layer thick Skin; the outermost seven Cell Layers are composed of dead Cells to form an essential protective Layer.
it i were to say, the dermis is composed largely of dead cells
it i were to say, the dermis is composed largely of dead cells
The epidermis is the top and most superficial skin layer in the body and is made of dead skins cells. You will shed these dead skin cells and they will fall., so you don't have a continuously growing layer of dead skin.

Epidermis
Phloem is actually composed of still-living cells that transport sap. Perhaps you are asking about xylem which is composed primarily of dead cells.
No the outer layer of the skin is not made of living cells. it is made of dead cells.
