yes. all skin cells divide and divide and divide all over your body.
In humans, rapidly dividing cells, such as skin and gut divide as often as once per day. Other cells such as brain and nerve tissue divide rarely in an adult.
matrix cells
Unlike most cells in an adult body, an embryonic mass of cells is always dividing. Most cells in the adult body is quiscent and will not divide unless signals have been given to them to divide, and many cells such as muscle and nerve cells have even lost the ability to divide.
Nerve cells will most likely NOT continue to divide.
Labile cells (the kinds of cells that can divide throughout their lifetime) normally do so within the organ they constitute. Some examples of labile cells are skin cells, cells of the gastrointestinal tract, and blood cells; however, blood cells divide in the bone marrow and lymphocytes divide in the lymph nodes. Other kinds of cells in the body are either stable cells (that do not normally divide--this includes nerve cells) and permanent cells (that do not have the ability to divide.)
All cells die at some point. If cells, including skin cells didn't divide, there would be no living skin cells. And that's not good.

Skin cells are damaged faster than your liver cells so the divide more often
In humans, rapidly dividing cells, such as skin and gut divide as often as once per day. Other cells such as brain and nerve tissue divide rarely in an adult.
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
The Bascal Cell Layer, the deepest layer where cells divide to produce new skin cells.
matrix cells
because the skin is constantly needing repair
Germ cells use a similar, but not identical, process to divide known as meiosis. Many adult cells do not divide at all under normal conditions, such as neurons and red blood cells.
Unlike most cells in an adult body, an embryonic mass of cells is always dividing. Most cells in the adult body is quiscent and will not divide unless signals have been given to them to divide, and many cells such as muscle and nerve cells have even lost the ability to divide.
Nerve cells will most likely NOT continue to divide.
Skin cells divide via mitosis - therefore the new cells will have the same number of chromosomes as the original cell. Therefore in humans, the new skin cells will have 46 chromosomes.
