Exfoliation is a natural process in which skin cells are created, removed, and replaced. The peeling process takes place in the outermost layer of the skin called the epidermis . The epidermis itself is made up of four unique layers. Each of these layers plays a role in flaking.
Skin cells are born
Sometimes called cell turnover , the peeling happens every second of the day and you don't even notice it.
New skin cells are created in the germ layer, which is the deepest layer of the epidermis. This layer is also called the basal layer.
Skin cells begin life as a single layer of thick columnar cells. These cells are responsible for the creation of all the cells in your skin.
The cells in this layer are dividing. Half of them remain in the germ layer. The rest of the cells begin to migrate to the surface of the skin.
Your next stop is the thorny cape. Here, the skin cells change the shape of your spine to a shape that looks more like a polygon.
The spiny layer is also called the "spiny layer" because these polygonal cells look quite spiny when you look at them under a microscope.
It is here, in the spiny layer, where skin cells begin to produce keratin, the tough fibrous proteins that make up the basic structure of the skin. ( Keratin is also an important component of your hair and nails.)
Cells line up
Skin cells continue to move upward from the spiny layer to the granular layer. In this layer, cells begin to line up. They also lost their core.
This layer is also called a "grainy layer". Do you want to guess why? Yes, because here the cells take on a grainy appearance.
Cells reach the surface and then shed
Skin cells have reached their final destination: the stratum corneum. Once the cells reach this top layer of the skin, they are essentially dead.
The cells of the stratum corneum are very flat and densely packed. These flat dead cells continually fall off as new cells come to the surface. Thus, your skin is constantly renewed.
Where do all those dead skin cells go? You might be surprised to learn that most of the dust in your home is actually made up of dead skin cells.
The entire desquamation process, from cell birth to desquamation, takes 14 to 28 days.
Role of abnormal flaking in acne
The peeling process is believed to go awry in people with acne . Dead skin cells linger longer than they should, clogging pores and contributing to breakouts. That is why exfoliating treatments can help improve the condition of your skin.
