Have you ever wondered about the actual science behind exfoliation? Perhaps you have wondered why the body doesn’t just exfoliate naturally. Actually, it does. But the mechanism behind how it works is actually what creates the need to exfoliate externally. It is all about a process known as desquamation.
You can go out and buy an excellent AHA serum from a company like Poéthique. That serum can do wonderful things for your skin. But even without the serum, your body is attempting to naturally exfoliate through desquamation. And in some people, the desquamation process works very well. In others, not so much. Thus, the need for AHA serums and other exfoliation products.
Desquamation in Plain English
Medical dictionaries and online resources define desquamation in terms that are often too technical for the rest of us to understand. So to make understanding this topic a little bit easier, this article will explain it in everyday English. To start with, desquamation is the body’s natural process for getting rid of dead skin cells and biological pollutants.
Human skin is constantly rejuvenating itself in order to replace dead skin cells with new ones. In fact, the body is constantly making new skin cells. The average healthy person has an entirely new epidermal layer of skin every 30 to 75 days. But how does it all happen?
New skin cells are generated in the lower layers of the skin. They are generated just as quickly as cells in the epidermis are dying. The body creates these new cells and then pushes them upward. Keeping them all together is a glue-like substance that the body produces for that very purpose. However, that sticky substance can create problems once a layer of dead skin cells reaches the surface. It can prevent those cells from naturally falling away.
It has been estimated that as many as 3 to 4 layers of skin cells in the outer portions of the epidermis consist mainly of those dead cells held together by the sticky substance. Until those layers are removed, the living skin cells underneath do not get proper nourishment. Thus, the need for exfoliation.
Removing Dead Skin Cells
A product like Poéthique’s AHA serum essentially helps nature do a better job. If you have pale, dull, tired-looking skin, it could be that you just need a little exfoliation. Your body is doing a wonderful job of pushing those dead skin cells to the surface. Now it just needs a little push to finish the job. That’s what exfoliation does.
A good AHA serum breaks the chemical bonds between dead skin cells so that they can be wiped or washed away. It also nourishes living skin cells underneath so that they start out on the right foot, so to speak. But even that is not all. It gets better.
Adding to the tired and dull complexion you are experiencing is all the pollutants your skin is exposed to. And in this day and age, those pollutants can be quite extensive. Exfoliation removes the pollutants along with dead skin cells and other debris. Furthermore, it goes deeper than mere soap and water. Exfoliation gets rid of all the nasty stuff and leaves fresh, healthy skin cells in its wake.
The science behind exfoliation is actually quite simple. When you move beyond all the complicated medical terms and long sentences that only serve to confuse, it turns out that exfoliation is just a way to help the body do what it naturally does – a little bit better. A good AHA serum can help do just that.
