Desquamation is a natural process that occurs in the skin, involving the shedding of dead skin cells from the surface of the skin. This shedding is a continuous process, where the older, dead skin cells are replaced by new ones.
Desquamation is the process of shedding dead skin cells on their own without using any specific products or ingredients. It is a normal part of the skin’s renewal process. Exfoliation and peeling, on the other hand, involve the intentional removal of skin cells by using products or other substances like acid or physical exfoliation.
The process of desquamation is regulated by enzymes called proteases, which break down the bonds between the dead skin cells or corneocytes and the surrounding tissue, allowing the cells to detach and slough off. This process helps to maintain the integrity of the skin, by removing the old and damaged skin cells and replacing them with new ones.
However, various factors can interfere with the natural process of desquamation, leading to skin issues such as dryness, flakiness, and a rough texture. Factors such as aging, environmental stressors, certain medications, and medical conditions can affect the rate of desquamation, causing an accumulation of dead skin cells on the surface of the skin.
