4 reasons to exfoliate your skin.

Keratinocytes are cells found in the epidermis. Over time, keratinocytes die through apoptosis (programmed cell death) and form dead cells that accumulate on the surface of the epidermis, which can give the skin a dull and tired appearance.

Theexfoliation process serves to remove these dead cells and impurities present on the epidermis. This can be achieved through a mechanical exfoliation which requires treatments based on granules, commonly known as scrubs. Thus, dead cells are removed through a mechanical action. As for thechemical exfoliation, it relies on active ingredients that break the bonds between the dead cells and the skin. These active ingredients particularly target glycoproteins, which facilitates the detachment of dead cells.

Blackheads , also known as "open comedones", are slightly raised clusters of fat that form on the skin due to clogged pores. The appearance of these unsightly obstructions is caused by an excess of sebum, as well as the accumulation of dead cells and impurities in the skin's enlarged pores. They get their name from their dark appearance on the surface. This coloration is the result of the oxidation of the content when it comes into contact with air.

By regularly eliminating dead cells and keeping the pores clear, exfoliation helps to maintain clean skin and prevents the buildup of sebum and impurities. Thus, exfoliation is an essential step that prevents the formation of blackheads and also helps to remove them by unclogging the pores.
