Exfoliation (cosmetology)


Exfoliation involves the removal of the oldest dead skin cells on the skin's outermost surface. Exfoliation is involved in the process of all facials, during microdermabrasion or chemical peels at medical spas. Exfoliation can be achieved through mechanical or chemical means.

Credit is given to the ancient Egyptians for the practice of exfoliation. In the Middle Ages, wine was used as a chemical exfoliant, with tartaric acid as the active agent. In Asia, the practice of exfoliation started hundreds of years ago. The etymology of the word exfoliate comes from the Latin exfoliare (to strip off leaves).

Exfoliation is achieved through either mechanical or chemical means.

This process involves physically scrubbing the skin with an abrasive. Mechanical exfoliants include microfiber cloths, adhesive exfoliation sheets, micro-bead facial scrubs, crepe paper, crushed apricot kernel or almond shells, sugar or salt crystals, pumice, and abrasive materials such as sponges, loofahs, brushes, and simply fingernails. Facial scrubs are available in over-the-counter products for application by the user. People with dry skin should avoid exfoliants which include a significant portion of pumice, or crushed volcanic rock. Pumice is considered a good material to exfoliate the skin of the feet. Microdermabrasion is another mechanical method of exfoliation.
