Exfoliation simply means the removal of corneocytes on the skin’s epidermis. This complicated immune organ sheds billions of skin cells daily; however, when this natural desquamation slows down or stops due to ultraviolet ray damage, dehydrated or oily skin, winter cold injury, genetics, or skin disorders, the end point is clearly identifiable ensuing in flaky skin, congested pores, and various inflammatory/non-inflammatory acne lesions, resulting in uneven, blotchy, and aged skin.
Exfoliants have been around for centuries and used to rid the epidermis surface of epithelial cell buildup to bring balance back to the skin. This integral exfoliation step in both professional treatments and homecare causes the skin to rid pore toxins, control acne breakouts, remove transient pigmentation, smooth wrinkles, and eliminate the thick, dry corneocyte barrier for better penetration of topicals to replace important indigenous nutrients for a prolific new generation of cell turnover, assembling a younger-acting epidermis. Today, there are many different skin exfoliants for face and body. They range from mechanical to chemical constituents.
Mechanical exfoliation techniques vary from mesh sponges, gauze, brushes, pumice stones, microfibers, exfoliation sheets, microbead facial scrubs, apricot or almond shells, sugar, salt crystals, corundum, pumice, loofahs, microdermabrasion, or mechanical brushes, just to name a few.
To identify some of the professional chemical exfoliant topicals available, there are salicylic, glycolic, lactic, citric, malic, pyruvic, and trichloroacetic acids, Jessner, enzymes, protease, and fruit enzymes.
