The human skin produces about one million skin cells every 40 minutes! As skin cells are produced from the deepest layer and move towards the surface, older cells harden, lose moisture, and detach from skin. This process is called desquamation, and it helps eliminates damaged, contaminated cells that carry environmental pollutants.
As we age, desquamation slows, and can cause skin dullness, follicle clogging, and dryness. Through exfoliation, dulling skin cells are effectively removed and newer cells are revealed for a fresher, healthier appearance.
Physical exfoliants including Corn Cob Meal or Rice Bran remove dead skin cells through friction. (Steer clear of exfoliants made of nut shells or ground-up fruit pits, as these will scratch skin, which is dramatically different from exfoliating skin). Chemical exfoliants work by dissolving the intercellular "glue" that attaches skin cells, allowing separation and removal from skin. Chemical exfoliants include Lactic Acid and Salicylic Acid.
