As skin ages, the ability to slough dead, damaged and maturing cells slows making young, healthy cells less able to surface. Enzymes help break down the impacted layers of dead cells that cause skin to become dull, stiff and crease easily. Enzyme exfoliants are ideal for “digesting” dead cells. They provide gentle exfoliation that targets dead skin cells that slow down healthy cell renewal – the leading cause of the appearance of dull, sluggish skin.
