There’s a good reason for the phrase, “baby-smooth skin.” When you’re young, your skin naturally renews itself every 28 days, bringing new, healthy cells to the surface. But as you age, the skin renewal process slows down to more than 40 days. This causes dead cells to pile up, leaving you with dull, rough, and blemished skin. This is where exfoliating acids like glycolic and phytic acid can help.
Glycolic acid is a natural exfoliating ingredient that is derived from sugar cane. This chemical exfoliant is a part of the alpha hydroxy acid (AHA) family. Because of its low molecular weight, it is the most popular AHA used in exfoliating products. Glycolic acid’s small molecules allow it to go deeper into your skin. This helps it slough away dead surface cells and stimulate more collagen production in the dermis.
Another exfoliating acid, phytic acid is a gentler AHA that also has potent antioxidant properties. This mild acid is typically derived from plant-based sources, such as grains and legumes. In addition to reducing pigmentation and brightening skin, phytic acid also neutralizes harmful free radicals that damage skin cells. By accelerating cell renewal and protecting against further damage, phytic acid can slow down the appearance of skin aging.
