Which component in skincare products is known for its exfoliating properties?

Glycolic acid is a type of alpha hydroxy acid (AHA) that is widely recognized for its exfoliating properties. It works by breaking down the bonds between dead skin cells on the surface of the skin, promoting their removal and revealing fresher, more radiant skin underneath. This effective exfoliation can help improve the appearance of fine lines, uneven skin tone, and rough texture, making glycolic acid a popular ingredient in various skincare products, particularly those aimed at anti-aging and skin rejuvenation.

In contrast, shea butter and cocoa butter are both emollients and occlusives, primarily used to hydrate and nourish the skin rather than to exfoliate. They help to restore moisture and create a protective barrier, making them ideal for dry skin but not specifically for exfoliation. Vitamin E is an antioxidant that helps protect the skin from free radical damage and also aids in moisturizing, but it does not have the exfoliating action associated with glycolic acid.
