3. Glycolic acid
This natural ingredient is gotten from sugar cane and can also be produced synthetically. It is categorized with a set of molecules called AHAs. These natural-based acids include glycolic, citric, lactic, and tartaric acids. AHAs exfoliate the skin and reduce fine lines, acne scars and age spots, as well as uneven skin color.
The ingredient is a natural exfoliator as it removes the topmost layer of dead skin on the skin and replaces it with fresher looking skin. It is used in different skin care products such as peels, lotions, creams, and cleansers.
