Glycolic Acid
Glycolic Acid is one of the most popular ingredients in skincare products. It belongs to a family of ingredients called alpha-hydroxy acids (AHAs) and is derived from sugar cane. Beauty professionals and skincare formulators use it because it helps remove dead skin cells, makes skin look fresher, and helps other skincare products work better. Think of it as a gentle exfoliator that helps reveal newer, healthier skin. Similar ingredients include lactic acid and mandelic acid. When you see this on a resume, it usually means the person has experience with product formulation, skin treatments, or working with exfoliating products.
