Citric acid is an alpha-hydroxy acid derived from citrus fruits, used primarily to adjust and buffer formulation pH and as a chelating agent, and at higher concentrations as a mild chemical exfoliant. It can promote surface cell turnover and is sometimes included in antioxidant or brightening products.
Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types.
