Citric Acid (AHA) is a member of the alpha hydroxy family of molecules that are derived from the use of the acids in lemons, limes, oranges, and grapefruits.
What is Citric Acid?
Citric acid is an alpha hydroxy acid used in skincare products to adjust the acidity or promote skin peeling and skin renewal in the case of anti-aging products. This class of acids is widely used in skin care products that are meant to exfoliate the complexion. Citric acid is a product for treating several skin problems like mild acne, pigmentation, clogged pores, sun tanning, wrinkles, and dark spots. Adding the ingredient to a formula makes it slightly more acidic and can help other ingredients in a particular product function more optimally.
Benefits of Citric Acid
Esters formed from citric acid create a thin protective layer on the skin that limits the amount of moisture evaporating from the skin. It thus optimizes the hydration of the skin. The esters of the acid help to smoothen the skin, providing additional hydrating benefits.
