Citric Acid

One of the most common uses of citric acid in cosmetics is as a pH adjuster. Citric acid can be used to lower the pH of a formulation, which is important for maintaining the skin’s natural pH balance. When the pH of a product is too high or too low, it can cause irritation and other skin problems. By using citric acid as a pH adjuster, cosmetic manufacturers can ensure that their products are safe and effective for use on the skin.

Another important use of citric acid in cosmetics is as an exfoliating agent. Citric acid is a natural alpha-hydroxy acid, which means that it can help to loosen and remove dead skin cells from the surface of the skin. By removing these dead cells, citric acid can help to reveal smoother, brighter, and more youthful-looking skin. Citric acid can also help to reduce the appearance of fine lines and wrinkles, making it a popular ingredient in anti-aging products.

Citric acid is also a powerful antioxidant, which means that it can help to protect the skin from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to the aging process. By neutralizing these free radicals, citric acid can help to protect the skin from premature aging and other forms of damage.
