Citric Acid is naturally found in citrus fruits. Lemons and limes have the highest content of citric acid which accounts for their sour tastes. Citric acid is also found in oranges, tangerines and some berries such as raspberries. Citrus acid has been found to readily bond to minerals and metals, making those ingredients more easily absorbed through the body. Calcium citrate for example is better absorbed than calcium alone. Citric acid can also be used as a natural preservative and to help balance the pH level of skin care products.
Citric acid contains a good amount of Vitamin C which is a known anti-aging ingredient. Vitamin C provides antioxidant protection while stimulating collagen production. Vitamin C has also been shown to help lighten discolorations or brown spots. Citric Acid is also an alpha-hydroxy acid which helps to exfoliate the skin and speed up the cell turnover rate.
Citric acid is derived from natural sources and poses very little risk to the environment. Citric acid is generally very well tolerated which makes it a popular ingredient for topical skin care products.
