Citric acid, an alpha-hydroxy acid (AHA), is a versatile ingredient commonly used in skincare products, from face cleansers to shampoos. Citric acid is extracted from citrus fruits like lemons, limes, oranges, and grapefruits. It’s widely used in skincare, food, and household products as a preservative and exfoliating agent.

• Exfoliation: Like other AHAs, citric acid promotes cell turnover by dissolving the bonds between dead skin cells. This unclogs pores, evens skin tone, and improves texture.

• Antioxidant Properties: Citric acid is a good source of antioxidants, combating free radicals & protecting the skin from oxidative stress.

• Inhibits Melanin Production: It helps reduce hyperpigmentation by inhibiting excess melanin production.

• Buffering Agent: Citric Acid helps keep the pH level of the product consistent, which is crucial for skin health. Our skin has a naturally slightly acidic pH, which helps to keep the skin’s barrier function intact. If a cosmetic product has a pH level that’s too high (alkaline) or too low (acidic), it can disrupt this balance, leading to potential skin issues like irritation or dryness. By helping regulate the product’s pH to a level that’s more in sync with our skin’s natural pH, Citric Acid ensures that the product remains skin-friendly while retaining its effectiveness.

• Chelating agent: Citric Acid’s role as a chelating agent cannot be understated. In this capacity, it binds with metal ions that can sometimes be present in a product or in the water used with the product. These metal ions, if not neutralised, can speed up product deterioration, promote bacterial growth, or even cause colour changes. Citric Acid, by effectively binding with these ions, neutralises their impact, thereby enhancing the product’s overall stability and shelf life.
