CITRIC ACID

Description

Citric acid is a naturally occurring alpha-hydroxy acid (AHA) found in citrus fruits and widely used in skincare formulations. This versatile ingredient serves multiple purposes in dermatological products, primarily as a pH adjuster and mild exfoliant. Its ability to lower the pH of formulations helps stabilize other active ingredients and enhance product efficacy.

As an exfoliant, citric acid gently removes dead skin cells, promoting cell turnover and improving skin texture. This action can help reduce the appearance of fine lines, uneven skin tone, and mild hyperpigmentation. Additionally, citric acid possesses antioxidant properties, offering some protection against free radical damage.

In skincare, citric acid is typically used in concentrations ranging from 0.5% to 2%, depending on the product's intended purpose. It's often found in cleansers, toners, serums, and chemical peels. While generally well-tolerated, individuals with sensitive skin should introduce citric acid-containing products gradually to assess tolerance.

Beyond its exfoliating and antioxidant benefits, citric acid can enhance the skin's moisture retention capabilities and aid in the absorption of other active ingredients. Its multifunctional nature makes it a valuable component in various skincare formulations targeting diverse skin concerns.
