1. Definition Citric Acid:

Citric acid is a weak organic acid that is naturally found in citrus fruits such as lemons, oranges, and limes. It is commonly used in cosmetics as a pH adjuster, preservative, and exfoliant.

2. Use:

Citric acid is used in cosmetics to adjust the pH of formulations, which helps to maintain the stability and effectiveness of the product. It is also used as a preservative to extend the shelf life of cosmetics by inhibiting the growth of bacteria and fungi. Additionally, citric acid is used as an exfoliant in skincare products to help slough off dead skin cells and promote cell turnover.

3. Usage Citric Acid:

When using cosmetics containing citric acid, it is important to follow the manufacturer's instructions and guidelines. Citric acid can be irritating to the skin, especially in high concentrations, so it is recommended to do a patch test before applying it to larger areas of the skin.
