Acids

Acids play a multifaceted role in cosmetics, contributing to both the formulation and effectiveness of various skincare and beauty products. One widely used acid in the cosmetic industry is citric acid, which is a natural alpha hydroxy acid (AHA) derived from citrus fruits. In skincare, citric acid serves as an exfoliant, helping to slough off dead skin cells and promote cell turnover. This action can result in smoother, brighter skin and is particularly beneficial for addressing issues such as uneven skin tone, fine lines, and dullness. Additionally, citric acid acts as a pH adjuster in cosmetic formulations, helping to maintain the desired acidity levels for optimal stability and efficacy of the product.
