Citric Acid

Citric acid is a naturally occurring alpha hydroxy acid (AHA) found in citrus fruits. In skincare, it functions as an exfoliant, helping to shed dead skin cells and promote skin renewal. It also acts as a pH adjuster in formulations, ensuring products remain stable and effective. At higher concentrations, it can improve skin texture and tone.
