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.

At low concentrations, citric acid is generally well-tolerated. However, higher concentrations used for exfoliation may cause irritation, so patch testing is recommended for sensitive skin.
Does citric acid make skin more sensitive to the sun?
Yes, like other AHAs, citric acid can increase skin's sensitivity to the sun. It is crucial to use sunscreen daily when using products containing citric acid.
