Citric Acid
What It Is
Citric Acid is an organic acid naturally found in citrus fruits and widely used in cosmetic formulations.
Functional Role
It primarily functions as a pH adjuster to help maintain formulation stability.
Skin-Relevant Properties
At appropriate levels, citric acid may also contribute to mild surface refinement.
Interesting Fact
Commercial citric acid used in cosmetics is typically produced through fermentation rather than extracted directly from fruit.
