Oleic Acid

A monounsaturated fatty acid found naturally in plant and animal oils, used as an emollient and emulsifier in skincare products. Oleic acid is well tolerated by most people and supports skin barrier function, though those with oleic acid sensitivity should avoid or patch test first.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
