Phytosterols

Plant-derived sterols that function as emollients and barrier-supporting ingredients found naturally in many botanical sources. They are well tolerated in cosmetic formulations with no known safety concerns at typical use levels.

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.
