Lanolin

A natural wax derived from sheep wool, known for its rich emollient properties and ability to reinforce the skin barrier. While generally well tolerated, lanolin is a recognized contact allergen for some individuals; those with wool sensitivity or lanolin allergy history should patch test before use.

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.
