Alanine

A non-essential amino acid that occurs naturally in skin and is used in cosmetics as a humectant and skin-conditioning agent. It has an established safety record with no reported concerns at typical usage 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.
