Science
Mechanism of Action
This ingredient operates on multiple fronts: as an emulsifier, it stabilizes oil-in-water or water-in-oil formulations, ensuring uniform dispersion. As a skin conditioner, its safflower oil component, rich in linoleic acid, is crucial for fortifying the epidermal barrier, promoting optimal cohesion of cells within the stratum corneum, and significantly reducing transepidermal water loss. Additionally, it contains phytosterols that actively capture and retain moisture, and exhibits antioxidant properties, contributing to a non-greasy, rich sensory experience in topical applications.
