Science
Mechanism of Action
This ingredient operates by delivering exogenous lipids to the stratum corneum, effectively filling gaps within intercorneocyte clusters to fortify the skin barrier. It creates a lightweight, hydrophobic, and non-occlusive film on the skin's surface, significantly reducing transepidermal water loss. Additionally, it improves the sensorial experience of formulations by enhancing product glide and imparting a soft, smooth skin feel, while also aiding in the solubilization and uniform distribution of oil-soluble actives and pigments.
