Science
Mechanism of Action
This ingredient primarily functions by softening and smoothing the skin's surface, acting as an effective emollient. As a derivative of Evening Primrose Oil, it provides a valuable supply of linoleic acid (typically 66-76%) and gamma-linolenic acid (GLA, approximately 7-12%). These critical fatty acids serve as precursors for anti-inflammatory eicosanoids and are essential for stabilizing the epidermal keratinization process. They contribute directly to improving skin hydration, minimizing trans-epidermal water loss (TEWL), and enhancing skin elasticity and firmness. GLA specifically supports the reconstruction of the skin's vital lipid barrier, which in turn boosts moisture retention, offers protection against external aggressors, and provides anti-inflammatory benefits that may also aid in regulating sebum production.
