Science
Mechanism of Action
This ingredient is formed through the transesterification of Sclerocarya Birrea Seed Oil (Marula oil) and PEG-8. The Marula oil fraction acts as a potent emollient and moisturizer, rich in fatty acids such as oleic and palmitic acids, which mirror the skin's natural lipid composition, potentially aiding absorption into the stratum corneum. It also offers antioxidant protection by neutralizing free radicals, leading to soothed, softened, and improved skin texture. Concurrently, the PEG-8 component is a water-soluble humectant and solubilizer, crucial for seamlessly integrating the oil-derived benefits into water-based skincare systems.
