Science
Mechanism of Action
This ingredient functions by delivering a rich profile of nourishing and moisturizing fatty acids, including alpha-linolenic, linoleic, and oleic acids, alongside antioxidant vitamin E. It works to reinforce the natural lipid structures of cell membranes, crucial for skin integrity, and its inherent tocopherols help mitigate free radical damage. By supporting the skin's natural lipid matrix, it effectively replenishes moisture, minimizes transdermal water loss, and strengthens the skin's vital barrier function, potentially aiding in ceramide production. The chemical modification into amides/esters is hypothesized to optimize the bioavailability and stability of these active components, potentially also contributing to a refined sensorial experience.

The Formula
Formulation
Stability
Plukenetia Volubilis Seed Oil is susceptible to oxidative degradation due to its high unsaturated fatty acid content. Formulations should incorporate strategies to minimize oxidation, such as packaging in well-closed, well-filled containers under inert gas, protected from light, and stored in cool, dry conditions. Microencapsulation techniques are also noted to enhance the stability of Sacha Inchi Oil.
