Science
Mechanism of Action
This ester functions by combining the rich profile of unsaturated fatty acids, vitamins E and B, and essential minerals from sweet almond oil with the advanced moisturizing and emulsifying properties of Polyglycerin-4. On the skin, it acts as an effective emollient, promoting a soft and smooth texture. Furthermore, its surfactant and emulsifier role is crucial for creating stable and homogenous oil-in-water or water-in-oil emulsions, ensuring consistent delivery of active ingredients and enhanced skin barrier support through its refatting action.
