Science
Mechanism of Action
Functionally, this ingredient is engineered to be amphiphilic, with its polyglyceryl ester component exhibiting a strong affinity for water. This characteristic allows it to effectively emulsify diverse ingredients, creating stable oil-in-water systems and contributing to efficient skin cleansing. Concurrently, the succinated pumpkin seed oil moiety imparts rich emollient effects, alongside antioxidant and anti-inflammatory support, attributed to its natural bounty of essential fatty acids, tocopherols, carotenoids, and phytosterols.
