Science
Mechanism of Action
This seed butter functions primarily as an emollient and moisturizer, owing to its high content of oleic and palmitic acids, which are crucial for preventing transepidermal water loss. Its efficacy extends to antioxidant activity, protecting skin from free radical damage, and anti-inflammatory and antimicrobial actions, largely attributed to limonoids such as Trichilin. These combined effects contribute to soothing irritation, supporting barrier function, and balancing natural oil production.
