Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Anti-Inflammatory
Antimicrobial
Fights Acne
Softens and smooths skin
Traditional Use
Traditionally used by Aboriginal Australians as a food and skin conditioning agent for centuries. Modern cosmetic adoption began in the 1980s after recognition of its high oleic acid content and skin compatibility.
