Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Locks In Moisture
Traditional Use
A complex synthetic ester developed in modern cosmetic chemistry by chemically modifying macadamia oil with polyglycerols and behenic acid. This compound has no traditional use history and exists solely for 20th-century cosmetic formulation purposes.
