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.
Locks In Moisture
Traditional Use
Complex polymer developed in the late 20th century combining silicone technology with linoleic acid from plant oils. Designed to provide both skin conditioning and protective barrier properties while maintaining a smooth, non-greasy feel.
