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.
Skin Protecting
Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.
Nourishes & Protects
Traditional Use
Developed in the 19th century from brewer's yeast byproducts. Historically used in nutritional contexts before adoption in cosmetics for its B vitamins, amino acids, and skin-conditioning properties.
