A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

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

A contemporary cosmetic ingredient produced by lysing yeast cells and filtering the resulting liquid. Developed to provide soluble yeast metabolites without particulate matter in skincare products.
