Functions
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
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.
