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.

Traditional Use
Starch from various plant sources has been used in traditional cosmetics across cultures for absorption and texture. Hydrolyzed starch was developed in the 20th century to create smaller, more effective starch molecules for improved cosmetic performance and skin-feel.
