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.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Boosts collagen production
Reduces fine lines
Traditional Use
Soybean polypeptides are derived from soy protein and have been used in Asian cosmetics for decades as moisturizing and skin-conditioning agents; developed to harness the protein-rich nutritional profile of soybeans.
