Science
Mechanism of Action
Forms a continuous, breathable film on the skin surface that provides immediate physical smoothing of fine lines and a temporary tightening effect. Its polysaccharide structure binds water molecules to the skin, reducing trans-epidermal water loss while delivering gentle anti-inflammatory benefits through enhanced hydration.
