Your skin can feel moisturized on the surface but still be dehydrated underneath, which is why most creams only give temporary relief. This uses seven different molecular weights of hyaluronic acid: large molecules create a moisture film while smaller ones penetrate deeper where dehydration actually starts. Dimethicone locks everything in while vitamins C and E prevent the cellular damage that makes skin lose water faster. This creates a moisture delivery system at every level, so your skin stays plump for hours instead of minutes.
