Most serums just add surface moisture that disappears quickly, but this one delivers hydration that actually reaches where dehydration starts. Seven different molecular weights of hyaluronic acid work at every skin layer - some absorb instantly for immediate plumping while others penetrate deeper for lasting moisture. Sea buckthorn oil provides vitamins A, C, and E that protect your skin barrier and help it hold onto hydration longer. This doesn't just temporarily plump your skin but actually teaches it to stay hydrated on its own for skin that feels soft and comfortable all day.
