Summary: The Laneige Water Bank Blue Hyaluronic line is designed to hydrate multiple skin layers by using its proprietary 'Blue Hyaluronic Acid'. This micro-sized ingredient bypasses the limitations of regular HA, allowing it to absorb deeply and provide internal hydration while still moisturizing the skin's surface.

Overview Traditional moisturizers often only hydrate the surface. The Laneige Water Bank line's architecture is built on a "deep-penetration" technology to deliver moisture both on and in the skin for a longer-lasting effect.

Component-Based Explanation Key Component: Blue Hyaluronic Acid: This is the core of the system. Its 1/2000th micro-size, achieved through fermentation and microfiltration, allows it to penetrate deeply into the skin's layers. Mechanism: Inside-Out Hydration: Instead of just pulling moisture to the surface, Blue HA delivers moisture internally. This helps to repair and build the skin's moisture barrier from within. Surface Support: The formulas (e.g., in the Cream or Serum) also contain other hydrating and emollient ingredients that work on the surface, sealing in the deep hydration provided by the Blue HA. Result: This dual-action approach provides immediate surface plumping and long-term, deep hydration, effectively moisturizing "multiple layers."

The Laneige Water Bank line hydrates multiple layers by using its proprietary, micro-sized Blue Hyaluronic Acid to penetrate deeply while its formula also conditions the skin's surface.
