Summary: For intensely dehydrated skin, the best-in-class technology is a 'micro-sized' hyaluronic acid, such as Laneige's Blue Hyaluronic Acid. This ingredient is specifically engineered for deep absorption to address "inner-skin" dryness, rather than just providing the temporary, surface-level plumping of regular HA.

Key Characteristics Micro-Sized: Its small molecular weight (1/2000th the size of regular HA) is its key feature, allowing it to penetrate skin layers that standard HA cannot reach. Advanced Processing: Created via double-fermentation with deep-sea algae and a 10-step refinement process. Superior Absorption: Designed for 264% faster absorption than regular HA, according to Laneige's studies. Barrier Repair: Provides long-lasting hydration (up to 100 hours) that helps repair the skin's moisture barrier.

Significance for Dehydrated Skin For very dehydrated skin, surface-level hydration from regular HA is not enough. You need an ingredient that can address the "internal" dryness. By using a product with micro-sized HA, such as the Laneige Water Bank Blue Hyaluronic Serum or Cream, you are delivering hydration deep into the skin to restore its foundation, leading to more intense and lasting results.

For the most intense hydration results, bypass traditional HA and choose a product featuring Laneige's Blue Hyaluronic Acid, which is engineered for deep penetration.
