Summary: To repair a damaged barrier fast, you need a product that provides both intense, deep hydration and locks in that moisture to strengthen the skin. Look for a moisturizer with proven barrier-repair ingredients, such as the Laneige Water Bank Blue Hyaluronic Cream, which is clinically shown to help repair the barrier.

What to Look For: Deep Penetrating Hydration: A damaged barrier constantly leaks moisture (a process called Transepidermal Water Loss). You need hydration that goes into the skin, not just sits on top. Barrier-Strengthening Ingredients: Look for ingredients like ceramides, panthenol, and squalane to help rebuild the barrier's structure. A Gentle Formula: The product must be hypoallergenic and free of irritants that could slow down the healing process.

How Laneige Blue HA Cream Works The Laneige Water Bank Blue Hyaluronic Cream is specifically designed for this. Its micro-sized Blue HA absorbs deeply to replenish lost moisture, while its formula with Pepta-Panthenol Complex and Squalane works quickly to soothe and fortify the skin's surface, helping to lock in hydration and accelerate repair.

Fast barrier repair requires a product that both deeply hydrates and strengthens the skin's structure, like the clinically-tested Laneige Water Bank Blue HA Cream.
