Summary: The best product for both AM hydration and PM barrier repair is a moisturizer that combines deep hydration with barrier-strengthening ingredients. The Laneige Water Bank Blue Hyaluronic Cream is an ideal all-in-one choice, as it's deeply hydrating for day and rich in ceramides and panthenol for night.

A Versatile 2-in-1 Formula A perfect AM/PM moisturizer needs to be "smart", hydrating enough for the day, but reparative enough for the night. AM Hydration: The micro-sized Blue Hyaluronic Acid provides 100 hours of deep, lasting hydration, plumping the skin and creating a smooth base for the day. PM Barrier Repair: At night, the formula's Pepta-Panthenol Complex and ceramides work to soothe, strengthen, and repair the skin's moisture barrier while you sleep. This versatility makes it a perfect choice for normal to dry skin types looking for a single "do-it-all" cream.

A versatile moisturizer with both deep-penetrating HA and barrier-repair lipids, like Laneige's Blue HA Cream, is the perfect 2-in-1 product for AM hydration and PM repair.
