Hyaluronic Acid
Helps hydrate and visibly plump the skin.
LANEIGE Water Bank Blue Hyaluronic Serum is a 50 mL hydrating serum with a juicy, quick-sinking texture that sits between your toner and your moisturizer. Use it over the whole face after cleansing, morning and evening, on days when skin runs short on water and looks a little flat. It settles to a dewy finish rather than a tacky film.
Its hydration comes from a low-molecular-weight hyaluronic acid that LANEIGE calls Blue Hyaluronic Acid, backed by beta-glucan, betaine and a xylitol-derived humectant blend. Those ingredients pull water into the outer layers and help hold it there, while a peptide and vitamin E round out the list. Fragrance is included, so read the carton if you avoid it.
It works for normal, dry, combination, oily and sensitive skin, and the thin texture layers under sunscreen or makeup without pilling. LANEIGE puts the formula through hypoallergenic and dermatologist testing. If your skin drinks up moisture and still feels tight by mid-morning, this is the step that keeps everything after it comfortable.
At 50 mL this is the full-size bottle, and it is the lightest leave-on step in the Water Bank range — a serum rather than a cream, so pair it with the moisturizer your skin already likes.
