Where does it go in my routine?

Cleanse first, then tone, then apply this serum to the whole face while skin is still slightly damp. Give it a few seconds to sink in before moisturizer. In the daytime, sunscreen goes on last, over everything else. If you use an essence, it belongs before the serum; heavier layers and facial oils belong after. Nothing in this order needs rushing.

Is it suitable for sensitive skin?

LANEIGE calls the formula hypoallergenic and dermatologist-tested, and lists it as suitable for sensitive skin. That said, it does contain fragrance, which some reactive skin would rather avoid. If yours is easily upset, patch test along the jaw for a few days before applying it all over, and introduce it on its own rather than alongside two other new products.

Does it contain fragrance?

Yes. Fragrance appears on the ingredient list, and the serum carries the light scent the Water Bank range is known for. Ingredient lists do change between production runs and markets, so if you are avoiding fragrance entirely it is worth reading the carton you receive. Anyone building a routine around a strict ingredient filter should go by that printed list rather than any copy online.

Is it too light for dry skin?

Not on its own terms. This is a water-based hydrating step, not a moisturizer, so drier skin will want something richer over it. Used that way it gives the routine an extra reservoir of water to work with, which often makes a cream feel more effective. In winter, very dry skin may prefer to apply it to damp skin and follow quickly with a balm.

What has LANEIGE measured for this serum?

LANEIGE has run both instrumental and consumer testing on this exact serum, covering immediate moisture, temporary moisture-barrier condition, elasticity, and how testers rated hydration, dryness relief, smoothness and radiance. Rather than repeat those numbers here, the Real Results section further down lists all seven alongside the testing each one came from. It is worth a look if you like seeing measurements before buying.

PRODUCT DETAILS

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.

Frequently asked questions

Can this serum replace my moisturizer?

It can on humid days or on skin that runs oily, but it is built as a hydration step underneath a moisturizer rather than instead of one. A serum this light delivers water without much occlusion, so most people still want a cream or lotion over the top to seal it in. If your face feels tight an hour later, that is the sign to add one back.
