Water Bank Blue Hyaluronic Acid Hydrating Serum

LANEIGE Water Bank Blue Hyaluronic Serum is the hydration step for anyone chasing that dewy, glass-skin look. It's a juicy, lightweight-cream texture that drops water deep into the skin and leaves it smooth and supple — and LANEIGE formulates it as hypoallergenic and dermatologist-tested, so sensitive skin is explicitly on the guest list.

Best for	Normal, dry, combination and oily skin
Targets	Dryness, dullness and uneven texture
Texture	Lightweight cream serum — juicy, not tacky
Key actives	Blue hyaluronic acid · peptides · green tea enzyme (lactobacillus ferment lysate)
When	Morning and night, after cleansing and toner
Tested	Hypoallergenic, dermatologist-tested, sensitive-skin suitable

What it actually does

• Delivers long-lasting hydration. Blue hyaluronic acid is the headline ingredient and LANEIGE's claim for it is hydration that holds rather than a quick surface fix.
• Uses a specific processing route. The brand ferments the hyaluronic acid with deep sea algae and puts it through a ten-step microfiltration process — that's where the "blue" name and the dewy, glowing finish claim come from.
• Adds peptides for firmness. Peptides are included to improve how firm the skin looks over time.
• Gently resurfaces. Green tea enzyme exfoliates lightly for a smoother-looking surface, and LANEIGE also credits it with strengthening the moisture barrier.
• Suits skin that reacts. It's dermatologist-tested and hypoallergenic, so it fits into a routine where most serums feel like a gamble.

Brand-reported results

From LANEIGE's own four-week independent consumer study on 40 women aged 18–35, measured after one week of use. Self-reported figures — results differ from person to person.

• 92% said it absorbed easily into the skin
• 90% said their skin felt smoother
• 87% said their skin felt more hydrated

How to use

1. Cleanse, then tone. This goes on after both, morning and evening.
2. Spread an even layer across the face. It's a serum step, so a thin, complete pass beats a thick patch.
3. Seal it with moisturiser so the hydration you just applied doesn't evaporate off.
4. Finish with SPF in the morning.

Questions

What makes the hyaluronic acid "blue"?

It refers to LANEIGE's processing: fermentation with deep sea algae followed by a ten-step microfiltration. The brand's claim is that this delivers hydration that lasts longer and reads as dewy rather than sticky.

Do I still need a moisturiser?

Yes. A serum delivers water and actives; a moisturiser is what keeps them from evaporating. Use both, serum first.

Will it feel heavy in Egyptian summer?

It's described as a lightweight cream, so most people find it manageable year-round. In peak heat, apply a thinner layer in the morning and keep the fuller application for night. Store it away from direct sun.
