LANEIGE Water Bank Aqua Facial Serum — Hydrating K-Beauty Serum with AHA/BHA/PHA Exfoliation, Hyaluronic Acid & Ceramides (Daily)

LANEIGE Water Bank Aqua Facial Serum is a dual-action K-Beauty daily serum that lightly exfoliates while delivering deep, long-lasting hydration for smoother, plumper, glass-like skin.

Inspired by Korean glass-skin routines, this serum combines a gentle chemical exfoliant blend (AHA, BHA, PHA) with powerful humectants (Hyaluronic Acid, Polyglutamic Acid) and barrier-supporting ceramides. The formula targets uneven texture and flakiness without stripping moisture, leaving skin softer and visibly more luminous. Lightweight and fast-absorbing, it layers easily under moisturizers and sunscreen for daily use.

How does this serum gently exfoliate without irritating sensitive skin?

The exfoliation system uses a balanced mix of AHA to smooth surface texture, BHA to clear pores, and PHA for gentle renewal and added hydration. Because the acids are calibrated for daily use and paired with hydrating ingredients, the serum reduces rough patches while minimizing irritation risk.

• Tri-acid blend: AHA + BHA + PHA for multi-level exfoliation
• Formulated for daily layering with hydration actives
• Dermatologically tested and hypoallergenic for sensitive types

What hydration technologies are inside and how do they plump skin?

Hydration comes from multi-weight Hyaluronic Acid for immediate moisture, Polyglutamic Acid for prolonged water retention, and ceramides to reinforce the skin barrier so moisture stays put. Together these ingredients improve skin elasticity and reduce the appearance of dryness and fine flaking, creating a visibly plumper surface.

• Multi-weight Hyaluronic Acid for layered hydration
• Polyglutamic Acid for longer-lasting moisture retention
• Ceramides to strengthen the lipid barrier and lock in hydration

How quickly will I see smoother, glowing skin?

Many users notice immediate improvement in texture and reduced flakiness after the first application thanks to the exfoliating and humectant combination. Over consistent daily use, the formula aims to increase visible radiance and sustain moisture for a glassy, healthy-looking finish.

• Instant texture smoothing and moisture boost after one use
• Ongoing improvements in radiance and luminosity with daily application
• Designed to work under makeup for a smoother application surface

How should I fit this serum into my routine?

Use the serum once daily—morning or evening—after cleansing and toning, then follow with moisturizer and sunscreen if used in the morning. A small pump spreads across face and neck; it absorbs quickly so it won’t pill under other products.

• Apply after cleansing and toning, before cream or oil
• Use SPF during the day when using exfoliating actives
• Compatible with most skin-type regimens; patch-test if very reactive

Who is this for: LANEIGE Water Bank Aqua Facial Serum is for anyone seeking a daily, lightweight product that smooths texture and delivers deep hydration—suitable for combination, dry, oily, and sensitive skin types that want a dewy, glass-skin finish without heavy creams. It's a practical step for people who want visible softening of flaky areas, reduced surface roughness, and sustained moisture under makeup or alone.
