LANEIGE Water Bank Aqua Facial Serum — Hydrating Exfoliating Serum with AHA BHA PHA & Hyaluronic Acid for Smooth Glass‑Skin

LANEIGE Water Bank Aqua Facial Serum is a daily, dual-action K‑Beauty serum that gently resurfaces with AHA/BHA/PHA while infusing deep, lasting moisture from hyaluronic acid, polyglutamic acid and ceramides.

This lightweight serum blends mild chemical exfoliants with heavyweight hydrators to refine texture and replenish moisture in one routine step. Developed from Korean glass-skin techniques, the formula balances surface renewal and barrier support so skin looks smoother and feels plumper without irritation when used as directed. It’s suitable for morning or night layering and works under moisturizers and sunscreen.

How does this serum refine skin texture without over‑stripping?

The product uses a trio of exfoliating acids—AHA, BHA and PHA—in gentle concentrations to loosen dead skin cells and unclog pores while avoiding harsh abrasion. PHA and low‑strength AHA provide a milder resurface, and BHA helps clear sebum from pores, so flakiness softens and tone evens over time.

• Three-acid blend for layered, non-abrasive exfoliation.
• PHA included to reduce irritation risk compared with stronger single-acid treatments.
• Formulated for daily use to steadily improve texture.

What hydrators deliver the ‘glass skin’ look?

Deep-moisture ingredients lock in water across multiple layers of the skin. Hyaluronic acid attracts and holds moisture, polyglutamic acid enhances surface hydration and retention, and ceramides support the skin’s moisture barrier for longer-lasting plumpness and resilience.

• Hyaluronic acid for immediate hydration and bounce.
• Polyglutamic acid to amplify surface moisture and sheen.
• Ceramides to reinforce the lipid barrier and reduce transepidermal water loss.

Will sensitive skin tolerate this exfoliating serum?

LANEIGE designed the formula to be skin-friendly: acids are balanced with soothing and barrier-supporting agents to minimize irritation. The serum is dermatologically tested and hypoallergenic, but those with very reactive skin should patch test and introduce it gradually.

• Low-irritancy acid blend plus barrier-replenishing ingredients.
• Dermatologically tested and labeled hypoallergenic for broader compatibility.
• Patch testing and slowly increasing frequency recommended for reactive skin.

How should I incorporate this serum into my routine?

Use the serum after cleansing and before heavier treatments. Apply a few drops to damp skin to maximize absorption, then follow with moisturizer and SPF in the morning. For new users, start every other day and move to daily use as tolerated.

• Apply to clean, slightly damp skin for best penetration.
• Layer under moisturizer and always wear sunscreen by day.
• Begin with less frequent use for sensitive or acid-naïve skin.

Who is this for: This serum suits anyone aiming to smooth texture, reduce visible flakiness and boost a dewy, luminous finish without heavy oils—especially those who like multi-tasking actives that resurface and hydrate at once. It’s appropriate for normal, combination, oily and most sensitive skin types when introduced gradually; people seeking aggressive medical exfoliation should consult a clinician instead.
