LANEIGE Water Bank Aqua Facial Serum — AHA BHA PHA exfoliating & hydrating serum with hyaluronic acid and ceramides

Built around the Korean glass-skin tradition, this lightweight serum pairs mild chemical exfoliants with powerful hydrators to smooth texture, reduce visible flakiness, and restore a luminous, glassy finish. The formula combines multi-acid resurfacing with moisture‑retaining molecules and skin‑barrier lipids so you get both a refined surface and plumped‑up hydration in one step.

How does this serum gently exfoliate without over‑drying?

Instead of a single strong acid, the serum blends AHA, BHA, and PHA to provide layered exfoliation: AHAs loosen surface dead cells, BHA clears pores and PHA offers mild renewal for sensitive skin. That trio reduces roughness while minimizing irritation, making the action feel resurfacing rather than stripping.

• Multi-acid blend: AHA for surface smoothing, BHA for pore refinement, PHA for gentle renewal
• Balanced concentrations to avoid excessive flaking or redness
• Suitable for daily use when paired with sun protection

What hydration technologies are inside and how do they work?

The serum uses a combination of hyaluronic acid, polyglutamic acid, and ceramides to hydrate at multiple levels and support the skin barrier. Hyaluronic acid binds surface and deeper moisture, polyglutamic acid locks in water for prolonged plumpness, and ceramides help repair and seal the skin’s protective layer.

• Hyaluronic acid: immediate plumping and surface smoothing
• Polyglutamic acid: long-lasting moisture retention for up to hours
• Ceramides: restore barrier strength and reduce trans-epidermal water loss

What results can I expect and how quickly will I see them?

Users typically notice a reduction in visible flakiness and a softer skin feel after the first application, with progressively smoother texture and more apparent radiance over weeks. Continued use helps maintain a hydrated, glassy appearance while the gentle exfoliation refines tone and touch.

• Immediate: reduced roughness and increased surface hydration
• Short term: diminished flakiness and plumper skin after a few uses
• Ongoing: sustained glow and improved skin evenness with regular application

Can people with sensitive or combination skin use this serum?

The formula is designed to be tolerant: PHA provides a milder exfoliation path and ceramides plus hydrating polymers help soothe and strengthen the skin. Still, patch testing is recommended if you have very reactive skin, and always follow with SPF in daytime routines.

• Dermatologically tested and hypoallergenic formulation
• PHA inclusion reduces potential irritation versus stronger single-acid products
• Layer with moisturizer and daily sun protection for best results

Who is this for: LANEIGE Water Bank Aqua Facial Serum is suited to anyone seeking smoother texture and a hydrated, luminous finish—especially those who want gentle chemical exfoliation without compromising moisture. It works well for dry, normal, combination, and many sensitive types when introduced gradually into an existing skincare routine. Ideal as a morning or evening step before moisturizer and sunscreen (day), it pairs with serums or creams aimed at brightening or barrier repair for a comprehensive glow-focused regimen.
