numbuzin Hydrating Serum No.6 — Iceland Glacier Water 1.69 fl. oz., Multi-Weight Hyaluronic & Niacinamide

numbuzin No.6 Serum is a lightweight, intensely hydrating serum that delivers sheet-mask level moisture using 63% Iceland glacier water plus a multi-weight hyaluronic acid complex for immediate and lasting hydration.

Designed as a daily serum that mimics the replenishing effect of a sleeping mask, this formula targets dry, dull, and dehydrated skin types with fast-absorbing texture and a blend of humectants and niacinamide. The serum layers easily under creams or makeup, and clinical testing shows deep hydration benefits without a sticky finish. It’s part of Korea’s streamlined skincare approach—big moisture results in a small, easy step.

How quickly will I feel hydration after applying numbuzin No.6 Serum?

You should notice immediate skin plumping and a fresh, dewy surface right after application thanks to its watery, lightweight texture that absorbs quickly. The combination of glacier water and five-tier hyaluronic acid hydrates at different skin depths for both instant and sustained moisture.

• 63% Iceland glacier water for a fresh, mineral-rich base
• Five-layer hyaluronic acid complex targets surface and deeper hydration
• Non-greasy, fast-absorbing texture suitable for layering
• Clinically tested to penetrate and hydrate beneath the surface

Can this serum replace a sheet mask or overnight mask?

This serum is formulated to provide many of the same moisturizing benefits as a sleeping mask while being far more convenient for daily use. It won’t give the occlusive feel of a heavy overnight mask, but it achieves long-lasting moisture and helps balance skin for up to 48 hours when used regularly.

• Sheet-mask level hydration in an easy serum format
• Ideal for mornings or lazy evenings when you skip masks
• Maintains skin moisture balance without heavy residue
• Pairs well with thicker creams if extra sealing is desired

Is numbuzin No.6 Serum suitable for my sensitive or acne-prone skin?

The formulation is lightweight and non-comedogenic, using soothing glacier water and niacinamide to help tone and strengthen the skin barrier. As with any active-packed product, patch testing is recommended if you have highly reactive skin or are introducing niacinamide for the first time.

• Niacinamide supports barrier resilience and clarity
• Gentle, watery texture reduces pore-clogging risk
• Clinically tested for deep hydration across skin types
• Patch test advised for very reactive skin

How should I incorporate this serum into my skincare routine?

Apply after cleansing and toning, while skin is slightly damp, to maximize absorption of humectants. Follow with your moisturizer or facial oil to lock in the multi-layer hydration, or use a richer night cream for extra barrier support.

• Use daily, morning and/or night on cleansed skin
• Press gently until absorbed; layer moisturizer after
• Works under sunscreen and makeup without pilling
• Good as a hydrating step before heavier creams or masks

Who is this for: numbuzin No.6 Serum is ideal for anyone with dry, dehydrated, or dull skin seeking a simple, fast-absorbing product that delivers deep hydration without heaviness. It’s also a practical choice for busy routines—people who want sheet-mask level results with a serum’s convenience, and for those looking to add niacinamide and multi-weight hyaluronic acid to their regimen without extra steps.
