ISNTREE HYPER NIACINAMIDE 20 SERUM 20ml

Isntree Hyper Niacinamide 20 Serum is a high-strength brightening treatment built on 20% niacinamide for dull tone, visible pores and excess oil. Arbutin and zinc PCA reinforce the tone- and oil-focused formula, while a ten-form hyaluronic-acid complex offsets the drying feel of a high-percentage active.

Key Benefits

• Niacinamide at 20% supports a brighter, more even-looking complexion.
• Arbutin complements niacinamide's tone-evening effect.
• Zinc PCA helps balance excess oil and the look of enlarged pores.
• Ten hyaluronic-acid forms replenish hydration alongside the active.
• Adenosine supports a smoother, firmer-looking finish.

When to Use

Use once daily to start — morning or evening, after toner and before moisturizer — increasing to twice daily only if skin tolerates the high niacinamide concentration well. Wear sunscreen every morning.

How to Use

Apply 2–3 drops or a small amount to clean, toned skin. Spread over the face and neck, pat until absorbed, then follow with moisturizer.

Key Ingredients

• Niacinamide (Vitamin B3) — the documented 20% concentration, a brightening and barrier-supporting active.
• Arbutin — a plant-derived tone-evening ingredient.
• Zinc PCA — an oil-balancing, pore-focused ingredient.
• Hyaluronic Acid Complex — ten documented moisture-binding forms.
• Adenosine — a wrinkle-care active.
• Dipotassium Glycyrrhizate — a licorice-root-derived soothing ingredient.

Precautions

For external use only. Patch test before first use — a high 20% niacinamide concentration can cause temporary flushing, tingling or redness in sensitive skin, especially on first use. Introduce gradually, avoid direct eye contact, and discontinue use if persistent irritation occurs.
