Cos De Baha Niacinamide 20% + Zinc 4% Serum 30ml (NZ)

Cos De Baha Niacinamide 20% + Zinc 4% Serum (NZ) is a lightweight, fast-absorbing water serum from Korean skincare brand Cos De Baha, positioned as a high-strength, multi-tasking treatment for oily, blemish-prone, and uneven skin.

Suitable for both AM & PM routines, this serum sits after cleansing and toning, before moisturiser. Its quick-drying, non-greasy finish makes it an easy layer under SPF in the morning or heavier actives at night.

At its core, 20% Niacinamide (Vitamin B3) regulates oil, strengthens the skin barrier, and fades pigmentation, while 4% Zinc PCA controls sebum production and fights acne-causing bacteria. Sodium Hyaluronate and Glycerin deliver dual-layer hydration, Arbutin targets dark spots by inhibiting melanin production, and Allantoin soothes inflammation and supports barrier repair. Antioxidant-rich Camellia Sinensis Leaf Extract and Caffeine round out the formula with added protection against environmental stressors.

• Visibly minimises enlarged pores & refines skin texture with consistent use.
• Regulates excess oil and reduces breakouts, making it ideal for acne-prone skin types.
• Fades hyperpigmentation, dark spots, and post-blemish marks for a more even, luminous complexion.
• Hydrates and soothes while reinforcing the skin barrier, reducing redness and sensitivity over time.

How to Use: After cleansing and toning, apply a small amount to the face, neck, and décolletage and allow it to absorb fully. Follow with a moisturiser to lock in hydration. Use morning and evening. Perform a patch test on the neck before first use, as the high niacinamide concentration may cause sensitivity in reactive skin.
