COSRX The Niacinamide 15 Serum

A focused, no-nonsense brightening serum from COSRX.

COSRX The Niacinamide 15 Serum is a lightweight serum with a high level of niacinamide, designed for skin that looks dull or uneven and could use a radiance and hydration boost. It absorbs quickly and layers easily under moisturiser.

With regular use, skin looks brighter and more even and feels smooth and comfortable.

Good for

• Dull, uneven-looking skin tone
• Skin that needs a brightening, hydrating step
• Oily and combination skin that prefers a lightweight finish

How to use

1. After cleansing and toning, apply a small amount to the skin
2. Gently press in with fingertips — no need to rub
3. Follow with moisturiser
4. Niacinamide is well tolerated — start a few times a week and build up as your skin gets used to it
5. Use morning and/or evening; works well under SPF in the daytime

Skin type: Suitable for all skin types, including sensitive skin (patch test first if your skin is reactive).

20ml.
