ISNTREE Hyper Niacinamide 20 Serum

Description
Isntree Hyper Niacinamide 20 Serum (20ml) is a high-performance Korean brightening serum made to improve uneven skin tone, dullness, and the look of dark spots. With a strong 20% niacinamide base, it’s designed for people who want more visible tone-evening results, while still keeping the texture lightweight and fast-absorbing for easy daily layering.

To boost brightening and spot care, the formula also includes Arbutin to help improve the look of hyperpigmentation and Zinc PCA to support oil balance and clearer-looking pores. For hydration and comfort, it contains 10 layers of Hyaluronic Acid, giving instant moisture with a refreshing, non-sticky finish—great for combo and oily skin that still gets dehydrated.

How to use
1) After cleansing and toner, apply 2–3 drops to the face (or focus on dark spot areas).
2) Spread gently, then pat until fully absorbed.
3) Finish with moisturizer.

How often
- Start 3–4 times per week, then increase to daily if your skin tolerates it well (20% niacinamide can be strong for some people).

Morning tip
- Always finish with sunscreen, especially if you’re treating dark spots.
