Dealing with dark spots, post-acne marks, or uneven skin tone? Finding the best niacinamide serum for hyperpigmentation on Amazon can be overwhelming with so many options. After thorough research and real-user feedback, the Anua Niacinamide 10% + TXA 4% Serum stands out as a top performer in 2026 — especially for beginners and those seeking visible brightening without irritation.
This powerful yet gentle Korean serum combines high-potency Niacinamide with Tranexamic Acid (TXA) to target hyperpigmentation effectively. In this in-depth review, we’ll cover everything you need to know.
Why Anua Niacinamide 10% + TXA 4% is the Best Niacinamide Serum for Hyperpigmentation on Amazon
Hyperpigmentation occurs due to excess melanin production from sun exposure, acne, or inflammation. Niacinamide (Vitamin B3) inhibits melanin transfer while strengthening the skin barrier. Tranexamic Acid further brightens by blocking pigment pathways.
The Anua formula delivers **10% Niacinamide** and **4% TXA** — a potent combination rarely found at this strength and price on Amazon. It’s lightweight, fast-absorbing, and suitable for most skin types, including sensitive skin.
Key Ingredients and How They Fight Hyperpigmentation
- Niacinamide 10%: Reduces dark spots, evens tone, minimizes pores, and boosts hydration.
- Tranexamic Acid 4%: Clinically shown to fade melasma and post-inflammatory hyperpigmentation.
- Supporting botanicals for soothing and antioxidant protection.
This duo makes it one of the most effective niacinamide serums for stubborn dark spots available on Amazon.
Benefits You Can Expect
- Visible reduction in dark spots and hyperpigmentation within 4–8 weeks
- Brighter, more even complexion
- Improved skin texture and reduced redness
- Strengthened skin barrier (less irritation from other actives)

Many Amazon reviewers praise it for fading acne marks and sun spots without the purging or dryness common in stronger treatments.
How to Use Anua Niacinamide 10% + TXA 4% Serum (Beginner Routine)
- Cleanse face (use Anua Heartleaf Cleansing Oil as first step for best results).
- Apply 2–3 drops of the serum to face and neck.
