ANUA – Niacinamide 10% + TXA 4% Dark Spot Removing Serum (30ml)

Looking for a targeted anua serum that genuinely fades dark spots? The Niacinamide 10% + TXA 4% Dark Spot Removing Serum (30ml) is Anua’s answer to a results-led Korean treatment serum, engineered to deliver repeatable brightening and hydration without unnecessary fillers. Below we cover exactly what this anua serum does, its hero ingredients, how to layer it in your K-Beauty routine, who it suits best, and what to expect after the first bottle.

Why choose this anua serum for dark spots?

This serum is purpose-built as a brightening treatment for modern K-Beauty routines. It sits after toner and before moisturiser, working to reduce hyperpigmentation, boost radiance, improve hydration and smooth uneven texture over time.

Compared to mass-market Western equivalents, Anua leans on expertise-led Korean formulation, lighter textures and a strict focus on barrier-safe actives — making it a standout choice for anyone dealing with post-acne marks, sun spots or dullness.

• Dual-active brightening — 10% niacinamide combined with 4% tranexamic acid (TXA) targets melanin production at two pathways simultaneously.
• Clean, cosmetically elegant formula — lightweight feel, fast absorption, no sticky residue and no harsh fragrance.
• Routine friendly — layers cleanly with essences, eye serums, masks and SPF without pilling.
• Authentic UK supply — sourced directly from Anua or an authorised UK distributor, with an English INCI label on every bottle.

Key ingredients in this anua serum

Korean cosmetic chemistry delivers the best results when actives are layered intelligently and dosed effectively. The hero ingredients in this formulation are:

• Niacinamide 10% — inhibits melanosome transfer to skin cells, visibly reducing dark spots, minimising pores and strengthening the skin barrier.
• Tranexamic acid (TXA) 4% — a well-researched brightening active that reduces melanin synthesis, particularly effective on stubborn post-inflammatory hyperpigmentation (PIH).
• Hyaluronic acid & glycerin — humectant hydration anchors that draw moisture into the skin and keep it there throughout the day.
• Peptides & plant ferments — support skin renewal, elasticity and a healthy microbiome environment.

According to the INCI Decoder ingredient reference for niacinamide, concentrations at or above 5% are considered effective for brightening and barrier repair — making the 10% level in this anua serum a visibly meaningful dose.

The full INCI list is printed in English on every UK order so you can verify every ingredient before use.

How to use the anua serum step by step

1. Cleanse — oil cleanse first if you wear SPF or makeup, then follow with a gentle water-based cleanser.
2. Tone — a hydrating toner rebalances skin pH and primes the skin to absorb actives more effectively.
3. Apply the serum — dispense 3–4 drops onto clean, slightly damp skin. Press gently across the cheeks, forehead and chin.
4. Pat, do not rub — pressing the formula into skin rather than rubbing avoids friction that can compromise actives.
5. Seal — follow with a moisturiser at night or a broad-spectrum SPF in the morning. Daily SPF use is essential when using any brightening active.

For best results, use this anua serum twice daily — morning and evening — consistently for at least 4–8 weeks before assessing dark spot improvement.

Who the anua serum suits best

• Anyone with dark spots, post-acne marks, melasma or uneven skin tone looking for a proven active treatment.
• K-Beauty fans building a layered routine who need a clean, well-tolerated brightening step.
• People with oily, combination, normal or mild-sensitivity skin types. (If your skin is very sensitive, patch-test first.)
• Shoppers who value ingredient transparency and an English-labelled product shipped authentically to the UK.
• Customers planning to layer this with other products from the Anua skincare range at ELYSORA.

Where the anua serum fits in a full K-Beauty routine

This serum sits at the treatment stage of a Korean multi-step routine. A typical evening order looks like this:

1. Oil cleanse
2. Water-based cleanse
3. Hydrating toner
4. Treatment serum (this anua serum)
5. Eye care
6. Moisturiser or sleeping mask

In the morning, swap the sleeping mask for a generous layer of broad-spectrum SPF 30+ to protect the skin and maximise the brightening results. Pair it with a complementary K-Beauty serum from our range if you want to address additional concerns such as hydration or firming.

Frequently asked questions about the anua serum

Is this anua serum suitable for sensitive skin?
The formula avoids harsh fragrance and most users with normal-to-sensitive skin tolerate it well. Patch-test on the inside of the arm or behind the ear for 24 hours before applying to the full face. If you are new to niacinamide at 10%, introduce it gradually — every other day for the first two weeks.

How long does one 30ml bottle last?
With twice-daily use most customers finish one bottle in 4–6 weeks. With once-daily use expect 8–10 weeks of use. Store the bottle away from direct sunlight and heat to preserve the active ingredients.

Can I use this with vitamin C or retinol?
Niacinamide layers well with most actives including vitamin C derivatives and low-strength retinoids. If you use a direct ascorbic acid vitamin C, stagger the application (vitamin C in the morning, this anua serum in the evening) to avoid any potential interaction at very low pH.

Can I return it if I do not like it?
Unopened items can be returned within 14 days of receipt. Opened skincare cannot be returned unless the product is faulty or not as described. Full details are on our Refund & Returns Policy page.

How fast is worldwide delivery?
UK Tracked 48 takes 2–4 working days and is free on orders. UK Next Day is available when ordered before 14:00 GMT. See the Delivery & Payment page for all options including EU and international.
