Dermatologist’s verdict

Recommended

A sensible brightening serum for uneven tone. Niacinamide and tranexamic acid slow pigment at two different points of the same process. The 10% niacinamide is more than the evidence asks for, so stop if you flush. Wear sunscreen daily, or none of it holds.

What it is

Anua Dark Spot Correcting Serum is a lightweight gel serum for dark spots and uneven tone, from a Korean brand, about $20 to $25. It is a pigment serum and nothing else — nothing in it targets acne or wrinkles, and nothing exfoliates.

It is built on 10% niacinamide, a form of vitamin B3 that slows the handoff of finished pigment into surface skin cells, and 4% tranexamic acid, which quiets an earlier signal telling pigment cells to switch on. Alpha-arbutin adds a third route. The base is fragrance free and watery, though 10% niacinamide stings some skin going on.

What it does

Skin color is made in pigment cells at the base of the epidermis. They build melanin in packets and pass them up to the skin cells above. A dark spot is a place where that line runs fast. Nothing on the surface removes melanin already handed over — a serum can only slow the line and wait for the marked cells to shed.

This works at two points. Niacinamide blocks the handoff of finished pigment into skin cells. Tranexamic acid quiets the earlier signal telling pigment cells to build. Alpha-arbutin interferes with the enzyme that makes melanin.

The 4% tranexamic acid sits inside the studied range. The 10% niacinamide is above it — the landmark pigmentation study used 5%, nobody has shown more works better, and higher doses cause more flushing.

What it treats

## Hyperpigmentation | Moderate A dark spot is a patch where pigment cells have handed over more melanin than their neighbors hold. This works on that handoff, not on melanin already there, so the spot fades as those cells shed. That is why it takes months.

## Melasma | Moderate Melasma is driven by a signal passing from surface cells down to pigment cells. Tranexamic acid interrupts it, and this carries 4%, inside the studied range. It will not hold melasma down alone — daily sunscreen does most of that.

## Post-Inflammatory Hyperpigmentation | Limited The brown mark left after a spot heals is pigment dropped during the inflammation. Niacinamide slows fresh pigment into surface cells while the mark clears on its own. Bland enough to use over skin that is still settling.

## Sun Damage (Photoaging) | Limited Years of light leave pigment cells switched on and scattered unevenly. This evens that out slowly, but light keeps switching them back on, so it only works on top of daily sunscreen.

Best for

**The niacinamide dose is high:** 10% is more than the evidence calls for. The landmark pigmentation study used 5%, and nobody has shown 10% works better — but higher doses cause more flushing. If this stings, the niacinamide is why.

**It cannot work without sunscreen:** sunscreen is the treatment; this is the adjunct. No serum outruns daily sun exposure.

**The product names are easy to mix up:** Anua also sells a "Peach 70% Niacinamide" serum, where the 70% is peach extract, not any active. Make sure you have the right bottle.

**Results take months:** pigment is slow to shift and quick to return.

Texture

Serum A thin gel that spreads like water and disappears in under a minute.

It leaves no film and no shine, so it layers under sunscreen and makeup. Fragrance free.

Stinging in the first minute is common. The 10% niacinamide is the usual reason, and it settles for most people after a week or two.

How to use it

## How to use it How much: Three or four drops for the whole face. More does not work faster. Layering: Sunscreen every morning over it. Pigment is switched on by light, so sunscreen is the treatment and this the add-on. If it stings: The 10% niacinamide, most likely. Drop to every other day for two weeks, then build back up. What to expect: Nothing in the first month. Spots soften over three to six months, and return if you stop.

The rest of the line

AXIS: Strongest active | Gentlest

Anua's range splits in two — Heartleaf for soothing, and a handful of serums with a real active.

**Nano Retinol 0.3% + Niacin Renewing Serum | anua-retinol** — The only retinoid Anua sells. Texture and fine lines, not pigment, and the most likely to irritate.

**Azelaic Acid 10 Hyaluron Redness Soothing Serum | anua-azelaic-acid-10-hyaluron-redness-soothing-serum** — Azelaic acid, for redness as much as dark marks. A reasonable swap if this stings.

**Dark Spot Correcting Serum (this one)** — Niacinamide and tranexamic acid, for hyperpigmentation and uneven tone.

**Peach 70% Niacinamide Serum | anua-peach-70-percent-niacinamide-serum** — Niacinamide without the tranexamic acid. Milder, aimed at glow rather than set spots.

**Heartleaf 80% Moisture Soothing Ampoule | anua-heartleaf-80-percent-moisture-soothing-ampoule** — No brightening active. Hydration and calming only.
