Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum 50ml

Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum (KPOP Demon Hunters Edition) 50ml is a Korean serum built around an azelaic complex, formulated to calm the look of redness, even out skin tone and support blemish-prone skin while keeping the texture light.

Its azelaic system is led by Disodium Azelate in second position, with free Azelaic Acid at seventh — a distinction explained in detail below, because it changes what you should expect. Betaine Salicylate at ninth adds a second, exfoliating active.

Around those sit Panthenol, Allantoin, Beta-Glucan, Aloe Vera, a full Centella Asiatica complex, Neem leaf and flower extracts, green tea leaf water, Sodium Hyaluronate, Niacinamide and Zinc PCA. The formula contains no added fragrance.

Why Choose Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum?

Redness, post-blemish marks and uneven tone tend to arrive together, and most products that treat them aggressively make the redness worse before they make it better.

Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum takes a gentler route: a water-soluble azelaic complex rather than a high-strength azelaic cream, paired with a substantial soothing system.

That soothing side is genuinely well stocked — Panthenol at sixth, Allantoin, Dipotassium Glycyrrhizate, Beta-Glucan, Aloe Vera, a seven-part Centella Asiatica complex, neem leaf and flower, and green tea leaf water. Sodium Hyaluronate and Glycerin handle hydration; Niacinamide and Zinc PCA support tone and oil balance.

The formula carries no added fragrance, which matters for anything aimed at reactive skin.

It is a cosmetic serum. It is not a treatment for rosacea, eczema or any medical condition, and the section below explains honestly what the number in its name does and does not mean.

What “Azelaic Acid 10” Actually Means

This is the most important thing to understand before buying, and most listings will not tell you.

Two Different Ingredients

The formula contains two azelaic ingredients, in two very different positions:

Ingredient	Position	What It Is
Disodium Azelate	2nd	The sodium salt of azelaic acid — water-soluble
Azelaic Acid	7th	Free azelaic acid, the classic dermatological form

Why the Salt Is Used

Free azelaic acid barely dissolves in water. That is why genuine 10% to 20% azelaic acid products are thick creams and gels — the acid has to be suspended rather than dissolved.

A light, pourable serum like this one cannot hold that much free azelaic acid. Disodium azelate dissolves easily, which is what makes a serum texture possible at all.

What That Means for the Number

The “10” in the product name almost certainly refers to the combined azelaic complex — not to 10% free azelaic acid. Based on the ingredient order, the great majority of it is disodium azelate.

Anua does not publish a separate figure for free azelaic acid, and it cannot be worked out from an ingredient list. We are not going to state one.

Is the Salt as Good?

It is not the same thing, and it should not be described as such. The large body of dermatological evidence behind azelaic acid was built on free azelaic acid at 15% to 20%. Disodium azelate is a related but distinct molecule with far less published work behind it.

So Should You Buy It?

Yes, if you want what this actually is: a light, fragrance-free, well-soothed serum with an azelaic complex, suited to redness-prone and blemish-prone skin that would not tolerate a high-strength azelaic cream.

No, if you are looking for the azelaic acid your dermatologist means. For that, you need a prescription-strength 15% to 20% free azelaic acid preparation, and your doctor is the person to ask.

We would rather lose a sale than have you buy this expecting the other thing.

How Azelaic Acid Works

What It Does

Azelaic acid is unusual in acting on three concerns at once: it calms inflammatory pathways in the skin, it normalises the way surface cells shed inside pores, and it interferes with pigment production. That combination is why it appears in products for redness, blemishes and dark marks alike.

On Pigmentation

It acts selectively on overactive pigment-producing cells, which is why it is associated with post-blemish dark marks specifically rather than general lightening.

On Redness

Its anti-inflammatory action is why it appears in redness-focused formulas — though persistent facial redness is often rosacea, which is a medical condition needing proper diagnosis.

How Long It Takes

Several weeks for redness and blemishes; two to three months or more for post-blemish marks. Nothing visible happens in the first fortnight.

What It Will Not Do

It will not remove indented or raised acne scars — those are structural and need professional procedures. It will not change your natural skin colour, and it will not cure acne or rosacea.

This Serum Has Two Actives, Not One

The name mentions azelaic acid and hyaluron. It does not mention the second active, so we will.

Betaine Salicylate — 9th

Betaine salicylate sits ninth in the ingredient list — above the glycerin. It is the salicylic-acid-related ingredient widely used in Korean skincare as a BHA, typically at levels where it does real exfoliating work.

Why This Matters

It means this is a two-active serum: an azelaic complex plus a BHA — in a product whose name says “redness soothing”.

For blemish-prone skin, that combination is a genuine strength. The BHA works inside pores while the azelaic complex works on redness and marks.

For reactive skin, it is a reason to go slowly. Two exfoliating-type actives in one bottle is more than the gentle name suggests, and it is why the manufacturer’s own advice is to start at one or two drops, once or twice a week.

A Note on Propylene Glycol

Propylene Glycol sits third and Dipropylene Glycol fourth. These are ordinary, widely used humectants and solvents, but a small number of people are sensitive to propylene glycol specifically. At third position it is worth knowing about in a product you are buying to calm your skin.

Which Is Why Patch-Testing Is Not Optional Here

Two actives, high glycols, and skin that is already reactive. Patch-test on the inner forearm for several days before putting this on your face.

9 Key Benefits of Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum

• Water-Soluble Azelaic Complex: Disodium Azelate at second position, with free Azelaic Acid at seventh.
• Serum Texture: Light and pourable, where high-strength azelaic products are thick and heavy.
• Added BHA: Betaine Salicylate at ninth supports blemish-prone skin inside the pores.
• Deep Soothing System: Panthenol (6th), Allantoin, Dipotassium Glycyrrhizate, Beta-Glucan and Aloe Vera.
• Full Centella Complex: Three centella extracts plus madecassoside, asiaticoside, asiatic acid and madecassic acid.
• Neem and Green Tea: Neem leaf and flower extracts plus green tea leaf water.
• Tone Support: Niacinamide and the azelaic complex both act on uneven tone.
• Oil Balance: Zinc PCA supports oily and combination skin.
• No Added Fragrance: No fragrance or parfum anywhere in the formula.

Redness and Uneven Skin Tone

What the Serum Targets

The appearance of redness linked to dryness, over-cleansing, weather and external irritation — the everyday kind that comes and goes.

The Soothing Side Is Real

Panthenol at sixth is a strong placement, and it is backed by allantoin, dipotassium glycyrrhizate, beta-glucan, aloe vera and the full centella complex. For a product aimed at calming skin, this is a properly built soothing system rather than a token one.

When It Is Not the Answer

Persistent redness across the cheeks and nose, flushing, visible vessels or bumps is often rosacea — a medical condition that needs a doctor, not a cosmetic serum. Please get it looked at rather than working through bottles.

On Uneven Tone

The azelaic complex and niacinamide both act on uneven pigmentation, by different routes. Expect gradual improvement over months, and only with daily sunscreen — without it, new pigment forms faster than this can fade the old.

Will It Whiten Skin?

No. Azelaic acid acts selectively on overactive pigment cells. It does not change your natural skin colour.

Blemish-Prone Skin and Post-Acne Marks

Why This Combination Suits Blemish-Prone Skin

Three things work together here: the azelaic complex on inflammation and marks, betaine salicylate inside the pores, and zinc PCA on oil. That is a sensible trio for oily, breakout-prone skin.

Post-Acne Dark Marks

The flat brown or red marks left after a blemish clears are what this serum is best suited to. Expect two to three months of consistent use, with sunscreen every day.

Acne Scars Are Different

Indented or raised scars are structural changes and will not respond to any serum. Those need professional treatment.

It Is Not an Acne Medication

Anua reports non-comedogenic and low-irritation testing, and the formula is built for blemish-prone skin. But moderate or severe acne needs medical treatment, and this is not a substitute for it.

Neem, Green Tea and Centella

The botanical side of this formula deserves naming properly, because the ingredient list hides it behind Latin names.

Neem — Melia Azadirachta

The formula contains neem leaf extract (15th) and neem flower extract (18th). Neem needs no introduction in this part of the world — it has been used on skin here for generations, and it remains one of the most trusted traditional ingredients for blemish-prone skin.

Its presence in a Korean serum is unusual and worth knowing about. As with any botanical at this position, treat it as part of the formula’s character rather than its main active.

Green Tea Leaf Water — Camellia Sinensis, 16th

Used in place of some of the plain water, bringing green tea’s naturally occurring antioxidant compounds into the base of the formula.

The Centella Complex

This is the most thorough centella system we have seen in a serum at this price. It contains three separate centella extracts — leaf, root and whole plant — plus all four of its main active compounds listed individually: madecassoside, asiaticoside, asiatic acid and madecassic acid.

Most products list “Centella Asiatica Extract” and stop there. Naming the four compounds separately indicates a deliberately built complex rather than a single extract.

Aloe Vera — 20th

Aloe barbadensis leaf juice, adding to the soothing and hydrating side.

Hydration and Skin Comfort

The Hydrating Ingredients

Panthenol (6th), Glycerin (10th), Biosaccharide Gum-1 (11th) and Sodium Hyaluronate (17th). Biosaccharide Gum-1 is worth noting — it is a film-forming humectant chosen specifically for its comfort on sensitised skin.

The Barrier Ingredients

Squalane (29th), Hydrogenated Lecithin (34th) and Ceramide NP (35th — the final ingredient). These are present at cosmetic levels; the ceramide in particular is a very small inclusion, so read it as a formulation touch rather than a barrier-repair dose.

Does It Replace a Moisturizer?

No — and with two actives in the bottle, following with a moisturizer is not optional. A plain, fragrance-free moisturizer over the top is what keeps this serum comfortable in the first weeks.

The KPOP Demon Hunters Edition

This is a special collaboration release tied to the animated film, in distinctive green-and-black packaging with collaboration artwork.

The Gift

The packaging advertises a Gat Keyring as a gift with the edition. Confirm with the seller that the keyring is included in the package you are buying, as gift availability varies by batch and retailer.

Is the Formula Different?

It carries the same redness-soothing, azelaic complex positioning as the standard line. Ingredient declarations can differ between packaging versions, so check the label on the bottle you receive.

About the Size

This edition is 50ml. The standard Anua Azelaic Acid 10 Hyaluron serum is also sold in 10ml and 30ml, which are separate products rather than size variants of this collaboration edition. If you want the collaboration packaging, the 50ml is the one.

Key Ingredients and Their Benefits

Disodium Azelate — 2nd

The water-soluble salt of azelaic acid, and the formula’s principal azelaic ingredient. Covered in detail in its own section above.

Panthenol — 6th

Provitamin B5, placed unusually high. Supports hydration and skin comfort — a sensible choice in a formula carrying two actives.

Azelaic Acid — 7th

Free azelaic acid, the classic dermatological form, present in a supporting rather than leading position.

Betaine Salicylate — 9th

The formula’s second active, a BHA-type ingredient working inside the pores. See its dedicated section above.

Biosaccharide Gum-1 — 11th

A film-forming humectant chosen for its comfort on sensitised skin.

Allantoin and Dipotassium Glycyrrhizate — 13th and 14th

Two long-established soothing ingredients, both placed high for their type.

Neem Leaf and Flower Extract — 15th and 18th

Melia Azadirachta, in two forms. Covered in its own section above.

Sodium Hyaluronate — 17th

A hyaluronic acid derivative that binds water at the skin surface — the “Hyaluron” of the product name.

Niacinamide — 19th

Vitamin B3, supporting barrier function and the appearance of uneven tone. Its concentration is not disclosed.

The Centella Complex — 22nd to 28th

Three centella extracts plus its four main compounds, listed individually.

Zinc PCA — 30th

Used in formulas for oily and blemish-prone skin, supporting oil balance.

Squalane, Hydrogenated Lecithin and Ceramide NP

The barrier-supporting ingredients, at 29th, 34th and 35th. Ceramide NP is the last ingredient in the list — a small, cosmetic-level inclusion.

Which Skin Types Can Use This Serum?

• Blemish-Prone Skin: The clearest fit — azelaic complex, BHA and zinc PCA together.
• Post-Acne Marks: What the azelaic complex and niacinamide are best suited to.
• Oily Skin: Light texture, with zinc PCA and a BHA.
• Combination Skin: Comfortable across the face.
• Mild Redness from Dryness or Weather: The soothing system is genuinely well built.
• Uneven Skin Tone: Two ingredients working on pigment by different routes.
• Normal Skin: Usable for tone and texture maintenance.
• Dehydrated Skin: Hydrating, but follow with a moisturizer.
• Dry Skin: Usable with a proper moisturizer over it; the actives can be drying.
• Sensitive or Reactive Skin: Approach slowly. Two actives plus propylene glycol at third. Patch-test, start at one drop once a week.
• Persistent Facial Redness or Suspected Rosacea: See a doctor first.
• Pregnancy or Breastfeeding: Consult a healthcare professional — see the precautions below.

How to Use Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum

1. Patch-test on the inner forearm for several days first.
2. Cleanse with a gentle cleanser.
3. Apply toner if it is part of your routine.
4. Start with one or two drops only — this is the manufacturer’s own advice.
5. Spread gently across the face, avoiding the eyelids and lips.
6. Pat lightly until absorbed.
7. Always follow with a moisturizer.
8. Begin at once or twice a week if azelaic acid is new to you.
9. Increase frequency only when your skin stays comfortable for a few weeks.
10. Build up to a maximum of about five drops per application as needed.
11. Apply broad-spectrum SPF 30 or higher every morning.

Mild tingling on the first few applications is common with azelaic acid and usually settles. Burning, persistent stinging or increased redness means stop — that is too much, too soon.

More drops do not work faster. With two actives in one bottle, they mainly work more irritatingly.

Recommended Skincare Routine

Evening Routine

Step 1 – Cleanse: Remove makeup and sunscreen thoroughly.

Step 2 – Toner: Apply a hydrating toner if you use one.

Step 3 – Serum: One or two drops of this serum.

Step 4 – Moisturizer: A plain, fragrance-free moisturizer.

Morning Routine

Step 1 – Cleanse gently. Step 2 – Toner if desired. Step 3 – Serum, once tolerated. Step 4 – Moisturizer. Step 5 – Sunscreen, SPF 30 or higher.

Building Up Safely

Weeks 1 to 2: one application, one or two nights. Weeks 3 to 4: two nights. After that, increase slowly. Many people do well at three or four times a week and never need daily use.

Twice Daily

Anua permits morning and evening use once the skin tolerates it. It is not necessary for most people, and it is not where beginners should start.

Using It With Other Actives

With Other AHAs or BHAs

Be careful — this serum already contains a BHA. Adding another exfoliating acid is the most likely way to end up with dryness, stinging and more redness than you started with. Alternate nights at most.

With Retinol

Both can sit in one routine, but not on the same night while you are starting out. Alternate them, and introduce only one at a time.

With Vitamin C

Vitamin C in the morning, this serum at night, is the simplest approach.

With Niacinamide

Already present at 19th. A separate niacinamide product is fine but usually unnecessary.

With Hyaluronic Acid or Ceramide Moisturizers

Both pair very well — a hydrating serum underneath or a ceramide moisturizer over the top is exactly what makes an active serum comfortable.

With Benzoyl Peroxide or Prescription Acne Treatment

Ask your doctor first. If you are already on a prescribed treatment, adding a two-active serum on your own is not a good idea.

Important Usage Tips and Precautions

• For external cosmetic use only.
• Patch-test on the inner forearm for several days before first facial use.
• Start at one or two drops, once or twice a week, and build up slowly.
• Mild tingling on first use is common; burning or persistent stinging means stop.
• Avoid the eyelids, lips and mucous membranes.
• Do not apply to broken, sunburned or severely irritated skin.
• This serum contains two actives — an azelaic complex and a BHA. Be cautious about adding further acids or retinoids.
• Always follow with a moisturizer.
• Use broad-spectrum SPF 30 or higher every morning, particularly when treating pigmentation.
• If pregnant or breastfeeding, consult a healthcare professional before use. Topical azelaic acid is generally regarded as lower-risk, but this formula also contains betaine salicylate, a salicylate.
• Contains propylene glycol at third position — relevant if you know you react to it.
• Persistent facial redness, flushing or visible vessels may be rosacea and should be assessed by a doctor.
• Moderate or severe acne needs medical treatment; this is not a substitute.
• Non-comedogenic testing does not guarantee that every user stays breakout-free.
• It will not remove indented or raised acne scars, or change natural skin colour.
• Do not use more drops to get faster results.
• Store away from direct sunlight and excessive heat, and keep the bottle closed.
• Keep out of reach of children.

Frequently Asked Questions

1. Does this serum contain 10% azelaic acid?

Not 10% free azelaic acid, no. The formula’s main azelaic ingredient is Disodium Azelate, in second position — the water-soluble salt — with free Azelaic Acid only at seventh. The “10” refers to the combined azelaic complex. Anua does not publish a figure for free azelaic acid, and it cannot be worked out from an ingredient list.

2. Why use the salt instead of azelaic acid?

Free azelaic acid barely dissolves in water. That is why genuine high-strength azelaic products are thick creams. A light serum like this is only possible using the soluble salt.

3. Is it as effective as prescription azelaic acid?

It should not be presented as equivalent. The dermatological evidence for azelaic acid was built on free azelaic acid at 15–20%. If that is what you need, speak to a doctor. This serum is a gentler cosmetic product for skin that would not tolerate those strengths.

4. What else is in it besides azelaic?

A second active you should know about: Betaine Salicylate at ninth, a BHA-type ingredient. Plus a deep soothing system — panthenol at sixth, allantoin, dipotassium glycyrrhizate, beta-glucan, aloe, a seven-part centella complex, neem and green tea.

5. Does it really contain neem?

Yes — neem leaf extract at 15th and neem flower extract at 18th (listed as Melia Azadirachta). An unusual and welcome inclusion in a Korean serum.

6. Will it help my post-acne dark marks?

It is well suited to the flat marks left after blemishes clear. Expect two to three months of consistent use with daily sunscreen. Indented or raised scars will not change.

7. Will it cure my redness?

It targets the appearance of everyday redness from dryness and irritation. Persistent facial redness, flushing or visible vessels is often rosacea — a medical condition that needs a doctor, not a serum.

8. How should I start?

One or two drops, once or twice a week, following with a moisturizer. Build up slowly over several weeks. The manufacturer’s own maximum is about five drops. More drops will not work faster.

9. Can sensitive skin use it?

With real caution. Two actives plus propylene glycol at third position is more than the soothing name suggests. Patch-test for several days, start at one drop once a week, and stop if it burns rather than tingles.

10. Can I use it if I am pregnant?

Ask your doctor. Topical azelaic acid is generally considered lower-risk in pregnancy, but this formula also contains betaine salicylate, a salicylate — and that is the ingredient to raise with your healthcare professional.

11. Can I use it with other acids or retinol?

Carefully — this serum already contains a BHA. Adding another acid is the quickest way to dryness and more redness. Alternate nights at most, and never introduce two new actives at once.

12. What size and SKU is the KPOP Demon Hunters Edition?

The collaboration edition is 50ml, Product SKU 8800307378916, and advertises a Gat Keyring gift — confirm the contents with the seller. The standard 10ml and 30ml bottles are separate products, not size variants of this edition.
