Hyaluronic acid
A four-week trial on the legs of 36 older adults found higher hydration with a low-molecular-weight HA lotion than a high-molecular-weight lotion or the base. Water loss and symptom scores did not differ significantly.

Azelaic acid
The cited 2025 review reports that 15–20% prescription-strength azelaic acid products improved acne and rosacea measures in the trials it assessed. It says results depend on the vehicle, or product base. The review does not establish the effects or tolerability of the cosmetic serums listed here.

Official directions and routine order
Official directions
Apply 1-2 times a week and gradually increase the frequency to up to twice a day. Use 1-2 drops per use to begin, up to 5 drops can be used. Apply an adequate amount in between a toner and moisturizer. If used during the day, be sure to pair it with SPF 30 or higher.
Official directions checked 2026-10-24 ↗Start 1–2 times a week per the label, increasing gradually. Non-comedogenic is the brand's description.
TWO US FORMULAS / TWO STARTING POINTS
Anua azelaic acid or niacinamide/TXA serum: what is different?
Start with the concern you want to address. Anua positions the azelaic serum for visible redness and blemish care, and the niacinamide/TXA serum for dark spots and uneven-looking tone. Those purposes overlap; they do not establish which product will work better for you.
Swipe across the table to read both products. With a keyboard, focus the table and use the arrow keys.
| What changes | Azelaic Acid 10 Hyaluron Redness Soothing Serum → | Niacinamide 10 TXA 4 Serum → |
|---|---|---|
| Disclosed actives | 10% azelaic acid | 10% niacinamide · 4% tranexamic acid · 2% arbutin |
| Brand's stated focus | The look of redness and blemish-related marks | The look of dark spots, dullness and uneven tone |
| Official starting directions | Begin with 1–2 drops, 1–2 times a week. Increase gradually, up to twice daily, as directed. | A few drops on the areas you want to address, morning and night. |
| Routine position | Between toner and moisturizer; SPF 30+ in daytime | Before moisturizer; SPF 30+ in daytime |
| Source | Anua US azelaic serum · ingredients and directions ↗ | Anua US niacinamide/TXA serum · ingredients and directions ↗ |
The azelaic serum also lists niacinamide and betaine salicylate. Anua does not state their percentages on that product page, so the two bottles are not simply “azelaic acid versus niacinamide.”
The linked pages do not report a direct comparison of these two formulas. The percentages are label information, not a potency score or a reason to combine the products. Follow the directions on the version you buy.
Open these two serums in the ingredient comparison →What is in the 10% azelaic acid formula?
Anua states 10% azelaic acid. The ingredient list also includes betaine salicylate; its concentration is not published. These are separate ingredients, so the 10% figure should not be read as the amount of betaine salicylate.
Panthenol, allantoin, sodium hyaluronate, squalane and ceramide NP are also listed. Their presence helps describe the formula, but does not establish the result of the finished serum on an individual person.
| Step | Published direction |
|---|---|
| Amount and frequency | Start with 1–2 drops, once or twice weekly. The page allows up to 5 drops and gradual frequency increases up to twice daily. |
| Routine order | Between toner and moisturizer. |
| Daytime | Pair with SPF 30 or higher. |
FIT GUIDE
Does it fit your skin — and your routine?
Written from the official US product information checked 2026-10-20. Brand claims are labelled as brand claims, and ingredient research is never presented as a test of this product.
THE SHORT ANSWER
What it is for
A leave-on treatment serum with a disclosed 10% azelaic acid, aimed by the brand at the look of post-blemish marks, uneven texture and excess oil, with a soothing complex built around it. Follow the directions for this azelaic-acid serum rather than treating all three products as interchangeable.
Consider it if
You get lingering marks after blemishes, your skin feels oily with visible congestion, and you want one measured active step rather than several. The label publishes a gradual ramp-up schedule, which suits first-time azelaic users.
Probably skip it if
Your main goal is simple soothing or hydration — the centella serums in the comparison table do that without an exfoliating ingredient. Also skip stacking it on top of another leave-on exfoliant until you know how your skin handles this one.
What it can replace
Part of a separate exfoliant’s job: the formula also contains betaine salicylate, a salicylic-acid derivative. It does not replace moisturizer or sunscreen, and it is not a prescription acne or rosacea treatment.
When to use it
Between toner and moisturizer. The official directions start at 1–2 times a week and build to twice a day. Many people keep active serums to the evening while they ramp up; if you use it in the morning, SPF 30 or higher is part of the official directions.
BY SKIN TYPE
Oily skin
The brand’s core audience for this serum: it describes oil control and a non-greasy, weightless finish. The ramp-up schedule still applies — oily skin is not automatically tolerant skin.
Acne-prone skin
Positioned by the brand for blemish-prone skin and described as non-comedogenic. Read that as a cosmetic for the look of post-blemish marks and texture, not as an acne medicine. Ongoing, painful or scarring acne is a dermatologist conversation.
Combination skin
Workable all over in a thin layer, or concentrated on the oilier T-zone and areas with marks. Drier cheeks may prefer fewer days per week.
Dry skin
Use with more caution. Azelaic acid plus betaine salicylate can feel drying, and the formula is lightweight rather than cushioning. Buffering it between a hydrating toner and a richer moisturizer, and staying at the low end of the frequency schedule, are sensible adjustments — routine advice, not brand directions.
Sensitive skin
Anua markets this serum to sensitive skin and publishes a slow ramp-up, which is a good sign of intent — but it is still an active serum with an exfoliating derivative in it. Tingling is commonly reported with azelaic acid products. Patch test, start at the label minimum, and stop if burning or a rash develops. Persistent facial redness can have medical causes; a cosmetic cannot diagnose or treat rosacea.
INSIDE THE FORMULA
Azelaic acid is second in the official US ingredient list, and the 10% figure is disclosed in the product name — a stronger basis for judging the formula than an ingredient that is merely present. For context from ingredient research: many clinical studies of azelaic acid use 15–20% prescription preparations. A 10% cosmetic serum is a different product category, so study results at prescription strength do not transfer directly.
The ingredient most likely to surprise people is betaine salicylate, a salicylic-acid derivative used for exfoliation support. It means this serum is not exfoliant-free: if your routine already includes a BHA or AHA leave-on, count this as part of that load rather than adding it on top without thinking.
Around the active sits a set of ingredients commonly used in soothing formulas: panthenol, allantoin, dipotassium glycyrrhizate (licorice), aloe leaf juice, beta-glucan, a centella complex with madecassoside, plus niacinamide, zinc PCA, squalane and ceramide NP near the end of the list. Their amounts are not disclosed; their presence explains the formula’s design, not a measured calming effect.
The brand describes the serum as non-comedogenic and low-irritation and reports testing badges on its page. Those are the brand’s own descriptions and tests of this finished product, which is the right level of evidence to ask for — and different from the ingredient-level azelaic research summarised on the azelaic acid ingredient page.
Worth checking in the list:
- Betaine salicylate: an exfoliating ingredient hiding in a “soothing” serum name. Check your total exfoliation load before combining with other acid products.
- Azelaic acid itself can tingle or itch at first. Tingling that escalates to burning, swelling or a rash is a stop signal.
- No added fragrance appears in the official US ingredient list, but several botanical extracts (melia, green tea water, centella, aloe) are present if plant extracts are a known trigger for you.
DO YOU NEED IT?
You already use a BHA or AHA leave-on
Do not simply stack them. This serum already contains betaine salicylate. Many people alternate days or keep one exfoliating step; running both daily is how routines quietly become too much.
You own a plain soothing serum (centella, heartleaf)
Different job. The soothing serum calms and hydrates; this one adds an active for marks and texture. If your skin is calm and marks are not your concern, you may not need this at all.
You are building a full “blemish routine” at once
New cleanser, new acid serum, new spot product in the same week is the classic way to irritate skin and learn nothing. Add this serum alone, at the label’s starting frequency, and hold everything else steady.
A simpler routine may suit you better
Start with the concern you want to address. If you are comfortable with your current routine and are not looking for an azelaic-acid step, there is no need to add this serum simply because it is popular. Persistent, painful or scarring breakouts call for medical advice rather than choosing a cosmetic by its ingredient percentage.
IN A REAL ROUTINE
The official directions give the schedule: apply 1–2 times a week and gradually increase to up to twice a day; start with 1–2 drops per use (up to 5 drops); apply between toner and moisturizer; pair with SPF 30 or higher in the daytime. The example below is editorial routine guidance around those directions.
Morning routine example
- Cleanse, or rinse with water
- Toner, if you use one (optional)
- This serum — only once your skin has completed the ramp-up; many people keep it to evenings at first
- Moisturizer
- Sunscreen, SPF 30 or higher
Evening routine example
- Cleanse
- Toner, if you use one (optional)
- This serum — a thin layer over the areas you are treating, or the whole face per the label amount
- Moisturizer
- Follow the label’s ramp-up literally for the first two weeks: 1–2 times a week is the starting point, not a suggestion for other people.
- The overlapping step is any other leave-on exfoliant (BHA, AHA, strong retinoid nights). Alternate days rather than layering until you know your tolerance.
- If your skin feels tight or starts flaking, the adjustment order is: fewer days per week, then a richer moisturizer over it, then a break. Do not answer irritation by adding more products.
- Under makeup, let the serum dry down fully before moisturizer and sunscreen. If pilling happens, try less product and allow more time between layers.
WHAT TO EXPECT
Brand descriptions and the published use schedule
- The brand positions this serum for the appearance of post-blemish marks. Azelaic-acid research provides ingredient-level context; the cited studies did not test this 10% cosmetic serum or establish when an individual mark may change
- Smoother-feeling texture and a less oily finish during the day, per the brand’s description
- A measured introduction to azelaic acid, thanks to the published ramp-up schedule
What the product information does not establish
- Prescription-strength results — the widely studied 15–20% preparations are medicines; this is a 10% cosmetic
- Treatment of acne or rosacea as diseases — cosmetics address appearance, and persistent redness or breakouts deserve a clinician
- An overnight change — neither the brand nor the ingredient research promises a date, and this page will not invent one
If a mark is changing shape, growing, or not healing, that is a medical question, not a skincare one — have it looked at.
SIDE BY SIDE
Three serum-step options for skin that flushes easily or marks after blemishes. Only the Anua contains azelaic acid; the other two are soothing serums without an exfoliating active — the first choice is whether your skin needs an active at all.
| Field | Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum (this product) | SKIN1004 Madagascar Centella Ampoule | Purito Wonder Releaf Centella Serum Unscented |
|---|---|---|---|
| Main job | Active care for the look of post-blemish marks, texture and oil, with soothing support | Simple soothing and light hydration with a short ingredient list | Soothing serum that pairs centella with niacinamide, panthenol and peptides |
| Key ingredients (brand listings) | Azelaic acid 10% (disclosed), betaine salicylate, panthenol, centella complex, hyaluronic acid | Centella asiatica extract, glycerin, butylene glycol | Centella asiatica extract, niacinamide, panthenol, peptides |
| Texture & finish | Lightweight, non-greasy (brand description) | Fluid, easy to spread, non-sticky finish (brand description) | Serum used before moisturizer; unscented version |
| Routine step | Treatment serum, between toner and moisturizer | Ampoule/serum step | Serum, before moisturizer |
| Size | 30 mL | 55 mL | 60 mL |
| Fits when | Marks and texture are the actual concern, and you will follow a ramp-up | Your skin wants the fewest moving parts and no exfoliating ingredient | You want centella plus a broader supporting cast, in an unscented formula |
| Easy to skip when | Your skin is calm and marks are not a concern | You specifically need an active for lingering marks | You prefer a single-focus centella formula |
Ingredient and texture lines follow each brand’s official listing. “Non-comedogenic” and “low irritation” are Anua’s descriptions of its own product.
BEFORE YOU BUY
- Check the exact name and size: “Azelaic Acid 10 Hyaluron Redness Soothing Serum”, 30 mL, on the Anua US store. Anua sells several similarly named serums (niacinamide, PDRN, rice ceramide) — the active differs.
- The full US ingredient list and the ramp-up directions were checked on the Anua US official page on 2026-10-20. Formulas and directions can change; the label on your bottle wins.
- Note the betaine salicylate in the list before combining this with other exfoliating products you own.
- Confirm current price, stock and delivery on the seller’s page; nothing on this page fixes them.
QUESTIONS
I have sensitive skin. How do I start?
Follow the official schedule: 1–2 times a week at first, 1–2 drops per use, increasing gradually toward twice a day only as your skin allows. Patch test first. Azelaic acid commonly tingles; burning, swelling or a rash means stop. The brand describes the serum as low-irritation and suitable for sensitive skin, but it contains an active plus betaine salicylate, so your own ramp-up matters more than the marketing.
Anua US official product page — How to use ↗Morning or evening?
The official directions allow up to twice a day once you have ramped up, with SPF 30 or higher if it is used in the daytime. Many people keep it to the evening while starting, simply because one new active is easier to judge there. Either way, sunscreen is the fixed last step of a morning routine.
Do I need a toner or essence as well?
No. The label places this serum between toner and moisturizer, but the toner is optional context, not a requirement. If your routine already has a hydrating essence, keep it only if it earns its place — this serum does not need a watery layer underneath to work as directed.
Can I use it with vitamin C, a retinoid, or my BHA toner?
Check the total load rather than looking for permission for one pair. This serum itself contains betaine salicylate, so a BHA toner on the same night is a second exfoliating step. A cautious pattern is to alternate evenings between exfoliating products and keep strong retinoid nights separate until you know your tolerance. Anua publishes no specific pairing prohibitions for this serum; if irritation appears, follow the product’s irritation warnings rather than adding more products.
Can I wear it under makeup?
Yes, once it has dried down — the brand describes a lightweight, non-greasy finish. Apply the serum, let it settle, then moisturizer and sunscreen. If foundation pills, try using less product and allowing more time between layers.
How long before post-blemish marks fade?
No honest date exists. Ingredient research on azelaic acid measures outcomes over weeks to months, and the brand gives no timeline for this serum. Judge it over a full ramp-up plus several consistent weeks, while following sunscreen directions — unprotected sun exposure works against fading marks.
Can I use it during pregnancy or while breastfeeding?
Marieclat does not make that call. Anua’s US page for this serum does not publish pregnancy or breastfeeding guidance, and the answer depends on your situation, not on a product page. Check the current label and ask your clinician or pharmacist before using any leave-on active in pregnancy or while breastfeeding.
