Anua AZELAIC ACID 10 HYALURON REDNESS SOOTHING SERUM 30ML

Values You Can Trust: 100% Genuine | Fragrance-Free | FA-Safe | Pregnancy-Safe | Vegan-Friendly*

If your breakouts leave behind stubborn red or brown marks that take months to fade, this is not just an aesthetic frustration—it is prolonged vascular and pigmentary inflammation. Azelaic acid addresses both pathways simultaneously.

Brown or dark marks (PIH) are excess melanin. Red or pink marks (PIE) are damaged capillaries. If your marks are red/pink, a standard 'brightening' Vitamin C product alone will not fade them—you need the vascular-calming properties of Azelaic Acid.

Pros: Exceptionally gentle compared to AHAs/BHAs; targets both acne bacteria and pigmentation; highly hydrating base prevents typical acid dryness. Caveats: 10% concentration requires a 2-4 week adjustment period; can cause mild, transient tingling upon application during the first week.

*Self-assessed by Adilsons based on available INCI data. No animal-derived ingredients detected. This is NOT a formal vegan certification by The Vegan Society or equivalent body.

Safety Classification: YELLOW (Caution, 14+ with guidance).

While gentler than heavy exfoliating acids, 10% Azelaic Acid is a clinical-grade active that alters cellular turnover and reduces melanin synthesis. Prepubescent skin does not experience the hormonal sebum surges or complex pigmentation issues that this active is designed to treat.

If a younger teen is experiencing severe early-onset acne or diagnosed rosacea, this can be used under dermatological guidance. For simple tween hydration, choose the Dr.Althea 345 RELIEF CREAM instead.

This serum is highly bedside-table compatible. It requires no rinsing and dispenses cleanly via a dropper. If you are too exhausted for a full routine, applying this onto unwashed (but relatively clean) skin will still deliver active acne-fighting and soothing benefits.

Because it is formulated in a hydrating hyaluronic acid base, it can occasionally serve as a single-product PM routine for oily skin types during high-humidity nights when executive function is low.

Step 1: Use in the PM initially (can expand to AM/PM once adapted).

Step 2: Dispense 2-3 drops (a pea-sized puddle) into your palm.

Step 3: Pat gently onto completely DRY skin to minimize initial tingling.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

1. Water rinse or gentle cleanser.
2. Hydrating Toner (optional).
3. Anua Azelaic Acid 10 Hyaluron Serum (apply to dry skin).
4. Lightweight Moisturizer.
5. Sunscreen (SPF 50+).

In Mauritius morning humidity, humectants (HA, glycerin) work exceptionally well because they draw water from the humid air rather than from deeper skin layers. The hyaluronic acid in this formula plumps the skin while the azelaic acid controls daytime sebum.

SPF MANDATE: While azelaic acid does not increase sun sensitivity as dramatically as AHAs, treating hyperpigmentation without daily SPF 50+ renders the active completely useless. Sunscreen is non-negotiable.

1. Double Cleanse (Oil cleanser followed by water-based foam).
2. Soothing Toner (optional).
3. Anua Azelaic Acid 10 Hyaluron Serum (apply to dry skin).
4. Barrier Repair Cream (e.g., Dr. Althea 345 Relief Cream).

If you are utilizing a Skin Cycling routine, place this serum on your "Exfoliation/Active" night, or use it on recovery nights ONLY if your skin is fully acclimated to 10% azelaic acid.

Pat/Press (do not rub)—friction degrades formulas, increases micro-circulation, and exacerbates the redness you are trying to treat.

Apply to dry skin. Damp skin increases the penetration rate of water-soluble acids, which dramatically increases the risk of stinging and irritation.

Hands deliver 100% of product. Cotton pads absorb approximately 30-40%. Use hands to prevent wasting this active serum.

This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.

Do not layer retinoids with AHA/BHA in the same night; keep 'one lane' per night. One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration can always accompany. If unsure: default to the safest lane = barrier/hydration, and reduce layers.

Viscosity Ladder Position: Rung 3 (Light Fluid / Serum). Apply after water-thin toners, but before medium lotions and thick creams.

This is a water-phase serum. It must be applied before any emulsion or oil-phase product. Layering it over oils will physically block the Azelaic Acid from interacting with the stratum corneum.

Azelaic acid is a larger molecule (molecular weight 188.22 Da), which means it safely adheres to the 500 Dalton Rule and easily penetrates the epidermal barrier to target deeper sebaceous glands and melanocytes.

While azelaic acid is gentle, 10% is a clinical threshold. Take at least 2-3 required recovery days per week during your first month. This prevents cumulative trans-epidermal water loss (TEWL).

Overuse Warning: Maximum safe frequency is twice daily (AM and PM). Exceeding this does NOT produce faster results — it produces barrier damage and paradoxical inflammation.

Purging vs. Reaction: Azelaic acid can cause mild purging. PURGING: occurs in usual breakout areas, surface-level, resolves in 4-6 weeks. REACTION (stop immediately): occurs in NEW areas, burning/swelling/hives, worsens without improvement.

Before starting this product, your routine MUST already include: a gentle cleanser, a barrier-supporting moisturizer, and a dedicated SPF 50+. Without these foundations, this product causes more harm than benefit.

If your skin stings on moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking — your barrier is below threshold. Start with a barrier repair cream first.

For Fitzpatrick Types IV-VI (melanin-rich skin), Azelaic Acid is highly recommended. Unlike strong chemical peels or high-dose AHAs, it selectively targets hyperactive melanocytes (excess pigment) without bleaching normal skin, making it extremely safe against rebound hyperpigmentation.

Post-Inflammatory Erythema (PIE): Azelaic acid reduces the dilation of superficial capillaries and directly targets the inflammatory cascade that causes red, pink, or purple post-acne marks.

Post-Inflammatory Hyperpigmentation (PIH): Acts as a tyrosinase inhibitor, actively blocking the enzyme responsible for melanin overproduction in the skin.

Explicitly, this product cannot physically shrink pores. It keeps them clear of oxidized sebum (which makes them look smaller), but pore size is genetically determined. Cannot lighten your natural skin tone — 'brightening' means fading excess pigment, not changing your natural complexion.

1. Dr.Althea 345 RELIEF CREAM 50ML. The ceramides in this cream immediately rebuild the lipid matrix that active acids temporarily disturb. Use AM/PM after the serum.

2. Beauty of Joseon RELIEF SUN AQUA FRESH RICE + B5 50ML. Essential UV defense to prevent PIH from darkening while azelaic acid does its work. Use AM.

3. Anua HEARTLEAF QUERCETINOL PORE DEEP CLEANSING FOAM 150ML. Preps the skin by removing excess sebum without stripping, allowing the 10% azelaic acid to penetrate effectively. Use PM.

If you layer this serum with heavy silicone primers, it may pill. Mitigation: allow the serum to dry for a full 60 seconds, and gently pat (do not rub) subsequent layers.

This is a conflict-solver for ACTIVE ingredients. If you run multiple actives, use these rules to avoid irritation, deactivation, and barrier damage.

UNIVERSAL RULES:
One Active Lane per routine: In a single AM or PM routine, run only one primary "active lane" (Retinoid OR Acid Exfoliation OR L-Ascorbic Acid Vitamin C OR Benzoyl Peroxide OR Hydroquinone OR strong acne lane).
If you break a rule: Don't "push through." Reduce frequency, split AM/PM, or alternate nights.
Barrier override: If moisturizer stings or skin feels tight within 30 minutes of cleansing → pause all actives and run barrier-only for 3-7 days.
Wait-time defaults (practical): watery layers 10-20s, serums 30-60s, pH-dependent acids 10-20 min if you insist on layering (split is safer), sunscreen 10-15 min before sun.

A) Retinoid Lane Conflicts (Retinol / Retinal / Tretinoin / Adapalene)
Retinoids × AHAs (Glycolic / Lactic / Mandelic / PHA strong)
Rule: Never in the same night (irritation + barrier thinning risk).
Instead (best options): Skin Cycling (4-night): Night 1 AHA → Night 2 Retinoid → Nights 3-4 Recovery. Alternate Nights: AHA 1-2x/week, retinoid 2-4x/week (separate days). AM/PM split (only if tolerant): AHA in AM with strict SPF, retinoid PM.
Retinoids × BHA (Salicylic Acid 0.5-2%)
Rule: Avoid same night for most people (dryness + irritation synergy).
Instead: Alternate Nights: BHA on non-retinoid nights. AM BHA / PM Retinoid (safer than same layer). Low-dose exception: Very oily, resilient skin may tolerate — but treat as advanced.
Retinoids × Benzoyl Peroxide (BPO)
Rule: Do not layer (BPO can oxidize/deactivate retinol/tretinoin; plus double irritation).
Instead: AM BPO / PM Retinoid. Wash-off BPO cleanser in AM, retinoid PM (lower irritation). Exception: Adapalene is more stable; some fixed combos exist (still irritating → buffer + moisturizer).
Retinoids × L-Ascorbic Acid (pure Vitamin C)
Rule: Don't layer in same routine (irritation load + incompatible pH preferences).
Instead: AM Vitamin C / PM Retinoid (classic split).
Retinoids × Strong "Peel" Actives (high AHA %, strong exfoliating pads, peels)
Rule: Never same day; treat peels as their own lane.
Instead: Peel night → 48-72h recovery → then resume retinoid.

B) Vitamin C Lane Conflicts (L-Ascorbic Acid focus)
L-Ascorbic Acid × Benzoyl Peroxide
Rule: Never combine (oxidation → loss of Vitamin C activity).
Instead: Vitamin C AM, BPO PM (or alternate days).
L-Ascorbic Acid × Copper Peptides
Rule: Separate (copper ions can accelerate oxidation; low pH can destabilize peptides).
Instead: Vitamin C AM, copper peptides PM (or alternate days).
L-Ascorbic Acid × AHAs/BHAs (separate products)
Rule: Avoid layering (excess acidity → stinging + barrier irritation).
Instead: AM Vitamin C / PM Acids. If insisting: Vitamin C first, wait 15-20 min, then acid (still higher risk).
L-Ascorbic Acid × High-% Niacinamide (sensitive skin)
Rule: Generally compatible in modern formulas, but can trigger flushing in reactive skin.
Instead: Wait 10-15 min after Vitamin C before niacinamide. Or split: Vitamin C AM, niacinamide PM.

C) Exfoliation Lane Conflicts (AHA/BHA/PHA)
AHA × BHA (layering two separate strong products)
Rule: Avoid stacking separate strong exfoliants (over-exfoliation risk).
Instead: Use one combined formula (chemist-balanced) OR Alternate days: BHA for pores; AHA for texture.
Chemical Exfoliants × Physical Scrubs / Brushes / Microderm tools
Rule: Don't combine same day (micro-tears + "glazed donut" over-strip).
Instead: Choose chemical exfoliation OR gentle physical occasionally — never both together.
Direct Acids × Peptides (especially copper peptides)
Rule: Avoid immediate layering (low pH can destabilize peptide bonds).
Instead: Peptides AM, acids PM, or wait 20 min after acids.
Acids × Strong Retinoids (repeat of lane rule)
Rule: Not same night.
Instead: Skin cycling / alternating nights.

D) Oxidation / Deactivation Conflicts (chemistry problems)
Benzoyl Peroxide × Antioxidants (Vitamin C, some polyphenols)
Rule: Keep separate (BPO oxidizes).
Instead: Antioxidants AM, BPO PM (or wash-off BPO).
pH-dependent actives stacked together (too low pH "acid load")
Rule: Don't stack multiple low-pH products back-to-back unless advanced.
Instead: Split across routines or days.

E) Layering Physics Conflicts (penetration + pilling + "wasted product")
Oil-first × Water-based serums (physics barrier)
Rule: Don't apply facial oils before water serums.
Instead: Water → serum → moisturizer → oil (oil last).
Heavy silicones over damp/wet layers (pilling risk)
Rule: Don't rub silicone layers over wet serums.
Instead: Wait 60 seconds, then pat silicone product.
Too many film-formers stacked (pilling + patchy sunscreen)
Rule: Reduce layers before SPF; sunscreen needs even film.
Instead: Morning: fewer layers + longer dry time before SPF.

F) "Same Pathway" Redundancy Conflicts (not dangerous, just pointless)
Duplicate actives in the same lane (no added benefit, more irritation)
Rule: Don't stack two products that do the same job (e.g., two strong acids, two retinoids).
Instead: Pick one primary active; use the other on alternate nights or not at all.
Multiple strong brighteners at once (irritation > gains)
Rule: Don't stack LAA + strong acids + retinoid all together chasing "fast glow."
Instead: Choose one lane; add supportive pigment helpers (niacinamide/TXA) on non-irritating days.

Template A: AM/PM Split (most common)
AM: Antioxidant lane (Vitamin C) → Moisturizer → SPF
PM: Retinoid OR Acid lane → Moisturizer

Template B: 4-Night Skin Cycling
Night 1: Exfoliation lane
Night 2: Retinoid lane
Night 3-4: Recovery (no actives)

Template C: Alternate-Night Protocol (simpler)
Mon/Wed/Fri: Retinoid
Tue/Sat: Acid or BHA
Thu/Sun: Recovery

Pre-period breakouts happen because progesterone causes the pore lining to physically swell, narrowing the opening and trapping sebum beneath. Azelaic acid prevents the subsequent bacterial colonization and immediately calms the infundibular edema (swelling).

Chronic stress elevates cortisol, which breaks down collagen, increases TEWL (Transepidermal Water Loss), triggers inflammatory acne, and compromises barrier function.

When you are highly stressed, your skin shifts into a pro-inflammatory state. The 10% Azelaic Acid works as a direct anti-inflammatory agent, downregulating the cytokines triggered by cortisol spikes, stopping stress-induced breakouts before they surface.

Permeability: Water-Permeable (wudu-compatible).

This is a water-based, rapidly absorbing serum that leaves no occlusive or waterproof film on the skin. It absorbs completely into the epidermis, allowing water to reach the skin's surface without obstruction.

Adilsons provides this assessment based on the product's physical properties. Rulings on wudu validity vary between scholars. Consult your own trusted Islamic authority.

MYTH: 'Azelaic acid is a harsh chemical peel like Glycolic Acid.' REALITY: Azelaic acid is a naturally occurring dicarboxylic acid produced by yeast on normal skin. It regulates cell turnover without severing the desmosome bonds as aggressively as AHAs.

MYTH: 'If it burns, it means it is working.' REALITY: Mild tingling for 10-30 seconds is normal for 10% azelaic acid. Persistent burning means your barrier is broken and the acid is triggering an immune response.

In air-conditioned environments, hyaluronic acid draws moisture FROM your deeper skin layers instead of from the air. ALWAYS seal this product with an occlusive when in AC for extended periods.

July-November: PM2.5 increases during sugar cane harvest burns. This serum reduces the inflammatory response caused by micro-particulate pollution adhering to the skin.

The pH of this formulation is typically balanced around 4.5-5.5 to ensure the Azelaic Acid remains stable while minimizing irritation to the acid mantle.

*Ingredient order and exact composition may vary slightly by production batch; refer to physical packaging for absolute INCI.

Fragrance Status: Fragrance-Free.

Scent Description: Faint, characteristic acidic/medicinal scent inherent to pure azelaic acid. No masking fragrances are used.

Intensity and Dissipation: Intensity (1/5). Dissipation (Under 30s).

EU 26 Allergen Screen: None detected in declared INCI. Alcohol Disclosure: Free of drying alcohols (Ethanol/Denatured Alcohol).

Halal Status: *Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram animal-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars.

Vegan Status: *Self-assessed by Adilsons based on available INCI data. No animal-derived ingredients detected. This is NOT a formal vegan certification by The Vegan Society or equivalent body.

Cruelty-Free Status: *Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. *Brand states cruelty-free, but sells products in Mainland China where post-market animal testing may be required by law. Cross-border e-commerce sales may be exempt.

Microplastic-Free: Yes.

MFDS Classification: General Cosmetic. Contains actives well within cosmetic regulatory limits.

The Korean '미백' (mibaek) classification means regulation of melanin production — fading dark spots to reveal your natural tone. It does NOT bleach or change your natural complexion.

Evidence Confidence: High. Azelaic acid at 10% is globally recognized in dermatological literature for the treatment of mild-to-moderate rosacea and acne vulgaris.

Fungal Acne Safety: FA-Safe based on standard water-and-acid formulation without Malassezia-feeding lipid chains. Azelaic acid itself creates a hostile environment for yeast.

Pilling Assessment: Low.

Pilling generally only occurs if this serum is applied immediately over thick, heavy oils, or if silicone-heavy sunscreens are aggressively rubbed (rather than patted) over it before it has fully dried.

Mitigation: Apply to completely dry skin, wait 60 seconds for the hyaluronic acid to bind, and pat subsequent layers gently.

Fresh Color: Clear to slightly cloudy. Azelaic acid is highly stable and does not oxidize rapidly like pure L-Ascorbic Acid (Vitamin C).

In extreme cold, azelaic acid formulations can sometimes exhibit minor crystallization. This is harmless. Store at room temperature in Mauritius, away from direct sunlight.

Spoilage Signs: Distinct change in smell (sour/rancid) or complete, irreversible separation. When in doubt, discard.

Patch Test: Apply a small drop to the inner forearm for 24h. If clear, apply behind the ear for 24h. If clear, proceed to facial use.

If adverse reaction: STOP ALL ACTIVES. For 72 hours, use ONLY gentle cleanser + plain moisturizer + mineral SPF. NO acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72h, reintroduce ONE product per 14 days.

Emergency Stop Signals: Hives, swelling, blistering, persistent burning, breathing difficulty (seek emergency care).

1. Applying to damp skin: Water pulls the acid into the skin too quickly, causing intense stinging.

2. Using with AHAs/BHAs: Stacking multiple acids in one routine destroys the acid mantle.

3. Skipping moisturizer: Azelaic acid controls sebum; without moisturizer, the skin may overcompensate by producing more oil.

4. Spot-treating only: Azelaic acid prevents future breakouts and regulates overall skin tone—it is best used on the entire face, not just on active pimples.

Maximum safe continuous use is twice daily. Exceeding this strips the stratum corneum.

Volume: 30ml. Recommended amount per use: 0.5ml (2-3 drops). Uses per container: approximately 60 applications.

At recommended dosage (once daily): approximately 60 days (2 months). At common overdosing (2-3x recommended): depletes in approximately 24 days. Correct dosage is better for your skin AND extends product life.

Reorder in approximately 1.5 months. We recommend reordering 2 weeks before estimated depletion for shipping time.

Azelaic acid requires robust barrier support and strict UV protection to yield results.

The Anua Azelaic Acid 10 Serum acts as your primary active treatment step (Viscosity Rung 3), aggressively targeting vascular redness and excess pigment while the rest of your routine buffers and protects.

AM Routine:
1. Water rinse.
2. Optional Toner.
3. Anua Azelaic Acid 10 Serum (2-3 drops, fully dry skin).
4. Dr.Althea 345 RELIEF CREAM (1-2 peas).
5. Beauty of Joseon RELIEF SUN AQUA FRESH (2-finger rule).

PM Routine:
1. SKIN1004 MADAGASCAR CENTELLA LIGHT CLEANSING OIL.
2. Anua HEARTLEAF QUERCETINOL PORE FOAM.
3. Optional Toner.
4. Anua Azelaic Acid 10 Serum (2-3 drops, fully dry skin).
5. Dr.Althea 345 RELIEF CREAM.

Wait times: Wait 30-60s after applying the serum before moving to moisturizer. Sunscreen before makeup/sweat: 10-15 min.

If you are in the luteal phase (pre-period breakouts), then increase use to AM and PM to intercept infundibular swelling.

If your skin feels tight or stings upon application, then apply your Dr. Althea moisturizer FIRST, wait 2 minutes, and apply the Azelaic acid on top (buffering).

After purchasing, you will receive our skincare education email series covering this product in depth.

The recommendations above are based on formulation synergy with Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.

This product's PRIMARY function is: Inflammation reduction, redness calming, and PIE/PIH fading. You do NOT need this if you already own: A dedicated 10% Azelaic Acid prescription or another strong acne/redness active that currently controls your symptoms. Finish your current product before purchasing.

Check your current shelf. Do you have an open product with the same primary active? Skincare products lose efficacy after opening (PAO = 12 months). Buying new while old expires is waste.

Combining with a similar product: No Benefit (same mechanism) / Marginal Benefit (overlapping).

This product is sourced through authorized Korean distributors — primarily Craver Co., Ltd (South Korea), alongside other verified distribution partners. Craver is a major Korean beauty distributor and the parent company of SKIN1004, handling authorized distribution for multiple K-beauty brands.

Look for the crisp Anua typography and verify the lot numbers stamped cleanly on the base of the bottle.

Brand: Anua. Founded in South Korea. Philosophy: Keep things simple, natural, and soothing.

Anua approaches formulation through the lens of subtraction. Instead of overloading products with complex synthetic active cascades, they isolate highly effective, time-tested soothing ingredients (like Heartleaf and Azelaic Acid) and formulate them at clinically meaningful concentrations. Their focus is consistently on reducing skin stress.

Common Praise: Users on r/AsianBeauty with rosacea consistently note that this serum visibly drops baseline redness within the first two weeks of use. Oily skin types praise the weightless, non-greasy finish compared to traditional prescription azelaic acid creams.

Common Complaints: Some users with very dry skin report that it doesn't offer enough standalone hydration despite the hyaluronic acid, necessitating a robust cream on top. A few mention the characteristic slight tingle during the first few days of use.

Please recycle the glass bottle locally once emptied and rinsed.

Can I use this with Vitamin C?

It is best to separate them. Use Vitamin C in the AM and this Azelaic Acid serum in the PM to avoid overloading your skin barrier with too many active pathways at once.

Will it make my skin peel?

No. While azelaic acid gently regulates cell turnover, a 10% formulation in a hyaluronic acid base is not a peeling agent and will not cause visible shedding of the skin.

Can I use it on active breakouts?

Yes. Azelaic acid has potent antimicrobial properties that specifically target the bacteria responsible for acne, making it excellent for active blemishes.

Does it have the gritty texture of prescription azelaic acid?

No. This cosmetic formulation is a smooth, elegant liquid serum, completely avoiding the gritty or paste-like texture often found in high-dose prescription azelaic creams.

Best For: Oily, acne-prone, and sensitive skin types struggling with persistent redness, active breakouts, and post-acne marks (PIE and PIH).

Key Benefits: Clinically proven 10% Azelaic Acid directly neutralizes inflammation and targets hyperpigmentation. Hyaluronic acid base prevents the dryness associated with prescription treatments. Highly elegant, rapid-absorbing texture suited for high humidity.

Keep in Mind: It is an active ingredient and requires adjustment; transient tingling is common initially. Must be supported by a solid barrier cream and dedicated sunscreen use.

• Week 1-2: Introduce this product alone at low frequency (details in table below). Monitor for stinging, redness, or breakouts.
• Week 3-4: If stable, increase frequency per table below.
• Week 5+: Add one support product only if needed.
• If irritation at any point: 72-hour barrier reset (see Section 33B).

This product must be introduced as the ONLY new product. Wait 14 days before adding anything else.

In air-conditioned environments, the significant Hyaluronic Acid content in this formula experiences vapor pressure deficit, drawing moisture FROM your deeper skin layers instead of the air. ALWAYS seal this serum with an occlusive moisturizer if you work in an AC office for 8+ hours.

If you experience thermal shock flushing (sudden facial redness when transitioning from hot outdoors to AC), the anti-inflammatory properties of the azelaic acid help rapidly downregulate this vascular response.

End of Week 2: Any persistent redness or burning? YES → stay at Week 1-2 frequency for 2 more weeks. NO → proceed to Week 3.
