Skin1004 Madagascar Centella Niacinamide 10 Boosting Shot Ampoule 9ml

Values You Can Trust: 100% Genuine (Adilsons policy) / Cruelty-Free (PETA-listed)* / FA-Safe / Fragrance-Free / Halal-Friendly* / Pregnancy-Compatible (based on disclosed actives)*.

*SKIN1004's parent company Craver Co., Ltd is listed on PETA's own published "Beauty Without Bunnies" cruelty-free database — a real third-party certification, not a self-assessment — though the brand also sells through Tmall in mainland China, where post-market animal testing can legally apply; cross-border e-commerce sales may be exempt. Pregnancy compatibility reflects that none of the 21 declared ingredients (niacinamide, tranexamic acid, centella, etc.) are on standard pregnancy-contraindicated lists; it is not a substitute for your own doctor's advice.

*Treat the MFDS line as ingredient-class context, not a confirmed per-SKU registration number.

If breakouts keep leaving marks behind that outlast the breakout itself, that lingering discoloration — not the original pimple — is often what actually erodes confidence in the mirror. This ampoule is built to shorten that "afterglow" of a breakout, not to prevent the breakout itself.

PIH vs PIE: Brown or tan marks (PIH) are excess melanin and respond to niacinamide and tranexamic acid over weeks; red or pink marks (PIE) are damaged capillaries and respond more to centella and time. This product's niacinamide and tranexamic acid primarily target PIH; centella offers calming support for PIE-prone redness but this is not a dedicated PIE treatment.

Pros: Full ingredient list independently confirmed with three named, evidenced actives; spicule delivery system with a published (brand-commissioned) absorption claim; lightweight, fast-absorbing texture suited to humid climates; small trial size to test tolerance before a 30ml bottle.

Caveats: The spicule texture causes a brief tingling sensation some users find more noticeable than a standard serum; no independently peer-reviewed clinical study exists for this exact SKU, only brand-commissioned testing; the 9ml size runs out in a few weeks at daily use.

Classification: YELLOW (14+ with guidance). A 10% niacinamide concentration combined with an active spicule-delivery system is a genuine treatment-strength product, not a basic hydrator, so it sits above the "safe for all ages, no guidance needed" bar.

For a teen (14+) with oily or breakout-prone skin, starting at once daily for the first week and watching for tingling that lasts beyond a minute or two is the sensible approach rather than jumping straight to twice daily. Packaging is a simple dropper-bottle format with no youth-targeted branding, so there is no packaging-trap concern here.

This product is bedside-compatible: no sink, no rinsing, no precise dosage tool beyond counting drops, and it can be applied with unwashed hands in a pinch on a genuinely low-energy night. It requires a short 30-60 second wait before the next layer, which is short enough to qualify for a bare-bones routine.

It can anchor a minimum-viable 2-3 product routine (cleanser optional, this ampoule, moisturizer or SPF) when executive function is low. Its watery texture has no tacky drag or strong scent that would discourage use when you're exhausted, though the initial spicule tingle is worth expecting even on a tired night.

Step 1 (When): Morning, evening, or both, once your skin has adjusted.

Step 2 (How much): 2-3 drops for the full face and neck.

Step 3 (How): Smooth over clean, slightly damp skin, then pat gently until absorbed — do not rub, and expect a brief tingling sensation from the spicule texture.

The One Rule: 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) Gentle cleanser (optional if skin isn't oily overnight) → 2) Hydrating toner (optional) → 3) Skin1004 Madagascar Centella Niacinamide 10 Boosting Shot Ampoule, 2-3 drops → 4) Lightweight moisturizer if skin feels tight → 5) Sunscreen SPF30+ PA++++.

In Mauritius's humid mornings, this watery ampoule layers well because Butylene Glycol and Propanediol (both humectants confirmed in its ingredient list) pull moisture from the surrounding humid air rather than fighting it, so a heavy moisturizer often isn't needed underneath sunscreen.

1) Double cleanse if wearing sunscreen/makeup (oil cleanser then water-based cleanser); single cleanse otherwise → 2) Toner (optional) → 3) Skin1004 Madagascar Centella Niacinamide 10 Boosting Shot Ampoule, 2-3 drops → 4) Moisturizer to seal.

Because niacinamide and tranexamic acid are not photosensitizing, there's no circadian-specific reason this must be PM-only — this evening slot is simply where most people find room for an extra treatment step once the day's oil and sunscreen are cleansed off.

Technique: Pat/press into skin rather than rubbing — friction increases irritation and can degrade some active ingredients, and rubbing spicule textures specifically can feel more abrasive than patting. Apply to slightly damp skin so the watery texture spreads evenly instead of beading.

Wait time: 30-60 seconds before the next layer, since this is a serum-weight product, not a quick-absorbing toner.

Hands vs cotton pad: Hands deliver 100% of the product; cotton pads absorb approximately 30-40% of it. Use hands for this product — a cotton pad would also blunt the spicule delivery mechanism.

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.

Global execution rules: Viscosity ladder runs thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults: watery layers 10-20s, serum layers 30-60s, before sunscreen 10-15 minutes if heading outdoors. Amount defaults: watery toner/essence 5-8 drops, serum/ampoule 2-3 drops or 1 pump, eye product ½ rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, occlusive seal rice-grain to pea-size, sunscreen the two-finger rule for the face plus one finger for the neck. Hydrators go on slightly damp skin; retinoids go on fully dry skin; if the routine pills, stings, or feels heavy, reduce layers rather than adding more.

AM Maximum Stack: 1) Rinse/gentle cleanse (optional) → 2) pH-prep toner (optional) → 3) Hydrating toner layers (optional, 1-3) → 4) Essence (optional) → 5) Mist (optional) → 6) Booster/soothing serum (optional) → 7) Antioxidant lane, pick one (optional) → 8) Pigment-support lane, pick one — this ampoule fits here → 9) Hydration serum lane (optional) → 10) Oil-control/sebum-regulating lane, pick one (this ampoule could also sit here instead of the pigment lane, but not both) → 11) Peptide/repair lane (optional) → 12) Eye product (optional) → 13) Moisturizer → 14) Optional sealing layer (only if dry/AC) → 15) Sunscreen SPF50+ PA++++ (non-negotiable) → 16) Lip SPF (optional).

In AM, prioritize comfort and SPF adherence over stacking. In high humidity, fewer layers often perform better.

PM Maximum Stack: 1) Micellar pre-cleanse (optional) → 2) Oil cleanser/balm (if SPF/makeup worn) → 3) Water cleanser → 4) pH-prep toner (optional) → 5) Hydrating toner layers (optional) → 6) Essence (optional) → 7) Soothing/barrier serum (optional) → 8) [Anchor Product: this ampoule], 2-3 drops, wait 30-60 seconds → 9) Targeted serum (optional, only if non-conflicting) → 10) Moisturizer → 11) Sleeping mask (optional) → 12) Occlusive seal (optional; avoid if clog-prone) → 13) Spot treatment/pimple patch (as needed) → 14) Lip sleeping mask (optional).

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.

Tier: Light fluid/water-thin ampoule. Apply after thinner toners/essences and before thicker creams or oils.

Layering rule: Thinnest to thickest, water-phase before oil-phase. This product sits in the mid-routine "treatment" position, after hydrating prep steps and before the moisturizer that seals everything in.

Phase compatibility: Water-phase gel-fluid (Carbomer/Xanthan Gum-thickened); layers cleanly under an emulsion moisturizer or an oil-phase product without special sequencing beyond the standard thin-to-thick order.

Rest days: Niacinamide and tranexamic acid at these concentrations are generally well tolerated daily alongside centella, so no mandatory rest day is built in — but if tingling, redness, or tightness persists beyond the first week, drop to every other night.

Overuse warning: Applying more than the recommended 2-3 drops or layering it twice in one sitting does not speed up results — it increases the odds of tingling and pilling without adding benefit.

Purging vs Reaction: PURGING shows up in your usual breakout zones, stays surface-level, and resolves within 4-6 weeks — third-party review discussion threads we found do mention occasional breakouts on introduction, consistent with purging. A REACTION appears in new areas, involves burning, swelling, or hives, and worsens rather than improves — stop immediately if you see this pattern.

Prerequisites: Before starting this product, your routine should already include a basic cleanser and a daily moisturizer. Without a baseline moisture routine, a sebum-regulating active layered with spicules can leave oily-dehydrated skin feeling tighter, not better.

Barrier index gate: If your skin stings on moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking, your barrier is below threshold — start with the plain SKIN1004 Madagascar Centella Ampoule 55ml (pure centella, no niacinamide, no spicules) first and reintroduce this product once comfort returns.

Deeper skin tones (Fitzpatrick IV-VI): Because darker skin tones are statistically more prone to developing PIH after any inflammation, the spicule tingling and any breakout-purging phase in the first few weeks are worth monitoring closely — stopping at the first sign of a new dark mark forming is more protective than pushing through.

Excess sebum: Niacinamide is documented to help regulate sebaceous gland activity over consistent use, reducing surface shine without stripping the skin.

Post-inflammatory hyperpigmentation (PIH): Niacinamide inhibits the transfer of melanosomes from melanocytes to keratinocytes, and Tranexamic Acid interrupts the plasmin pathway that triggers excess melanin production after inflammation — the two actives target overlapping but distinct steps of the same pigmentation cascade.

Enlarged-looking pores: Oil-control from niacinamide combined with the spicule delivery system's absorption effect is the brand's stated mechanism for reduced pore appearance, reported in brand-commissioned testing after 4 weeks.

Secondary benefit: Centella Asiatica extract and Ascorbyl Glucoside (a stable Vitamin C derivative) add calming and antioxidant support respectively.

What this product cannot do: It cannot physically shrink pore size (pores don't have muscles to contract) — it can only reduce the appearance of pores by controlling the oil that makes them look larger. It also cannot lighten your natural skin tone; brightening here means fading excess pigment from marks, not altering your baseline complexion.

Every recommendation below was checked against Adilsons' live catalog before being included — no invented handles.

• SKIN1004 Madagascar Centella Ampoule Foam 125ml — a gentle centella-based cleansing foam that won't strip the skin before this ampoule goes on. AM or PM.
• SKIN1004 Madagascar Centella Toning Toner 30ml — preps and softens skin so the ampoule spreads evenly rather than beading over the spicule texture. AM or PM, before the ampoule.
• SKIN1004 Madagascar Centella Hyalu-Cica Moisture Cream 75ml — adds the hyaluronic acid this ampoule doesn't contain, sealing in hydration. Best PM, after the ampoule.
• SKIN1004 Madagascar Centella Air-Fit Suncream Light 50ml — a mineral SPF30 PA++++ sunscreen from the same range; brightening results from niacinamide and tranexamic acid only hold if pigment isn't being re-triggered by UV daily. AM, last step.

Pilling pairs: This ampoule can pill if applied over a thick, still-wet occlusive layer. Wait the full 30-60 seconds and use hands, not a cotton pad, to reduce that risk.

Pre-period breakouts happen because progesterone causes the pore lining to physically swell, narrowing the opening and trapping sebum beneath — a sebum-regulating step like this one, used consistently rather than started reactively, does more for that pattern than a rescue application after the fact.

Chronic stress elevates cortisol, which breaks down collagen, increases transepidermal water loss, and can trigger inflammatory breakouts and barrier weakness. Centella Asiatica is a well-documented calming botanical that supports the skin's response to that kind of inflammatory stress, which is part of why it's paired with niacinamide and tranexamic acid here rather than either active alone.

Permeability: Water-Permeable (wudu-compatible). As a fast-absorbing, watery gel-fluid ampoule with no film-forming or occlusive ingredients in its confirmed INCI, water should reach the skin normally during ablution.

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: "A higher niacinamide percentage always means more irritation." REALITY: Tolerability depends heavily on the surrounding formula's pH buffering and companion soothing ingredients — like the centella here — not the raw percentage alone, though anyone new to actives should still introduce it gradually.

MYTH: "The tingling from spicule ampoules means the product is damaging your skin." REALITY: Spicules create temporary, microscopic surface-level channels to aid absorption; the sensation is a mechanical one, not chemical burning, and it typically fades within a minute as skin adjusts — though it should never escalate into persistent burning.

DIY risk: Some people try mixing raw niacinamide powder or high-strength Vitamin C at home to "boost" a serum like this — unbuffered DIY mixes can shift the pH dramatically and cause real irritation, and there's no way to verify the purity or concentration of a home-mixed ingredient.

Sugar cane burning season (July-November): PM2.5 rises during the harvest burn period. This ampoule's centella and Ascorbyl Glucoside content offer genuine antioxidant support against that particulate stress, so daytime use during this season is reasonable, followed by sunscreen as the real primary defense.

Hard water note: Mauritius tap water hardness varies by region; hard water can leave a light mineral film on skin after cleansing. Following your cleanser with a toner before this ampoule helps counteract that residue so the ampoule absorbs evenly rather than sitting on a filmy surface.

*Centella-derived actives (madecassoside, asiaticoside-type compounds) are well studied as a class, but since this exact SKU's centella concentration isn't published, we grade it Moderate rather than Strong.

Delivery system: The formula contains Hydrolyzed Sponge — processed marine sea-sponge spicules averaging a few microns in size. In plain terms, these create microscopic, temporary channels in the outer skin layer that help the niacinamide and other actives absorb rather than sit on the surface; this is also what causes the brief tingling sensation on application.

Full INCI list (via third-party ingredient database, cross-referenced against brand/retailer product descriptions): Water, Butylene Glycol, Niacinamide, 1,2-Hexanediol, Ascorbyl Glucoside, Propanediol, Carbomer, Methylpropanediol, Tromethamine, Xanthan Gum, Tranexamic Acid, Centella Asiatica Extract, [--- Estimated 1% Line ---] Polyglutamic Acid, Hydrolyzed Sponge, Disodium EDTA, Citric Acid, Sodium DNA, Ethylhexylglycerin, Tocopheryl Acetate, Panthenol, Madecassoside.

*The 1% line above is an estimate based on typical usage rates for the ingredient types involved (thickeners, chelators, and pH adjusters are usually sub-1%), not a lab-confirmed cutoff — treat it as a reasonable guide, not an exact figure. This means the Hydrolyzed Sponge spicules and Madecassoside likely sit at a lower concentration than the headline actives above the line, which is normal for a delivery-technology ingredient and a supporting phytochemical respectively, not a sign either is ineffective.

Preservative system: 1,2-Hexanediol and Ethylhexylglycerin — a paraben-free, glycol/glycerin-ether-based preservative pairing common in modern K-beauty formulas.

Fragrance status: Fragrance-Free. No Parfum, Fragrance, or named essential oil appears anywhere in the confirmed 21-ingredient INCI.

Scent description: No deliberately added scent; a faint, neutral "serum" smell from the base ingredients is normal.

EU 26 allergen screen: None of the EU's 26 listed fragrance allergens (linalool, limonene, geraniol, citral, eugenol, coumarin, and the rest) appear in the confirmed INCI.

Alcohol disclosure: Alcohol-Free. No ethanol, denatured alcohol, or drying alcohol appears in the INCI — Butylene Glycol, Propanediol, and Methylpropanediol are all non-drying glycol humectants, not alcohols in the irritant sense.

Halal: *Self-assessed by Adilsons based on the now-confirmed 21-ingredient INCI: no ethanol from fermentation and no porcine-derived ingredients are detected. One ingredient, Sodium DNA, is conventionally sourced from fish milt/roe (commonly salmon or herring) — aquatic-animal-derived material generally considered permissible in most schools of Islamic jurisprudence, but this is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars before use.

Vegan: This product should NOT be labeled Vegan. The confirmed INCI contains Sodium DNA, an ingredient conventionally derived from fish milt/roe — an animal-derived source. SKIN1004's parent company Craver Co., Ltd is PETA-listed brand-wide for cruelty-free and vegan status, but that brand-wide listing does not override what a specific formula's own ingredient list shows, and we would rather flag this discrepancy than print a Vegan-Friendly badge we can't back up for this exact SKU.

Cruelty-free: SKIN1004's parent company is listed on PETA's own published Beauty Without Bunnies database, which we verified directly against the certifier's listing — a real third-party certification, not a self-assessment. *The brand also sells through Tmall in mainland China, where post-market animal testing can legally apply; cross-border e-commerce sales may be exempt, and which channel applies to this specific Adilsons SKU has not been confirmed.

Microplastic status: Microplastic-Free. Carbomer and Xanthan Gum are the formula's thickeners; neither is a microplastic polymer, and no polyethylene, nylon, or acrylate-copolymer microbead ingredient appears in the INCI.

MFDS classification: Niacinamide is one of the small set of ingredients South Korea's MFDS recognizes as a functional-cosmetic active for brightening at a qualifying concentration. Whether this exact SKU carries its own formal MFDS functional-cosmetic registration number was not independently located this session, so we present this as ingredient-class context rather than a confirmed per-product registration.

Whitening translation: The Korean "미백" (mibaek) classification means regulation of melanin production — fading dark spots to reveal your natural tone. It does not bleach skin or change your natural complexion.

Clinical evidence: The brand and multiple third-party retailers report a commissioned clinical test on the spicule-delivery system showing a 132.8% higher active-absorption rate versus a spicule-free control, plus reported improvements after continued use — brightness up roughly 3%, tone uniformity up roughly 8.3%, yellow-tone reduction of roughly 6.3% at 2 weeks, and pore size/depth/count improvement at 4 weeks.*

*These figures are brand-commissioned test results as reported by the brand and repeated across several third-party retailer product pages found during our research; the exact commissioning lab's name was reported inconsistently across the sources we found this session, and we could not independently verify the study or locate an independently peer-reviewed publication. Treat these as brand-reported claims, not independently replicated science.

Evidence confidence: Medium. Niacinamide's and tranexamic acid's mechanisms for sebum regulation and pigment control are backed by a large, independent body of dermatological literature; the specific percentage results above are brand-commissioned and not independently peer-reviewed.

Shelf life and Period-After-Opening figures commonly printed on this format elsewhere were not independently re-confirmed for this exact batch this session, so no specific month figures are stated here — check the batch code printed on your unit's box for the brand's own dating.

Fungal Acne Safety: FA-Safe. We cross-checked the full confirmed INCI against known Malassezia-feeding ingredient categories (fatty acid esters, fatty alcohols C11-C24, polysorbates, glucose/fatty-acid esters) and found none present. Tocopheryl Acetate appears near the end of the list at a low concentration; most fungal-acne-safety trackers consider it low-risk at this position, but very FA-reactive users may still wish to patch test.

Assessment: Low. As a watery, fast-absorbing ampoule, pilling is uncommon unless it's layered over a thick, still-damp occlusive or silicone-heavy product.

Mitigation: Apply to slightly damp (not dripping) skin, wait the full 30-60 seconds, and pat rather than rub if you notice any balling of product.

Niacinamide-based formulas are generally chemically stable and don't oxidize the way a pure L-Ascorbic Acid Vitamin C serum does, so a color shift toward yellow-brown is a more meaningful spoilage signal here than it would be for many other actives. Ascorbyl Glucoside is a more stable Vitamin C derivative than pure L-Ascorbic Acid but can still degrade with heat and light exposure. Store away from direct sunlight and vehicle-level heat, both common risks in a Mauritius climate.

Spoilage signs: Noticeable color darkening, an off or sour smell, or visible separation that won't remix on shaking. When in doubt, discard.

Patch test: Apply a small amount to your inner forearm, wait 24 hours, then test behind the ear for another 24 hours before full facial use — this is especially worth doing given the spicule texture's tingling sensation, so you know what to expect on your face.

72-hour barrier reset (if reaction occurs): Stop all actives. For 72 hours, use only a gentle cleanser and a plain moisturizer — no acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: Hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care immediately.

1) Applying more than 2-3 drops thinking it will speed up brightening — it just increases tingling risk. 2) Skipping sunscreen while using a brightening active, which re-triggers the pigmentation being treated. 3) Rubbing the product in vigorously instead of patting, which increases irritation given the spicule texture.

4) Using it on freshly-popped or actively inflamed acne lesions, where the spicule mechanism can aggravate raw skin. 5) Expecting overnight results — this operates on a multi-week epidermal turnover timeline, not a multi-day one.

Overuse threshold: Using it more than twice daily provides no additional benefit and raises the odds of irritation.

Usage math: At 2-3 drops per application, a 9ml bottle provides roughly 45-60 applications.

Lifespan: Used once daily, this lasts approximately 6-8 weeks; used twice daily (AM and PM), approximately 3-4 weeks. Using more than the recommended dose per application shortens this without improving results.

Reorder timing: If you've confirmed this formula suits your skin, the same formula is also carried in a 30ml full-size, which is worth planning for once you're a few weeks into this trial size rather than waiting until it's fully empty.

This ampoule does the "treat" job in a routine — sebum regulation and pigment fading via spicule-assisted delivery — so it needs a prep step before it and a seal step after it to actually perform well day to day.

AM: 1) Cleanse (optional) → 2) Toning Toner, 5-8 drops, wait 10-20s → 3) This ampoule, 2-3 drops, wait 30-60s → 4) Air-Fit Suncream Light SPF30, two-finger rule.

PM: 1) Ampoule Foam cleanser → 2) Toner (optional) → 3) This ampoule, 2-3 drops, wait 30-60s → 4) Hyalu-Cica Moisture Cream to seal.

If your skin is barrier-compromised right now: pause this ampoule and use the pure Centella Ampoule 55ml alone until stinging/tightness resolves, then reintroduce this one. If you're in air conditioning all day: add the Hyalu-Cica Moisture Cream underneath, since this ampoule's humectants alone don't carry a strong enough load to fight AC-driven moisture loss on their own.

Bundle — Boosting Shot Duo (for a layered PM active routine): This ampoule + Retinol 0.2 Boosting Shot Ampoule 9ml — alternate the retinol on 2-3 non-consecutive nights per week, use this niacinamide ampoule on the remaining nights. Why: two different pathways (retinoid turnover vs. sebum/pigment regulation) rather than two products doing the same job — do not layer both spicule-delivery ampoules in the same session, since that stacks two separate mechanical-irritation sources on the same night.

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

The recommendations above are based on formulation synergy with this ampoule, 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 ampoule is a strong choice if your primary goal is oil control, pore appearance, and PIH fading, and you want to test a 10% niacinamide plus spicule-delivery format in a small trial size before committing to a full bottle.

Gentler, no-spicule alternative: Beauty of Joseon Glow Serum: Propolis + Niacinamide — a lower-percentage niacinamide serum paired with propolis instead of centella and tranexamic acid, with no spicule texture, better suited to very reactive skin that finds the tingling sensation here too much even alongside centella.

Pure soothing focus: SKIN1004 Madagascar Centella Ampoule 55ml — no niacinamide, no spicules, just centella, for when barrier repair needs to come before any brightening active.

Choose this ampoule over the Beauty of Joseon Glow Serum if you need a higher-concentration niacinamide dose plus tranexamic acid specifically for oil control, pore appearance, and PIH, and your skin has already shown it tolerates niacinamide well.

Upgrade if: you've used a gentler niacinamide product before without irritation and want a stronger, multi-active dose; you specifically need PIH fading rather than general brightening; you want to trial a small size before buying the full 30ml.

Don't upgrade yet if: your barrier currently stings on plain moisturizer; you can't commit to daily SPF (this makes PIH-fading pointless); you're brand new to actives and have never tried a lower-concentration, non-spicule niacinamide product; you are currently mid-breakout with inflamed lesions.

If you match two or more upgrade triggers above, this is worth choosing. If not, the Beauty of Joseon alternative is sufficient and gentler. Consistency beats complexity.

This product's PRIMARY function is: sebum regulation, pore appearance, and PIH fading via 10% niacinamide plus tranexamic acid, delivered with spicule-assisted absorption. You do not need this if you already own an unopened or barely-used niacinamide or tranexamic-acid-led serum at a similar or higher concentration — finish that product first.

Inventory audit: Check for any open niacinamide- or TXA-led serum in your current stash before buying this one; buying a duplicate while an existing bottle sits half-used and eventually expires is simply waste.

Stacking assessment: Marginal Benefit if you already use a centella-only product (overlapping soothing action, but this adds the niacinamide and TXA your current product lacks). No Benefit if you already use another 10%+ niacinamide serum daily with a similar spicule or absorption-boosting mechanism.

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. All products are shipped directly to Mauritius via verified channels.

For comprehensive information about how we verify authenticity, our layered verification system, and how to check your product at home, visit our dedicated Authenticity and Trust page.

Quick verification tips: Check the batch code printed on the box against CheckFresh for a manufacture date; the front label should be matte, not glossy; the EAN-13 barcode should begin with the GS1 prefix 8809576, consistent with SKIN1004's registered distributor.

SKIN1004 is a Korean skincare brand founded in 2016 under parent company Craver Corporation, built around Madagascar-sourced Centella Asiatica as its shared hero ingredient across most of the catalog. Its "Lab in Nature" positioning pairs that centella base with clinically-oriented actives — retinol, niacinamide, azelaic acid — across different products in the range, of which this ampoule is the niacinamide-plus-tranexamic-acid entry.

Whether SKIN1004 manufactures in-house or through contract manufacturers has not been publicly confirmed in our research to date.

We could not fetch and individually read full review pages on Reddit, Amazon, or YesStyle for this exact SKU this session (our page-fetching tool was blocked by network restrictions for every domain attempted), so we are not quoting individual verbatim reviews with invented platforms, dates, or usernames. What we can report honestly, from aggregator data our search tool did surface: a third-party review aggregator (GoPicky) lists this product at approximately 4.8 out of 5 stars across roughly 540 aggregated ratings, skewed heavily toward 4- and 5-star. A skincare-ingredient site (Skinsort) includes this product on its list of fungal-acne-safe SKIN1004 ampoules, consistent with our own INCI-based FA-safety check above.

Common themes reported: a dedicated review blog covering all three "Lab in Nature" Boosting Shot Ampoules (niacinamide, matrixyl, retinol) describes a mild tingling sensation from the spicule texture on every entry in the line, noted as smoother/less pronounced than some other spicule serums on the market, with visibly smoother texture reported within the first week. A separate skincare-community discussion thread we found raised occasional breakout reports on SKIN1004 ampoules generally, which is consistent with either purging or an active-strength product simply not suiting every skin — not a defect specific to this SKU.

Sustainability: Rinse the glass bottle and dropper components before disposal, following local Mauritius recycling guidelines for mixed glass/plastic items.

Why does this ampoule tingle when other niacinamide serums don't? This formula contains Hydrolyzed Sponge — processed micro-spicules that create temporary micro-channels in the skin's surface to help the actives absorb. That mechanical sensation, not a chemical burn, is the source of the tingling, and it's a known characteristic of this entire "Boosting Shot" sub-line.

Can I use this every day? Yes, once your skin has adjusted over the first week or two — start once daily and increase to AM and PM if well tolerated.

Is this fungal-acne safe? Based on our cross-check of the full confirmed ingredient list against known Malassezia-feeding categories, yes — no problematic fatty esters or fatty alcohols are present.

What's the difference between the 9ml and 30ml sizes? Same formula and concentration; the 9ml is a trial/travel size intended to test tolerance to the niacinamide-plus-spicule combination before committing to the 30ml full-size bottle.

Can I use this with a retinol or Vitamin C product? Yes, on alternate nights or in an AM/PM split rather than the same session — see the pairing and bundle notes above for exact sequencing, and avoid combining it in the same routine as another spicule-delivery ampoule to prevent stacking two mechanical-irritation sources at once.

Niacinamide

Vitamin B3 derivative used topically for sebum control and brightening.

Tranexamic Acid

A synthetic active that interrupts a specific pathway (plasmin) involved in post-inflammatory pigment production.

Hydrolyzed Sponge

Processed marine sea-sponge spicules used as a mechanical delivery aid; creates temporary micro-channels in skin to help other ingredients absorb.

PIH

Post-Inflammatory Hyperpigmentation — dark marks left behind after a breakout heals.

PIE

Post-Inflammatory Erythema — red or pink marks from healed breakouts, caused by damaged capillaries rather than pigment.

MFDS

Ministry of Food and Drug Safety — South Korea's regulatory authority for cosmetics.

INCI

International Nomenclature of Cosmetic Ingredients — the standardized list of every ingredient in a product.

Ampoule

A concentrated treatment serum, typically applied in small drop amounts.

Assessment: Consult Oncologist. This formula is fragrance-free with a gentle, paraben-free preservative system, which are both supportive characteristics for treatment-sensitized skin.

However, 10% niacinamide is a genuine treatment-strength active, and the spicule delivery system is specifically designed to create micro-channels in the skin surface — a mechanism that may not be appropriate for skin made fragile or thin by chemotherapy or radiation, even where the ingredients themselves are otherwise gentle.

Consult your oncology care team before introducing any new skincare products during treatment.

Best for: Oily and combination skin dealing with post-breakout marks, visible pores, and excess shine in a humid climate, who want to trial a 10% niacinamide plus spicule-delivery formula before buying full-size.

Key benefits: A now-confirmed, evidence-backed 21-ingredient formula with three named actives (niacinamide, tranexamic acid, centella) rather than a two-ingredient marketing summary; fragrance-free with no EU-listed allergens; small trial size reduces the cost of testing tolerance to both the active strength and the spicule sensation.

Keep in mind: The spicule tingling is a genuine texture difference from a standard serum and isn't for everyone; clinical percentage claims are brand-commissioned, not independently peer-reviewed; results on PIH require 8+ weeks of consistent use with daily sunscreen.

Antioxidant pollution defense: Centella Asiatica extract and Ascorbyl Glucoside both carry genuine antioxidant activity, offering support against the free-radical stress of airborne particulates — relevant during Mauritius's July-November sugar cane burning season when PM2.5 rises. This is a supporting benefit alongside their primary calming/brightening roles, not a substitute for sunscreen or a dedicated antioxidant serum.
