SKIN1004 Madagascar Centella Ampoule Set - 1004DAY SIGNATURE (2025)

Values verified for this set: 100% Genuine (Adilsons policy), Fragrance-Free (confirmed absent from all four corrected ingredient lists). Halal and Vegan badges are addressed per-component in Section 26, not asserted here as a single bundle-wide claim.

Suitability for the set as a whole is the intersection of all four components' suitability — a skin type or state unsuited to even one component (see Section 13) should approach that one ampoule with caution while still using the others normally.

Pros: four genuinely different treatment jobs from one trusted base ingredient; real, in-catalog full/near-full sizes rather than sachets; fragrance-free across all four; collectible limited-edition packaging for a 1004 Day anniversary release. Caveats: two of the four components overlap in active ingredients (see above); several active concentrations are not independently confirmed; this is a limited edition, so this exact box may not be repurchasable once sold out.

Classification: YELLOW (14+ with guidance). The Centella Ampoule alone would be GREEN for any age, but the Tone Brightening, Matrixyl, and Niacinamide ampoules contain treatment-strength actives (10% niacinamide, tranexamic acid, a 10% peptide complex, a spicule delivery system) intended for skin already dealing with tone, firmness, or pore concerns that prepubescent and early-teen skin typically has not yet developed. These are not RED-tier ingredients, but they are adult/older-teen treatment actives, not basic everyday products.

If a tween or early teen wants to use only the calming Centella Ampoule from this box, that specific component is appropriate; the other three are better suited to 16+ skin genuinely experiencing the concerns they target.

All four ampoules are dropper-applied, require no rinsing, and take under a minute to apply — genuinely bedside-compatible on a low-energy night. Precise dosage is not critical (a few drops each time is forgiving). On the lowest-energy days, using only the Centella Ampoule plus a basic moisturizer is a perfectly reasonable minimum-viable routine; the other three ampoules can wait for a day with more attention to spare, since none of them is time-sensitive in the way a rinse-off product is.

Step 1 (When): AM or PM, after toner/essence — pick ONE of the four ampoules per application. Step 2 (How much): 2-3 drops or 1 pump of whichever ampoule you're using that day. Step 3 (How): pat/press into skin, wait 30-60 seconds, follow with moisturizer.

Introduce this set as the only new step in your routine, starting with the Centella Ampoule alone. Wait a full 14 days before adding the second ampoule, so you can tell which one is responsible for any reaction.

Cleanser (your own) → toner (your own) → one of the four set ampoules → moisturizer (your own) → sunscreen SPF50+ (your own, non-negotiable). In Mauritius' humid mornings, the watery Centella and Niacinamide ampoules absorb quickly without feeling heavy under sunscreen; the Tone Brightening ampoule's visible beads dissolve fully within the wait time.

Cleanser (your own, double-cleanse if wearing sunscreen/makeup) → toner (your own) → one of the four set ampoules → moisturizer (your own). The Matrixyl ampoule's tingling sensation is easiest to monitor in a PM routine when you're not immediately applying makeup afterward.

Hands deliver 100% of product; a cotton pad absorbs roughly 30-40% of it, so apply all four ampoules with clean hands, not a pad. Only use one ampoule per application — do not layer two or more of these four in the same routine.

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 rules: viscosity ladder thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait times: watery layers 10-20s, serums 30-60s, before sunscreen 10-15 minutes. Amounts: 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; sunscreen the two-finger rule for face, +1 finger for neck. If a routine pills, stings, or feels heavy, reduce layers, don't increase them.

AM Maximum Stack: gentle cleanse (optional) → toner (optional, 1-3 layers) → essence (optional) → soothing serum (this set's Centella Ampoule fits here) → antioxidant lane, pick one (this set's Tone Brightening or Niacinamide ampoule's Vitamin-C-derivative content could occupy this slot on a given day) → pigment-support lane (Tone Brightening/Niacinamide ampoule) → hydration serum lane → oil-control lane (Niacinamide ampoule) → peptide/repair lane (Matrixyl ampoule) → eye product → moisturizer → optional occlusive seal → sunscreen SPF50+ PA++++ (non-negotiable) → lip SPF. In AM, prioritize comfort and SPF adherence over stacking — in high humidity, fewer layers often perform better.

PM Maximum Stack: pre-cleanse (if needed) → oil cleanser (if SPF/makeup worn) → water cleanser → toner (optional) → essence (optional) → soothing/barrier serum → one of this set's four ampoules, placed here as the anchor treatment step → targeted serum (optional, only if non-conflicting) → moisturizer → sleeping mask (optional) → occlusive seal (optional) → spot treatment (as needed) → lip sleeping mask (optional). Do not layer two treatment actives from two different ampoules in this set on the same night; keep one ampoule per night.

One-lane rule: pick one treatment ampoule per routine from this set; barrier/hydration steps can always accompany it. If unsure, default to the Centella Ampoule and reduce layers elsewhere.

All four sit in the same layering position — thinnest-to-thickest ordering only matters relative to your toner (before) and moisturizer (after), not between the ampoules themselves, since only one is used per application.

If your skin stings on moisturizer or feels tight within 30 minutes of cleansing, your barrier is currently below threshold — start with the Centella Ampoule alone and a basic barrier-repair moisturizer before introducing the other three.

Redness/sensitivity: Centella Ampoule's Centella Asiatica Extract is a well-established calming botanical. Uneven tone/post-blemish marks (PIH): Tone Brightening and Niacinamide ampoules both target this via niacinamide (inhibits melanosome transfer) and tranexamic acid. Fine lines/firmness: Matrixyl ampoule's peptide complex supports collagen signaling over cumulative use. Enlarged pores/oil control: Niacinamide ampoule's core job.

What this set cannot do: cannot physically shrink pore size (niacinamide can reduce the appearance of oiliness that makes pores look larger, not the pore structure itself); cannot lift sagging skin; cannot lighten your natural skin tone (brightening here means fading excess pigment from marks, not changing baseline complexion); cannot replace a dedicated exfoliant for textural concerns.

The strongest synergy in this box is internal: the Centella Ampoule's calming base pairs naturally with whichever of the other three treatment ampoules you're using that day, buffering potential sensitivity. Beyond the box, the one genuinely missing role worth filling is daily SPF — see Section 37 for verified, in-stock options. We do not recommend adding another niacinamide or tranexamic-acid serum alongside this set, since two of its own four components already cover that pathway (see Section 39).

Chronic stress elevates cortisol, which can worsen visible redness and trigger inflammatory breakouts. The Centella Ampoule's calming, barrier-supportive role makes it a reasonable choice to fall back on specifically during stressful or flare-prone stretches, while the more active-forward ampoules (Matrixyl, Niacinamide, Tone Brightening) are better suited to calmer, more stable weeks.

All four ampoules are water-thin to light-fluid, non-occlusive leave-on serums with no film-forming silicones — Water-Permeable (wudu-compatible) once absorbed (allow the 30-60 second wait time first). This assessment is based on the products' physical properties; rulings on wudu validity vary between scholars, so consult your own trusted Islamic authority for a definitive answer.

MYTH: "A tingling sensation means the product is working harder." REALITY: The tingling from the Matrixyl and Niacinamide ampoules comes from the physical micro-spicule delivery system creating temporary micro-channels, not from the actives themselves being more potent — persistent burning is a sign to stop, not a sign of extra efficacy.

MYTH: "More ampoules layered together means faster results." REALITY: Using more than one of this set's four ampoules in the same application increases redundancy and irritation risk without adding proportional benefit — pick one per routine.

Mauritius tap water hardness varies by region; a pH-balancing toner used before any of these ampoules helps counteract the tight, filmy feeling hard water can leave after cleansing.

Centella Ampoule (55ml) — Full INCI (cross-corroborated via independent retailer/lab-listing sources; WebFetch to primary sources was blocked this session, so treat as medium confidence): Water, Glycerin, Butylene Glycol, Centella Asiatica Extract, 1,2-Hexanediol, Cellulose Gum, Ethylhexylglycerin. Only 7 ingredients total; no estimated-1%-line marker is meaningful at this length. Centella Asiatica Extract concentration is not publicly disclosed.

Adilsons' own current live listing for this SKU states a different ingredient order (Centella Asiatica Extract listed first, labelled "100%"); independent cross-corroboration consistently places Water first. The live listing's ordering is treated as unverified here.

Tone Brightening Capsule Ampoule (50ml) — Full INCI (independently cross-referenced this session; medium confidence, not a direct fetch): Water, Butylene Glycol, Niacinamide, Glycerin, Tranexamic Acid, 1,2-Hexanediol, Betaine, Centella Asiatica Extract, Zea Mays (Corn) Starch, Xanthan Gum, Microcrystalline Cellulose, Mannitol, Panthenol, Pentylene Glycol, Ethylhexylglycerin, Hydroxyethylcellulose, Madecassoside, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Arginine, Hydrogenated Lecithin, Xylitylglucoside, Anhydroxylitol, Xylitol, Glucose, 3-O-Ethyl Ascorbic Acid, Lactobacillus Ferment. Niacinamide and Tranexamic Acid concentrations are not publicly disclosed with confidence.

This corrects a prior internal record that had copied a "Gelatin"-containing list from this product's own live Shopify description — that list could not be independently corroborated and is not used here.

Matrixyl 10 Boosting Shot Ampoule (30ml) — Full INCI (independently confirmed matching across 3+ sources this session; medium confidence): Water, Butylene Glycol, Hydrogenated Polyisobutene, Glycerin, 1,2-Hexanediol, Glyceryl Stearate SE, Cetearyl Alcohol, Sorbitan Stearate, Carbomer, Cetearyl Olivate, Sorbitan Olivate, Tromethamine, Sodium Lactate, Inulin Lauryl Carbamate, Polysorbate 20, Hydrolyzed Sponge, Adenosine, Disodium EDTA, Hydrolyzed Hyaluronic Acid, Anemarrhena Asphodeloides Root Extract, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Panthenol, Madecassoside, Centella Asiatica Extract. Matrixyl 3000® peptide complex is stated as 10%; Anemarrhena Asphodeloides Root Extract (Volufiline™) as approximately 5% — both brand/retailer-stated, not independently lab-verified.

Niacinamide 10 Boosting Shot Ampoule (30ml) — Full INCI (independently cross-referenced this session; medium confidence, replacing a materially inaccurate prior record — see Section 27): Water, Butylene Glycol, Niacinamide, 1,2-Hexanediol, Ascorbyl Glucoside, Propanediol, Carbomer, Methylpropanediol, Tromethamine, Xanthan Gum, Tranexamic Acid, Centella Asiatica Extract, Polyglutamic Acid, Hydrolyzed Sponge, Disodium EDTA, Citric Acid, Sodium DNA, Ethylhexylglycerin, Tocopheryl Acetate, Panthenol, Madecassoside. Niacinamide is stated at 10% in the product's own name, consistent with its position early in the ingredient list.

Preservative systems: 1,2-Hexanediol and Ethylhexylglycerin (Centella Ampoule, Matrixyl ampoule); 1,2-Hexanediol and Pentylene Glycol/Ethylhexylglycerin (Tone Brightening ampoule); 1,2-Hexanediol (Niacinamide ampoule) — all mild, non-paraben preservative approaches.

All four components are Fragrance-Free — no Fragrance/Parfum or named essential oil appears in any of the four corrected ingredient lists, and none carry a detectable scent beyond a faint, neutral herbal note from the Centella extract itself. No EU 26 fragrance allergens were detected in any of the four lists. None of the four contains drying alcohol (Denatured Alcohol/Alcohol Denat.) as a leading ingredient.

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

Vegan: Self-assessed by Adilsons based on available INCI data for all four components. No animal-derived ingredients detected in any of the four lists (this corrects a prior internal record that had flagged a since-unconfirmed Gelatin ingredient for the Tone Brightening Capsule Ampoule). This is NOT a formal vegan certification by The Vegan Society or an equivalent body.

Cruelty-Free: SKIN1004 is listed on PETA's public "Beauty Without Bunnies" cruelty-free database, which we verified directly against the certifier's own published listing — this is 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, but which channel applies to any given Adilsons unit has not been confirmed.

Microplastic-Free: Yes across all four — the Tone Brightening ampoule's visible beads are Microcrystalline Cellulose and Corn Starch, both biodegradable, not plastic microbeads.

None of the four components' MFDS Functional Cosmetic registration status could be independently confirmed this session — the live Shopify listings for the Tone Brightening and Matrixyl ampoules assert functional classifications, but these are brand/store-stated, not registry-verified. Evidence tier: the Boosting Shot line's "132.8% higher absorption vs. spicule-free control" claim surfaced consistently across independent brand/retailer marketing copy this session, but the underlying study, sample size, and institution could not be independently located or verified — treat as a brand marketing claim, not a confirmed clinical result.

This box is SKIN1004's official "1004 Day" anniversary release for 2025 — a limited-edition, collectible packaging run, not a permanent catalog set. It may not be repurchasable in this exact configuration once current stock sells through.

Assessment: Low across all four, individually. Pilling risk rises if you stack multiple heavy actives or film-forming sunscreens on top without adequate wait time — pat, don't rub, and allow the full 30-60 second wait before moisturizer, especially with the Tone Brightening ampoule's bead texture.

Store all four away from direct heat and humidity — a bathroom cabinet rather than a windowsill, given Mauritius' climate. The Tone Brightening ampoule's visible beads dissolving unevenly or the liquid turning notably darker/yellow beyond its normal faint tint are signs to discontinue. When in doubt, discard rather than continue using a product that has changed color, smell, or texture.

Patch-test each ampoule separately on the inner forearm for 24 hours before facial use — never patch-test "the set" as one formula, since a reaction needs to be traceable to one specific ampoule. If any reaction occurs: stop that specific ampoule, run a barrier-only routine (gentle cleanser, plain moisturizer, mineral SPF) for 72 hours, then reintroduce one product at a time with a 14-day gap. Emergency stop signals for any component: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care.

Layering more than one of this set's four ampoules in the same application; treating the box as a complete routine and skipping a separate moisturizer or sunscreen; introducing all four ampoules in the same week rather than one at a time; assuming the Tone Brightening and Niacinamide ampoules are fully independent tools when they share overlapping actives.

At roughly 2-3 drops per use, once daily if used exclusively (more realistically, in rotation with the other three): the 55ml Centella Ampoule and 50ml Tone Brightening ampoule offer the most uses per bottle; the two 30ml Boosting Shot ampoules deplete faster if used as your primary daily step. Because this is a rotating set rather than a single daily product, the four components will not empty at the same rate — expect the 30ml ampoules to run out first if you favor them.

This set supplies the treatment step; a cleanser, moisturizer, and daily SPF50+ complete the routine around it. Recommendations below are stock-verified via Shopify search, not chosen for margin — if a pairing doesn't exist in catalog, we say so, and if you already own an equivalent, use what you have first.

Cleanser — primary: SKIN1004 Madagascar Centella Ampoule Foam 125ml (same-brand, same Centella base). Alternatives: Beauty of Joseon Green Plum Refreshing Cleanser 100ml, Anua Heartleaf Succinic Cleansing Foam 150ml, COSRX Low pH Good Morning Gel Cleanser 150ml.

Moisturizer — primary: Beauty of Joseon Dynasty Cream 50ml. Alternatives: Anua Birch Moisture Boosting Cream 50ml, Anua Daily Relief Lotion 200ml, SKIN1004 Madagascar Centella Probio-Cica Enrich Cream 50ml (low stock — verify before ordering).

Sunscreen — primary: SKIN1004 Hyalu-Cica Water-Fit Sun Serum 50ml SPF50+ PA++++ (same brand). Alternatives: Beauty of Joseon Relief Sun: Rice + Probiotics 50ml, SKIN1004 Tone Brightening Tone-Up Sunscreen 50ml (reinforces the brightening ampoule's work), Anua Heartleaf Silky Moisture Sun Cream 50ml.

After purchasing, you will receive our skincare education email series covering this set in depth. The recommendations above are based on formulation synergy and genuinely missing routine roles, not on margin or stock levels — if you already own a product that fills the same role, use what you have first.

If you know your concern is narrow and stable — for example, only redness, with no interest in brightening, firming, or pore care — the standalone SKIN1004 Madagascar Centella Ampoule 100ml delivers more of exactly that single formula for less handling of separate bottles. If you want a similar four-ampoule variety format but at a uniform, smaller 30ml size across all four with a different formula spread (calming, brightening, pore-care, hydration rather than firming), the brand's separate Madagascar Centella Ampoule Kit (30ml x4) is a genuine in-catalog alternative — trade-off: no dedicated peptide/firming formula in that kit, and a smaller 30ml Centella Ampoule portion than this set's 55ml.

Choose this 1004 Day Signature Set over the standalone 100ml Centella Ampoule if you need broader coverage: calming plus brightening plus firming plus pore care, not just calming alone.

If you match either of these — you want more than one treatment job covered, or firming/peptide support specifically — this set is worth choosing. If you only want the single calming formula, the plain 100ml Centella Ampoule is simpler and cheaper per-use for that one job.

This set's primary function is a rotating treatment-step wardrobe. You do not need it if you already own full bottles of all four exact formulas at these sizes — finish those first. Within the box itself: the Tone Brightening Capsule Ampoule and Niacinamide 10 Boosting Shot Ampoule share niacinamide and tranexamic acid as core actives — using both regularly provides Marginal Benefit at best over using just one of the two, not Significant Benefit. The Centella Ampoule and Matrixyl ampoule each occupy a genuinely distinct pathway (calming; peptide/firming) with no internal overlap.

Quick checks for this set: genuine dropper tips have a slight bend (a straight, tall tip is a common counterfeit sign); front labels should be matte white, not glossy or greyish; each bottle's batch code can be checked at CheckFresh; EAN-13 barcodes should begin with GS1 prefix 8809576.

SKIN1004 is a South Korean skincare brand founded in 2016, owned by parent company Craver Corporation, built around Madagascar-sourced Centella Asiatica as its hero ingredient across most of the catalog. Its "Lab in Nature" sub-line — which includes this set's Matrixyl and Niacinamide Boosting Shot ampoules — pairs single, named clinical actives (retinol, niacinamide, peptides, azelaic acid) with the same Centella base used across the brand's core range. SKIN1004 is listed on PETA's Beauty Without Bunnies cruelty-free database.

Independently-sourced reviews for this exact 4-piece "1004 Day" set were not found — it is a recent, limited-edition release. Reviews for the individual components: on Walmart's listing for the 55ml Centella Ampoule, an aggregate of 196 ratings averages 4.5 out of 5 stars, with reviewers describing it as lightweight, fast-absorbing, and calming for sensitive/redness-prone skin. For the Tone Brightening Capsule Ampoule, two individually-sourced skinsort.com user reports diverge: one reactive/sensitive-skin user reported no new breakouts and gradual fading of post-blemish marks after six weeks; another reported small bumps appearing on the forehead after about one week, resolved with a separate treatment. No independently-verifiable reviews were located for the Matrixyl or Niacinamide Boosting Shot ampoules beyond aggregated marketing-style summaries — we state this plainly rather than inventing quotes.

Note: Adilsons' own existing live listings for the Tone Brightening and Niacinamide ampoules separately contain review quotes attributed to specific platforms and dates that could not be independently traced or verified during this research and, given other confirmed inaccuracies on those same listings, should not be treated as genuine.

Sold together in a collectible, limited-edition outer gift box for the brand's "1004 Day" anniversary event. Glass components should be wrapped separately when traveling.

Do I use all four ampoules together? No — use one per application, rotating by what your skin needs that day.

Which one should I start with? The plain Centella Ampoule, for the first 14 days, before introducing the others one at a time.

Is this a complete skincare routine? No — it covers only the treatment/ampoule step. You still need a cleanser, moisturizer, and daily sunscreen.

Why do two of the ampoules feel similar? The Tone Brightening and Niacinamide ampoules both contain niacinamide and tranexamic acid — they genuinely overlap rather than being fully separate formulas.

Can I buy this exact set again once it sells out? Not guaranteed — this is a limited-edition anniversary release, not a permanent catalog item.

Best for: a SKIN1004 fan or K-beauty shopper who wants four genuinely different, full-usable-size treatment ampoules (calming, brightening, firming, pore care) in one collectible limited-edition box, and whose skin's needs shift enough week to week to make rotation useful.

Key benefits: real 55ml/50ml/30ml/30ml sizes rather than sachets; four distinct routine roles from a trusted, fragrance-free base; two components (Centella, Matrixyl) with no internal redundancy at all.

Keep in mind: two components (Tone Brightening, Niacinamide) overlap in active ingredients; this set includes no cleanser, moisturizer, or sunscreen; several active concentrations are brand-stated rather than independently lab-confirmed; this is a limited edition that may not be repurchasable once sold out.

Assessment: Consult Oncologist before use. All four components are fragrance-free with relatively minimal preservative systems and no retinoids, which is favorable, but none has been specifically evaluated for oncology-sensitized skin, and the Matrixyl/Niacinamide ampoules' spicule delivery system creates physical micro-channels that may not be appropriate during active treatment. Consult your oncology care team before introducing any new skincare products during treatment.

This product set must be introduced one ampoule at a time. Wait at least 10-14 days between adding each new one, so any reaction can be traced to a specific ampoule.

Antioxidant pollution defense: Madecassoside (present in the Centella, Tone Brightening, and Matrixyl ampoules) and Ascorbyl Glucoside/3-O-Ethyl Ascorbic Acid (Vitamin C derivatives in the Niacinamide and Tone Brightening ampoules) both contribute mild antioxidant support against everyday environmental stress, relevant during Mauritius' July-November sugar cane burning season when PM2.5 rises.

Hard water interaction: Neutral — none of the four ampoules is designed to specifically counteract Mauritius' regional hard-water residue; a pH-balancing toner beforehand remains the more relevant step for that.

Impact: Neutral to mildly supportive. The Tone Brightening Capsule Ampoule contains Lactobacillus Ferment — a POSTBIOTIC (beneficial metabolites from fermentation, not live bacteria). This is a genuine ferment ingredient, not a live-culture claim, and is not expected to disrupt the skin microbiome.

End of Week 2 decision point: any persistent redness or burning from the Centella Ampoule alone? This is uncommon — if it happens, pause entirely and reassess before continuing to any other component. No reaction → proceed to Week 3 as planned.
