Unconditional Satisfaction GuaranteeNo Shipping Fees Above 302 Months to Decide. Returns Simplified.This is a 9ml trial-size ampoule delivering 10% Niacinamide alongside Tranexamic Acid and Madagascar Centella Asiatica Extract, carried into skin by Hydrolyzed Sponge micro-spicules that create temporary micro-channels for absorption. It targets excess sebum, enlarged-looking pores, and post-breakout dark marks (PIH) without a heavy or tacky feel in Mauritius humidity, and its full 21-ingredient list is fragrance-free with no EU-listed fragrance allergens. Do not buy this if you need a full-size everyday serum (this is a 9ml trial format), you are currently mid-breakout with active inflamed lesions (spicules can irritate raw skin), or you need a strictly vegan formula see the ingredient note on Sodium DNA below.

| Attribute | Detail |
|---|---|
| Brand | SKIN1004 |
| Product Type | Ampoule / concentrated treatment serum |
| Net Volume | 9ml (trial size; a 30ml full-size of this same formula is also carried by Adilsons) |
| Key Actives | Niacinamide (10%), Tranexamic Acid, Centella Asiatica Extract, Ascorbyl Glucoside |
| Skin Types | Oily, combination, normal; usable by dry/sensitive skin with a moisturizer layered over |
| Primary Concern | Excess sebum, uneven tone, post-inflammatory hyperpigmentation (PIH) |
| AM/PM Suitability | Both |
| Routine Complexity | Straightforward |
| MFDS Classification | Niacinamide is a recognized Korean MFDS functional-cosmetic active for brightening in general; a SKU-specific functional registration number was not independently located this session* |
*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.
Age and Tween Suitability (Parental Guide)
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.
Low-Energy and Burnout Viability (For tough days)
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.
Quick Start (60-Second Essentials)
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.
AM Routine Guide (Morning sequence)
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.
PM Routine Guide (Evening sequence)
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.
How to Use (Amounts, technique, and tips)
| Area | Amount |
|---|---|
| Full face | 2 drops |
| Face + neck | 2-3 drops |
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.
Routine Encyclopedia (Where every product type fits)
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 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.
Viscosity and Layering Science (Where it fits)
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.
Weekly Planner (Scheduling actives)
| Day | AM | PM |
|---|---|---|
| Mon-Sun | Optional this ampoule | This ampoule (primary slot) |
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.
What to Expect (Results timeline)
| Phase | Timeframe | What You Will Notice |
|---|---|---|
| Immediate | 0-24 hours | A brief tingling from the spicule texture on first contact, plus skin feeling smoother; both are transient, not structural. |
| Adjustment | Week 1-2 | Possible mild tingling as skin acclimates to both the 10% niacinamide and the spicule delivery system; discontinue if burning persists beyond 30 seconds. |
| Epidermal Turnover | Week 4-6 | Brand-commissioned testing reports visible improvement in pore size, depth, and count around this window; first real changes in oil control typically align here. |
| Dermal Remodeling | Week 8-16 | Fading of stubborn PIH marks, provided daily SPF is maintained alongside it. |
| Maintenance Plateau | Beyond 16 weeks | Results stabilize; continued use maintains tone and oil control but doesn’t add further gains don’t increase the dose chasing more. |
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.
Who Should Use This (Clinical triage)
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.
| Category | Guidance |
|---|---|
| PROCEED IF | Barrier feels intact, you use SPF daily, you are not pregnant/nursing, no active eczema, age 14+ |
| PAUSE IF | Barrier is compromised, no consistent SPF habit, currently purging from another new active, or mid-active-breakout with inflamed lesions |
| STOP/CONSULT IF | Active eczema or psoriasis flare, pregnant or nursing (consult your doctor first), known niacinamide or tranexamic acid allergy, or on prescription blood-thinning medication (mention topical tranexamic acid use to your doctor as a precaution) |
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.
Skin Type Compatibility
| Skin Type | Compatibility | Notes |
|---|---|---|
| Oily/Combination | Excellent | Primary target audience; sebum-regulating and pore-refining action is most noticeable here. |
| Normal | Good | Works as a general tone-evening step; no adjustment needed. |
| Dry | Compatible with adjustment | Layer under a richer moisturizer to avoid any tightness; the spicule tingle may feel more pronounced on a dehydrated barrier. |
| Sensitive | Caution | Centella’s calming presence helps, but 10% niacinamide plus spicule texture can tingle noticeably on first use patch test first. |
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.
Targeted Concerns (What it treats)
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.
Best Paired With (Synergistic pairings)
Every recommendation below was checked against Adilsons’ live catalog before being included no invented handles.
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.
Hormonal Cycle Synchronization
| Phase | Days (approx.) | Skin Behavior | Use This Product? |
|---|---|---|---|
| Follicular | 1-13 | Oil production typically lower | Yes, standard use |
| Ovulatory | 14-16 | Oil rises with estrogen/testosterone shift | Yes, especially useful here |
| Luteal | 17-28 | Progesterone rises; pores may feel congested, breakouts more likely | Yes sebum-regulating action is most valuable in this window |
| Menstrual | 1-5 (cycle restart) | Skin often more reactive/sensitive | Continue at reduced frequency if the spicule tingle feels sharper than usual |
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.
Stress, Cortisol and Your Skin
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.
Wudu and Prayer Compatibility
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 Replacement (Common misconceptions)
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.
Climate Fit for Mauritius
| Season | Conditions | How to Adjust |
|---|---|---|
| Summer (Dec-Mar) | High heat and humidity | Use as-is; the lightweight texture won’t add heaviness on top of natural sweat/oil. |
| Winter (Jun-Sep) | Cooler, drier air | Layer a richer moisturizer over it to offset any extra dryness. |
| Cyclone Season (Jan-Mar) | Fluctuating humidity indoors/outdoors | Keep the routine simple; avoid stacking extra actives during unstable weather stress on skin. |
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.
Complete Ingredient Transparency
| Ingredient | Concentration | Evidence Grade | Source |
|---|---|---|---|
| Niacinamide | 10% (per product name; corroborated by third-party INCI listings) | Strong | Synthetic (Vitamin B3 derivative) |
| Tranexamic Acid | Not disclosed | Strong (for PIH) | Synthetic |
| Centella Asiatica Extract | Not disclosed | Moderate* | Plant |
| Ascorbyl Glucoside | Not disclosed | Moderate | Synthetic Vitamin C derivative |
*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.
Allergens and Fragrance Disclosure
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.
Conscious and Permissible Formulation
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.
Evidence, Regulation and Claims
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 “” (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.
