Unconditional Satisfaction GuaranteeNo Shipping Fees Above 302 Months to Decide. Returns Simplified.SKIN1004 Madagascar Centella Retinol 0.2 Boosting Shot Ampoule (9ml) is a PM-only dual-retinoid ampoule combining 0.2% Retinol with Retinal (exact concentration not disclosed) and micro-spicule technology, plus soothing Madagascar Centella Asiatica and Madecassoside. It works by accelerating epidermal cell turnover to smooth texture, refine the look of pores, and soften early fine lines, while the spicules physically create micro-channels that help the actives penetrate rather than sit on the surface. In Mauritius’s heat and humidity, this reads on skin as a lightweight, fast-absorbing fluid rather than a heavy “anti-aging cream” feel. Do not use this product if you are pregnant, trying to conceive, or breastfeeding see the Safety Notice below.
Important Safety Notice:
This product contains Retinol and Retinal, which are contraindicated during pregnancy and nursing. If you are pregnant, planning to become pregnant, or breastfeeding, do not purchase this product. See the Safety and Patch Test Protocol section below for verified in-catalog alternatives.
This is an active-strength product. If your skin currently stings when you apply moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking, your barrier needs repair first using a dual-retinoid ampoule now will make things worse, not better.

| Attribute | Detail |
|---|---|
| Brand / Line | SKIN1004 “Lab in Nature” derma-active line |
| Net Volume | 9ml (trial size; a 30ml full size exists in the brand’s wider range, not currently stocked by Adilsons) |
| Key Actives | Retinol 0.2% (brand-stated) + Retinal (concentration not disclosed) + micro-spicules |
| Skin Types | Combination, oily, and resilient normal skin; sensitive skin should buffer (see How to Use) |
MFDS Classification: not confirmed. The INCI does include Adenosine, an ingredient MFDS recognizes for wrinkle-improvement functional claims at a set concentration, but we could not verify whether this specific SKU carries that formal registration, so we are not stating it as fact.
AM/PM Suitability: PM only. Routine Complexity: Advanced this is a dual-retinoid formula with physical spicules, not a beginner single-active serum, even though the labeled percentage (0.2%) is on the gentler end of retinol strengths.
Starting a retinoid for the first time can feel discouraging when the “retinol uglies” (flaking, tightness, a few small bumps) show up in week two that reaction is common and usually temporary, not a sign you did something wrong.
Pros: dual Retinol + Retinal formula gives two turnover pathways in one step; spicule delivery is designed to reduce the raw percentage needed for visible effect; Centella/Madecassoside/Panthenol are included specifically to buffer irritation; 9ml is a low-commitment way to trial a dual-retinoid before buying a full size.
Caveats: 9ml is genuinely small and will run out inside 6-8 weeks at recommended dosing; the dropper reportedly dispenses very little per squeeze so budget a few extra presses; this is not a suitable first-ever retinoid for someone who has never used any active before.
Age and Tween Suitability (Parental Guide)
Classification: RED. This product contains Retinol and Retinal, both Vitamin A derivatives that force faster skin cell turnover a process that skin under roughly age 16 does not yet need and is not built to buffer the way adult, fully keratinized skin is.
The packaging is a plain amber dropper bottle with no youth-targeted branding, so there is no packaging trap here the risk is purely the actives themselves, not marketing aimed at teens.
Safe alternative: SKIN1004 Madagascar Centella Ampoule 30ml (verified active in our catalog) the same Centella base with no retinoid, suitable for a basic cleanser-moisturizer-SPF routine.
Quick Start (60-Second Essentials)
“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)
Do not apply this product in the morning. Retinol and Retinal are photosensitizing sunlight degrades them and increases sun-sensitivity of the skin they’re on, so this ampoule is a PM-only step.
Your AM routine instead exists to protect the retinization work done overnight: 1) Gentle cleanse or water-only rinse 2) Optional antioxidant/hydration layer 3) Moisturizer 4) Broad-spectrum SPF, non-negotiable retinoid-treated skin is measurably more UV-reactive.
In Mauritius’s humid mornings, a hydrating serum layer (like SKIN1004 Poremizing Fresh Ampoule) draws water from the humid air rather than pulling it from deeper skin layers, so it performs well as a light AM step before sunscreen.
PM Routine Guide (Evening sequence)
Cell turnover and DNA-repair processes run highest overnight, which is the biological reason retinoids are dosed at night rather than a marketing convention.
Skin cycling placement: if you also use an exfoliating acid elsewhere in your routine, this ampoule occupies the “Retinoid night” slot in a 4-night cycle (Night 1 Acid Night 2 Retinoid Nights 3-4 Recovery) see the Conflict Solver below.
How to Use (Amounts, technique, and tips)
| Area | Amount | Notes |
|---|---|---|
| Face | 2-3 drops | Estimate the dropper is reported to draw a small volume per squeeze, so several presses may be needed |
| Neck | +1 drop | Optional, if extending the routine |
Technique: pat or press the product in rather than rubbing friction increases irritation on actively-turning-over skin. Apply only to fully dry skin; residual moisture can increase stinging with retinoids.
Wait time: 1-2 minutes before moisturizer, longer (2-5 minutes) if your skin is sensitive or new to retinoids.
Hands deliver 100% of product; cotton pads absorb approximately 30-40% of it. Use clean hands for this step, not a pad.
Frequency: start 2-3 nights per week, non-consecutive, and only increase toward nightly use once your skin shows no persistent redness or flaking at the current frequency for at least two weeks.
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.
Viscosity ladder: thinnest to thickest; water-phase before oil-phase; treatments before seals. 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 2-finger rule for face, +1 finger for neck. Hard cap rule: if the routine pills, stings, or feels heavy, reduce layers, not increase.
AM Maximum Stack (not all steps are used daily pick what your skin needs):
In AM, prioritize comfort and SPF adherence over stacking; in high humidity, fewer layers often perform better.
PM Maximum Stack:
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)
This ampoule sits in the “light fluid/serum” tier thicker than a watery toner, thinner than a lotion and is applied after any hydrating toner/essence steps but before your moisturizer.
It is a water-based emulsion phase (it contains both water-soluble humectants like Sodium Hyaluronate and oil-phase emollients like Squalane and Cetearyl Olivate held together by emulsifiers), so it layers cleanly under a cream without pilling if given its full absorption time.
Retinol and Retinal are both small molecules (roughly 286 and 284 g/mol respectively) well under the 500-Dalton threshold generally used as a rule of thumb for topical penetration, which is consistent with why this class of ingredient works at low percentages rather than needing to sit on the surface.
Multiple independent reviewers describe the formula as noticeably thick in the bottle but spreading into a thin, fast-absorbing film on skin don’t judge how much to use by how the product looks in the dropper.
Weekly Planner (Scheduling actives)
| Day | AM | PM |
|---|---|---|
| Mon | Antioxidant + SPF | This ampoule |
| Tue | SPF only routine | Recovery (moisturizer only) |
| Wed | SPF only routine | This ampoule |
| Thu-Sun | SPF only routine | Recovery / repeat pattern as tolerated |
Rest days: at least 2-3 non-retinoid nights per week while building tolerance, so the barrier has time to recover between turnover pushes.
Exceeding the recommended frequency does NOT produce faster results it produces barrier damage, which then delays results because you have to stop and repair before you can resume.
What to Expect (Results timeline)
| Phase | Timeframe | What You Will Notice |
|---|---|---|
| Immediate | 0-24h | Mild tingling from the spicules on first use, typically settling within a few minutes; skin feels smooth, not greasy |
| Adjustment | Week 1-2 | Possible dryness, flaking, or small bumps (“retinol uglies”) as turnover accelerates; discontinue if burning persists beyond 30 seconds |
| Epidermal Turnover | Week 4-6 | Smoother texture, refined pore appearance aligned with one epidermal turnover cycle |
| Maintenance | Ongoing | Results stabilize with consistent 2-4x/week use; more product does not mean more results |
The brand’s own clinical testing (via ProbeM Skin Clinical Research Center, as reported by third-party retail listings) claims improved elasticity after a single use and roughly a third reduction in the visible depth of fine lines after two weeks*.
*We could not independently verify this testing’s sample size, methodology, or peer-review status. Treat these as brand-cited figures, not independently confirmed clinical results.
Purging vs. reaction: purging shows up in your usual breakout zones, stays surface-level, and resolves in 4-6 weeks; a true reaction shows up in new areas, involves burning/swelling/hives, and gets worse rather than better stop immediately if you see the second pattern.
Who Should Use This (Clinical triage)
Before starting this product, your routine must already include a working daily moisturizer and a daily broad-spectrum sunscreen habit. Without these two foundations, a dual-retinoid ampoule causes more harm (barrier stripping, sun damage) than benefit.
| Tier | Condition |
|---|---|
| PROCEED IF | Barrier intact, consistent SPF user, not pregnant/nursing, no active eczema, age 16+ |
| PAUSE IF | Compromised barrier, no reliable SPF habit, currently purging from another active |
| STOP/CONSULT IF | Active eczema or psoriasis, pregnant or nursing, on prescription tretinoin/adapalene/isotretinoin, known retinoid allergy |
We could not confirm a lower-strength, in-stock graduated “step” product within this exact SKIN1004 retinol line at Adilsons at the time of writing, so we are not presenting a formal graduation ladder see Mindful Alternatives below for a non-retinoid pore/texture option instead.
If your skin currently stings on moisturizer or feels tight within 30 minutes of cleansing, your barrier is below the threshold this product needs. Start with the fragrance-free, retinoid-free SKIN1004 Madagascar Centella Ampoule 30ml (verified active in our catalog) first.
Skin Type Compatibility
| Skin Type | Compatibility | Notes |
|---|---|---|
| Oily / Combination | Good fit | Fast-absorbing, non-greasy finish reported by reviewers |
| Normal / Resilient | Good fit | Standard 2-3x/week build-up applies |
| Dry | Conditional | Buffer by applying over a light moisturizer initially; watch for flaking |
| Sensitive / Reactive | Caution | Micro-spicules add physical texture on top of the retinoid load patch test and start slower than usual |
In deeper skin tones (Fitzpatrick IV-VI), any retinoid that over-irritates can trigger post-inflammatory hyperpigmentation as skin heals from the irritation itself this is a reason to under-dose at first rather than a reason to avoid the product outright.
Targeted Concerns (What it treats)
Texture and enlarged pores: accelerated cell turnover clears the dead-cell buildup that makes pores look larger and skin feel rough.
Early fine lines: both Retinol and Retinal support collagen signaling over consistent use, which is the mechanism behind fine-line softening rather than an instant filler-like effect.
Mild post-inflammatory marks: faster turnover can help fade shallow, brown post-acne marks (PIH) over time, but it does little for the pink/red marks (PIE) that come from damaged capillaries those respond better to Centella or time.
What this product cannot do: it cannot physically shrink pore size (pores don’t have muscles to contract), cannot lift sagging skin, and will not lighten your natural skin tone any brightening effect is pigment-fading, not tone-changing.
Best Paired With (Synergistic pairings)
Every pairing below was checked against our live catalog and is currently active.
Pilling risk: layering a heavy occlusive balm directly on top before this ampoule has fully absorbed is the most common cause of pilling wait the full 1-2 minutes first.
Conflict Solver (Active ingredient rules)
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: run only one primary “active lane” per AM or PM routine. If you break a rule, don’t push through reduce frequency, split AM/PM, or alternate nights. If moisturizer stings or skin feels tight within 30 minutes of cleansing, pause all actives and run barrier-only for 3-7 days.
Retinoid Lane (this product):
“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 and reduce layers.
Scheduling Templates
Template A AM/PM Split (most common): AM Antioxidant lane Moisturizer SPF; PM this ampoule Moisturizer.
Template B 4-Night Skin Cycling: Night 1 Exfoliation lane; Night 2 this ampoule (Retinoid lane); Nights 3-4 Recovery (no actives).
Most beginners do better starting with Template A alone (no separate exfoliant) until the skin has 4-6 weeks of retinoid tolerance before adding an acid lane on top.
Wudu and Prayer Compatibility
Assessment: Water-Permeable (generally wudu-compatible). This is a fast-absorbing serum-style ampoule, not a heavy occlusive balm reviewers describe it absorbing fully within a minute or two and leaving a non-greasy finish, which is consistent with water reaching the skin during ablution once the product has absorbed.
If applying shortly before prayer, we’d suggest allowing the normal 1-2 minute absorption window first, the same wait time already recommended before moisturizer.
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 0.2% retinol is basically decorative and won’t do anything.” REALITY: concentration alone doesn’t determine effect delivery matters, and this formula pairs the retinol with Retinal (a more direct precursor to active retinoic acid) and a physical spicule-delivery system specifically to punch above its labeled percentage.
MYTH: “If a little retinol works, more will work faster.” REALITY: over-applying accelerates barrier damage, not results the epidermal turnover cycle has a biological floor (roughly 28+ days) that more product cannot shorten.
Climate Fit for Mauritius
| Season | Conditions | Adjustment |
|---|---|---|
| Summer (Dec-Mar) | Heat + humidity | Formula’s lightweight, non-greasy finish layers well; keep frequency steady, don’t skip SPF the next morning |
| Winter (Jun-Sep) | Drier air | Consider buffering over moisturizer more often if flaking increases |
| Cyclone Season (Jan-Mar) | High humidity swings | No specific adjustment needed for this product beyond standard SPF discipline |
This formula includes Sodium Hyaluronate, a humectant. In air-conditioned rooms for extended periods, humectants can pull moisture from your deeper skin layers instead of the air always seal this step with a moisturizer when spending long hours in AC.
Mauritius tap water hardness varies by region; a pH-adjusting toner beforehand can reduce the calcium residue that sometimes makes actives feel like they’re stinging more than they actually are.
Complete Ingredient Transparency
| Ingredient | Concentration | Evidence Grade | Mechanism |
|---|---|---|---|
| Retinol | 0.2% (brand-stated) | Strong | Converts to retinoic acid, accelerates keratinocyte turnover |
| Retinal (Retinaldehyde) | Not disclosed | Strong | One conversion step closer to active retinoic acid than retinol |
| Madecassoside / Centella Asiatica Extract | Not disclosed | Moderate | Anti-inflammatory, supports barrier lipid synthesis |
| Panthenol | Not disclosed | Moderate | Humectant with mild anti-inflammatory effect |
| Adenosine | Not disclosed | Moderate | Supports collagen signaling; MFDS-recognized wrinkle-improvement ingredient at set concentrations |
Delivery system: “Hydrolyzed Sponge” in the INCI refers to the marine-derived micro-spicules tiny, dissolvable particles that create temporary micro-channels in the outer skin layer to help the retinoids and Centella actives absorb rather than sit on the surface. This is why the product tingles briefly on first use.
We could not find a published pH or free-acid-value figure for this product from the brand or third-party labs, so we are stating plainly: pH not publicly disclosed.
Full INCI (sourced via INCIDecoder/CosDNA aggregation, cross-checked across two independent look-ups): Water, Glycerin, 1,2-Hexanediol, Cetearyl Olivate, Squalane, Sorbitan Olivate, Carbomer, Retinol, Caprylic/Capric Triglyceride, Hippophae Rhamnoides Fruit Extract, Tromethamine, Phaseolus Radiatus Seed Extract, Hydrogenated Lecithin, Inulin Lauryl Carbamate, Sodium Polyacrylate, Retinal, Hydrolyzed Sponge, Adenosine, Sodium Hyaluronate, [— Estimated 1% Line —] Disodium EDTA, Tocopheryl Acetate, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Ethylhexylglycerin, Rosmarinus Officinalis (Rosemary) Leaf Extract, Panthenol, Madecassoside, Centella Asiatica Extract.
The 1% line placement above is our estimate based on typical INCI ordering conventions, not a brand-disclosed cutoff brands sometimes list hero actives earlier than their true concentration position for marketing reasons, so treat this marker as approximate.
Preservative system: 1,2-Hexanediol and Ethylhexylglycerin (both function as preservative-boosters/multifunctionals rather than classic parabens or phenoxyethanol).
Allergens and Fragrance Disclosure
Fragrance status: Fragrance-Free. No “Parfum,” “Fragrance,” or added essential oil appears anywhere in the declared INCI, which matches independent reviewer reports of an unscented, neutral product.
EU 26 allergen screen: none of the 26 EU-designated fragrance allergens (linalool, limonene, citral, geraniol, etc.) appear in the declared INCI.
Alcohol disclosure: Alcohol-Free in the drying-alcohol sense there is no ethanol or denatured alcohol in the list. 1,2-Hexanediol is present as a diol solvent/preservative-booster, a different chemical class from drying alcohols.
Conscious and Permissible Formulation
Halal Status: Halal-Friendly*.
*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.
One additional open question we could not resolve: “Hydrogenated Lecithin” can be sourced from either soy/sunflower (plant) or egg yolk (animal) depending on the manufacturer, and SKIN1004 does not publicly disclose the source for this SKU. We are flagging this rather than assuming a plant source.
Vegan and Cruelty-Free Status: SKIN1004 (Craver Corporation) is listed on PETA’s public cruelty-free company database under its “Beauty Without Bunnies” program, which covers both cruelty-free and vegan certification brand-wide.*
*This is a real third-party certification we verified against PETA’s own published listing, not a self-assessment. One caveat: SKIN1004 also sells through Tmall in mainland China, where post-market animal testing can legally apply. Cross-border e-commerce sales may be exempt from that requirement, but we could not confirm which sales channel applies to this exact SKU.
Microplastic Status: Free of insoluble microplastics. No polyethylene, nylon, or similar insoluble synthetic polymer particles appear in the declared INCI. Carbomer and Sodium Polyacrylate are present as water-soluble/swellable thickening polymers, which are not classified as microplastics under the EU definition.
Evidence, Regulation and Claims
MFDS Classification: not confirmed as a registered Functional Cosmetic from available sourcing see At-a-Glance above.
Clinical evidence: third-party retail listings cite brand-commissioned testing through ProbeM Skin Clinical Research Center, reporting improved absorption with the spicule technology versus a spicule-free control, and elasticity/wrinkle-appearance improvements within one to two weeks*.
*We were not able to independently verify this study’s sample size, in-vivo vs. in-vitro design, or peer-review status treat these as brand-cited figures. Evidence Confidence: Medium (named testing institution and specific figures exist, but independent verification was not available to us).
Product Identity and Provenance
| Attribute | Detail |
|---|---|
| Brand / Sub-line | SKIN1004 / “Lab in Nature” |
| Country of Manufacture | South Korea |
| Net Volume (this SKU) | 9ml |
| Also sold as | 30ml full size (not currently stocked by Adilsons) |
We found no evidence of a reformulation for this specific product, so we are not speculating about one.
Sensory and Chemical Profile
| Attribute | Detail |
|---|---|
| Texture | Thick in the bottle, spreads into a thin fluid on skin |
| Scent | Unscented (no fragrance in declared INCI) |
| Absorption | Fast; reviewers describe it as non-greasy within roughly a minute |
| Initial sensation | Mild prickly tingling from spicules, typically settling within a few minutes |
Fungal Acne Safety: FA-Conditional. Squalane and Caprylic/Capric Triglyceride in this formula are considered fungal-acne-safe. Cetearyl Olivate, Sorbitan Olivate, and Hydrogenated Lecithin are ingredients some fungal-acne-safety trackers flag as ambiguous for reactive/FA-prone skin if you know you’re FA-prone, patch test on a small area first rather than assuming either way.
Pilling Risk and Texture Mechanics
Assessment: Low-to-Medium. The formula itself absorbs cleanly, but stacking it under a heavy occlusive balm before it has fully absorbed is the most commonly reported cause of pilling.
Mitigation: apply to dry skin, wait the full 1-2 minutes, pat rather than rub, and reduce the amount of any subsequent layer if you notice balling on the skin.
