*Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram or animal-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars. Vegan claim is on the same self-assessed basis — no animal-derived ingredients detected; this is NOT a formal vegan certification by The Vegan Society or equivalent body.

Pore congestion in Mauritius is often a shame spiral: you see the texture, you scrub harder, and the skin gets angrier and shinier rather than smoother. This serum's job is to do the loosening chemically, overnight, while you do nothing.

Pros: genuinely high active load (14% PHA is unusually generous for a gentle acid), fragrance-free, single-step overnight use, niacinamide co-active for sebum/tone. Caveats: not beginner-friendly at this concentration, exact pH not disclosed by the brand, and one credible independent review describes the finish as "sticky" rather than the brand's claimed non-sticky feel — texture reception genuinely varies by user.

Classification: RED. A combined 15.2% AHA+BHA+PHA acid load is a clinical-grade exfoliating strength, not a gentle daily toner dose. Skin under roughly 16 hasn't yet developed the sebaceous gland activity and pore-congestion patterns this product is designed to treat, so the exfoliation risk (barrier stripping, sensitization) outweighs any benefit at that age.

If a younger user wants pore-care basics, a gentle non-acid option is more appropriate: Medicube's own Zero Foam Cleanser 120g (saponified fatty-acid cleanser, no acids) is a safer starting point, with PDRN Pink Cica Soothing Toner 250ml as an alternate calming follow-up — both verified in stock.

Step 1 — When: PM only, on fully cleansed, dry skin.

Step 2 — How much: 2-3 drops for the full face, or a slightly larger amount pressed onto specific congested areas.

Step 3 — How: Press or pat into skin (do not rub), wait 30-60 seconds, then follow with moisturizer.

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.

This is a PM-only product — the triple-acid complex increases sun sensitivity, and Mauritius's UV index runs high nearly year-round. Using it in the morning without an airtight SPF habit meaningfully raises sunburn and post-inflammatory pigmentation risk.

A typical AM sequence without this serum: 1) Rinse cleanse, 2) Hydrating toner (1-2 layers, 5-8 drops each, 10-20s wait), 3) Niacinamide/soothing serum if used, 4) Moisturizer, 5) SPF50+ PA++++, mandatory, non-negotiable after any night this serum was used, reapplied every 2 hours of outdoor exposure.

1) Oil cleanse if wearing sunscreen/makeup, 2) Water cleanser, 3) Optional hydrating toner (5-8 drops, wait 10-20s), 4) Zero Pore One-Day Serum — 2-3 drops, pressed in, wait 30-60 seconds, 5) Moisturizer (gel-cream for oily skin, richer cream if dry), 6) Optional occlusive seal only if AC-heavy or very dry that night.

Skin cycling integration: this serum occupies the Exfoliation lane. On a 4-night cycle: Night 1 this serum, Night 2 retinoid (if used), Nights 3-4 recovery (barrier/hydration only, no actives).

Technique: Pat/press, do not rub — friction on an acid-active serum increases irritation and degrades even application. Required skin state: fully dry skin, since acids on damp skin can penetrate faster and sting more than intended. Wait time: 30-60 seconds before moisturizer, because the triple-acid complex needs contact time at its working pH before being diluted or buffered.

Hands deliver 100% of product. Cotton pads absorb approximately 30-40%. Use hands, not a pad, for this serum.

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

Global rules: viscosity ladder 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 min if going outdoors. Amount defaults: 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 2-finger rule for face plus 1 finger for neck. Hydrators go on slightly damp skin; exfoliating acids (like this serum) go on dry skin, one lane only. If the routine pills, stings, or feels heavy — reduce layers, don't add more.

AM Maximum Stack: 1) Rinse/gentle cleanse (optional), 2) pH-prep toner (optional), 3) Hydrating toner layers 1-3 (optional), 4) Essence (optional — choose toner layering OR essence, not both if pill-prone), 5) Mist (optional), 6) Booster/soothing serum (optional), 7) Antioxidant lane — choose ONE (Vitamin C or gentler antioxidant), 8) Pigment support lane — choose ONE (TXA/arbutin/azelaic if AM-tolerated), 9) Hydration serum lane (HA/polyglutamic/beta-glucan), 10) Oil-control lane — choose ONE (niacinamide/zinc/succinic), 11) Peptide/growth-factor lane, 12) Eye product, 13) Moisturizer, 14) Optional sealing layer (dry/AC only), 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 — Zero Pore One-Day Serum], product-type default 2-3 drops, wait 1-3 minutes since this anchor is an acid/exfoliant, 9) Targeted serum (optional, only if non-conflicting), 10) Moisturizer, 11) Sleeping mask (optional, dry/barrier-support nights), 12) Occlusive seal (optional), 13) Spot treatment (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.

This is a water-thin to light-fluid gel-serum — apply after any watery toner/essence and before your moisturizer. It sits in the water phase; the small Dimethicone fraction gives a smoothing finish without pushing it into silicone-phase territory that would repel water-based layers after it.

Phase compatibility: water-phase, meaning it should be layered before any oil or heavier silicone-forward product, never after one.

Rest days: at least 3-4 nights per week with zero acids, so the barrier can rebuild. Overuse warning: do not use nightly, even if "tolerating" it well — exceeding 3-4 nights a week does not produce faster results, it produces barrier damage that shows up as tightness and increased oil production 1-2 weeks later.

Purging vs. Reaction: PURGING shows up in your usual breakout zones, stays surface-level, and resolves in 4-6 weeks — this is plausible here since acid exfoliants can accelerate the surfacing of existing congestion. A REACTION appears in NEW areas, involves burning, swelling, or hives, and worsens rather than improves — stop immediately if you see this pattern.

Before starting this product, your routine MUST already include: a consistent daily SPF habit, a gentle non-stripping cleanser, and a plain moisturizer you tolerate well. Without these foundations, this product causes more harm than benefit.

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 PDRN Pink Hyaluronic Moisturizing Cream 50ml (verified in stock) for 1-2 weeks first.

Enlarged pores: Gluconolactone (PHA) and the AHA/BHA pairing dissolve the keratin-and-sebum plugs that stretch pore openings visually, so pores look tighter once the plug is cleared — not because the pore's physical structure shrinks. Surface texture: the acid trio accelerates removal of dead corneocytes that catch light unevenly and feel rough.

Secondary benefit: Niacinamide at 2% supports mild sebum regulation and tone evenness over time.

What this product cannot do: it cannot physically shrink pore diameter (pores are fixed anatomical openings around a hair follicle — only the visible congestion inside them changes), and it cannot treat active, inflamed cystic acne, which needs a different, gentler approach until inflammation resolves.

1. PDRN Pink Hyaluronic Moisturizing Cream 50ml — follows the serum to replace moisture the acid complex draws out; PM, always after this serum. Alternates: PDRN Pink Collagen Capsule Cream 55g, Exosome Cica Cream 50ml, Zero Pore One-Day Cream 50ml (same family, gentler follow-up formula).

2. Zero Pore Moisture Sun Serum 50ml — mandatory next-morning SPF after any acid night, same Zero Pore family for a coherent routine. Alternates: Collagen Firming Sun Cream 50+SPF, Glow Collagen Sunscreen SPF50, PDRN Hydrating UV Serum.

3. Zero Foam Cleanser 120g — a gentle, acid-free cleanse the same evening keeps overall irritation load low before this serum goes on. Alternates: Zero Pore Clearing Capsule Cleansing Foam, PDRN Hydrating Gel Cleanser 200ml, PDRN Pink Niacinamide Whip Cleanser 120g.

4. PDRN Pink Cica Soothing Toner 250ml — a calming toner on recovery nights (see Weekly Planner) rebalances between acid nights. Alternates: PDRN Pink Niacinamide Milky Toner 150ml, Zero Pore Pad Mild 70pcs (gentle PHA-only, for skin cycling variety).

Pilling risk with pairings: layering this serum under a heavy silicone-forward moisturizer same night can pill if applied before the serum fully absorbs — wait the full 30-60 seconds first.

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

Universal rule — One Active Lane per routine: in a single PM routine, run only this serum's exfoliation lane, not a second strong acid or retinoid the same night. If you break this rule, don't push through — reduce frequency or alternate nights instead.

× Retinoids (Retinol/Retinal/Tretinoin/Adapalene): never same night. Use skin cycling (Night 1 this serum, Night 2 retinoid, Nights 3-4 recovery) or alternate nights.

× L-Ascorbic Acid Vitamin C: don't layer in the same routine — Medicube's own product instructions explicitly state not to use this serum simultaneously with Vitamin C products. Use the classic split: Vitamin C AM, this serum PM.

× A second AHA/BHA/PHA product (e.g. Zero Pore Pad 2.0): avoid stacking two strong exfoliants same night — over-exfoliation risk. Alternate which one you use on which night instead.

× Direct acids and peptide products: if you add a separate peptide serum on top, apply peptides first on a non-acid morning, or wait 20 minutes after this serum before a peptide layer at night — low pH can destabilize peptide bonds.

Scheduling Template (AM/PM Split): AM — antioxidant lane (Vitamin C) → moisturizer → SPF. PM — this serum (exfoliation lane) → moisturizer. On skin-cycling nights: Night 1 exfoliation (this serum), Night 2 retinoid, Nights 3-4 recovery.

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.

Pre-period breakouts happen because progesterone causes the pore lining to physically swell, narrowing the opening and trapping sebum beneath — this is exactly the congestion this serum targets, but resist the urge to overuse it during the luteal phase just because pores feel worse; overuse compounds rather than solves this.

Water-Permeable. This is a light, water-based gel-serum with only a minor Dimethicone fraction — it does not form a continuous film that blocks water contact with skin.

Applied and absorbed as directed (30-60 seconds before moisturizer), water should reach the skin normally during wudu. 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: "Using an acid serum every night gets faster results." REALITY: exceeding 3-4 nights a week strips the barrier faster than it can rebuild, which shows up as more oil production and irritation, not clearer pores.

MYTH: "This will shrink my pores permanently." REALITY: pores are fixed anatomical structures; this serum clears what's inside them, making them look smaller — the effect is maintenance-dependent, not permanent.

MYTH: "PHA at 14% must be as strong as 14% glycolic acid." REALITY: PHA molecules are larger and penetrate more slowly than AHA, so a high PHA percentage is genuinely gentler than the same percentage of glycolic acid — this is why the formula leans on PHA for its bulk.

AC environment warning: this serum carries several hyaluronic acid forms alongside the acids. In air-conditioned environments, hyaluronic acid draws moisture FROM your deeper skin layers instead of from the air — always seal with a proper moisturizer after this serum if you'll be in AC for hours.

Sugar cane burning season (July-November): PM2.5 increases during this period; since this serum is used at night and rinsed off by morning cleansing (indirectly, via your next cleanse), direct particulate adhesion risk is low — no adjustment needed beyond your normal AM cleanse.

*This ingredient appears below the estimated 1% line in the INCI list, suggesting it is present at a trace/sub-efficacious concentration. Its inclusion may be primarily for marketing rather than clinical effect.

Full INCI: Water(Aqua), Gluconolactone, Methylpropanediol, Glycerin, Propanediol, Tromethamine, Polyglycerin-3, Niacinamide, 1,2-Hexanediol, Citric Acid, Dimethicone, Butylene Glycol, C12-14 Pareth-12, Hydroxyethylcellulose, Salicylic Acid, Ammonium Acryloyldimethyltaurate/VP Copolymer, Sodium Polyacryloyldimethyl Taurate, Lecithin, Allantoin, Lactic Acid, Glycolic Acid, [--- Estimated 1% Line ---] Ethylhexylglycerin, Adenosine, Dextrin, Indigofera Tinctoria Extract, Sodium Hyaluronate, Hyaluronic Acid, Sodium Citrate, Hemerocallis Fulva Flower Extract, Gardenia Florida Fruit Extract, Hydrolyzed Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Trisodium Phosphate, Myosotis Sylvatica Flower/Leaf/Stem Extract, Pentylene Glycol, Hydroxypropyltrimonium Hyaluronate, Sodium Acetylated Hyaluronate, Centella Asiatica Extract, Madecassoside, Lactobacillus Ferment Lysate, Taraxacum Officinale (Dandelion) Leaf Extract.

This list is a WebSearch-reconstruction from incidecoder.com and skinsort.com snippets (direct page fetch blocked by network egress) — medium confidence. The 1% line placement above is an estimate based on the brand's disclosed 1% combined AHA figure, not a brand-published position marker.

Preservative system: 1,2-Hexanediol and Ethylhexylglycerin — a common multifunctional preservative/humectant pairing, not a traditional paraben or formaldehyde-releaser system.

Fragrance status: Fragrance-Free — no Fragrance/Parfum entry appears anywhere in the declared INCI, corroborated by multiple retailer listings explicitly marketing it as fragrance-free.

EU 26 allergen screen: None detected in the declared INCI — consistent with the absence of any Fragrance/Parfum entry.

Alcohol disclosure: Alcohol-Free — no denatured or drying alcohol appears in the declared INCI.

Aspirin sensitivity → Salicylic Acid (BHA): this serum contains Salicylic Acid at 0.2%. Individuals with a genuine aspirin/salicylate allergy (not just sensitivity) should patch test carefully, though topical exposure at this concentration is a far smaller systemic load than an oral dose.

Prescription interactions: if you use prescription tretinoin, adapalene, or isotretinoin, consult your dermatologist before combining — the combined exfoliation load can exceed what your barrier can tolerate.

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

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

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

Microplastic-Free: Yes — no known microplastic-classified polymers identified in the declared INCI.

MFDS classification: not confirmed as Functional Cosmetic (Korea's additional-testing tier for whitening/wrinkle/UV claims) — treated as a General Cosmetic pending evidence otherwise.

Clinical claim: the brand states a 10.8% reduction in pore appearance after one day of use. No study institution, sample size, or peer-reviewed methodology was found for this figure in any source checked.

*This claim is Marketing-Only tier — brand-commissioned or brand-stated with no independently verifiable study data behind it.

Fungal Acne Safety: FA-Conditional. No classic fatty-ester FA triggers (Isopropyl Myristate, Ethylhexyl Palmitate, Polyglyceryl esters) were identified in the reconstructed INCI, and the Dimethicone/C12-14 Pareth-12 present are generally low FA-concern. It's flagged conditional rather than clean FA-safe because over-exfoliation itself can indirectly favor Malassezia overgrowth if overused — a mechanism-based caution, not an ingredient-based one.

Assessment: Low-to-Medium. The film-forming acrylate polymers (Ammonium Acryloyldimethyltaurate/VP Copolymer, Sodium Polyacryloyldimethyl Taurate) can interact with a heavy silicone-primer or thick cream applied too soon after.

Mitigation: apply on fully dry skin, wait the full 30-60 seconds, and pat rather than rub the next layer on.

Fresh product should be clear to very slightly opalescent. A yellowed or noticeably darker tint, or a separated/curdled texture, signals the formula has broken down — discard rather than use, since degraded acid formulas can become more irritating and less effective simultaneously.

Storage: keep away from direct bathroom-shelf heat and humidity swings common in Mauritius; a bedroom drawer or cabinet extends stability versus a steamy bathroom.

Spoilage signs: color change, separation that won't remix, an off or sour smell. When in doubt, discard.

Patch test: inner forearm for 24 hours, then behind the ear for 24 hours, then begin facial use at reduced frequency (1x/week) for the first two weeks.

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

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

1) Using it every night instead of 3-4x/week max. 2) Skipping SPF the next morning. 3) Layering it under another acid product the same night. 4) Applying on damp skin, which increases sting and uneven penetration. 5) Rubbing it in rather than patting, which increases friction irritation on already-exfoliated skin.

Overuse threshold: beyond 4 nights per week, continued use produces barrier damage — visible as tightness, flaking, and rebound oiliness — rather than faster pore-clearing results.

Usage math: at 2-3 drops per use and roughly 30 drops per ml, a 30ml bottle holds approximately 300-450 uses.

Lifespan at recommended dosage: used 3-4x/week, one bottle lasts roughly 5-7 months; at 2-3x overdosing (nightly use, which this description advises against), it would deplete in under 3 months while also damaging the barrier faster than it delivers results.

Reorder timing: begin reordering about 2 weeks before you estimate depletion, to allow for shipping time.

Pore congestion in Mauritius's heat often gets worse from over-cleansing, not dirt — this serum's job is to do the clearing chemically at night, gently, without you scrubbing at your skin during the day. It sits in the exfoliation lane of your PM routine, applied after cleansing and any toner, before moisturizer.

AM: 1) Gentle cleanse or rinse, 2) Hydrating toner (optional), 3) Niacinamide/soothing serum (optional), 4) Moisturizer, 5) SPF50+ PA++++, mandatory. PM (acid nights, 3-4x/week): 1) Double cleanse if wearing SPF/makeup, 2) Optional toner, 3) Zero Pore One-Day Serum — 2-3 drops, pressed in, wait 30-60s, 4) Moisturizer. PM (recovery nights): cleanse, hydrating toner, barrier-support moisturizer only, no actives.

If your skin is barrier-compromised right now (stinging on moisturizer, visible flaking): pause this serum entirely and use only gentle cleanser plus a barrier cream for 1-2 weeks before reintroducing at 1x/week. If you're in AC all day: seal this serum's hyaluronic-acid layers with a proper moisturizer every single time, since AC-dry air will otherwise pull moisture back out through the HA. If you're in your luteal phase and pores feel more congested than usual: keep to your planned frequency rather than adding extra nights — overuse compounds congestion via barrier stripping, it doesn't clear it faster.

Stock-true bundle — "Zero Pore Overnight Set": Zero Foam Cleanser + this serum + Zero Pore One-Day Cream + Zero Pore Moisture Sun Serum — a coherent same-family pore-care routine, all verified in stock.

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

The recommendations above are based on formulation synergy with Zero Pore One-Day Serum, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.

If a strong nightly acid isn't right for you yet, Medicube's own Zero Pore Serum 2.0 37ml (verified in stock) delivers pore-refining texture with a silicone-forward, no-free-acid formula — a genuinely gentler alternative with a different mechanism (visual pore-blurring rather than chemical exfoliation) at a lower irritation risk.

Choose the One-Day Serum over Zero Pore Serum 2.0 if you need real chemical exfoliation that clears congestion rather than just visually blurring it — the One-Day Serum actually dissolves what's inside the pore; the 2.0 serum optically diffuses light over the pore's surface without removing anything.

Upgrade if: your congestion doesn't respond to Serum 2.0's blurring effect after 4-6 weeks; your skin already tolerates AHA/BHA elsewhere; you don't have active eczema or a compromised barrier right now.

Don't upgrade yet if: your barrier currently stings on moisturizer; you can't commit to daily SPF; you're already running a retinoid or another strong acid; you're new to actives entirely — start with Serum 2.0 first.

If you match 2 or more upgrade triggers above, the One-Day Serum is worth choosing. If not, Zero Pore Serum 2.0 is sufficient and safer. Consistency beats complexity.

A real strength ladder exists within this family: Zero Pore Pad Mild (gentle PHA-only) → Zero Pore Serum 2.0 (no free acids, optical blur) or Zero Pore Pad 2.0 (4.5% Lactic + 0.45% Salicylic) → this serum (15.2% triple acid) → Zero Pore One-Day Peptide Serum (same acid base plus a peptide/firming layer, for users who've built tolerance and want an added anti-aging angle).

This product's PRIMARY function is: chemical exfoliation for pore congestion and surface texture. You do NOT need this if you already own another AHA/BHA/PHA leave-on exfoliant you're using consistently — finish that one first.

Inventory audit: check for an already-open acid serum or pad with the same primary function; with a 12-month PAO, buying a new bottle while an old one expires unused is waste.

Stacking assessment: against Zero Pore Pad 2.0 — No Benefit (same exfoliation mechanism, redundant if run concurrently). Against Zero Pore Serum 2.0 — Significant Benefit (different mechanism, chemical vs. optical). Against a Vitamin C serum — Marginal Benefit if run on alternating routines, but never combine them same-night per the brand's own instruction.

Quick verification tips: genuine Medicube packaging carries a QR code on the inner box that resolves to medicubeverify.com with a green checkmark; check for a clean, legible embossed batch code near the packaging seam; label print quality should be sharp with no spelling errors.

Medicube positions itself as a "medical beauty" brand pairing at-home devices (its AGE-R line) with companion topical actives. The Zero Pore family is its dedicated pore-and-sebum sub-line, running from very gentle pads to this genuinely high-strength overnight resurfacing serum — the brand tends to vary active concentrations sharply across products that share family branding, so checking each SKU's own numbers (as this description does) matters more than trusting the family name alone.

A Hwahae/WhatsInMyJar-style reviewer described it as effective enough to use "as a makeup primer" long-term, comparing the finish favorably to a well-known luxury silicone primer — a fan of the texture and consistency of use, skin type not specified.

A mixed reviewer reported using it for about a week without noticing a meaningful difference, describing it as "kinda sticky" and questioning the value at its price point relative to the effect they experienced — this is a genuinely short trial window for an exfoliant whose real results build over 4-6 weeks, so their experience may reflect timing as much as the product itself.

A critical reviewer argued the formula reads as "functionally a silicone primer with no active skin-improving ingredients," pointing to botanical extracts sitting low in the INCI — a fair observation about the botanicals specifically, though it understates that the brand's headline actives (the 15.2% acid complex and 2% Niacinamide) sit at genuinely high, not buried, INCI positions.

Common praise theme: fragrance-free, works well as a base layer under makeup for some users. Common complaint theme: sticky/tacky texture reported by multiple independent reviewers, at odds with the brand's own non-sticky claim.

Sustainability: glass components are recyclable through standard glass recycling where available in Mauritius; the dropper's rubber bulb and plastic parts should be separated first. Not a refillable format.

Can I use this every night? No — 3-4 nights per week maximum is the safe upper bound; nightly use risks barrier damage rather than faster results.

Will this actually shrink my pores? Not permanently — it clears what's congesting them so they look smaller, but the effect requires ongoing, moderate use to maintain.

Can I use it with Vitamin C? No, not in the same routine — the brand's own instructions say not to combine them; use Vitamin C in the morning and this serum at night instead.

Is it safe for sensitive skin? Not as a starting point — 15.2% total acid is an advanced-tier concentration; sensitive or reactive skin should start with a gentler Zero Pore family member first.

Why does it feel sticky for some people but not others? Individual skin chemistry and how much product is used both affect how the film-forming polymers feel on skin; using less product and waiting the full absorption time before the next layer reduces this for most users.

AHA

Alpha hydroxy acid — a water-soluble acid that loosens dead skin cell bonds at the surface.

BHA

Beta hydroxy acid (salicylic acid) — oil-soluble, so it can penetrate into oily pores specifically.

PHA

Polyhydroxy acid — a larger-molecule, gentler cousin of AHA that exfoliates more slowly and with less irritation.

Niacinamide

Vitamin B3 derivative that supports barrier function and helps regulate excess oil.

Barrier

The skin's outermost protective layer; when damaged it causes stinging, tightness, and flaking.

Purging

Temporary, accelerated surfacing of existing congestion caused by an active ingredient — resolves within weeks.

PAO

Period After Opening — how long a product stays safe/effective once opened, shown as a jar icon with a number.

Skin cycling

A rotation method that alternates active nights with recovery nights to reduce over-exfoliation risk.

Store Policies: For the most up-to-date information, please review our Shipping Policy and Refund Policy.

Best for: oily/combination skin with genuine pore congestion and texture concerns, already comfortable with AHA/BHA actives and a daily SPF habit. Not a beginner's first acid product.

Key benefits: a genuinely high, disclosed 15.2% acid complex with a large PHA fraction that's gentler than the percentage suggests; 2% Niacinamide as a real co-active; fragrance-free formula with no major FA-trigger esters identified.

Keep in mind: exact pH isn't disclosed, reviewer experience on texture (sticky vs. non-sticky) genuinely varies, and this is a PM-only, SPF-mandatory product — it doesn't fit a low-maintenance routine.

Assessment: Not Suitable. Although fragrance-free, the 15.2% combined AHA/BHA/PHA acid load is a strong exfoliant class generally contraindicated for skin undergoing cancer treatment, which is typically more fragile, slower to heal, and more prone to irritation.

A gentler barrier-support option, such as PDRN Pink Hyaluronic Moisturizing Cream, is a more appropriate category during active treatment.

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

Quick version: Week 1-2, introduce alone at 1x/week and monitor. Week 3-4, increase to 2-3x/week if stable. Week 5+, hold at 3-4x/week maximum — don't add another active yet. If irritation appears at any point, use the 72-Hour Barrier Reset above rather than pushing through.

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

AC/humidity swing interaction: this serum carries multiple hyaluronic acid forms as humectants. In prolonged air-conditioned environments, humectants can pull moisture from deeper skin layers rather than the (dry) surrounding air — always follow with a proper moisturizer to seal this in, not just after this serum but every single time you're in AC for extended periods.

Impact: Neutral-to-Supportive. The formula contains Lactobacillus Ferment Lysate, a POSTBIOTIC — beneficial metabolites from fermentation. You are not applying live bacteria; this ingredient supports skin conditioning rather than directly feeding or disrupting the resident microbiome.

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