ZEROID Intensive Hydrating Ampoule 30ml

Badges: 100% Genuine | FA-Safe | Pregnancy-Safe | Fragrance-Free | Halal-Friendly* | Vegan-Friendly*

If your skin feels oily by midday but also tight and uncomfortable right after cleansing, that is not "oily skin" fighting you — it is dehydrated skin overproducing sebum to compensate for water loss. This ampoule addresses the water side of that equation directly, which is usually the part people skip while chasing oil-control products.

Pros: extremely short, low-risk ingredient list; genuinely fragrance-free; layers under anything without pilling. Caveats: no barrier lipids of its own (must be sealed with a moisturizer or it evaporates back out), concentrations of its active ingredients are not brand-disclosed, and it does not treat acne, dark spots, or texture.

*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.

The "grimy" feeling in Mauritius heat is sebum and sweat doing their protective job, not dirt. Washing more than twice daily strips the acid mantle (target pH 4.5-5.5) and triggers compensatory sebum overproduction — the exact oiliness you were trying to fix.

This ampoule breaks the cycle from the water side: Sodium Hyaluronate and the peptide-urea complex support the skin's own Natural Moisturizing Factor, so skin stops reading "dehydrated" as an emergency and dials back the compensatory oil signal over time. It has no oil phase of its own, so pair it with a moisturizer to actually trap that water in.

Compatibility: Bedside-table compatible. No sink required. No wait time needed before the next step if you're crashing.

Minimum Viable Routine: This plus a moisturizer is a legitimate two-product routine on a low-energy night — it does the hydration job a 3-layer toner stack would, in one step.

Sensory Aversion: Watery and fast-absorbing with zero tack, so it works for anyone who avoids gel or sticky-feeling products when overstimulated.

Step 1: Use AM and/or PM, after toner and before moisturizer.

Step 2: 2-3 drops or roughly one dropper-pump for the face.

Step 3: Press into slightly damp skin with hands, wait 30-60 seconds, then seal with a moisturizer.

The One Rule: Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

1. Rinse with water or gentle cleanser.
2. Hydrating toner (optional).
3. ZEROID Intensive Hydrating Ampoule
4. Moisturizer
5. Sunscreen (SPF50+ PA++++)

In Mauritius morning humidity, this ampoule's Sodium Hyaluronate draws water from the humid air toward the skin surface rather than pulling from deeper layers — but only if you seal it with a moisturizer before the day's heat and AC dry it back out.

1. Oil cleanser or micellar water (if wearing SPF/makeup).
2. Water-based cleanser.
3. Toner (optional).
4. ZEROID Intensive Hydrating Ampoule
5. Treatment serum, if used (different lane only).
6. Moisturizer

Because this ampoule carries no active-ingredient conflicts, it sits comfortably before or after a retinoid or acid serum in the same routine — it does not need its own lane.

Technique: Press/pat into skin, do not rub — friction does nothing for a watery serum and just wastes product on your palms.

Required Skin State: Apply to slightly damp skin for best spread; toner beforehand is optional but helps this layer go further.

Wait Times: 30-60 seconds before your next layer is enough — this is a thin, fast-absorbing formula, not a thick serum that needs long dry-down.

Cotton Pad vs Hands: Hands deliver 100% of product. Cotton pads absorb approximately 30-40%. Use hands for this ampoule.

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 → 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 or applying makeup.

Amount defaults (unless brand-specific instructions override):
- Watery toner/essence: 5-8 drops per layer (or "coin-size puddle in palm")
- Serum/ampoule: 2-3 drops or 1 pump (face), add +1 drop for neck if used
- Eye product: ½ rice-grain per eye
- Gel moisturizer: 1-1.5 peas; Cream: 1-2 peas
- Occlusive seal: rice-grain to pea-size max
- Sunscreen: 2-finger rule for face; +1 finger for neck

Skin state rules: hydrators (toners/essences/HA) best on slightly damp skin; retinoids best on fully dry skin (wait 10 minutes after cleansing if sensitive); exfoliating acids on dry or lightly damp skin depending on irritation, keep to one lane. Hard cap rule: if the routine pills, stings, or feels heavy, reduce layers, not increase.

AM (maximum map):

• Rinse / Gentle Cleanse (optional) — 1-2 pumps, rinse, pat to slightly damp.
• pH-Prep / Balancing Toner (optional) — 5-8 drops, wait 10-20s.
• Hydrating Toner Layers (1-3, optional) — 5-8 drops per layer.
• Essence (optional) — 5-8 drops.
• Mist / Thermal Water (optional) — 1-2 sprays.
• Booster / Soothing Serum (optional) — 2-3 drops.
• Antioxidant Lane (choose ONE) — L-Ascorbic Acid (dry skin, wait 1-3 min) OR gentler antioxidant (30-60s).
• Pigment Support Lane (optional) — 2-3 drops; needs daily SPF to work.
• Hydration Serum Lane — this ampoule sits here, on slightly damp skin, 2-3 drops, wait 30-60s. Must be sealed with moisturizer, especially in AC.
• Oil-Control / Sebum-Regulating Lane (optional) — 2-3 drops.
• Peptides / Repair Lane (optional) — 2-3 drops.
• Eye Serum/Cream (optional) — ½ rice-grain per eye.
• Moisturizer — gel 1-1.5 peas / cream 1-2 peas, wait 1 minute before sunscreen.
• Optional Sealing Layer (only if dry/AC) — rice-grain to pea-size max.
• Sunscreen SPF50+ PA++++ (non-negotiable) — 2-finger rule, wait 10-15 minutes.
• Lip SPF (optional but ideal) — 1 swipe.

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

PM (maximum map):

• Micellar (optional pre-cleanse) — saturate cotton, gentle swipe.
• Oil Cleanser / Balm (if SPF/makeup) — massage dry 30-60s, emulsify, rinse.
• Water Cleanser (second cleanse) — 1-2 pumps.
• pH-Prep Toner (optional) — 5-8 drops.
• Hydrating Toner Layers (optional) — 5-8 drops per layer.
• Essence (optional) — 5-8 drops.
• Soothing / Barrier Serum (optional) — 2-3 drops.
• [Anchor Product — this ampoule] — 2-3 drops, wait 30-60s.
• Targeted Serum (optional, only if not conflicting) — 2-3 drops.
• Moisturizer — cream 1-2 peas, wait 1 minute.
• Sleeping Mask (optional) — thin layer.
• Occlusive Seal (optional) — rice-grain to pea-size max.
• Spot Treatment / Pimple Patch (as needed).
• Lip Sleeping Mask (optional) — thin swipe.

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 Tier: Water-thin, single-phase liquid.

Layering Rule: Apply after any toner, before serums with actives (Vitamin C, retinoids, acids), and always before moisturizer. It has no oil phase, so nothing about it interferes with penetration of a treatment layered after it.

Phase Compatibility: Water-phase only — no oil-phase or silicone-phase ingredients, so it does not create a barrier that would block a subsequent water-based serum.

Prerequisites: None — this is one of the lowest-risk products in a routine and can be a first step for someone new to actives.

Surface Dehydration: Sodium Hyaluronate binds water at the skin surface; the peptide-urea ingredient is positioned by the brand as supporting the skin's own Natural Moisturizing Factor production, though the exact mechanism and concentration are not brand-disclosed.

Tightness After Cleansing: A quick water-phase layer to soften that pulled feeling before moisturizer goes on.

What this product CANNOT do: It cannot exfoliate, brighten dark spots, treat active acne, or repair a damaged lipid barrier on its own — it has no oils, acids, or ceramides in its formula. Pair it with a barrier cream (like ZEROID's own Intensive Cream) for structural repair.

• ROUND LAB 1025 Dokdo Cleanser 150ml — a low-pH gentle cleanser that won't strip the hydration this ampoule adds back. (AM/PM.) Alternatives in stock: Beauty of Joseon Green Plum Refreshing Cleanser 100ml, SKIN1004 Madagascar Centella Ampoule Foam 125ml.
• ZEROID Intensive Cream 80ml — the barrier-lipid seal this ampoule needs to actually hold its hydration; same brand, same skin philosophy. (AM/PM.) Alternative: ETUDE SoonJung 2x Barrier Intensive Cream 60ml.
• SKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum 50ml — a watery sunscreen that layers over this ampoule without pilling. (AM.) Alternatives in stock: Anua Heartleaf Silky Moisture SunCream 50ml, Beauty of Joseon Relief Sun: Rice + Probiotics 50ml, SKIN1004 Madagascar Centella Air-Fit Suncream Light 50ml.
• celimax THE VITA-A Retinol Shot Tightening Serum 30ml — this ampoule can sit either side of it in a PM routine to soften the retinoid's dryness without diluting its effect. (PM.)

Pilling pairs: Low pilling risk given its water-thin, single-phase texture — the more common issue is applying too much sunscreen or heavy silicone product right after without letting this ampoule dry down for 30-60 seconds first.

Permeability: Water-Permeable (wudu-compatible).

This is a single-phase watery liquid with no film-forming polymers, silicones, or waxes — it absorbs into the skin surface and does not create a barrier to water reaching the skin during ablution.

Adilsons provides this assessment based on the product's physical properties. Rulings on wudu validity vary between scholars. Consult your own trusted Islamic authority.

MYTH: "A serum called an 'ampoule' must be more concentrated or more active than a regular serum."
REALITY: "Ampoule" in Korean skincare marketing is a texture/positioning term, not a regulatory concentration claim. This one is a 7-ingredient minimalist hydrator — the name doesn't imply clinical strength.

MYTH: "Hyaluronic acid alone is enough to fix dry skin."
REALITY: HA binds water but does not supply it or seal it in. Without adequate ambient humidity or a moisturizer on top, HA can pull water from deeper skin layers instead — this is why sealing this ampoule matters, especially in air conditioning.

In air-conditioned environments, the Sodium Hyaluronate in this ampoule can draw moisture FROM your deeper skin layers instead of from the dry AC air. Always seal this product with an occlusive moisturizer when you'll be in AC for extended periods.

Full INCI List: Water/Aqua, Butylene Glycol, 1,2-Hexanediol, Sodium Hyaluronate, [--- Estimated 1% Line ---] Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate, Glycerin, Magnesium Chloride.

Given the extremely short 7-ingredient list, this estimated-1%-line placement is a low-confidence approximation, not lab-confirmed data — sourced from WebSearch aggregation of INCIDecoder/SkinSort listings (direct site access was blocked this run).

*Clinical evidence for the peptide-urea ingredient's NMF-support mechanism is based on retailer/brand marketing descriptions, not a cited in-vitro or in-vivo study found this run.

Fragrance Status: Fragrance-Free. No essential oils, no synthetic parfum, no masking fragrances anywhere in the 7-item INCI.

Scent Description: No detectable scent expected from this ingredient list.

Intensity/Dissipation: 0 out of 5 — no fragrance-contributing ingredients present.

EU 26 Allergen Screen: None detected in declared INCI.

Alcohol Disclosure: Alcohol-Free. 1,2-Hexanediol is a diol used as a preservative booster/mild solvent, not a drying alcohol like ethanol or denatured alcohol.

Halal Status: Halal-Friendly*

Vegan Status: Vegan-Friendly*

Cruelty-Free Status: Brand-stated, uncertified*

Microplastic-Free: Yes — no film-forming polymers or synthetic microbeads detected in the declared INCI.

*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.

*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.

*Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit.

MFDS Classification: General Cosmetic. No evidence found that this specific SKU carries Korean MFDS Functional Cosmetic classification.

Evidence Confidence: Medium. ZEROID's parent company Neopharm is a well-documented, dermatology-channel Korean skincare manufacturer, but this specific SKU's ingredient claims are described only in brand/retailer marketing copy, not a published clinical study.

Fungal Acne Safety: FA-Safe. No fatty-acid esters, oils, or known Malassezia-feeding ingredients in the 7-item INCI.

Pilling Assessment: None to Low.

A single-phase watery liquid with no film-forming or thickening polymers rarely pills on its own. If pilling occurs, it is almost always caused by a heavier product layered on top before this one has dried down.

Mitigation: Wait 30-60 seconds before applying the next layer; apply to slightly damp, not soaking, skin.

Color Baseline: Clear to very faintly hazy liquid.

Storage: Keep out of direct sunlight; Mauritius bathroom humidity is not a major concern for this water-based, single-phase formula, but a cool, dry spot extends shelf life.

Spoilage Signs: Cloudiness that wasn't there originally, an off/sour smell, or visible particles. When in doubt, discard.

Patch Test: Apply a small amount to your inner forearm for 24h, then behind the ear for 24h, before full facial use.

72-Hour Barrier Reset: 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, breathing difficulty (seek emergency care).

Skipping the moisturizer after: HA-based ampoules without a sealing layer can leave skin feeling more dehydrated in dry air, not less.

Expecting active-ingredient results: This is a hydration layer, not a treatment for acne, pigmentation, or texture — don't judge it by a standard it was never built to meet.

Over-applying: More product does not mean more hydration once skin is saturated; 2-3 drops is enough for the whole face.

Volume: 30ml. Recommended amount per use: ~0.5-1ml (2-3 drops). Uses per container: approximately 30-45 applications.

At recommended dosage (once or twice daily): approximately 3-6 weeks depending on AM+PM vs. PM-only use. Using significantly more per application than needed will deplete the bottle faster without adding benefit past skin saturation.

Reorder in approximately 1-1.5 months if using twice daily. We recommend reordering 2 weeks before estimated depletion for shipping time.

A simple, low-risk hydration base for any routine, not a treatment step.

This ampoule sits at the thinnest rung of the viscosity ladder, right after toner and before anything with a texture heavier than a watery serum.

AM Routine:
1. ROUND LAB 1025 Dokdo Cleanser (1 pump)
2. ZEROID Intensive Hydrating Ampoule (2-3 drops, press in)
3. ZEROID Intensive Cream (1 pea, seal it in)
4. SKIN1004 Madagascar Centella Water-Fit Sun Serum (2-finger rule)

PM Routine:
1. Double cleanse if wearing SPF/makeup
2. ZEROID Intensive Hydrating Ampoule (2-3 drops)
3. celimax THE VITA-A Retinol Shot, if using (dry skin, wait 5 min) — different lane, no conflict
4. ZEROID Intensive Cream (1-1.5 peas, seal it in)

If your skin is dehydrated-oily (shiny by noon but tight after cleansing), use this ampoule under a gel-cream moisturizer instead of a heavy cream in the AM. If you're in AC all day, reapply a thin layer mid-afternoon and always seal it.

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

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

If you want a more actively soothing hydration serum rather than a pure minimalist HA formula, consider the SKIN1004 Madagascar Centella Ampoule 30ml. You trade the ultra-short ingredient list for Centella Asiatica extract's anti-redness benefits alongside similar hydration support — a reasonable swap if calming is your bigger priority than pure hydration.

Choose ZEROID Intensive Hydrating Ampoule over SKIN1004 Madagascar Centella Ampoule if you need the absolute lowest-risk ingredient list possible: it has 7 ingredients total against a longer, extract-driven formula, and carries no botanical extract that could itself be a sensitivity trigger for some users.

• Upgrade to THIS if you are testing a new routine on very reactive or newly-recovering skin and want to isolate variables.
• Upgrade to THIS if you specifically want pure hydration with no botanical extracts at all.
• Best placed as the water-hydration step right after toner, before any treatment serum.

Do NOT upgrade to THIS if:

• You want visible calming/redness benefit alongside hydration — the Centella alternative does more there.
• You already own a hydrating serum doing the same water-phase job (redundant purchase).

If you match 2 or more upgrade triggers above, THIS is worth choosing. If not, the alternative is sufficient and safer. Consistency beats complexity.

This product's PRIMARY function is: water-phase surface hydration via Sodium Hyaluronate. You do NOT need this if you already own a hydrating toner/essence/ampoule you're actively using and finishing. Finish your current product before purchasing a second.

Check your current shelf. Do you have an open hydrating serum with the same primary function? PAO on most Korean ampoules runs 6-12 months once opened — buying new while old expires is waste.

Stacking assessment: No Benefit if combined with another pure-HA serum (same mechanism). Marginal-to-Significant Benefit if combined with a Centella- or niacinamide-based serum (different, complementary pathway).

This product is sourced through authorized Korean distributors — primarily Craver Co., Ltd (South Korea), alongside other verified distribution partners. Craver is a major Korean beauty distributor and the parent company of SKIN1004, handling authorized distribution for multiple K-beauty brands. All products are shipped directly to Mauritius via verified channels.

Quick Verification Tips: Check for a batch code printed on the box and on the bottle itself — they should match. Genuine ZEROID retail boxes carry Neopharm's brand markings consistently across the line.

Brand: ZEROID. Parent Company: Neopharm Co., Ltd (South Korea, founded circa 2000 in Daejeon). Headquarters: South Korea. Philosophy: "Zero + Steroid" — non-steroidal, dermatology-channel skincare for compromised, reactive, or atopic-tendency skin.

ZEROID launched in 2002 originally for clinic and hospital use, built around Neopharm's MLE (Multi-Lamellar Emulsion) lipid technology. It is reported across independent brand-profile sources to be distributed through 4,000+ hospitals and clinics in Korea, positioning it closer to a dermatology-channel brand than a general cosmetics line — though this specific ampoule is one of the brand's simpler, non-emulsion formulas rather than an MLE product.

Community reviews for this specific product were not yet available in our research at the time of writing. A product listing exists on Hwahae (a Korean skincare review platform), but individual review text was not retrievable through the research tools available this run, and no dedicated Reddit thread (r/AsianBeauty, r/SkincareAddiction) was found for this exact 30ml SKU.

We will not invent quotes to fill this section — if you've used this product, we'd genuinely welcome hearing from you via WhatsApp so future customers have real feedback to read.

Please check local recycling guidelines for the glass/plastic bottle and dropper components separately.

Is this the same as a hyaluronic acid serum from another brand?
Functionally similar in category, but this specific formula is a 7-ingredient minimalist blend rather than a multi-molecular-weight HA complex — a simpler, lower-risk formula rather than a more "advanced" one.

Does "ampoule" mean it's stronger than a regular serum?
No. In Korean skincare, "ampoule" is a marketing/texture term, not a concentration guarantee — this one is intentionally minimalist.

Can I use this with retinol or Vitamin C?
Yes. It has no acids or actives of its own, so it does not conflict with anything — it can sit anywhere in the water-phase part of your routine.

Is it fungal-acne safe?
Yes — no oils, fatty-acid esters, or other known Malassezia-feeding ingredients are present in its short INCI list.

Will it feel sticky in Mauritius humidity?
No — it is water-thin and absorbs with no detectable residue, unlike some thicker gel-ampoules.

Sodium Hyaluronate

The salt form of hyaluronic acid, used in skincare because it penetrates and binds water more readily than hyaluronic acid itself.

Natural Moisturizing Factor (NMF)

A blend of amino acids, urea, and salts your skin naturally produces to hold onto water in the outer skin layer.

Single-Phase Formula

A product with no separate oil layer — entirely water-based, which is why it absorbs without any greasy residue.

Acid Mantle

The slightly acidic protective film on the skin's surface, important for keeping bacteria out and moisture in.

Fungal Acne (Malassezia Folliculitis)

Small, uniform, itchy bumps caused by yeast overgrowth, which feeds on certain fatty-acid esters and oils in skincare — not present in this formula.

PAO (Period After Opening)

The number of months a product stays safe/effective to use once opened, shown as a small jar icon with a number on the packaging.

Best For: Anyone who wants a simple, low-risk hydration layer — dry, dehydrated, oily-dehydrated, or reactive skin new to actives.

Key Benefits: An unusually short, transparent 7-ingredient formula; genuinely fragrance-free; fast-absorbing with zero residue in humidity; layers safely with anything.

Keep In Mind: It has no barrier lipids or oils of its own and must be sealed with a moisturizer, its active concentrations are not brand-disclosed, and it will not treat acne, pigmentation, or texture concerns.

Assessment: Suitable.

Fragrance-free with a minimal, low-irritant-potential 7-ingredient formula and no retinoids, acids, or essential oils — a reasonable hydration option for treatment-sensitized skin.

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

AC and Humidity Swing Interaction: This is a humectant-heavy formula (Sodium Hyaluronate, Glycerin, Butylene Glycol). In humid outdoor Mauritius air it pulls moisture toward the skin; in prolonged air-conditioned indoor time, it can pull moisture from your deeper skin layers instead if left unsealed. Always follow it with a moisturizer before long AC exposure.
