IUNIK Beta Glucan Barrier Ampoule Cleanser 120ml

100% Genuine (Adilsons policy) • Fragrance-Free • Likely FA-Safe for a rinse-off use pattern

If your face feels tight and squeaky ten minutes after washing, that's not "clean" — it's a stripped acid mantle, and this formula is built specifically to avoid causing that.

Pros: low-lather amino-acid base, barrier lipids built into a cleanser (uncommon), fragrance-free, works as either a first or second cleanse. Caveats: the 4,000ppb Beta-Glucan figure is far lower than IUNIK's leave-on Beta-Glucan serum, so don't expect serum-level hydration from a rinse-off step; no independent third-party reviews were found for this exact, recently-listed SKU.

In Mauritius heat, the oily film on your skin by midday is mostly sebum and sweat doing their job, not dirt — but it feels grimy, so the instinct is to wash harder or more often. Washing more than twice daily strips the skin's acid mantle (target pH 4.5-5.5), and the skin responds by overproducing sebum to compensate, which is the exact oiliness the extra washing was meant to fix.

This formula's amino-acid surfactant blend (Potassium Cocoyl Glycinate, Disodium Cocoamphodiacetate, Sodium Cocoyl Isethionate) foams less aggressively than sulfate (SLS/SLES) cleansers, and the built-in Ceramide NP and Hyaluronic Acid are designed to replace some of what a stronger cleanser would remove, in the same step.

Step 1 (When): AM and PM, or PM only as your second cleanse after an oil cleanser on makeup/sunscreen days. Step 2 (How much): a generous pump into wet or dry hands (the brand's own instructions describe roughly 10 pumps for a full massage). Step 3 (How): massage in circular motion 30-60 seconds, then rinse with lukewarm water.

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. Beta Glucan Barrier Ampoule Cleanser (rinse off, pat skin to slightly damp) → 2. Toner → 3. Serum → 4. Moisturizer → 5. Sunscreen SPF50+ PA++++. In Mauritius's humid mornings, applying your toner/serum to slightly damp (not bone-dry) skin lets humectants like glycerin and hyaluronic acid draw ambient moisture inward rather than pulling it from deeper skin layers.

No AM restriction and no mandatory-SPF exception applies to this step itself, but sunscreen later in the routine is non-negotiable regardless of which cleanser you use.

1. Oil/balm cleanser (if wearing makeup or sunscreen) → 2. Beta Glucan Barrier Ampoule Cleanser (second cleanse) → 3. Toner → 4. Treatment serum → 5. Moisturizer. On bare-skin days with no sunscreen, this cleanser alone is sufficient as a single-step PM cleanse.

Because this is a passive, non-active cleanser, it has no skin-cycling lane assignment — it sits underneath whatever active (retinoid/acid/Vitamin C) lane you run that night.

*Pump-to-ml estimate; the brand does not disclose exact ml-per-pump for this dispenser.

Technique: massage in circular motion for the full 60 seconds the brand recommends — this gives the surfactants adequate contact time to lift sebum before rinsing. Apply to either dry skin (for makeup/sunscreen dissolving, per the brand's own two-step instructions) or pre-rinsed damp skin for a standard lather-and-rinse cleanse.

Hands deliver 100% of product; a cotton pad is not appropriate for a rinse-off foaming cleanser.

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 runs thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults: watery layers 10-20s, serum layers 30-60s, 10-15 minutes before sunscreen if going outdoors. Amount defaults: toner/essence 5-8 drops per layer, serum 2-3 drops or 1 pump, eye product ½ rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, sunscreen the 2-finger rule for the face. Hydrators go on slightly damp skin; retinoids on fully dry skin. If the routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack: Rinse/Gentle Cleanse (this product, optional) → pH-Prep Toner (optional) → Hydrating Toner Layers (optional) → Essence (optional) → Mist (optional) → Booster/Soothing Serum (optional) → Antioxidant Lane (choose one) → Pigment Support Lane (choose one) → Hydration Serum Lane (optional) → Oil-Control Lane (choose one) → Peptide/Repair Lane (optional) → Eye Serum/Cream (optional) → Moisturizer → Optional Sealing Layer → Sunscreen SPF50+ PA++++ (non-negotiable) → Lip SPF (optional). In AM, prioritize comfort and SPF adherence over stacking; in high humidity, fewer layers often perform better.

PM Maximum Stack: Micellar pre-cleanse (optional) → Oil Cleanser/Balm (if wearing SPF/makeup) → Water Cleanser (this product, second cleanse) → pH-Prep Toner (optional) → Hydrating Toner Layers (optional) → Essence (optional) → Soothing/Barrier Serum (optional) → Anchor treatment product → Targeted Serum (optional, only if non-conflicting) → Moisturizer → Sleeping Mask (optional) → Occlusive Seal (optional) → Spot Treatment (as needed) → Lip Sleeping Mask (optional). Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C 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, rinse-off foaming liquid — the first rung of any routine, used and rinsed away before any leave-on layering begins. It has no phase-compatibility implications for later steps since nothing from it remains on the skin.

Barrier stripping from over-cleansing: the amino-acid base and built-in ceramide/lecithin blend are designed to cleanse without disrupting the lipid bilayer as much as harsher surfactants. Secondary benefit: removes light makeup and sunscreen as a single-step cleanse on low-makeup days.

What this product cannot do: it cannot deep-clean heavy, waterproof makeup or SPF alone as reliably as a dedicated oil/balm first cleanse — pair it with one on those days. It also cannot treat acne, hyperpigmentation, or fine lines; it is a cleanser, not a leave-on treatment.

Toner: primary — IUNIK Tea Tree Relief Toner 200ml (same-brand pH-follow-up). Alternatives: Anua Peach 77% Niacin Essence Toner, JUMISO All Day Vitamin Glow Boost Facial Toner, APLB Glutathione Niacinamide Facial Toner (only 1 unit left — check stock before ordering).

Moisturizer: primary — IUNIK Beta Glucan Daily Moisture Cream 60ml. Alternatives: IUNIK Centella Calming Gel Cream 60ml, Anua Birch Moisture Boosting Cream, IUNIK Beta Glucan 3X Barrier Cream (only 2 units left).

First-cleanse oil partner (makeup/SPF days): primary — IUNIK Calendula Complete Cleansing Oil. Alternatives: IUNIK Centella Green Fresh Cleansing Oil, COSRX Low pH Niacinamide Micellar Cleansing Water, Beauty of Joseon Green Plum Refreshing Cleanser.

Pilling: as a rinse-off product, this cleanser has no pilling interactions with leave-on layers.

Mauritius tap water hardness varies by region; hard water can leave a calcium-stearate film after cleansing that causes tightness even with a gentle cleanser. Following with a pH-adjusting toner (like the Tea Tree Relief Toner pairing above) helps counteract this residue.

Full INCI: Water, Potassium Cocoyl Glycinate, Glycerin, Disodium Cocoamphodiacetate, Acrylates Copolymer, Potassium Cocoate, Potassium Palm Kernelate, 1,2-Hexanediol, Sodium Cocoyl Alaninate, Sodium Chloride, Caprylyl Glycol, Coco-Glucoside, Sodium Cocoyl Isethionate, Sodium Phytate, Titanium Dioxide (CI 77891), [--- Estimated 1% Line ---] Butylene Glycol, Quillaja Saponaria Bark Extract, Citric Acid, Cynanchum Atratum Extract, Beta-Glucan, Althaea Rosea Flower Extract, Ethylhexylglycerin, Phytosterols, Polyglutamic Acid, Caprylic/Capric Triglyceride, Hydrogenated Lecithin, Ceramide NP, Hyaluronic Acid, Phosphatidylcholine, Glycine, Glutamic Acid, Serine, Alanine, Lysine, Arginine, Proline, Threonine.

*The brand's "84% skin-active ingredients" and "Dermatologist Tested" claims are brand marketing copy; no independent breakdown, sample size, or testing protocol has been disclosed.

Preservative system: 1,2-Hexanediol and Caprylyl Glycol function as the primary preservative/antimicrobial system — both are common, well-tolerated multifunctional preservatives rather than traditional parabens.

Fragrance-Free — no Parfum/Fragrance entry in the declared INCI. No EU26-listed fragrance allergen detected. Alcohol-Free — no Alcohol/Alcohol Denat./SD Alcohol entry.

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. Whether IUNIK sells through Mainland China retail channels (which can require post-market animal testing) has not been independently confirmed.

Microplastic-Free: Yes — Acrylates Copolymer here is a rinse-off viscosity modifier, not a solid particulate microplastic.

MFDS Classification: General Cosmetic — this formula contains no functional-cosmetic-registrable active at a disclosed clinical concentration. "Functional" cosmetics in Korea undergo additional government testing for specific claims (whitening, wrinkle-improvement, UV protection); nothing here has been confirmed as carrying that registration.

Evidence confidence: Medium for the amino-acid-cleanser mechanism (well-established surfactant chemistry); Low-Marketing-Only* for "84% skin-active ingredients" and "Dermatologist Tested," which carry no disclosed methodology.

Assessment: None — as a rinse-off product, nothing remains on skin to interact with subsequent leave-on layers.

Fresh product should be a light, near-colorless-to-translucent gel; any strong color shift or separation signals spoilage. Store away from direct bathroom-window sunlight and away from prolonged high heat — Mauritius bathroom humidity is generally fine for a rinse-off product, but a consistently hot shelf can degrade the surfactant/preservative system faster than the labeled shelf life assumes. Discard if the scent turns sour or rancid, or if texture separates and won't remix.

Patch test on the inner forearm for 24 hours, then behind the ear for 24 hours, before full facial use — standard practice even for gentle cleansers, since individual sensitivities vary. If you notice hives, swelling, blistering, persistent burning, or breathing difficulty, stop immediately and seek care; these are not "purging."

1) Using it as the only step on heavy-makeup days — it's a second cleanse, not a makeup remover. 2) Over-cleansing (3+ times daily) even with a gentle formula — frequency itself can strip the barrier regardless of surfactant mildness. 3) Skipping the follow-up toner in hard-water areas, leaving mineral residue on skin. 4) Rubbing rather than massaging gently, which increases friction-related irritation. 5) Assuming "ampoule" in the name means leave-on strength hydration — it's a rinse-off dose of Beta-Glucan, far below the brand's leave-on serum concentration.

At roughly 4-6 pumps per full-face cleanse used once or twice daily, a 120ml bottle typically lasts 6-10 weeks for once-daily use, or roughly half that for twice-daily use. Using more product than needed per wash does not improve cleansing — it simply shortens how long the bottle lasts. Reorder about two weeks before you expect to run out, to allow for delivery time.

This cleanser is the reset step underneath whatever active-ingredient routine you run — it doesn't compete with your serums, it prepares skin for them. AM: cleanse → toner → serum → moisturizer → SPF. PM: (oil cleanse if wearing makeup/SPF) → this cleanser → toner → treatment → moisturizer.

If your skin currently stings when you cleanse, the previous cleanser was likely too stripping — switching to this amino-acid formula and pairing it with the Tea Tree Relief Toner (both IUNIK, both barrier-focused) is a reasonable reset combination. If you're in AC most of the day, seal your post-cleanse moisturizer with an occlusive at night to counter the extra transepidermal water loss AC causes.

Stock-true bundle: this cleanser + IUNIK Tea Tree Relief Toner + IUNIK Beta Glucan Daily Moisture Cream forms a same-brand, barrier-first three-step routine.

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

The recommendations above are based on formulation synergy with this cleanser, 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 slightly higher-foam, more traditional bubble-cleanse feel, IUNIK Centella Bubble Cleansing Foam (69% Centella Asiatica Leaf Water base) is a same-brand alternative with a more classic foaming texture — the trade-off is a slightly higher-lather surfactant profile versus this cleanser's especially low-strip amino-acid base.

Choose Beta Glucan Barrier Ampoule Cleanser over the Centella Bubble Cleansing Foam if you need the gentlest possible daily cleanse: lower lather density and a built-in ceramide/lecithin blend give it an edge for compromised-barrier or very dry-leaning skin.

If your skin currently feels tight after cleansing, this formula's lower-strip surfactant blend is the better daily default. If you have very oily skin in peak humidity and want a slightly stronger clean feeling, the Bubble Cleansing Foam may suit you better on high-sebum days.

Don't switch if your current cleanser already leaves skin comfortable — there's no benefit to changing a cleanser that isn't causing a problem.

If you match the barrier-compromised or over-cleansed profile above, this is worth choosing. If not, either gentle cleanser in the catalog is sufficient. Consistency beats complexity.

This product's PRIMARY function is: gentle daily cleansing with barrier-supporting lipids. You do NOT need this if you already own a fragrance-free, amino-acid-based facial cleanser that isn't causing tightness or irritation — finish that one first. Two open cleansers age on the shelf just as any other skincare does; there is no stacking benefit to running two cleansers in the same slot.

IUNIK positions itself as an online-first, ingredient-led Korean skincare brand built around named hero-ingredient product lines rather than one shared active across the whole catalog. This Beta-Glucan Barrier line extends that hero ingredient into a cleanser format, applying the brand's barrier-support philosophy to the very first step of a routine rather than only its serums and creams.

Community reviews for this specific product were not yet available in our research at the time of writing — this is a recently listed SKU on Adilsons (added 2026-09-12). Broader reviews of IUNIK's Beta-Glucan line (the serum and sunscreen) describe good tolerance for sensitive and dehydrated skin, but we do not extend those reviews to this specific cleanser as if they were reviews of it.

Is this a first or second cleanser? It works as either — dry-skin application for makeup dissolving, or a standard second cleanse on pre-wet skin.

Will the low Beta-Glucan concentration still do anything? Its role here is supportive (gentle, non-stripping cleansing) rather than a leave-on hydration treatment — for that, IUNIK's Beta Glucan Power Moisture Serum uses a much higher, brand-stated concentration.

Is it fragrance-free? Yes, per the declared INCI.

Can teenagers use it? Yes — it carries no clinical-strength actives and is a gentle daily cleanser suitable for most ages.

Does it remove waterproof sunscreen fully on its own? Not reliably — pair it with an oil or balm first cleanse on heavy-SPF days.

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

Best for: anyone whose current cleanser leaves skin feeling tight, especially sensitive, dehydrated, or barrier-compromised skin types looking for a fragrance-free daily cleanse. Key benefits: low-strip amino-acid surfactant base, built-in ceramide/lecithin barrier support, fragrance-free, works as first or second cleanse. Keep in mind: its Beta-Glucan concentration is a rinse-off dose, not leave-on-serum strength; no independent third-party reviews exist yet for this recently-listed SKU; it will not fully remove heavy waterproof makeup on its own.
