IUNIK Beta Glucan and SKIN1004 Probio-Cica overlap on hydration, but their current formula briefs answer different shopping questions.
A recent public question asks which one to choose between IUNIK Beta Glucan Power Moisture Serum and SKIN1004 Probio-Cica Intensive Ampoule. The thread compares hydration, texture and barrier-care preferences, and the author later says they chose SKIN1004. The current official pages support a leave-on hydration comparison; they do not establish a universal winner, a treatment result or a formula match.
Why this exact pair is worth answering
The public r/koreanskincare question asks readers to choose between the two named products, describes a dry-to-combination and dehydrated shopping context, and mentions a separate barrier-cream decision. The post showed 5 upvotes and 21 comments at the check. Visible replies compare the beta-glucan serum as moisture-focused with SKIN1004 as a broader ampoule choice, while other replies say both can feel useful. The author later says they bought Probio-Cica and liked it. These are query and candidate-selection signals only. They are not search volume, representative preference, product testing, medical evidence or proof that either product works the same way for another person.
What IUNIK Beta Glucan Power Moisture Serum publishes
| Product | Beta Glucan Power Moisture Serum, 50ml |
|---|---|
| Routine job | Leave-on hydration serum for a moisture-focused layer |
| Published texture cue | The official page describes a silky gel-type texture that absorbs quickly without stickiness |
| Published formula signals | Mushroom-derived Beta-Glucan and a minimalist formula described as using 10 essential ingredients |
| Label wording | The current page describes the formula as fungal-acne-safe and suitable for sensitive or reactive skin; these are brand claims, not a medical or universal suitability finding |
| Price and stock context | The official page displayed US$18.90 sale / US$21.00 regular for 50ml and an Add to cart control at the check; this is a dated storefront snapshot |
The current IUNIK page calls out Beta-Glucan but did not show a concentration in the visible product summary. That matters because the public thread includes comments about a reformulation. The current page alone cannot reconstruct an earlier formula or prove that the present product matches a historical version.
What SKIN1004 Probio-Cica Intensive Ampoule publishes
| Product | Probio-Cica Intensive Ampoule; 50ml selected variant, with 95ml and 30ml options also shown |
|---|---|
| Routine job | Leave-on soothing and barrier-support ampoule positioned for dry, normal and combination skin |
| Published texture cue | The official page says it absorbs easily and leaves a silky, radiant finish without residue or stickiness |
| Published formula signals | Fermented Centella, Centella Asiatica, madecassic acid, asiaticoside, asiatic acid and Ceramide NP |
| Formula system cue | The page describes a ceramide, phytosterol and fatty-acid “3:1:1” system; this is the brand’s product description, not proof of equivalent performance elsewhere |
| Price and stock context | The official page displayed US$18.70 and Add to Bag, while its 50ml, 95ml and 30ml labels also said sold out or unavailable; treat availability as unresolved |
SKIN1004’s current page presents a fermented-Centella-and-ceramide barrier-support story. That can be a useful reason to choose it for this public question, but it does not make the product a beta-glucan formula or establish a universal “better” result.

Formula match, or same hydration job?
Formula match: no. IUNIK’s visible current page centers a minimalist beta-glucan gel and does not expose a concentration in the product summary. SKIN1004 exposes fermented Centella, TECA-related signals, Ceramide NP and a lipid-system description. Those are different published formula stories. A shared hydration goal, a community comparison or the presence of one soothing ingredient does not establish matching concentrations, texture or performance.
Job match: plausible. Both can sit in a leave-on hydration routine. IUNIK is the clearer candidate when the brief is a short ingredient list and quick, non-sticky gel feel. SKIN1004 is the clearer candidate when the brief is fermented Centella, ceramide and a soothing/barrier-support ampoule. The current market controls are dated snapshots and should be rechecked.
Side by side
| IUNIK Beta Glucan Power Moisture | SKIN1004 Probio-Cica Intensive | |
|---|---|---|
| Broad job | Leave-on moisture serum | Leave-on soothing/barrier-support ampoule |
| Texture cue | Silky gel, quick absorption and no-stickiness wording | Silky, radiant finish without residue or stickiness wording |
| Formula cue | Mushroom-derived Beta-Glucan, 10 essential ingredients described | Fermented Centella, TECA signals, Ceramide NP and a 3:1:1 lipid-system description |
| Size cue | 50ml | 50ml selected; 95ml and 30ml also shown |
| Checked price context | US$18.90 sale / US$21.00 regular | US$18.70 displayed |
| Availability cue | Add to cart shown | Add to Bag shown with unavailable labels on the displayed variants |
| Verdict here | Plausible same-job candidates; different current formula briefs, variant states and no universal winner. | |
Choose by the reason you are switching
- You want a simple hydration layer: IUNIK’s current page emphasizes Beta-Glucan, 10 essential ingredients and a quick, non-sticky gel texture. Check the current full ingredient list when a historical formula matters.
- You want fermented Centella and ceramide signals: SKIN1004’s page makes those the center of its Probio-Cica brief. That is a different formula direction from IUNIK’s beta-glucan-first page.
- You care about sticky feel: both official pages use low-stickiness or no-residue language. That is a useful screening cue, not proof that both feel identical on every person.
- You are comparing the reformulated IUNIK discussion: the public comments describe user perceptions of an earlier and current product, while the current official page supplies only the current product facts. Do not infer a historical concentration from the thread.
- You want an exact size or current stock: both pages have market-specific variant and purchase-state caveats. Recheck the selected SKU, seller, shipping and total cost at purchase.
- You are managing acne, rosacea, eczema, dermatitis or persistent irritation: this page compares cosmetic product information and does not diagnose or treat a condition. Ask a qualified clinician for health concerns.
