SKIN1004 is a Korean serum/ampoule job candidate for Bioderma Sensibio Defensive Serum. It is not a formula dupe.
Bioderma Sensibio Defensive Serum is a 30 ml leave-on serum positioned by Bioderma for sensitive or sensitized skin. SKIN1004 Probio-Cica Intensive Ampoule is a Korean fermented-centella and ceramide ampoule. A post-toner hydration and soothing step can overlap; the ingredient systems, formats, market versions and product claims do not.
What Bioderma Sensibio Defensive Serum actually is
| Product surface used | Bioderma Sensibio Defensive Serum, the Japan-market official listing |
|---|---|
| Size and price checked | 30 ml / ¥4,609 on Bioderma Japan’s official shop |
| Format and directions | Leave-on serum; 3–4 drops after toner, morning and evening |
| Published formula signals | Glycerin, C15–19 alkane, squalane, carnosine, tocopherol, red-sage extract, rhamnose, hydrolyzed hyaluronic acid and palmitoyl tetrapeptide-10 |
| Brand positioning | Bioderma describes a sensitive/sensitized-skin serum using its Defensive Technology and D.A.F. formulation |
The official Japanese page publishes the product’s ingredient list, 30 ml size, price and after-toner directions. It also says that its testing and product statements do not mean every person will avoid irritation or comedones. Treat those as Bioderma’s market-specific claims, not as a guarantee.
The serum is a lighter leave-on step, not a cream or balm. If the shopping request is really for a rich last-step moisturizer, an ampoule comparison may solve the wrong problem.

Korean candidate: SKIN1004 Probio-Cica Intensive Ampoule
| Product | SKIN1004 Madagascar Centella Probio-Cica Intensive Ampoule |
|---|---|
| Official product surface | Barrier Supporting Soothing Ampoule; the global page lists 30 ml, 50 ml and 95 ml capacities |
| Published formula signals | Fermented Centella, Centella asiatica, madecassic acid, asiaticoside, asiatic acid and ceramide NP |
| Availability snapshot | The official global page showed a sold-out sale state when checked; a YesStyle 50 ml page showed in-stock availability in a Poland locale |
| Format boundary | Ampoule/serum layer, not a toner, cream or prescribed product |
SKIN1004 is the clearest Korean candidate when the requested replacement is a leave-on ampoule for a hydration or soothing step. Its published key ingredients are a fermented-centella and ceramide story, not Bioderma’s red-sage, carnosine, D.A.F. and peptide system.
The official and retailer pages show different markets, currencies and stock states. Check the exact 50 ml variant, current package and seller before buying; do not turn a locale-specific availability snapshot into a universal price or stock claim.

Is this a cheaper Korean alternative?
That is the shopping question behind this comparison, but it cannot be answered with one universal saving number. The checked Bioderma listing is 30 ml at ¥4,609 on a Japan-market official shop; the SKIN1004 candidate is sold in different 30 ml, 50 ml and 95 ml variants, and the retailer snapshot is a different locale. Compare the current market, currency, size, seller and stock before calling it cheaper. The useful answer is a Korean ampoule to investigate for the same broad leave-on step, not a guaranteed cheaper or equivalent replacement.
Why this replacement question is worth testing
A public r/koreanskincare question asks for a Korean dupe or alternative to Bioderma Defensive Serum. A reply names the SKIN1004 Probio-Cica ampoule, and the original poster later describes the Bioderma as expensive for its small amount. That is one high-intent conversation, not search volume, sales or proof that the products perform alike.
- Public Bioderma alternative question: exact product name, Korean-alternative language and a named SKIN1004 candidate.
- Bioderma’s official Japan listing: current product size, price, directions and ingredient context.
- SKIN1004’s official listing: ampoule format, capacities and published key ingredients.
Formula match or job match?
Formula match: no. Bioderma publishes a humectant/emollient serum with carnosine, tocopherol, red-sage extract, rhamnose, hydrolyzed hyaluronic acid and palmitoyl tetrapeptide-10. SKIN1004 publishes fermented Centella, Centella compounds and ceramide NP as key signals. No equal percentages, delivery system, texture, tolerance or head-to-head outcome has been established.
Conditional leave-on job match: yes. Someone comparing a post-toner hydration or soothing layer can evaluate both products. That inference does not mean SKIN1004 replaces every Bioderma use, every market label or any clinician’s recommendation.
Side by side
| Bioderma Sensibio Defensive | SKIN1004 Probio-Cica Intensive | |
|---|---|---|
| Broad job | Leave-on serum after toner in Bioderma’s sensitive-skin positioning | Korean leave-on ampoule for the brand’s soothing/barrier-support positioning |
| Published formula signal | Carnosine, red-sage extract, squalane, hydrolyzed hyaluronic acid and peptide | Fermented Centella, Centella compounds and ceramide NP |
| Variant snapshot | 30 ml / ¥4,609 on Bioderma Japan | 50 ml retailer page; market-specific price and stock |
| What it is not | Not proof that every serum with a sensitive-skin brief has the same formula | Not a Bioderma formula, medical product or treatment substitute |
Choose by the reason you are switching
- Want Bioderma’s exact 30 ml serum and after-toner directions? Check the current market listing and package for Sensibio Defensive Serum.
- Want a Korean ampoule with fermented Centella and ceramide NP? SKIN1004 is the candidate to investigate, subject to current variant and stock checks.
- Want a formula dupe? Stop here. The published ingredient systems differ, and ingredient presence does not establish concentration, delivery or outcome.
- Shopping for acne, rosacea, eczema, persistent irritation or a treatment? This page compares cosmetic products and brand positioning. It is not a diagnosis or treatment plan; ask a qualified clinician for health concerns.
Related serum and barrier-care comparisons
Keep the routine step and formula claim separate:
- Cicaplast Baume B5+ vs Purito — a balm and cream comparison with a different label boundary.
- Laneige Cream Skin vs AESTURA — a milky hydration layer versus a Korean essence-toner format.
- SK-II Facial Treatment Essence alternatives — first-essence job overlap with different ferment systems.
- Clinique Moisture Surge vs Isntree — a lighter gel-moisturizer job with different product formats.
What this page is not saying
We are not saying SKIN1004 contains Bioderma’s formula, has the same texture, delivers the same result, is non-comedogenic for every person, or treats a skin condition. We are saying that a Korean ampoule can be investigated for a similar leave-on hydration or soothing step while the published formulas, instructions, variants, prices and stock remain separate.
