The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation) Korean alternative? S.NATURE Aqua Squalane Serum compared.
If you mean The Ordinary's original Hyaluronic Acid 2% + B5—not the separate version with Ceramides—S.NATURE Aqua Squalane Serum is a plausible Korean product to investigate for the same broad hydration-serum step. The formulas, sizes, markets and evidence are different.
What The Ordinary Original Formulation is
| Exact product | Hyaluronic Acid 2% + B5 (Original Formulation) |
|---|---|
| Format and size | Water-based serum, 30 ml on the cited US product page |
| Published formula signals | Four forms of hyaluronic acid plus pro-vitamin B5; the cited INCI also lists humectant and film-forming signals |
| Version boundary | The Ordinary also sells a separate Hyaluronic Acid 2% + B5 with Ceramides formula. That is not the product compared here. |
The official Original Formulation page describes a water-based serum with four types of hyaluronic acid at different molecular weights and pro-vitamin B5. Its published ingredient list includes sodium hyaluronate, sodium hyaluronate crosspolymer, panthenol and other humectant-related ingredients. The brand notes that ingredient lists can vary by time and region, so the package you receive remains the final check.
The “2%” name is a product-level claim, not permission to assume that every listed hyaluronic-acid form is present at the same concentration or that another serum with a similar ingredient family will feel or perform identically.

Candidate: S.NATURE Aqua Squalane Serum 50 ml
| Exact product | 아쿠아 스쿠알란 세럼 / Aqua Squalane Serum, 50 ml |
|---|---|
| Price snapshot | ₩21,000 on the official Korean product page when checked 31 August 2026; currency, promotions, shipping and duties move |
| Published formula signals | The product information surfaces show hyaluronic-acid, panthenol, squalane and botanical/conditioning signals; no squalane concentration is imported into this comparison |
| Variant boundary | The brand has separate 70 ml and 100 ml product surfaces. This page compares the 50 ml Korean SKU only. |
S.NATURE's official Korean page identifies the 50 ml Aqua Squalane Serum and its current product-page price snapshot. Its product information image and text-readable retailer surfaces provide a different ingredient story from The Ordinary: squalane appears alongside hydration and conditioning signals. That is enough to investigate a broad serum-step overlap, not enough to call the product a copy.
Do not transfer the 150,000 ppm squalane figure from the S.NATURE Aqua Squalane Moisturizing Cream comparison elsewhere on this site to this serum. The cream and serum are separate SKUs. This page intentionally leaves the serum's squalane concentration unclaimed.

Do not silently substitute the Ceramides version
The Ordinary's current “with Ceramides” page is a separate second-generation product surface. It describes five hyaluronic-acid forms, added ceramides and a lighter texture direction. If a shopper means that version, the exact-pair question changes. The product name alone is not precise enough; lock the package, market and current label before comparing.
Why this replacement question is worth testing
A February 2026 public Reddit question asks for a Korean alternative to The Ordinary Hyaluronic Acid 2%. One commenter names S.NATURE Aqua Squalane Serum. That is useful evidence that the replacement question exists in public conversation and that this exact pair can be explained. It is not search-volume, sales, efficacy or formula-equivalence evidence, and one comment cannot establish a general preference.

Formula match or job match?
Formula match: no. The Ordinary publishes a four-form hyaluronic-acid and B5 system in a 30 ml water-based serum. S.NATURE publishes a separate 50 ml serum with squalane and its own hydration/conditioning signals. Shared hydration language does not establish the same INCI, concentration, texture, finish or result.
Broad hydration-serum job match: plausible. Both are leave-on serums that can be investigated at a hydration layer in a routine. That is a narrower and more honest claim than “dupe.” We found no controlled same-day test establishing identical slip, tack, layering, pilling, glow, wear or skin response.
Side by side
| The Ordinary Original Formulation | S.NATURE Aqua Squalane Serum | |
|---|---|---|
| Broad routine job | Water-based hydration serum | Serum-format hydration step to investigate |
| Checked size and price | 30 ml; current US page price can move by market | 50 ml; ₩21,000 Korean page snapshot on 31 August 2026 |
| Published formula signals | Four HA forms, pro-vitamin B5 and other listed humectant/film-forming signals | Squalane, panthenol, HA and conditioning/botanical signals on the cited product surfaces |
| Version check | Original Formulation; separate “with Ceramides” page is excluded | 50 ml serum; separate 70 ml and 100 ml surfaces are excluded |
| Verdict | Original product and current published label | Possible Korean same-job candidate; not an HA 2% + B5 formula copy |
How to choose
- Want The Ordinary's exact product? Use the Original Formulation page and current package. S.NATURE does not reproduce its formula claim.
- Want a Korean serum for a broad hydration layer? S.NATURE is the more relevant product to investigate. Confirm the 50 ml SKU, delivery country, current label and seller.
- Want the Ceramides version? Start a different comparison. Do not use this page as if the two The Ordinary versions were interchangeable.
- Need a guaranteed texture or skin result? Treat tack, slip, layering, pilling, glow and tolerance as open personal-test questions. This page does not predict every person's experience.
- Shopping for acne, eczema, dermatitis or redness treatment? This is a cosmetic comparison, not a diagnosis or treatment recommendation.
Related serum and hydration comparisons
These pages also separate a shared routine job from a formula claim:
- Bioderma Sensibio Defensive Serum vs SKIN1004 — a leave-on hydration job comparison with different formula systems.
- LANEIGE Cream Skin vs AESTURA — a milky hydration-layer comparison, not a shared formula.
- Rhode Glazing Milk vs haruharu — a milky barrier-hydration job comparison with different published signals.
- Charlotte's Magic Cream vs S.NATURE cream — a separate rich-moisturizer comparison; its S.NATURE cream SKU is not this serum.
What this page is not saying
We are not saying S.NATURE contains The Ordinary's 2% HA + B5 system, has the same molecular-weight mix, matches the same texture, is cheaper in every market, gives the same hydration, is hypoallergenic or is clinically equivalent. We are saying that the two exact SKUs can be investigated for a broad hydration-serum routine job while their labels, variants, sizes, prices and evidence remain separate. Check the current package before purchase.
