2 formulas, one number that matter

Read the actives column first — it is the apples-to-apples comparison. $ per gram of active is what the working ingredients cost you; the base-formula score is supporting evidence, not the verdict.

03 / The original

Why the original is the original

MIZON's essence lists Snail Secretion Filtrate 3rd of 26 ingredients, in a fuller formula that also carries Houttuynia Cordata Extract, Centella Asiatica, and three hyaluronic-acid forms. Like almost every snail-mucin product on the market, MIZON does not disclose a percentage — this page works from verified ingredient position, not an invented number.

COSRX's Advanced Snail 96 Mucin Power Essence lists Snail Secretion Filtrate 1st of 12 ingredients — the very first ingredient, in a much shorter formula. Being first in a 12-ingredient list is, structurally, at least as concentrated a placement as third in a 26-ingredient one — real evidence COSRX is not a watered-down copy, even though neither brand's percentage is independently confirmed here (COSRX's product name implies "96," but that figure is not lab-verified in this catalog, so we don't print it as fact).

Both are the same essence format, so you're not trading away a texture difference. What MIZON adds that COSRX's spare formula does not: Houttuynia Cordata Extract, Centella Asiatica, and a fuller three-form hyaluronic-acid complex. COSRX is the single most recognized snail-mucin essence in K-beauty for a reason — a shorter, mucin-forward formula, in a bottle twice MIZON's size, for well under MIZON's price.

shared with original not shared rare marker — weighs more in the score

What matches
Lists Snail Secretion Filtrate 1st of 12 ingredients — the very first ingredient, a structurally more prominent placement than MIZON's 3rd of 26. The single most recognized snail-mucin essence in K-beauty, in the same essence format.
What differs
A much shorter, 12-ingredient formula — no Houttuynia Cordata Extract, no Centella Asiatica, no three-form hyaluronic-acid complex the way MIZON layers in. Neither brand's percentage is independently confirmed here.
Who it's for
The winner if you want the snail mucin itself at the most prominent verified position, for meaningfully less money — $18.50 versus $26, in a bottle twice MIZON's size.

05 / Methodology

How we verified this

Verified 2026-07-29

Every formula on this page was tokenized — split into its individual INCI ingredients — and matched against the EU CosIng ingredient database, so "Aqua," "Water," and "Eau" all resolve to the same ingredient.

The base-formula match score works like this: sharing a rare ingredient counts far more than sharing a common one. Almost every serum contains water and glycerin — that proves nothing. Almost nothing contains Ethoxydiglycol or Laureth-23, so when a candidate shares those with the original, it says something real about how the formula was built. (For the statisticians: it is an IDF-weighted Jaccard similarity over the normalized ingredient lists.)

Scores are computed, not opinions. The verdict tags are our editorial read of the actives, the scores, and the prices — and the methodology stays public so you can disagree with us precisely.

06 / Questions

Frequently asked

What is the best MIZON Snail Repair Intensive Essence dupe?
COSRX Advanced Snail 96 Mucin Power Essence ($18.50) lists Snail Secretion Filtrate 1st of 12 ingredients — the very first ingredient, a more prominent placement than MIZON's 3rd of 26 — in the same essence format, for well under MIZON's price.
Does COSRX really have 96% snail mucin?
That figure comes from the product's own name, not an independently lab-verified percentage in our catalog. What we can verify: Snail Secretion Filtrate is the first ingredient in COSRX's 12-ingredient formula — a structurally prominent placement, whatever the exact percentage is.
Is COSRX Snail Mucin as good as MIZON Snail Repair Essence?
On the shared active, COSRX's more prominent ingredient-list position suggests it's at least comparably concentrated. MIZON's fuller formula adds Houttuynia Cordata Extract, Centella Asiatica, and a three-form hyaluronic-acid complex that COSRX's shorter formula doesn't replicate — a real reason to prefer MIZON if you want those extras.
