Snail secretion filtrate in a skincare formula
A moisturizing ingredient derived from snail secretion, listed in leave-on formulas.

Snail mucin is a common name; the INCI name is more specific
“Snail mucin” is a consumer-facing phrase. Snail Secretion Filtrate is the INCI name used for a filtered snail secretion ingredient. Neither label wording gives the exact mixture or a standardized amount of any single molecule.
Compare snail essence and cream by the step they fill
A high percentage on the front label may refer to the ingredient as supplied in a formula; it does not tell you the product’s feel or prove that a higher percentage performs better. Compare the whole ingredient list and the brand’s directions.
An essence and a cream can share snail secretion filtrate while serving different routine steps. If your moisturizer already works for you, another product with the same highlighted ingredient is optional.
| Format | How to compare |
|---|---|
| Essence | Does a light leave-on step fit your routine? |
| Cream | Does it provide the moisturizer texture you want? |
| Percentage | What exactly does the brand say the number measures? |
Snail secretion filtrate: research findings and limits
A three-month, randomized, double-blind vehicle-controlled study enrolled 50 women aged 45–65 with photoaged skin. A regimen combining snail secretion filtrate and snail egg extract reported lower water loss and improvements in some firmness- and elasticity-related measures versus vehicle. The regimen also included sunscreen; the manufacturer funded the study and two authors disclosed company ties.

Snail secretion filtrate: common questions
Does 96% mean it works better than a lower percentage?
Not necessarily. A percentage does not show how the finished formula will feel or perform on your skin.
Did the cited trial test snail secretion filtrate by itself?
No. The trial tested a regimen combining snail secretion filtrate and snail egg extract, with sunscreen also in the regimen. It cannot isolate filtrate’s contribution or predict the result of every snail essence.
Do I need both Snail 96 essence and Snail 92 cream?
You do not need both just because they contain snail secretion filtrate. COSRX places Snail 96 essence before moisturizer, while Snail 92 is a cream that can fill the moisturizing step. Their full ingredient lists differ. If you already like your cream and want to try an essence, compare Snail 96 for that role; if you want to replace your cream, start with Snail 92’s texture and directions. The label percentages do not tell us which works better.
