Yes, it's snail slime.
No, we're not sorry.

We know. You saw "92% snail secretion filtrate" and made a face. We all did. Then we tried it. And now we're here, running a website about it, because something this good deserves an audience.

For the record: no snails are harmed. The mucin is collected in a snail-friendly environment and processed as a cosmetic material. The snails live their best lives. Your skin gets the benefits.

The COSRX Advanced Snail 92 All in One Cream has been a K-beauty cult favourite for years, and it's easy to see why. It's the jar people finish and then buy again.

This is the one.

The Science Bit

What does snail mucin actually do?

Snail secretion filtrate — the technical name for snail mucin — is one of the best-known ingredients in Korean skincare. Here's what it brings to your routine.

💧

Deep Hydration

Snail mucin is a natural humectant — it helps skin attract and hold on to moisture. A lightweight gel-type cream that glides on without a sticky residue. Skin feels plumper and more comfortable.

🔄

Smoother-Looking Skin

Snail mucin naturally contains small amounts of glycolic acid. In a cream like this the effect is mild, but it helps skin look smoother and more radiant with regular use.

🛡️

Barrier Support

Allantoin and betaine help calm the look of stressed, dry or over-exfoliated skin and support the moisture barrier, so skin feels less tight and reactive.

✨

More Even-Looking Tone

With consistent use, many people find post-breakout marks and uneven patches look less noticeable. It's a gradual, everyday improvement rather than a targeted treatment.

Convinced enough? The jar is waiting.

Why it's a cult favourite.

It's one of the most-reviewed moisturisers on Amazon UK, and the same few themes come up again and again.

Theme 01

People come back for it. Second and third jars are a running theme, and it's a common swap for pricier moisturisers.

Theme 02

The texture surprises people. Lighter and bouncier than the jar suggests, and it sits well under SPF and makeup.

Theme 03

It simplifies routines. Plenty of people use it to replace a separate hydrating serum and moisturiser.

The Formula

92% of this jar is doing the work.

Most moisturisers lead with water and a handful of actives. COSRX Advanced Snail 92 leads with snail secretion filtrate — 92% of the formula. Everything else is there to support it.

Snail Secretion Filtrate 92%
Betaine (hydration booster) Supporting
Hyaluronic Acid Supporting
Allantoin (soothing) Supporting

Fragrance-Free

No added fragrance — a common cause of skincare irritation. A good sign if your skin is easily upset, though a patch test is always wise.

Lightweight Texture

A gel-cream that most skin types get on with, including oily and combination skin.

Short Ingredient List

A lean formula built around one hero ingredient. Check the full ingredient list on the box if you have specific sensitivities.

No Snails Harmed

According to COSRX, the mucin is collected in a snail-friendly environment and processed as a cosmetic material, and the product isn't tested on animals.

How to Use It

Where it fits in your routine.

Korean skincare follows a layering principle — thinnest to thickest. The snail cream sits in the moisturiser step. Here's the full morning routine it belongs in.

01

Cleanser

Gentle, low-pH cleanser. Don't strip your skin before you're about to hydrate it.

02

Toner or Essence

A hydrating toner prepares skin to absorb what comes next. Pat in, don't wipe.

03

Serum (optional)

Vitamin C, niacinamide, retinol — if you use actives, they go here, before the cream.

04

COSRX Snail 92 Cream

Warm a small amount between fingers, press gently into skin. A little goes a long way — the 100g jar lasts months.

⭐ This is the step
05

SPF (morning only)

Always finish with sunscreen in the morning. Might we suggest a Korean SPF? We know one.
