  • I was honestly freaked out by the ‘snail’ bit at first, but this stuff is like a drink of water for my skin. it looks glowy and feels hydrated all day. it’s kinda gooey going on, but melts in fast. i’ll be keeping this in my routine for sure.

COSRX Advanced Snail 96 Mucin Power Essence is a hydrating essence made with 96.3% snail secretion filtrate, plus betaine, sodium hyaluronate, allantoin and panthenol. It keeps skin hydrated, soft and comfortable, and gives a plump, dewy, glass-skin look under your moisturiser.

What it does

Snail secretion filtrate, or snail mucin, is a slippery, water-binding fluid used in Korean skincare for hydration and a smoother feel. Sodium hyaluronate and betaine add more hydration, while allantoin and panthenol help skin feel calm and comfortable.

Why we chose it

It is a short, simple hydration step with thirteen ingredients, and COSRX state it is free from fragrance. A short list also makes it easier to work out what your skin is reacting to if you are troubleshooting a routine. It layers easily between toner and any serum or cream.

Best for

  • Dehydrated skin that feels tight
  • Dull skin that wants a dewy glow
  • Skin that feels stressed after actives
  • Normal, combination and dry skin
  • A plumping layer in a glass-skin routine

Not ideal if

  • You avoid animal-derived ingredients: snail mucin comes from snails. SKIN1004 Madagascar Centella Ampoule is a hydrating option that SKIN1004 describe as vegan
  • You want it to replace your moisturiser: it is an essence, so seal it in with a cream
  • You want a targeted treatment for dark spots or lines: it has no brightening or retinoid active

Key ingredients

  • Snail secretion filtrate 96.3%: hydration and a smoother feel
  • Sodium hyaluronate: draws water into the skin
  • Betaine: hydration
  • Allantoin and panthenol: comfort

Texture and finish

A lightweight, silky essence that absorbs quickly. It leaves a soft, dewy finish.

Where it goes in your routine

After cleansing and toner, before serum and moisturiser, morning and evening. Pat 1 to 2 pumps over the face with your fingertips. Finish with sunscreen in the morning.

What to expect

Skin feels hydrated and softer straight away. A plumper, smoother look builds with steady daily use alongside a good moisturiser.

Good to know

Quick facts: 100 ml · 96.3% snail secretion filtrate · Fragrance-free (brand-stated) · AM and PM · COSRX, made in Korea

  • A small amount covers the whole face. COSRX suggest patting it in with your fingertips.
  • If it feels slightly tacky, give it a minute before your next layer.
  • Follow with moisturiser, and sunscreen in the morning.
  • Patch test first if your skin is reactive or you are new to snail mucin.

Good to know

  • Contains snail secretion filtrate (animal-derived): not vegan
  • COSRX state it is free from fragrance, parabens and sulfates
  • No retinoid and no exfoliating acids

Is it sticky?

COSRX describe it as lightweight and fast-absorbing, and most of the reviews we checked call it lightweight and non-greasy. A few mention a tacky feel for a while after applying. If you notice it, use a little less and give it a minute before your next layer.

Is it vegan or cruelty-free?

It is not vegan: the main ingredient is snail secretion filtrate. COSRX state the mucin is collected without harming the snails. We have not seen a cruelty-free certification for it, so we don't label it that way.

Can oily or blemish-prone skin use it?

It depends on your skin. There are no oils in the listed ingredients and the texture is light, so oily skin that also feels dehydrated can use it as a hydration layer. If you dislike any extra dewiness, you may find the finish too much. A small number of reviews from blemish-prone users mention breakouts, so introduce it on its own and patch test first.

Can I use it with retinoids, vitamin C or acids?

Yes, as far as the formula goes: it has no retinoid and no exfoliating acid of its own, so it does not add a second active to your routine. Use it after toner and before your treatment serum, then moisturiser.

Will it help with dark spots or fine lines?

Not directly. It is a hydration essence, with no brightening active and no retinoid. Well-hydrated skin looks plumper and smoother, and that is what this gives you. For dark spots or lines, pair it with a targeted serum.
