Cosrx Advanced Snail 96 Mucin Power Essence

If you buy one Korean skincare product, Seoul would tell you to start here.

The COSRX Snail 96 essence is the best-selling K-beauty serum in the United States for a simple reason: it does one job, plumping and smoothing the skin, and it does it at a price that makes a daily habit easy. The texture is a clear, slippery gel that sinks in within a minute and leaves skin looking bouncy rather than greasy.

Why it made Seoul's edit

• 96.3% snail secretion filtrate, the highest concentration you will find in a mainstream essence.
• Helps skin look smoother and more even, including the dark marks breakouts leave behind.
• Lightweight enough for oily skin, hydrating enough for dry skin. It layers under anything.
• Fragrance-free, alcohol-free, and no essential oils.

Good for

Dehydrated, dull, or textured skin. Anyone building a first Korean routine. Skin that is recovering from a breakout.

Skip it if you have a known allergy to mollusc-derived ingredients.

How to use

1. Cleanse, then apply toner.
2. Press 2 to 3 drops over your face and neck. Pat, do not rub.
3. Follow with moisturizer. Use morning and night.

Key ingredients, in plain English

• Snail secretion filtrate (96.3%): a mix of mucin, glycoproteins, and hyaluronic acid that holds water on the skin and supports a smoother surface.
• Sodium hyaluronate: pulls moisture into the upper skin layers.
• Panthenol: pro-vitamin B5, a calming hydrator.

What you get

One 100 ml (3.38 fl oz) bottle with a pump. Used twice a day, it lasts about 45 days. That is why we flag it for replenishment at the 45-day mark.

Pairs well with

COSRX Low pH Good Morning Cleanser before it, and Laneige Water Sleeping Mask over it at night.
