COSRX Snail Mucin vs The Ordinary Hyaluronic Acid 2% + B5 vs Torriden DIVE-IN

Two hydrating serums shoppers often weigh against the COSRX essence: a cheap hyaluronic acid serum and a Korean low-molecular hyaluronic acid serum.

	COSRX Snail Mucin Essence	The Ordinary Hyaluronic Acid 2% + B5	Torriden DIVE-IN Serum
Price	$25 list, $20.90 at Dermstore	$10.70 (original formula)	$21.60 at Vitacost

Main ingredients	96.3% snail secretion filtrate, sodium hyaluronate	2% hyaluronic acid with vitamin B5	Five forms of hyaluronic acid, panthenol

Pick The Ordinary if you want the lowest entry price and no snail ingredients. Pick Torriden if you want a hyaluronic acid serum from a Korean brand. Pick COSRX for the most product per dollar and a fragrance-free formula.

Before you buy

Check the size

The 100 ml bottle is the best value. The 30 ml size is there if you want to try it first.

Match the listing to COSRX

Amazon uses two product names for this essence. Look for COSRX branding and an ingredient list that starts with snail secretion filtrate.

Watch for deals

It lists at $25, but Amazon deals have cut it to about half. Subscribe & Save takes off a little more.

Note the opening date

COSRX says to use it within 12 months of opening.

What to know before you buy

COSRX keeps the formula short. These are the trade-offs that come with it.

It is one step, not a routine

COSRX tells you to follow it with a moisturizer. It has no SPF, so you still need sunscreen in the day.

No active ingredients

The list has no retinoid, exfoliating acid or vitamin C. It is a hydrating step that sits alongside those products.

Snail-derived, so not vegan

The main ingredient is snail secretion filtrate. COSRX says the snails are not harmed but does not give more detail on how it is collected.

A slightly tacky feel

COSRX calls it a lightweight, fast-absorbing essence, though it can feel a little sticky at first.

Two names on store pages

Amazon listings use both Advanced Snail 96 Mucin Power Essence and Snail Mucin 96% Power Repairing Essence. Check the 100 ml size and COSRX branding.
