Choose the COSRX Snail 96 essence if you want snail secretion filtrate as the main ingredient; choose the SKIN1004 Centella Ampoule if you want centella and an ingredient list without snail secretion filtrate.

Both are 100 ml (3.38 fl oz) on Amazon US, so size won't decide this for you. The label and the directions will. We read COSRX's and SKIN1004's own product pages and the Amazon listing titles on November 1, 2026. We don't list prices, we haven't tested either bottle, and we don't promise results.

Side by side

Note the first-ingredient row. SKIN1004's US page lists water, glycerin and butylene glycol before centella asiatica extract, so the bottle is not pure centella extract. Read the label on the bottle you receive if that matters to you.

How each brand says to use it

COSRX's directions for the Snail 96 essence:

• SKIN1004's directions for the Centella Ampoule are shorter: drop an appropriate amount, spread it evenly over the skin and pat it in. The brand describes the texture as watery and slippery.
• COSRX's fact panel says the essence keeps for 36 months from manufacturing or 12 months after opening. SKIN1004's page doesn't give a period, so check the box.

1. After cleansing and toning, apply a small amount to the whole face.
2. Gently pat it in with your fingertips.
3. Follow with a moisturizer, then makeup in the morning or a mask at night.

Label details that may decide it

• Snail secretion filtrate: it's the first ingredient in the COSRX essence and doesn't appear on SKIN1004's published list. If that's the ingredient you want to avoid, compare the two lists; the lists alone don't tell you where every other ingredient comes from.
• Fragrance: neither brand's published ingredient list includes fragrance.
• Length of the list: SKIN1004 lists seven ingredients and COSRX lists 13. Either is short enough to check against products you already use.

Which one should you buy?

Start with the ingredient you're shopping for. If you came looking for snail mucin, the COSRX essence is the one built around it. If you came looking for centella, the SKIN1004 ampoule names it as its key ingredient.

You don't need both to start. Add one bottle, patch test it first, and keep the rest of your routine the same for a while so you know how your skin gets along with it.
