I found out recently that I am informally known on my team as the girl who really likes snail mucin (put that on a T-shirt, baby!!!). And with that newfound role, I fear it’s my responsibility to tell you about one of the best Amazon Prime Spring Sale deals out there.

By now, you’ve probably seen this bottle everywhere – and if not, pls come join us! The COSRX Snail Mucin 96% Power Essence is currently discounted in Amazon’s Spring Sale with 52% off. When I saw that, I bought two bottles (always need a backup) and decided it was my public duty to make sure everyone knew about the discount on this liquid gold product for every type of skin, from sensitive to acne-prone.

What is the COSRX Snail Mucin 96% Power Essence?

Now you might be like, “What is it? First of all – lets talk about snail mucin. Using snail mucin in skincare sounds so bizarre, it *still* seems like a fleeting trend. But actually, snail mucin has been used in traditional Korean and Chinese medicine for generations. And in recent years, it has become one of the most popular hydrating ingredients used in mainstream skincare.

While some skincare products (I’m thinking Rodial Snake Oil Drops) sound as though they contain an animal product but actually don’t, that’s not the case here. The core ingredient is snail secretion filtrate – so the secretion (goo) of a snail. Vegans, you may want to skip this one out, but know that zero snails are harmed in the process.

Snail Mucin 96% Power Essence is a thick, scentless, clean serum that has a slightly slippery texture – think hyaluronic acid, which the serum does contain! I’ve been buying COSRX’s formula for years, usually at full price (£25.99) – so, yeah, now is the time to snag one if you’ve been wanting to try it!

I’ve found that it works best on damp skin, so you can either use it right after washing your face or pull out your favourite facial mist as a skin prepper. Feel free to slather it all over your face, neck, chest, and hands for the ultimate hydration reset because it’ll absorb within minutes. I’ll even use it to prep my skin before applying makeup if I want a little extra glow.

Speaking of glow, that’s exactly what this bottle does. It helps to boost collagen production and rejuvenate the skin, so after a few weeks of loyal use, you’ll notice a brighter complexion. And because collagen production = less fine lines, your skin will look plumper too.

Also, don’t sleep on other COSRX fan-favourite products like the Good Morning Cleanser, pimple patches, and BHA Toner Pads. You can also stock up on these discounted faves below in the Amazon Spring Sale (which, aka, is ending on Monday 31 March).
