‘I wasn’t satisfied by the viral snail serum however months later, I can not be with out it’
Our writer tested the viral K-beauty serum for seven months and shares whether it really lives up to the hype
With Amazon’s Prime Day sale finally here, a range of viral beauty products have been massively reduced. This includes a cult-favourite snail serum that claims to deliver ‘glass skin’ results.
The COSRX Advanced Snail 96 Mucin Power Essence created quite the buzz some years ago on social media. Some users even praised it as ‘Botox in a bottle’.
Now available for £11.40, down from £23.99, the serum has thoroughly impressed users on TikTok and Instagram, who have raved over its remarkable benefits. Packed with 96.3 percent Snail Secretion Filtrate, the formula is claimed to maintain skin hydration while combating dark spots and ageing signs such as fine lines and wrinkles.

Now available on Amazon, it’s achieved cult status amongst beauty enthusiasts who turn to it in pursuit of flawless skin. The serum harnesses the snail mucin’s naturally hydrating properties, which feature glycolic acid, glycoprotein enzymes and copper peptides – typically found in high-end products that command premium prices, reports the Daily Record.
This isn’t the only product in the industry harnessing the power of snail mucin, as shoppers can get the Beauty of Joseon Revive Serum Ginseng + Snail Mucin for £11.25 from LookFantastic. It contains 63% ginseng root water as well as snail mucin.
COSRX Advanced Snail 96 Mucin Power Essence is now on sale

Featuring snail mucin in its formula, this serum is designed to repair and rejuvenate the skin to help prevent dryness and aging. With a lightweight mixture, this essence should hydrate and soothe the skin.
Elsewhere, Byoma’s Phyto-Mucin Glow Serum, £15 Cult Beauty, is a a lightweight daily serum designed to boost bounciness and smooth the complexion all whilst helping achieve that yearned after ‘glass skin’.
But with such good results from products containing this hero ingredient, we can see why this relatively affordable COSRX serum has gained such popularity, but does it genuinely deliver results?
That’s precisely what Trends Writer Lucy Farrell set out to discover. Following daily use over the past seven months, she’s now incorporated it as a staple in her skincare regimen – and has this to say.
‘My skin is glowing’
As a beauty lover, I’m always keen to try the latest skincare products that promise glowing, healthier-looking skin. So when I kept seeing people rave about the COSRX Power Essence, I had to see what all the fuss was about.
I first wrote about the serum back in November after using it for four months. At the time, I wasn’t completely sold — I found it a little drying and didn’t notice the ‘glass skin’ effect so many fans talked about.
But months later, my opinion has changed. My skin now looks brighter, smoother and more even-toned, and it’s become a product I don’t want to be without.
When I first tried it, I was put off by the tacky texture and worried it would leave my skin feeling sticky. Thankfully, it absorbed quickly, but despite following the instructions, my skin felt drier during the first couple of weeks and I wondered whether it just wasn’t for me.
Since then, I’ve made a few tweaks that have made a big difference. The first was applying it to damp skin straight after cleansing rather than waiting for my face to dry. I’d seen skincare fans recommend this online, and I found it helped lock in moisture.
I also started using it twice a day instead of just once. While I got through the bottle faster, I felt I saw much better results. Those two small changes completely transformed my experience, and I’ve officially become a full-time snail serum convert.
Final thoughts
The age-old saying ‘good things come to those who wait’ applies to many aspects of life – and skincare is certainly one of them. After being patient and consistent with the serum, I can see that my skin maintains a lasting radiance without appearing oily, and my overall complexion has become more even.
However, as I mentioned, users shouldn’t anticipate overnight results, as this product genuinely needs time to work its magic. I also believe it’s crucial not to use it sparingly and to apply it regularly in order to see genuine improvements.
