Cosrx’s K-beauty snail mucin reduced to just $12 for Prime Day
Save on the viral advanced snail 96 mucin power essence, as well as the eye treatment, serum and more
From Beauty of Joseon to Anua, the world of Korean skincare is booming. With billions of views on TikTok, CORSX is another brand to know — and now is your chance to try the snail-powered formulas, thanks to Amazon Prime Day 2025.
The online giant has kicked off its annual October event — dubbed Prime Big Deal Days — with thousands of deals on everything from Color Wow haircare to the Meta Quest 3s.
If it's skincare, I’d recommend turning to Cosrx. The K-beauty brand has gained popularity in the last few years thanks to the “glass skin” trend. Its bestselling product — the advanced snail 96 mucin power essence — is beloved for soothing and hydrating skin, while blurring fine lines.
When The Independent’s beauty writer Lucy Smith reviewed Cosrx’s full roster, she described the formula as “wonderful, clean skincare that gets to the heart of the problem, be it dullness or clogged pores, for a reasonable, mid-range price.” Now, the products are even cheaper thanks to Prime Day.
COSRX advanced snail 96 mucin power essence
“Though it is very slimy – as you’d expect – COSRX’s hero snail 96 mucin essence requires only a small drop to treat the whole face,” our beauty writer Lucy said. “It leaves the skin feeling as though it’s had a generous drink of water, thanks to humectant (water-attracting) hyaluronic acid, and feels ever so slightly creamy despite its transparent liquid appearance.” The mucin is said to repair skin, helping to boost luminosity and reduce the appearance of fine lines — Lucy saw pump results and a healthy glow after continued use. Now, you can save 48 percent in Amazon’s sale.
COSRX the 6 peptide skin booster serum
Reduced by 36 percent, now’s the time to try COSRX’s peptide skin booster serum. “It’s cooling to apply and disappears almost immediately, leaving the skin feeling as though it’s just had an ice massage,” beauty expert Lucy said. Powered by peptides — which are often described as a more gentle alternative to retinol — Lucy noticed that the two lines forming between her eyebrows looked less pronounced. “It’s a lovely, refreshing way to start each day,” she concluded.
Cosrx hyaluronic acid moisturising cream
This rich, hydrating cream aims to replenish and retain the moisture in skin. A powerful duo of hyaluronic acid and sea buckthorn oil works to improve skin elasticity, while soothing irritation and plumping your complexion. Plus, it’s gentle enough for sensitive skin thanks to being free from artificial fragrances and harsh chemicals. With 36 percent off, there’s no better time to try the moisturizer.
Cosrx pink peptides collagen hydrogel eye patch
This revitalizing treatment is formulated with collagen, peptides, and niacinamide to firm, brighten, and hydrate the under-eye area. Touted as a quick fix for blurring fine lines and masking dark circles, the cooling, gel-like texture of the treatment is sure to wake up tired eyes each morning during winter.
