Yes, snail mucin sounds like a funky skincare ingredient in the Western world, but dermatologists say it is an excellent skin moisturizer that boosts collagen production. One of the most revered snail mucien brands is COSRX, and they just dropped some major goodness

Snail mucin is a strange-sounding, unique skincare ingredient that has taken over TikTok, but don't worry: Dermatologists consider it an excellent ingredient to boost moisture and collagen production, which is ideal for achieving a more youthful-looking complexion.

And when it comes to snail mucin skincare products, Korean beauty brand COSRX is the gold standard. Although the annual Amazon Prime Day beauty deals event wrapped last night, shoppers can still save up to 51% off COSRX's snail mucin products RN — and TBH, our senior electronics editor Brandon Carte, has already stocked up.

As our beauty editor, a significant part of my job is to ensure every single item featured on our site lives up to its respective claims and will help readers achieve their beauty goals, whatever they may be. And as someone who loves shopping sales, I spent days carefully monitoring the prices of various COSRX snail mucin products before, during, and after the big Prime Day deals event. Here are my thoughts on the brand's eight best Prime Day beauty deals worth your hard-earned money. But act fast: Prime Day ends tonight, July 12, meaning they will return to regular prices soon.

Snail Mucin 92% Moisturizer

At 51% off, shoppers will save the most when they purchase the COSRX Snail Mucin 92% Moisturizer. It's a lightweight gel-cream that ensures normal, dry, and mature skin types are hydrated, but those with oily and combination skin aren't looking like an oil slick after an hour of wear.

This hypoallergenic face cream earned its name because it's made with an impressive 92% snail mucin. As for the other ingredients, you can find moisturizing dimethicone, soothing panthenol (vitamin B-5), and allantoin for additional hydration, exfoliation, and anti-hyperpigmentation power.

Snail Mucin 96% Power Repairing Essence

Great news! This top-rated skin essence was sold out yesterday, but is finally back in stock today — and it's an impressive 40% off!

Dull, damaged skin, be damned. Chockfull of 96% snail mucin, it's easy to see why the COSRX Snail Mucin Essence went viral on TikTok and is a must-have for model-actress Emily Ratajakowski. The Gone Girl actress shared an Instagram Story of her current skincare routine, and the Essence was a must British Vogue previously reported.

This highly-concentrated Essence plumps the skin, boosts elasticity, and minimizes the look of wrinkles and fine lines. It also brightens dull, tired, and uneven skin. Notably, a casual 38,000+ Amazon reviewer praise that it offers long-lasting moisture without a greasy finish.

Snail Mucin 96% Essence + Vitamin C 23% Serum

This gift-worthy duo comes with the above mentioned essence and a lightweight vitamin C serum that neutralizes free radical damage to protect the skin.

Dermatologists love vitamin C because it lightens dark spots, promotes collagen production, and strengthens the skin. It even helps boost sun protection when layered underneath a face sunscreen. "So not only does it help correct existing damage, but it will help prevent additional damage as well," board-certified dermatologist Dr. Supriya Tomar, M.D. previously told us.

Advanced Snail Peptide Eye Cream

After a few weeks of regular use, you'll begin to wonder where your dark circles went. Made with 73.7% snail mucin and 2% niacinamide, you can't go wrong with this beauty gift. The two ingredients work together to seriously brighten undereye darkness and support a healthy skin barrier. It's also infused with a blend of five peptides that reduces fine lines and helps fade dark sports even further. No wonder thousands of shoppers are OBSESSED with this piece.

Advanced Snail Mucin Gel Cleanser

Only have $10.50 left to spend on a new beauty product? Opt for this budget-friendly face wash from COSRX. It rinses away makeup, oil, and dirt, without overstripping the skin so your skin's balance isn't thrown into disappair.

A must-have for all skin types, users only need to lather a pea size amount of cleanser in their palms before massaging the foaming awsh into their skin.

One Amazon reviewer loves their cleanser so much, they put their signiant other onto the brand, and now the couple both use COSRX daily. "He swears by this stuff! We love the whole brand/line actually. It’s quality because you need SO so so little to have full lather. Doesn’t over dry, scent is there but not offensive at all," says their 5-star review.

Advanced Snail Hydrogel Eye Patch

Dermatologists love undereye patches because they deliver a concentrated burst of ingredients to the delicate undereye area. Available in two sizes — large and small — for a custom fit, it's easy to refresh dark, tired undereye areas.

In addition to snail mucin, it's infused with niacinamide, sometimes called vitamin B-3. It's one of my all-time favorite skincare ingredients because it pairs nicely with all skincare ingredients and helps soften fine lines and wrinkles, plus strengthens weak skin.

Snail Mucin Sheet Mask (10 Pack)

Treat yourself (or your lucky bestie) to glowing skin without breaking the bank. These soft sheet masks are drenched with the signature Power Essence to deliver an extra concentrated dose of moisture.

Need further proof? Well, beyond amassing a 4.7-star average from nearly 1,100 Amazon reviews, many shoppers highlight the dewy skin finish as a major win.

"This will leave your skin so hydrated and shiny. I used to struggle with dry skin, especially in the mornings. After using this before bed, it changed my skin texture entirely. I love this product line — it's for sure my go-to," says one elated Amazon reviewer.
