Social media users have been sharing their results after using the product.

If you've been curious to see what all the hype is about, now is the perfect time. You can get the viral snail mucin serum for just $14 on Amazon right now. It regularly retails for $25.

Cosrx snail mucin hydrating serum: $14 (43% off)

This TikTok-approved snail mucin serum is made with 96% snail secretion filtrate (snail mucin) and is designed to protect the skin from losing moisture. Snail mucin may also promote collagen production, which can help reduce fine lines and wrinkles.

"I was initially skeptical about using anything related to snails on my face, but the results spoke for themselves," an Amazon reviewer says. "This serum is like a hydrating blanket for the skin! From the very first use, I could feel an added layer of moisture without it feeling greasy. My skin felt plump, and there was a noticeable reduction in the appearance of fine lines."

Why we like the Cosrx snail mucin hydrating serum:

With an Amazon rating of 4.6 stars and over 50,000 reviews, it's safe to say that Amazon shoppers approve of this TikTok famous product.
It's unscented, which is great for those with sensitive skin or fragrance sensitivities.
It is not tested on animals.

When is Amazon Big Deal Days?

The Amazon Big Deal Days sales event (also known as October Prime Day) kicks off at midnight PT (3:00 a.m. ET) on Tuesday, Oct. 10 and runs through Wednesday, Oct. 11, 2023.

What else is on sale during Amazon Big Deal Days?

During the Amazon Big Deal Days sales event, you'll also find big discounts across all of Amazon's departments, including home, tech, kitchen, fitness and so much more. This is the perfect time to kick off (and potentially even finish) your holiday shopping, without having to deal with Black Friday crowds and having the gifts you want to purchase being sold out. You'll find deals on luggage for your holiday travels, too.

Do you need to be a Prime Member to shop Prime Big Deal Days deals?

While some of the best Amazon Prime Big Deal Days offers are Prime-exclusive or invite-only, there will also be tons of deals that are open to all shoppers. So even if you don't have an Amazon Prime membership, there will be deals available to you.

If you want to shop the best deals, though, you'll want to sign up for a 30-day free trial of Amazon Prime. Prime memberships costs $14.99 per month or $139 per year, and include access to Amazon Prime Video (Thursday Night Football) and a number of other great perks.

What other stores are holding competing early Black Friday sales?

Savvy shoppers know that any of the Amazon Prime Day events offer the perfect time to find tens of thousands of popular products on sale from Amazon, including some at their lowest price of the year. However, many other popular online and retail merchants, such as Walmart, Target, Best Buy and even your favorite department stores, such as Macy's, all tend to kick off sales either at the same time or around the same dates as Amazon Big Deal Days.

Best Buy's 48-Hour Flash Sale is happening on Oct. 10 and Oct. 11, the same days as Amazon's Prime Big Deal Days.
Walmart's Holiday Kickoff sale will run from Oct. 9 through Oct. 12.

Do products on sale during Amazon Big Deal Days sell out?

You bet they do -- and sometimes things sell out within hours. If you see something on sale that you want to get your hands on during the Amazon Big Deal Days sale, order it right away. Often, quantities are limited. Once a product is sold out at the sale price, Amazon won't always restock right away and when it does restock, the sale price likely won't be offered.

Can products bought from Amazon during Amazon Big Deal Days be returned?

Unless it specifically states in the product description or near the "add to cart" and "buy now" buttons that the product being offered on sale is a final sale or not returnable, Amazon's regular return policy for that product will be honored.

On the right side of a product description on Amazon, just below the "buy now" button (and where it says "ships from and sold by"), look for the heading that says "returns."

If the text says, "eligible for return, refund or replacement within 30 days of receipt," that's the return policy that will be honored. However, you may be responsible for paying return shipping to Amazon, unless you drop off the product as a Whole Foods or Kohl's, which accepts some Amazon returns.
