If you’re aware of snail mucin’s rebrand from mollusk secretion to skin care solution for soothing and hydrating stressed-out skin, you’ve heard of the cult-favorite skin care brand championing the ingredient, CosRx. The Korean brand is praised for its use of snail mucin at an affordable price point— unlike its pricier culinary cousin, escargot.

Founded in 2013, Cosrx has earned a reputation for creating budget-friendly beauty essentials that target common concerns for dry to oily skin types. The brand’s mission is to create simple, effective skin care solutions with formulas that prioritize skin health. The brand’s name is a combination of “cosmetics” and “RX,” representing the focus on individual, “prescribed” skin remedies to individual concerns. Cosrx is now one of the most recognizable names in K-beauty, and is celebrated for its focus on research-backed ingredients, such as snail mucin.

Perhaps CosRx’s most popular product, the Advanced Snail 96 Mucin Power Essence is a fast-absorbing, feather-light essence that hydrates and keeps your skin glowing all day long. This top face serum targets dull, rough, and damaged skin, and dark spots and scars with its 96 percent snail secretion filtrate that delivers rich nourishment through quick absorption. It also includes sodium hyaluronate that plumps the skin with intense hydration.

Editor testing and review notes: “Cosrx snail mucin essence feels like a lightweight gel on your skin, and dries down to a dewy finish that made my complexion look hydrated and feel silky. After one full year of using the product twice daily, I’ve noticed less redness and a subtle plumping effect that’s smoothed fine lines, particularly on my forehead and around my eyes.” — WWD Shop Senior Beauty and Lifestyle Commerce Editor Claire Sullivan

Looking to heal an acne outburst overnight? Look no further than Acne Pimple Master Patches to soothe problem areas while preventing further breakouts. These top acne patches are made with hydrocolloid, which draws out excess oil and pus from pimples to help heal skin. These patches are so thin that they practically disappear on the skin, and each sheet contains two sizes of adhesives to cater to zits of all sizes.

Editor testing and review notes: “These pimple patches are super clear, so I always feel comfortable wearing them during the day. They make embarrassing zits almost undetectable, which is ideal for a busy day when I’m worried about that being a main focus. My breakouts always look smaller and less inflamed after I wear one of the Cosrx patches for a few hours.” — WWD Shop contributor Fernando Snellings

Cosrx Ceramide Lip Butter Sleeping Mask

$14.39 $19.00 24% off

Buy Now at amazon

Cosrx makes moisturizing your lips easy enough to do it in your sleep. Actually, that’s kind of the whole point of the brand’s Lip Sleeping Mask. While you sleep, ceramides envelop your lips in a creamy barrier, keeping them moisturized and refreshed. Shea butter supports the ingredient, ensuring that your lips feel hydrated by the time you wake up.

Editor testing and review notes: “I was seriously impressed by the texture of this Cosrx lip mask. most lip masks on the market right now have a super-thick feel to them that makes them hard to wear comfortable during the day. This one, on the other hand, has a whipped texture that melts onto the lips when you smooth it on. I apply it while I’m doing my makeup, then blot it off with a tissue to prep my lips for a swipe of bold lipstick.” — Sullivan

Cosrx 15% Niacinamide Face Serum

$13.99 $25 44% off

Buy Now at amazon

This potent serum targets acne, uneven skin tone, hyperpigmentation, and excess oil by way of its key ingredient — niacinamide.

If you’re always looking for your next holy grail acne spot treatment or oily skin serum, this is an immediate add to cart.

Editor testing and review notes: “This niacinamide face serum layers so well with any other products I team it with. Some niacinamide serums can feel heavy on my combination skin, but this one feels incredibly lightweight on my skin and absorbs within seconds of me applying it. It’s a great option for boosting hydration (and helping to brighten my tone) without feeling like I need to be weighed down by heavy creams and serums.” — Sullivan

The nourishing gel-cream formula absorbs quickly, imparting deep hydration and leaving your skin feeling refreshed. Snail mucin and sodium hyaluronate are the key ingredients in this top moisturizer for dry, sensitive skin.

Editor testing and review notes: “Simply put, this is an excellent basic face cream. It provides enough moisture to keep my skin feeling soft all day, but never greasy. A little goes a long way, so I rate the value five stars, too. My favorite way to wear it is over a few pumps of the Cosrx snail mucin serum — these two give my skin a dewy finish together.” — Sullivan

The natural ingredients help reduce breakouts and soothe the skin simultaneously. Plus, it’s beginner-friendly and under $15 during Amazon Prime Day.

Editor testing and review notes: “This exfoliating toner is on par with similar cult-favorite options that retail for double the price. Honestly: I did a side-by-side test with Cosrx’s toner and a $39 alternative, and they gave me the exact same pore-clearing results. My skin can be reactive, but this toner doesn’t cause a redness or irritation flare up. I use it every few nights to clear out my pores and prep my skin for smoother makeup application.” — Sullivan

Editor testing and review notes: “This is a great face mask that you don’t need to save for a special occasion — at just over $2 each when you buy a 10 pack, there’s plenty to share. The mask is thin but packed with solution, so you have plenty of excess to pat on your chest, arms, and hands, if you wish. I find that I need to stay still when I have it on to prevent it from sliding around, but otherwise, I have no critiques.” — Sullivan

How We Tested & Selected the Best Cosrx Skin Care Products

Since 1910, WWD — often referred to as “the fashion bible” — has been the leading industry voice of authority for senior executives in the global women’s and men’s fashion, retail and beauty communities, while also informing the consumer media that cover the market. Today, WWD’s breaking news and trend coverage continues to be a trustworthy resource for both fashion insiders and consumers alike. Our shopping editors continue to uphold WWD’s editorial standards and values with quality, expert-backed product selections.

To create this list of the best Cosrx skin care products, a panel of beauty editors and product testers tried 17 of the K-beauty brand’s bestselling skin care finds. Some of these products were sent to us from the brand, while others were independently purchased by our editors for testing purposes. A total of five testers with various skin types and skin concerns then evaluated the products, judging them against criteria like packaging, texture, value, and results. Any products with faulty packaging, lackluster results, or texture issues (i.e., pilling with other products) were removed from our list. The nine Cosrx products on our list passed with flying colors, finding permanent spots in many of our testers’ skin care routines. Learn more about us here.

Meet the Testers

A panel of five men and women contributed to product testing for this guide. Our testers represent a range of skin types — from dry to combination to sensitive and acne prone. These testers include WWD Shop Commerce Director Adam Mansuroglu, Senior Beauty & Lifestyle Commerce Editor Claire Sullivan, and Commerce Writer and Producer Olivia Cigliano. Each product on our list was tested for a duration of two weeks minimum, and each product was tested by at least two members of our panel to ensure accurate, unbiased reviews. Our panel will continue to test the Cosrx products on this as well as new releases and will update the story with our results.
