It's that time of year again — Amazon Prime Day is back, and the K-beauty deals are better than ever.
From cult-favorite cleansers to glass-skin-approved serums, this year's sale is overflowing with Korean beauty must-haves that deserve a spot on your top shelf. Whether you're a long-time devotee of the 10-step routine or just dabbling in K-beauty for the first time, Prime Day 2025 is the perfect opportunity to stock up — or finally try — those TikTok-buzzy items you had on your wishlist as the deals are simply too good.
I've been professionally testing beauty products for more than 4 years, and there's no question about it: Korean skincare is my holy grail. It's not just a fad, either; it has long been synonymous with innovation, quality and glow-enhancing ingredients that feel as good as they look.

But what truly sets it apart is its commitment to skin health over quick fixes. On Prime Day, that high standard of skincare suddenly becomes refreshingly affordable. Some of the industry's most beloved brands (think: COSRX, LANEIGE, medicube and Biodance) are offering discounts that make restocking your skincare arsenal practically guilt-free.
With thousands of products on sale starting July 8 and through July 11, navigating the digital aisles of Amazon can feel overwhelming. That's where I come in with my high-powered list of high-powered favorites. I've sifted through the markdowns, scrolled past the not-so-greats and handpicked the absolute best K-beauty buys that are *actually* worth your time and money.
From snail mucin-powered hydrators to barrier-boosting moisturizers and SPF that feels like silk, these K-beauty deals combine performance with sensorial pleasure. And, because Prime Day deals are sometimes fleeting, you should stockpile your cart before they're sold out. It's a limited window to glow up on a budget, and the clock is already ticking.
Ahead, the top Korean beauty products on sale during Amazon Prime Day 2025 that deserve a fast track to your cart. Consider this your ultimate cheat sheet to achieving luminous, glass-like skin —without breaking the bank.
Amazon
Pros: Features a dual-textured design for truly targeted care
Visibly improves skin clarity
Hygienic packaging, perfect for travel Cons: Isn't as hydrating as some of medicube's other formulations, though not a dealbreaker
Ah, yes, the one that started it all. These toner pads are legendary for a reason. They gently exfoliate with AHA and BHA, swipe away gunk you didn't even know was there, and somehow shrink your pores like magic. One pad equals being one step closer to glass skin. It's the product you recommend to your friends, your partner, your mail carrier — because everyone benefits from having cleaner, tighter, happier skin.
The medicube Zero Pore Pad is like your skin's reset button, especially on those days when my pores are having an identity crisis. Each pad is soaked in a mild AHA and BHA formula that gently exfoliates dead skin while helping to unclog pores and smooth texture. What makes it even better is the dual-sided design: one side is slightly textured for a light polish, and the other is smooth to swipe away any residue. You just glide it across your face after cleansing — morning or night — and it leaves my skin feeling impossibly clean without that tight, stripped sensation.

Ingredient-wise, I consider it a thoughtful mix: salicylic acid (hello, blackhead control), lactic acid for gentle exfoliation, and a blend of plant extracts like tea tree leaf and witch hazel to calm things down. I like that it's fragrance-free too (aka, no unnecessary fluff). If you're someone who's overwhelmed by a 10-step skincare routine but still craves that polished, glass-skin look, this is a great little staple to have in your arsenal. It's not a miracle worker, but it's incredibly reliable.
Here's how I use it: I use it about three to four times a week, depending on how my skin's behaving. If I'm wearing more makeup than usual or my T-zone is acting up, I'll use it daily for a few days to bring things back into balance. It's especially good before applying makeup, because it creates this smooth canvas that helps foundation apply more evenly. Just follow it up with your serum and moisturizer, and you're good. It's quick, easy, and doesn't feel like a commitment, which is what I want from my skincare on busy weekdays.
Size: 5.46 ounces (70 pads) | Key ingredients: Salicylic Acid, Lactic Acid, Tea Tree Leaf, Witch Hazel
Amazon
Pros: Skin-boosting power masks filled with collagen and peptides (a dream)
Helps refresh the under-eye area without that soppy wet feeling
Contains hyaluronic acid, niacinamide and caffeine to hydrate, balance the skin and de-puff Cons: Doesn't adhere to the skin as well as other under-eye patches
As a lover of all things Korean skincare, I knew I would want to walk down the aisle with the COSRX The Peptide Collagen Hydrogel Eye Patches (sorry, fiancè). These are like a double shot of espresso for my under-eyes — without the jitters.
What sets these patches apart is their thoughtful formulation. They're packed with five types of hyaluronic acid to hydrate as well, adenosine to boost elasticity and vitamin B12 to soothe and calm. This potent mix not only revitalizes tired eyes but also brightens and firms the delicate skin around them. While they tend to slide a bit, they're worth picking up and using — especially if your beauty shelf looks like it was just express-shipped from South Korea.
They're enriched with a powerhouse blend of four peptides, collagen, niacinamide and caffeine to tackle puffiness, dark circles and fine lines in one swift swipe. They boast an instant cooling sensation and make my under-eye area feel smoother and more awake after just 10 minutes of use.

And let's talk about value. At $23 for 60 patches, they're an affordable luxury that doesn't skimp on quality. The included spatula ensures hygiene and ease of use. After reviewing the near-entirety of COSRX, these have my seal of approval.
Key ingredients: Collagen, Peptides, Hyaluronic Acid, Niacinamide, Caffeine | Amount of patches: 60 pairs
Amazon
Pros: Delivers dreamy hydration and a glass skin finish
Actually stays put
Layers with other skincare beautifully Cons: Some users may find the recommended time to wear the mask too long, though not a dealbreaker
The Biodance Bio-Collagen Real Deep Mask is a Korean skincare innovation that delivers deep hydration and promotes a radiant complexion. The overnight hydrogel mask features a unique two-part design that allows for a customizable fit, ensuring full facial coverage. Upon application, the mask appears opaque and solidifies into a gel-like texture, gradually becoming transparent as it adheres to the skin overnight. This transformation indicates the absorption of its ingredients, leaving skin feeling plump, smooth and glowing.
'The Bio-Collagen Real Deep Mask has seen explosive sales for two key reasons: (1) its effectiveness, especially for customers who find in-clinic facials costly and time-consuming, this mask delivers comparable results from the comfort of home, and (2) it's visually satisfying and sensorially fun to use,' says Yura Kim, who leads the U.S. business team at Biodance. 'Peeling it off to reveal glowing skin is a joyful moment for many customers,' she added.
Key ingredients: Collagen, Peptides, Ceramides | Quantity: 4 masks per pack
Amazon
Pros: Impurities *visibly* slip away onto your fingertips!
Budget-friendly price point
Nurturing for sensitive skin, all while leaving a healthy glow Cons: May not be the best for acne-prone skin
The ANUA Heartleaf Pore Control Cleansing Oil is a lightweight, hydrophilic cleansing oil designed to effectively remove makeup, sunscreen and impurities without stripping the skin's natural moisture. Infused with heartleaf extract, known for its soothing and anti-inflammatory properties, this cleanser is particularly beneficial for those with sensitive skin. It's the best oil cleanser I tested.
The inclusion of plant-based oils such as jojoba, olive, and grape seed oils further supports skin hydration and balances sebum production. Its gentle yet thorough cleansing action makes it suitable for daily use, even for individuals with rosacea or who are eczema-prone.
As soon as I tried this cleanser, I was floored at its ability to clear clogged pores and reduce the appearance of pesky blemishes. What was extremely revolutionary is how I felt the impurities on my fingertips as they were ridded off my skin. Amazing!
This Korean skincare staple offers a cost-effective solution for those seeking a gentle yet effective cleansing oil. Its non-comedogenic formula ensures it won't clog pores (its key factor), making it a reliable choice for individuals concerned about breakouts. So, whether you'd like to integrate this formula as part of a double cleansing routine or as a standalone cleanser, this product delivers on its promise to cleanse, soothe and balance.
Key ingredients: Heartleaf extract | Fragrance: Has a herbaceous scent from the heartleaf | Who it's good for: Dry or sensitive skin
Amazon
Pros: Doesn't deliver a white cast, making it a great facial sunscreen for darker skin tones, especially
Broad-spectrum formulation to protect against both UVA and UVB rays
Hydrating and especially suitable for dry, sensitive and combination skin types Cons: Doesn't leave the most dewy result, but not a dealbreaker
First things first: facial sunscreen is a class of products you don't have to encourage me to use. If you can see my bathroom vanity drawer, it's like a beach bag exploded — in the best way possible.
But, you shouldn't only use a facial sunscreen before your treks to the sand and ocean. Dermatologists recommend using a facial SPF every day (yes, really) as it has been studied to help prevent skin cancer and also slow down the speed of aging, sagging skin.
I found this Korean sunscreen to be the one I can't stop using. There's no greasy look, no white finish and certainly no clogged pores, the latter a tipping point for me (I'm just a girl who wants sun protection, not visible pores).
It's a hydrating formula, contains a lofty SPF 50+, which receives a stamp of approval among dermatologists who recommend slathering on at least SPF 30. Not only did it address dryness but it also went on baby-smooth and helped create a pleasing blurring effect. When I'm out in the sunshine or otherwise, I don't find it streaking off, either. It also layers beautifully underneath makeup.
Size: 1.6 ounces | Key ingredients: Mineral water, Centella aslatica (for soothing)
Amazon
Pros: Offers a glass skin effect instantaneously
Impressive on dry skin types
Excellent value for the money Cons: May be too goopy and watery for some, though it's buildable
Alas, we've arrived at the star of the show — the COSRX Snail Mucin 96% Power Repairing Essence. It's probably the *lowest price ever*, too. Only $12? I'm there.
If you've heard of only one product from the brand, it's likely this one. This was the first product I ever tried from years ago but, when I picked it up recently, it was just like old times.
This product is some kind of miracle in a bottle, and I don't say that lightly. If there's anything you pick up from this list, let it be this product. It's the ideal serum to dab on after your cleanser and the most direct-hitting glass skin product I've tried from the brand at large.
How I use it: Following my COSRX Advanced Snail Mucin Gel Cleanser, I apply one to two pumps and blend it throughout my face, as you would a moisturizer. I focus extra on the apples of my cheeks and the tip of my nose — the areas where pores tend to be more noticeable on my skin. I use the product twice daily.
Amazon
Pros: The dewiest vitamin C cream I've tested!
Features a unique combination of gel and encapsulated vitamin C beads that make it effective once applied
Feels luxurious, but is less than $25 Cons: Thicker formula may not be everyone's cup of tea
Vitamin C, but make it encapsulated and extra! This brightening powerhouse is like skincare armor against dullness, pollution and general life stress. It's great for anyone battling uneven skin tone, dark spots or just looking to glow harder than their LED mask.
Bonus: it doesn't have that metallic C smell some vitamin creams do. Instead, it smells like your skin's about to have a great day. My jaw actually dropped when I saw the encapsulated vitamin C — it's like a glow bath in a tub.
These tiny vitamin C capsules literally burst when you apply it — so you're getting super fresh, stabilized vitamin C right where you need it. What does that mean for your skin? Brighter tone, faded dark spots and an overall more even, radiant look. The texture is this silky-smooth dream that sinks in fast and has the most unbelievable texture. It boasts a really luxe finish that makes my skin feel instantly more hydrated and awake.
Before and after using the medicube Deep Vita C Capsule Cream.
Victoria Giardina
You'll want to use it twice a day — morning and night — after cleansing and toning, and right before you seal everything in with sunscreen (during the day) or a heavier moisturizer (at night, if you're feeling dry). It layers really well, so you don't have to worry about pilling or product overload. In the morning, the vitamin C gives you an extra layer of protection against pollution and sun damage (don't skip the SPF!). At night, it works with your skin's natural repair process to help you wake up looking brighter and more refreshed.
What makes this cream different is how the vitamin C is stored in those little capsules — it stays potent until the second you apply it, which is a big deal since vitamin C usually breaks down fast. Additionally, it's loaded with skin-soothers like niacinamide and panthenol, so even if your skin tends to be a little reactive, it's pretty gentle. If you're just starting out with vitamin C, try using it once a day for the first few days just to make sure your skin is cool with it. But honestly? It's one of those products that feels fancy, works hard and delivers — which is rare.
Size: 1.94 ounces | Key ingredients: Vitamin C, Niacinamide
