The 12 Best Korean Serums for Smooth, Radiant Skin
These expert-recommended formulas are skin saviors.
Even if you already have the skin care basics (cleanser, moisturizer, sunscreen) down, you might still feel like you’re missing something from your routine. Maybe you’re bothered by hyperpigmentation left over from breakouts. Perhaps you’re plagued with clogged pores, or you might be starting to get concerned about the wrinkles and fine lines forming on your skin. In terms of skin care, serums are the best way to address those certain issues.
“Serums are lightweight skin care products that are applied after cleansing and toning and before moisturizing,” explains Dr. Y. Claire Chang, a board-certified dermatologist at UnionDerm in New York City. “Serums contain a high concentration of active ingredients that may address specific skin concerns, like pigmentation, hydration, uneven texture, or skin aging. They are easy to layer onto your skin care routine and allow you to customize your skin care routine to specifically suit your skin’s needs.” And of all the serums on the market, Korean serums have some of the most sophisticated and efficacious formulas—usually at a bargain, too.
Our top picks for the best Korean serums of 2024
Although Korean and Western formulas increasingly have more in common, there are some vital differences. “The Korean skin care philosophy focuses on long-term benefits and being gentle to skin versus harsh, overnight results that can result in irritation,” says Alicia Yoon, the founder of Peach & Lily. Korean skin care brands are constantly innovating and improving upon their products at breakneck speed, thanks to the country’s extremely competitive market. While the formulas still contain actives, they also have other soothing and hydrating ingredients that prevent damage or irritation. Plus there’s truly a Korean serum for pretty much every skin concern out there.
In order to conjure up this list of the 12 best Korean serums you can get delivered straight to your door, we spoke to the above K-beauty experts for their top picks, tested some ourselves, and read through countless customer reviews. Clear, dewy skin, here you come!
Pros
- Deeply hydrating
Cons
- Can feel sticky
This is the OG snail mucin essence that kick-started the skin care world’s obsession with snail mucin. The lightweight formula hydrates and soothes while also speeding up the skin’s healing process. “I use it similar to a serum for an extra boost of hydration, especially in the winter months,” shares Dr. Chang.
Key ingredient: Snail mucin
Size: 3.38 fl. oz.
Amazon rating: 4.6/5 stars
An ELLE editor says: “What can I say about this product that hasn’t already been said? When I press this serum into my skin, it feels like I’m giving it a drink of water; afterward, my face feels plumper, smoother, and happier. I also have sensitive skin, and it’s never caused a single flare-up. Instead, it helps to soothe my redness or any breakouts I have going on at the time. If you still haven’t tried it yet, I think it’s time for you to take the leap.”—Carol Lee, ELLE.com associate beauty e-commerce writer
Sulwhasoo Concentrated Ginseng Renewing Serum
Pros
- Makes skin feel softer
Cons
- May take time to see results
“The Sulwhasoo Concentrated Ginseng Renewing Serum is formulated with two anti-aging ingredients, ginsenomics and ginseng retinol, which have antioxidant and anti-aging properties to improve fine lines and skin firmness,” says Dr. Chang. Reviewers report seeing smoother, softer skin after just a few weeks.
Key ingredients: Ginseng, retinol, hyaluronic acid
Size: 1.69 fl. oz.
Sulwhasoo rating: 4.8/5 stars
A Sulwhasoo reviewer says: “This is a premium-quality serum that I use every other night. Just a dot on the forehead, a dot on both cheeks, and two dots on my neck. It has kept my Gen X skin feeling like I’m Gen Z. I’ve been mistaken for 20 years younger all the time. I don’t even wear makeup, and it’s because of this serum. It sinks in my skin—doesn’t just sit there. Although it is pricey, it is a really good value for your money because your face is worth it.”
Acwell Licorice pH Balancing Advanced Facial Serum Ampoule
Pros
- Free of sensitizing ingredients like artificial colors and essential oils
Cons
- Can feel sticky
According to Dr. Chang, this product was created “to help brighten dull skin and even out complexion.” The antioxidant-rich serum accomplishes its mission with brightening and hydrating ingredients like licorice root extract, niacinamide, and glutathione.
Key ingredients: Licorice water, niacinamide, glutathione, vitamin E
Size: 1.01 fl. oz.
Amazon rating: 4.4/5 stars
An Amazon reviewer says: “I have been using this product for several years now, and I absolutely love it! It keeps my skin hydrated, and I think it’s comparable to a lot of the expensive skin care out there! I have very sensitive skin, and this doesn’t irritate it.”
Peach Slices Snail Rescue Intensive Serum
Pros
- Sensitive-skin friendly
Cons
- May not feel hydrating enough for dry skin types
Yoon recommends this serum for combination skin or “anyone looking to visibly clear, brighten and hydrate skin without heaviness or irritation,” she says. The snail mucin, cica, and pine bark work hand in hand to hydrate and heal the skin, clearing hyperpigmentation, breakouts, and texture in the process.
Key ingredients: Cica, snail mucin
Size: 1.01 fl. oz.
Peach & Lily rating: 4.8/5 stars
A Peach & Lily reviewer says: “Purchased for my daughter after complaints of not being able to find a consistent routine or product that works for her allergy-prone skin and sensitivity. After making the switch, there has been no turning back. Her skin has never looked better. Even skin tone that is not affected when she has a flare up.”
Pros
- Absorbs quickly
Cons
- May take time to see results
Beauty of Joseon Revive Eye Serum is the ultimate product for warding off signs of aging around the eyes. The formula features a trifecta of powerful ingredients: Ginseng to protect against damaging free radicals, retinal to reduce the appearance of wrinkles, and niacinamide to brighten any darkness in the area. “It blends in nicely with the skin and keeps the skin looking smooth and hydrated,” says Dr. Chang.
Key ingredients: Retinal, ginseng extract, niacinamide
Size: 1 fl. oz.
Amazon rating: 4.3/5 stars
An Amazon reviewer says: “The Beauty of Joseon Revive Eye Serum has become a staple in my skin care routine. It’s lightweight, yet incredibly hydrating, and absorbs quickly without any greasiness. I’ve noticed my under-eye area looks brighter and feels much smoother after consistent use. I’ve seen a reduction in puffiness and fine lines. It works great under makeup too, without causing any creasing or heaviness.”
Pros
- Suitable for sensitive skin
Cons
- Full results take time
If you want to use a retinol serum but haven’t found a formula your skin tolerates, you might want to try a Korean one. “This is a gentle yet powerful retinol serum that contains four types of retinol and retinoid to help fight signs of aging,” explains Dr. Chang. “It also contains lactobacillus ferment lysate to strengthen the skin’s barrier.”
Key ingredients: Pure retinol, encapsulated retinol, granactive retinoid, bio-seletinoid (retinoid), lactobacillus ferment lysate
Size: 1.01 fl. oz.
Amazon rating: 4.3/5 stars
An Amazon reviewer says: “I recently purchased the Iope Retinol Serum on Amazon Prime Day, and I’m thrilled with the results! My skin feels smoother and more radiant after just a few weeks of use. The texture is lightweight and absorbs quickly without any irritation. I love how it targets fine lines and improves overall tone. Definitely a game-changer for my skincare routine. Highly recommend!”
Some By Mi AHA BHA PHA 30 Days Miracle Serum
Pros
- Helps clear breakouts
- Offers gentle exfoliation
Cons
- May not be suitable for very sensitive skin
“Some By Mi AHA-BHA-PHA 30 Days Miracle Serum is a powerful combination of three chemical exfoliants that help exfoliate, brighten the skin, and improve skin texture,” says Dr. Chang. Because it also contains centella asiatica, however, it’s less likely to lead to irritation and inflammation—two things that can cause even more acne and uneven texture.
Key ingredients: Tea tree water extract, centella asiatica, AHAs, BHAs, PHAs
Size: 1.69 fl. oz.
Amazon rating: 4.6/5 stars
An Amazon reviewer says: “Definitely a holy grail for me. I have dry, sensitive skin, and this doesn’t irritate me or cause me to break out. It lasts well over a month for me, and I wash my face and use it twice a day. It’s helped with my breakouts, dryness, and redness.”
Pros
- A little goes a long way
Cons
- Contains fragrance
According to Yoon, this “is a classic K-beauty serum that leverages Korean herbal ingredients to visibly minimize pores and oil production.” Although it controls sebum, it won’t dehydrate or strip your skin (which can sometimes cause your skin to overcompensate with even more excess oil).
Key ingredients: Ginger root extract, thyme extract
Size: 1.7 fl. oz.
Peach & Lily rating: 4.6/5 stars
A Peach & Lily reviewer says: “I’ve tried so many things over the years to help my skin. I’m so oily and always broke out as a child. This serum is so silky-smooth and rubs on effortlessly. I’ve noticed a huge difference in the oil, and it is helping with the pores. Love this product. I think I’ve actually purchased it about six times so far and plan to keep using it. Highly recommend this.”
Pros
- Lightweight texture
Cons
- Some may dislike scent
Facial oils can feel overly heavy and greasy on the skin. However, this oil-serum hybrid sinks in super quickly as it quenches dry skin. “It combines an exclusive white lotus extract from Jeju Island, packed with antioxidants and flavonoids, and a beautiful oil blend to deeply hydrate and moisturize while visibly brightening and firming skin,” says Yoon.
Key ingredients: Camellia extract, Jeju white lotus extract, lemon fruit oil
Size: 1.7 fl. oz.
Peach & Lily rating: 4.5/5 stars
A Peach & Lily reviewer says: “This serum has a very liquid, essence-like texture, so I was a bit skeptical. But once you rub your hands together and press it in your skin, you feel the wonderful, cushiony oil. This keeps my dry-ish skin nicely plump and hydrated and smells very nice. My skin is also a bit finicky and sensitive, but this is not irritating or making my skin red at all.”
Pros
- Works well under makeup
Cons
- Difficult to get the last bit of product out
“The HaruHaru Black Rice Hyaluronic Ampoule leverages the visibly brightening, renewing and hydrating properties of black rice to rejuvenate skin and leave a radiant glow,” says Yoon. Other notable ingredients include fine line-reducing adenosine and hydrating hyaluronic acid.
Key ingredients: Rice 2GF, adenosine, hyaluronic acid
Size: 1 fl. oz.
Amazon rating: 4.3/5 stars
An Amazon reviewer says: “I have been using this serum for a few weeks, and the results I have seen have been wonderful. The serum is thicker than most watery serums, moist and not tacky. I use it on a face that has been spritzed with a moisturizing toner, and the glow is real. Give it a go if you are looking for a serum that delivers moisture, comfort, and visible results. I’m a registered esthetician, and I would recommend this product to my friends and clients.”
Klairs Freshly Juiced Vitamin C Drop
Pros
- Provides visible changes
Cons
- Results take time
When you have extremely sensitive skin, even vitamin Cs can sting and irritate. Klairs Freshly Juiced Vitamin C Drop contains enough of the brightening antioxidant to fade and prevent hyperpigmentation, but it also boasts centella asiatica, an anti-inflammatory ingredient I love because it always manages to soothe my skin.
Key ingredients: Ascorbic acid (vitamin C), centella asiatica extract, yuja fruit extract
Size: 1.18 fl. oz.
Soko Glam rating: 4.2/5 stars
A Soko Glam reviewer says: “I’ve tried many vitamin C serums and I always, always end up going back to this amazing potion in a bottle. I get so many compliments, and people always assume I just had a facial. It’s lightweight, absorbs into your skin well, and does not leave a greasy feel.”
Rovectin Cica Care Clearing Ampoule
Pros
- Works well under makeup
Cons
- May not be suitable for very oily skin
This serum is bursting with a whopping 73 percent concentration of centella asiatica, an herb used to calm irritation and fade scars. Calamine, another major player in this formula, also helps to gently soothe the skin.
Key ingredients: Calamine, cica, centella asiatica, damask rose
Size: 1 fl. oz.
Amazon rating: 3.9/5 stars
An Amazon reviewer says: “This ampoule helps to calm my skin when it’s red or sensitive. It’s kind of thick, but it goes on smoothly, and it makes my skin feel much better and hydrated.”

Can you apply serums both morning and night?
Dr. Chang says yes, and Yoon says that “typically, serums are for at least once daily use, and often for morning and evening use every day.” But there are some caveats—it all depends on the formula and the ingredients in it. For example, you might want to keep retinol use to evenings, since the ingredient can make you more sensitive to the sun. On the other hand, vitamin C is best suited for mornings, since applying that ingredient in conjunction with your SPF can actually bolster sun protection.
How should you apply serums?
First, make sure your skin is clean but not completely dry. “Serums tend to absorb better on damp skin,” Yoon says. You can also apply “a hydrating essence before your serum to help your treatment serums work harder for your skin. Only caveat is for retinoids and other active ingredients where more may not be more for your skin,” she adds.
After applying the serum, Dr. Chang emphasizes that you should let it dry down for about a minute before going in with the next steps of your routine. Additionally, “be consistent and patient as it takes time (up to six to 12 weeks) to see results,” she says.
