10 Best Korean Serums

Even better, these serums are incredibly affordable, with most being available at drugstore prices.

Korean skincare brands formulate their products to appeal to a variety of skin types with various skin concerns, so while most of these serums will work for all skin types, each serum in this list will be noted BEST FOR specific skin types and/or skin concerns.

Now, let’s take a look at the best Korean serums!

1. Klairs Rich Moist Soothing Serum

BEST FOR: Dehydrated and dry skin, irritated skin, damaged skin, sensitive skin

Klairs Rich Moist Soothing Serum

Klairs Rich Moist Soothing Serum is a savior for dry skin as it replenishes the skin with multiple hydrating complexes.

The serum is chock full of soothing and moisturizing ingredients and plant extracts like celery, carrot root, and broccoli extracts, in a lightweight easily absorbed formula.

Sodium hyaluronate, the salt form of hyaluronic acid, is the second most concentrated ingredient in this serum. Sodium hyaluronate has a smaller molecular weight than hyaluronic acid, so it can penetrate the skin more deeply to deliver long-lasting hydration.

There are multiple soothing ingredients in this hydrating serum, such as reparative licorice root extract, panthenol, beta-glucan, Aloe barbadensis leaf extract.

Centella asiatica extract, Portulaca oleracea (purslane) extract, and Scutellaria baicalensis (skullcap) root extract, not only soothe the skin but are also skin-protective antioxidants.

Vitamin C derivative sodium ascorbyl phosphate and niacinamide brighten the skin by inhibiting melanin production and improving skin tone. Amino acids arginine and proline are building blocks of skin-firming collagen and provide skin-strengthening benefits.

All of these ingredients work together to soothe, hydrate, and brighten dry skin in a silky smooth hydrating serum. The generous 2.7 oz bottle makes it one of the most affordable Korean serums on this list.

Please note that the serum has been recently reformulated to remove essential oils to make this serum suitable for all skin types, including sensitive skin.

2. Benton Snail Bee Ultimate Serum

BEST FOR: aging skin, dull, uneven skin tone, acne scars, hyperpigmentation

Benton Snail Bee Ultimate Serum

Tea tree leaf water calms stressed, problem skin while aloe vera (powder and extract) soothes the skin and supports a healthy skin barrier.

Niacinamide and adenosine target wrinkles and help improve skin elasticity. Niacinamide also brightens dull skin tone and has sebum balancing benefits for the skin.

Salix alba (willow) bark extract has anti-inflammatory and antioxidant properties. It gently exfoliates the skin by lifting away dead skin cells to reveal brighter-looking skin with improved skin texture.

Bee venom can regenerate the skin and has anti-inflammatory benefits that can help heal the skin and reduce redness. It can even reduce the appearance of wrinkles.

This multifunctional serum has a light texture that quickly absorbs into the skin without feeling heavy or greasy. It has a slightly acidic pH similar to our skin, minimizing irritation. A few drops of this serum can even be mixed with your foundation for a complexion boost.

This cult-favorite Korean vitamin C serum contains 5% pure vitamin C to brighten the skin and even out skin tone while reducing hyperpigmentation and dark spots. Vitamin C is a potent antioxidant that helps to reduce the look of fine lines while keeping the skin firm.

Vitamin C at higher concentrations can irritate the skin, but Klairs has formulated their vitamin C serum at a low 5% and added Centella asiatica extract to help soothe and calm the skin.

This makes the serum suitable for sensitive skin types, but please note that the serum contains essential oils and citrus fruit extracts, so be sure to patch test before using it (and any new skincare product) for the first time.

Innisfree Intensive Hydrating Serum with Green Tea Seed is a lightweight serum formulated with Green Tea Tri-biotics, niacinamide, hyaluronic acid, and a host of other active ingredients to hydrate, protect, and moisturize the skin.

The Green Tea Tri-biotics formula is a fermented probiotics dissolution combining three ingredients: prebiotics (trehalose), Jeju green tea (lactobacillus ferment lysate), and postbiotics (lactic acid). This complex supports the skin’s ecosystem for a healthy barrier function.

Green tea extracts (green tea water and green tea oil) are included in the formula to soothe, protect and brighten the skin. The green tea is sourced from a USDA-organic farm on Jeju Island in South Korea. The soil there is rich in volcanic ash and minerals, resulting in a unique green tea rich in 16 moisturizing amino acids.

There are five different molecular weights of hyaluronic acid in the serum. This variety of weights allows the hyaluronic acid to penetrate deeply into the skin at different layers for long-lasting hydration.

The serum also contains niacinamide, an ingredient that brightens the skin, improves uneven skin tone, and reduces the appearance of fine lines and wrinkles. Betaine, a plant-derived amino acid, helps lock in moisture, while squalane provides lightweight moisture.

The high concentration of tea tree extract in this serum is anti-inflammatory, antimicrobial, and healing. It helps to reduce acne breakouts, heal blemishes, and calm redness and inflammation.

COSRX Hydrium Triple Hyaluronic Moisture Ampoule

COSRX Hydrium Triple Hyaluronic Moisture Ampoule quenches thirsty, dry, and dehydrated skin types with three types of hyaluronic acid and panthenol (pro-vitamin B5).

The serum keeps skin soft and supple all day without leaving it feeling greasy.

Low-weight hyaluronic acid pulls in moisture, while medium-weight hyaluronic acid provides below the surface hydration. High-weight molecular hyaluronic acid forms a protective barrier on the skin to prevent moisture loss. The three weights provide extended hydration that can penetrate different layers of the skin.

Panthenol is a humectant that helps attract and retain moisture and offers anti-inflammatory skin benefits.

This Korean skincare product has a short ingredient list that minimizes the potential for skin irritation. It has a super-thin texture and sinks in quickly for long-lasting hydration. Skin is plump and hydrated for more youthful-looking skin.

Sodium hyaluronate, the salt form of hyaluronic acid, is a powerful moisture-binding ingredient that acts like a sponge and pulls water into the skin. This makes it ideal for those with dehydrated or dry skin. It helps to hydrate and plump the skin, reducing the appearance of fine lines and wrinkles.

Rice ferment filtrate (sake) is an active ingredient popular in Asian skincare products that is rich in amino acids, vitamins, and minerals. It works as an astringent to help reduce the look of pores.

Sake also contains antioxidants that protect the skin while it improves skin elasticity for plumper, smoother skin.

How To Use A Korean Serum

When using a Korean serum, be sure to apply it after cleansing and toning but before applying your moisturizer (and sunscreen in your morning skincare routine). If you use a water-based serum, apply it before your oil-based products.

Start with 2-3 drops of serum and massage it into your skin until it is fully absorbed. You can increase the amount of serum you use as needed.

Korean serums are often highly concentrated, so a little goes a long way. Be sure to follow the directions on the packaging for the best results.

Patch test the serum on a small area of skin before using it for the first time, especially if you have sensitive skin.

How To Choose A Serum For Your Skin Type

When choosing a serum, it is important to consider your skin type and what ingredients best address your specific concerns. The following Korean serum ingredients are helpful for the following skin types and skin concerns:

  • Dry Skin: hyaluronic acid, panthenol, or betaine
  • Combination Skin: niacinamide, hyaluronic acid
  • Oily Skin: BHAs (beta hydroxy acids) like salicylic acid, niacinamide
  • Acne Prone Skin: salicylic acid (BHA), AHAs, niacinamide, retinol, green tea, or tea tree oil
  • Sensitive Skin: snail mucin, Centella asiatica extract, aloe, allantoin, or green tea
  • Aging Skin: AHAs, peptides, propolis, retinol, or adenosine
  • Hyperpigmentation, Dark Spots, and Uneven Skin Tone: vitamin C, licorice root extract, azelalic acid, or niacinamide

Once you have determined your skin concerns, take a look at the ingredients list to see which serums will address those concerns. Avoid any ingredients that may irritate your skin (especially if you have sensitive skin), such as essential oils or fragrances.
