Top 9 Korean Vitamin C Serums Worth the Buy

Hundreds of brands in South Korea have their version of vitamin C serums.

But don’t fret; we’ve narrowed down the options to the nine top available ones you can buy now! We’ve also categorized them according to which skin types they suit.

Vitamin C Serums for Normal, Combination, and Oily Skin

Neogenlab Dermalogy Real Vita C Serum

We love this lightweight yet potent product because it ensures you can get as many skin benefits as you can from using vitamin C.

Key benefits: Combats signs of aging; evens skin tone; brightens dull and pigmented skin


  • Has sodium ascorbyl phosphate
  • Comes with citrus fruit extracts
  • Great for oily and combination skin

A very potent formulation for a vitamin c serum, but it’s lightweight and highly effective!

Looking for a potent vitamin C serum? Neogenlab’s Dermalogy Real Vita C Serum is for you! 

Many women have used this to achieve the bright and glowing skin they have dreamed of. 

Its primary ingredient is 10% sodium ascorbyl phosphate, a stable source of vitamin C.

It also comes with 12% acerola-plex, which features citrus fruit extracts rich in vitamin C, bumping up the concentration to 22%.

As such, the serum is extremely potent. It brightens the skin, minimizes pores, reduces the appearance of hyperpigmentation, and gives your complexion a youthful glow.

It has a lightweight water-based formula, perfect for people with normal, oily, combination, and acne-prone skin. 

However, since it’s super strong, it’s not friendly to beginners or those with sensitive skin. It’s also pricier compared to other products, so only buy this if you’re sure your skin can handle it.

SeoulCeuticals Day Glow Serum

We recommend this serum because it contains plenty of antioxidants!

Key benefits: Reduces wrinkles and fine lines; boosts collagen production; brightens and hydrates


  • Highly potent with 20% sodium ascorbyl phosphate
  • Formulated with added antioxidants
  • Has hyaluronic acid to help with skin hydration

Highly potent and hydrating, SeoulCeuticals’ Day Glow Serum helps you attain that radiant glow!

What’s not to love about the SeoulCeuticals Day Glow Serum?

With a 20% concentration of sodium ascorbyl phosphate, this serum combats signs of aging.

On top of that, it has hyaluronic acid, which hydrates and plumps up the skin.

This means it can fade age spots, smooth out wrinkles and fine lines, and minimize the appearance of your pores.

So if you need a Korean vitamin C serum with impressive brightening and hydrating properties, this one’s for you.

But note that this product’s Vitamin C concentration is on the higher end, so it might irritate sensitive skin. 

By Wishtrend’s Pure Vitamin C Advanced Serum

We love this highly potent serum as it has added ingredients that help in keeping your skin hydrated and protected.

Key benefits: Brightens skin; anti-aging; anti-inflammatory; hydrating

Its high concentration of pure vitamin C powerfully delivers anti-aging benefits, including evening out the skin tone, fading hyperpigmentation, and revitalizing dull skin.

However, this serum is not for beginners. Since it uses ascorbic acid, it is more unstable and has a shorter shelf life than other entries in this list.

Pros and Cons of Vitamin C Serums

Excited to try one of the products from our list of the top Korean vitamin C serums? Great!

But before you add this serum to your arsenal, you must first know what you’re getting into.

Read on to learn about vitamin C’s pros and cons to help you maximize its benefits and avoid potential drawbacks.

Pros of Vitamin C Serums

Fights and Prevents Signs of Aging

Clinical studies have shown that vitamin C helps slow down skin aging.

Using its antioxidant properties, it protects the skin from oxidative damage, which results from consistent UV exposure and leads to the formation of wrinkles, fine lines, and age spots.

It also boosts collagen production, helping repair damaged skin and allowing it to stay elastic, supple, and strong.

Evens Out Pigmentation

It’s widely known that vitamin C helps eliminate annoying dark spots.

This is because it helps control melanin overproduction, helping treat and prevent hyperpigmentation.

Boosts the Effectiveness of Your Sunscreen

Vitamin C can work together with your sunscreen to minimize the redness and damage your skin can get from the sun’s UV rays.

Quick Tip

Use a vitamin C serum before putting on sunscreen to maximize your UV protection throughout the day!

Cons of Vitamin C Serums

Can Be Unstable

Pure vitamin C (ascorbic acid) can be unstable, meaning exposure to heat, light, and air can cause it to oxidize.
When vitamin C oxidizes, it loses its effectiveness, becomes useless, and sometimes even changes its color. In some cases, oxidized vitamin C can stain or irritate your skin. 

This is why many Korean skincare brands mix pure vitamin C with ingredients like vitamin E and package their serums in tinted bottles to prevent oxidation.

Some also use more stable forms or derivatives of vitamin C, such as sodium ascorbyl phosphate.

Quick Tip

Store your Korean vitamin C serum in a cool place away from direct light.

Does Not Mix Well With Some Skincare Ingredients

Mixing vitamin C with other acids or ingredients that operate at an alkaline pH level can irritate your skin instead of improving it.

These include retinol and AHAs like glycolic acid and lactic acid.

Quick Tip

If you want to have both retinol and vitamin C in your skincare routine, use retinol at night and vitamin C in the morning. This will prevent them from interacting while ensuring you get both ingredients’ benefits.
