5 Best Korean Vitamin C Serum Picks for 2021

 If there is something I’ve learned it’s that there are only a few things that Korean vitamin c serums can’t do. 

It doesn’t matter how dull your skin is or how many scars or blemishes you have; adding one of these serums to your beauty routine will make things better for you. 

1. SeoulCeuticals Day Glow Serum 

Korean Skin Care K Beauty - 20% Vitamin C Hyaluronic Acid Serum + CE Ferulic Acid Provides Potent Anti Aging, Anti Wrinkle Korean Beauty 1oz

This was my first Korean vitamin C ever, and I think it’s for the same reason many people start with the product. 

The SeoulCeuticals day glow serum is one of the highly-rated Korean vitamin C on Amazon. 

It has over 9k ratings on Amazon, and most of the reviews are positive. And the beauty of it is that people with different skin types have used it and shared their experiences.

This gives you a better understanding of the bad and good of the product. 

So, is the serum worth the hype? Let’s find out. 


One of the greatest features of this product is that it gives you fast results. Not overnight results, but within 3 weeks of using it, your acne should’ve started fading away.

The serum’s active components provide your skin with Vitamin C and hyaluronic acid, hydrate the skin, and facilitate collagen production.

As a result, you get a younger and fresh look since collagen helps with skin tightening and reduces wrinkles’ appearance.

Just in case you didn’t know: Collagen prevents our skin from sagging, giving you that youthful look. And as we age, the collagen production in our body decreases.

The vitamin c which is in the form of ferulic acid, and ascorbic acid also helps protect your skin from free radicals. It also brightens your skin in the process giving your skin a fantastic glow.

If you’re struggling with sunspots, vitamin C will help fade them too. It also has Vitamin E, which prevents further skin breakouts and damage.  

The SeoulCeuticals day glow serum has other ingredients that nourish and hydrate your skin. They include dandelion, aloe vera, dandelion, Gotu kola, and jojoba extracts. 

When it comes to the application, the serum is lightweight, watery, and it’s easily absorbed by the skin. 

It’s comfortable and non-sticky, and it doesn’t add to the oiliness of the oily skins. And for people with dry skin, the hyaluronic helps in attracting and locking in moisture to prevent your skin from cracking. 

For the scent, it has a sweet citrus scent that I find very calming. 

Reduces the appearance of wrinkles, blemishes, and sunspots You need sunscreen when going out. Read our guide for the best Korean sunscreen for oily skin.
It’s good for all skin types Very thin, not as thick as other serums (some users complain about this)
It has a sweet citric smell 
It locks in the skin moisture, preventing your skin from drying up
It keeps the skin hydrated all-day 
It prevents skin damage 

Who needs this Korean vitamin C serum? 

This Korean vitamin C is for everyone. It keeps the skin hydrated without making it excessively oily. 

It’s also great for people with skin breakouts, sunburns, and blemishes, as it corrects all this.

2. [KLAIRS] Freshly Juiced Vitamin Drop 

Dear, Klairs Freshly Juiced Vitamin Drop 35mlimage 8802493 14090200

If you’re a fan of Korean products, you’ve come along the KLAIRS somewhere along the way. 

KLAIRS is known for its amazing beauty products; I’ve used their primer, and from the reviews, I can tell their vitamin c serum is equally good. 

But before we approve it, let’s see its features, pros, and cons. 

Let’s get into it. 

Features & Attributes

If you’re just getting started with vitamin c serums, it’s best to start with one with a low vitamin c concentration. And KLAIRS gives you that opportunity because it only has a 5% vitamin c concentration. 

Does that mean that it’s less efficient? Absolutely not; in fact, for some users like Elisa, less is more. See what she says.

If you have sensitive skin, then you’ve got nothing to worry about. Klairs serum is safe and non-irritating.

This is because it contains Scutellaria baicalensis root extract and Centella Asiatica extract that soothes any irritation. 

Like Elisa mentioned above, you may feel some warmth after application, but it’s nothing to be concerned about. 

The product improves your skin tone by getting rid of acne, spots and reducing large pores’ appearance. 

The vitamin C in the product is in the form of Ascorbic Acid derived from Yuja and grapefruits. It also has a little bit of sodium ascorbyl phosphate.

KLAIR serum also has excellent hydrating properties because it contains butylene glycol and sodium hyaluronate. 

If you’re vegan, you’ll be glad to know that this product is cruelty-free and contains no alcohol, parabens, and colorant. 

It’s unscented It soothes irritated skin  It has a small shelf-life (2 months)
It improves discoloration It’s not very good for oily skins
It’s a vegan and non-oily formula 
It leaves your skin glowing
It clears acne 

Who needs this vitamin C Serum?

Although it works well for all skin types, it’s best for people with dry skin. I also recommend this product to people who are just testing the vitamin C serum waters for the first time.

DERMALOGY by NEOGENLAB Vitamin C Serum 22% with Pure Ascorbic Acid,vitamin complex (Vitamin E, Vitamin B5) and Niacinamide -1.12 fl oz.

Neogen is another household name in Korean beauty products. In my research, I’ve found that the Neogen brand always favors people with acne-prone skin.

This Korean vitamin C also stops further damage, nourishes your skin, and keeps it hydrated thanks to Panthenol (Vitamin B3) and Tocopherol (Vitamin E). 

The combination of Vitamin E, C, and B leaves your skin smooth and glowing after application.
