In this article, we’ll demystify everything about this ingredient, go through a range of products, understand how they work and answer some of the most asked questions about picking hyaluronic acid as a skincare ingredient.

What is hyaluronic acid?

Let’s get one thing out in the open: Hyaluronic acid is already produced by our bodies, but as you start ageing,  its levels start to decline in our skin, thus leading to drier, duller skin. 

No wonder you need a replenisher – and hyaluronic acid serums are just right for the job. In simple words, hyaluronic acid does the task of boosting firmness in the skin, slowing down future fine lines and wrinkles. 

If you’re looking for immediate results, you’ll find those too: Wake up with a dewy texture and glowing skin every day.

Hyaluronic acid in reality is one of the only few skincare ingredients that aren’t too good to be true. It isn’t a wonder molecule, but it does everything it claims. 

You must’ve heard this a lot — 

Hyaluronic acid hydrates your skin. But do you know how that works?

There have been bold claims about how hyaluronic acid can hold about 1000 times the weight in water, and well, it is true. Hyaluronic acid is formulated and used to take care of your epidermis — the outer layer of your skin. The acid can work in two ways, either it attracts water molecules from the environment around you or from the dermis, which is the layer of skin beneath the epidermis.

But a lot of other factors go into consideration — the humidity around you, pH, osmotic gradient etc.

Benefits of hyaluronic acid serum

Hyaluronic acid’s water-loving ability paves way for numerous benefits that can completely change the way your skin looks in the long run. Here are some of them —

  • This agent seeps into the skin and accelerates the process of healing wounds in the skin, also aids the process of growth of new skin. If perhaps, your skin is already healthy, it aids more in the maintenance of the epidermis, which ultimately deals with new cell growth.
  • Hyaluronic acid phenomenally heals wounds with its anti-inflammatory properties. Its lighter molecular weight actually helps the immune response, thus healing wounds thoroughly. And you know serums are a highly concentrated form of skincare ingredients. So you can imagine now what a few drops of Korean hyaluronic acid serum can do to your face.
  • There have been proven studies that prove that a good hyaluronic acid serum helps the appearance of visible wrinkles, fine lines by improving the skin’s elasticity.

How to choose the best Korean hyaluronic acid serum?

In my reviews below,  I think I have done justice by explaining what each star ingredient does for your face. I personally have a combination skin type, leaning towards dry. So make sure to pick one that works out best for you. 

Our team skincare experts at Best Korean Products reviewed these Korean hyaluronic acid serums based on their hydration power, moisture protection and post-applying comfort on the skin. 

I’d urge you to take extensive notes of your skin, do a patch test if you must and decide what is the best Korean hyaluronic acid serum for your skin.

Eradicating Confusion on hyaluronic acids

Not all hyaluronic acids are called the same. It is possible that you’ll come across the name hyaluronan or sodium hyaluronate or even potassium hyaluronate — they’re all from the same family.

If your humectant serum has no additional occlusives or emollients, make sure to complete your skincare routine with ingredients that have occlusive properties. Ensuring that means minimizing the possibilities of water loss from your skin.

You see, hyaluronic acid is a humectant. 

Humectants are only responsible for drawing water to the skin and keeping those water molecules bound. It is a good occlusive that helps you fill in the dry areas and create a film on top of the skin that prevents water loss. Adding something with squalene or mineral oil in your skincare routine should do the trick.

Seoul Ceuticals Day Glow Serum – Vitamin C Hyaluronic Acid Serum

Seoul Ceuticals Day Glow Serum

As someone who has tried and reviewed a number of Korean hyaluronic acid serums, I must say that this is the only serum that has 98% natural ingredients and 72% organic ingredients. The natural ingredients in this serum wanted me to purchase it and try to find if it was effective as the rest of the serums.

To my surprise, it really did serve its purpose. The Seoul Ceuticals Day Glow Serum claimed to provide visible results within 3 weeks of use but I began to see visible results after just 2 weeks. 

The hyaluronic acid deeply moisturized my skin making it appear soft and plump, in fact, I loved to pinch my cheeks often because they were so soft after using this serum.

And not to mention the stubborn acne scars I’ve had for years disappeared gradually as I continued using this serum. I stopped wearing makeup to cover my blemishes after using this serum because it even-toned my overall complexion.

The ingredients in this serum such as Vitamin C, hyaluronic acid, ferulic acid, and d-Alpha Tocopheryl are what contributed to the perfectly smooth and brightening skin. It’s also a beneficial serum for those who have mature skin because the Vitamin C reduces your wrinkles and fine lines in no time. 

It has an amazing, citrusy aroma that just keeps your skin refreshed. The texture is almost like water and absorbs quickly to your skin and deeply hydrates it. The only downside of this serum is the packaging because the dropper doesn’t close properly but performance-wise, this is one of the best Korean hyaluronic acid serums out there.


  • Natural and organic ingredients
  • Suitable for all skin types
  • Deeply hydrates the skin
  • Brightens the skin
  • Reduces aging signs
  • Visible results within 2 weeks


  • Expensive 

Cos De BAHA Pure Hyaluronic Acid Serum

Best Korean Hyaluronic Acid Serum for All Skin Types

I love how simple and uncomplicated this serum was. All it contained was Purified Water, Hyaluronic Acid, 1,2-Hexanediol, which meant I didn not have to worry about any reaction or irritation that could have appeared on my face. 

The inclusion of  1,2-Hexanediol in this duo formula just felt like an additional layer of much needed hydration to my skin. All the dryness and flakiness that seemed to persist was noticeably reduced within just a week’s use. 

If your skin is oily, you might experience some discomfort in terms of feeling the stickiness of the surface of your skin because of its thick consistency.

Additionally, the serum claims to bring the pH level of the skin to a 6.5. My skin did start to feel as if it was reaching a smooth ‘normal’. 

I purchased the 50 ml glass  , and it lasted me about 3 months. For as long as it lasted me, I did not have any complaints. You can also find a larger bottle with a pump style nozzle. 

Because of its consistency, I’d say I only use this serum in my PM routine. The film feels comforting, and it remains true to its job and feels supremely hydrating and plumping. All in all, I think this justifies why this serum made it to the list of best Korean hyaluronic acid serums.


  • Contains skin beneficial ingredients 
  • Deeply hydrates the skin
  • Visible results after 1st week of use
  • Balances out the skin PH level
  • Keeps skin plump and soft


  • Not suitable for oily skin
  • Has a thick consistency

Mizon Original Sum Skin Eneronic Hyaluronic Acid 100

Best Korean Hyaluronic Acid Serum for Dry Skin

Can I just start by saying, how cute is the little blue glass bottle? If I’m being completely honest, I may have let the cuteness affect the buying decision. But it’s not all good. The swivel around the cap is plastic which gets stuck sometimes, causing me to drop the bottle. Luckily it didn’t break. 

Let’s talk about the ingredients. I have been going on about Hyaluronic acid and its form — Sodium Hyaluronate. While this serum claims to be hydrating, I think it’s kind of lacking. 

The ceramides in the serum are like fat molecules that help retain the pre existing moisture, which the serum fairly does. 

Tropolone is simply an antibacterial preservative to keep your skin from reacting, whereas the raspberry extracts in the serum act as antioxidants the help your skin further itself away from being prone to damage. 

What adds to the bargain is the texture of the serum. It’s light on the skin and has a silky feeling to it. Your skin can feel slightly sticky right after you apply it, but soon after it dries, the stickiness also disappears.

best korean hyaluronic acid serum for pores

From my experience, I’d call this Korean hyaluronic acid serum more preventative than any action to heal the existing problem. 

Maybe it is slow working — because I only purchased a 30ml bottle and I didn’t see much effects in terms of it affecting the hydration of my skin, but it did start to feel smoother and moisturized. 

Additionally, I did not have any breakouts the entire time I used this hyaluronic acid serum.

During the course of the use of this serum, my skin felt moisturized, but I didn’t get the hydration I wanted, neither did it feel absolutely comfortable to wear during the day. 

For this price, you can get the Elizavecca Milky Piggy Hyaluronic Acid 100% Serum for 5 times the quantity and it’s far more lovely. 


  • Light consistency
  • Attractive packaging
  • Makes skin feel silky
  • Absorbs quickly on the skin


  • Not very hydrating
  • Takes longer to show results

Elizavecca Milky Piggy Hyaluronic Acid 100% Serum

Best Korean Hyaluronic Acid Serum for All Skin Types

I began raving about this even before I started reviewing it, so here goes — 

Technically, this serum has the exact same ingredients as the Cos De BAHA Pure Hyaluronic Acid Serum, but I find it far more effective and even economic. 

The consistency is kind of runny and doesn’t feel heavy on the skin, unlike the Cos De Baha serum. This means that it will work well for people with all skin types. It successfully did a good job of eliminating any dry patches I had on my skin. 

The simplicity of the product makes it targeted towards your skin. Don’t let the piggy in the name scare you away. 

I used it at night, and when I woke up, I was pleasantly surprised with a soft, plump feeling on my skin right after the first use!

Honestly, I’m a bit iffy about ordering large glass bottles, but this came intact and ready for me to use. The heavy frosted glass bottle looks great but can be a bit frustrating if you’re thinking about travelling. 

I’d recommend pouring some from this pour-over bottle into a dropper style bottle if you have one. 

I’d give full marks for everything. Hydration power, ability to moisturize and post-applying feeling. In fact, it is one of the favourite Korean skincare products and definitely one of the best Korean hyaluronic acid serums I have had on my shelves in the years of reviewing that I have done. 


  • Light watery consistency
  • Suitable for all skin types
  • Extremely hydrating
  • Quick absorbing
  • Moisturizes skin deeply
  • Makes skin soft and smooth


  • Packaging isn’t user and travel friendly
  • Quite expensive

Elizavecca Hell Pore Control Hyaluronic acid Serum

Best Korean Hyaluronic Acid Serum for Oily Skin

I clearly liked the Elizavecca Hyaluronic 100 so much so that I bought another one simply to try it out, even though it doesn’t typically suit my skin type. Because who doesn’t want hydration and more control. 

Ah, this serum is packed with goodness. Even though it claims it’s best for oily skin, it suited my skin just fine. Look at the ingredients: Hyaluronic Acid, Niacinamide, Arginine, Adenosine, Allatoin. 

Make sure to cleanse your skin before using this, because the niacinamide will act on your pores to make their appearance smaller. 

I did feel the Allatoin work on my skin as it seeped through and promoted the healing process, moisturized skin and probably rejuvenated my cells from within as it joined hands with our star ingredient hyaluronic acid.

The adenosine acts as an anti-wrinkle agent that helps smoothen out the skin and restore the soothing comfortable feeling. I did feel the serum work its way in to do just that, so I can vouch for it. Arginine on the other hand acts as an antioxidant that helps prevent any breakouts.

I won’t lie, I dropped this bottle twice, but the glass bottle is sturdy enough, phew.  The dropper just exudes ease and convenience in comparison to the one we saw above. When I smeared a few drops on the back of my palm, it didn’t feel runny or thick, it was somewhere in between, like coagulated water.

For oily skin, this is the holy grail, because it doesn’t leave an ounce of stickiness on the skin and is quick drying. For drier skins, you’ll experience dry patches wading away. 

I experienced the hydration and moisturizing effect that it claims. I did feel comfortable enough to layer products on this when I wore it in the day.

Elizavecca Hell Pore Control Hyaluronic acid serum


  • Contains skin beneficial ingredients
  • Deeply hydrates and moisturizes the skin
  • Rejuvenates skin cells
  • Reduces wrinkles and dry patches
  • Prevents breakouts
  • Good-quality packaging
  • Affordable 


  • Only for oily skin

TIAM Hyaluronic Water Plumping Serum

Best Korean Hyaluronic Acid Serum for Damaged Skin

The minimalist in me was really piqued by the packaging, but what’s more impressive, is the combination of ingredients jam-packed in this 40 ml bottle. In my experience, this is a special formulation for those who have dry and damaged skin that is practically dehydrated.

The main claim of this Korean hyaluronic acid serum is to ‘quench the thirst’ of the skin. At the end of the month of my use of this serum, I can satisfactorily say that my thirst has been quenched. 

In fact, my skin felt supple and bouncy too. A major contribution to that is from the Hyaluronic Acid Complex (HA-6) present in the formulation. 

This combination provides a packed experience to the skin. Right from it receiving intense doses of hydration to maintaining it throughout the day on every layer of the skin. The moisture is locked in from one of the complexes and works to enhance the freshness in your look!

At the end of my month with this serum, I felt the lotus extract working its magic and enhancing the elasticity of my skin. Panthenol, on the other hand, worked to enhance my skin’s barrier and kept it feeling soothing. 

Consistency wise, you could say it was leaning towards milky thick. It isn’t fast-drying, so it can feel a bit heavy on the skin, especially if you’re planning to layer it under your makeup for the day. 

My advice would be to rub it in a little bit so it speeds up the process. Or just be patient and give it a few minutes to seep into your skin! 

Hydration and moisture wise, this serum is excellent. When it comes to comfort on the other hand, other than the waiting period for it to dry, it is manageable. 


  • Extremely hydrating properties
  • Reduces dry patches instantly
  • Locks the moisture within
  • Improves skin texture
  • Maintains skin elasticity


  • Thick and heavy texture
  • Takes time to dry

The Face Shop White Seed Brightening Serum

how to use korean hyaluronic serum

I was looking for a brightening serum that can fade stubborn blemishes and marks I have been carrying for so long, this product  is honestly a life saviour. 

The White Seed Brightening Serum by The Face Shop contains white lupin seed removing substances, which is known for its regular skin lighting up properties. It likewise contains white daisy bloom extricates that decrease bluntness and deliberately made the skin appear brilliant and softer in just 15 days of usage. 

An unique botanical skincare item that very well moisturized my skin while helping in deeply improving the skin texture and clarity from pores. The serum is very thin and light, not thick and sinks into the skin quickly. 

Been using it every night for a week and haven’t seen any differences in my skin but I like the smell, which is a tant bit like floral tea and how quickly it absorbs does not leave my face oily or greasy and gives a defined glow at first instance itself. The serum penetrates deep into the skin and helps in even out the skin tone, helping in treating dark spots.

Also, the one of a kind characteristic that intrigued me the most was the serum being without paraben with No counterfeit tones and No creature fixings. It doesn’t have any mineral oils in it and is a finished Talc free item.

It is 50 mL so it won’t last you very long but my bumpy dry skin is a lot smoother and softer now. So it is definitely worth it to continue purchasing this highly recommended whitening serum. I am on my second bottle now and I love how it makes my skin so healthy and refreshing. Can’t imagine a day without it.


  • Hydrating 
  • Moisturising
  • No harmful chemicals
  • Comes in Hygienic pump packaging


  • Not effective for acne prone areas

Dear Klairs Rich Moist Soothing Serum

image 20

The Klairs Rich Moist Soothing Serum hydrates and relaxes the skin. It’s liberated from everything: ethanol, sans paraben, silicon, steroid, fake colorings, and counterfeit scents. 

This serum contains more modest particles with higher concentrates of advantageous fixings contrasted with customary creams. The serum  is simply implanted with higher concentrates of dynamic fixings that can enter further into the skin, conveying more designated results. 

This Klairs Rich Moist Soothing Serum is a saturated serum that completely hydrates profoundly inside the skin and I have been utilizing it for a brief time frame and it has been giving incredible outcomes in a brief time frame.

 It makes my skin milder and renewed with dampness, and keeps the skin brilliant and shining for the duration of the day which is perfect. With its cooling highlights, it brings down the surface temperature as it profoundly hydrates inside the skin.

This one is probably the most liquidy I’ve ever used. It has absolutely no scent which is nice because perfumes can often sting, and it’s definitely moisturizing. The bottle is pretty big for a serum, so it will most likely last me a long time. This experience of using this product was definitely impressive!

While applying the serum goes on really Wetish but then quickly dries into completely smooth. Once applied and patted on, it leaves a slightly tacky feeling but that soon goes away when I apply a moisturiser on top.

  • Lightweight
  • Not too sticky
  • Fast absorbing
  • Smells amazing
  • Extremely hydrating
  • Effective after one night
  • Works great on acne prone areas


  • Not effective for sensitive skin type

Best Korean Hyaluronic Acid Serum: FAQs

How to include Korean hyaluronic acid in the skincare routine?

The one most important rule of layering skincare is putting the lightest product first and following it by heavier, denser products. Another thing to remember is the products you’re using.
People generally use hyaluronic acid that is either in serums and moisturizers. But since this article is about the best Korean hyaluronic acid serums, let’s talk about that.
Simply pat dry your skin after cleansing. If you use a toner, use that, if not, you can go ahead and gently squeeze a few drops of your hyaluronic acid serum directly on your face and with the palm of your hands, apply it in an upward direction.
Don’t forget to lock this in with a moisturizer.

What foods are rich in hyaluronic acid?

All that being said, know that too much of anything can be harmful. Knowing that hyaluronic acid is already present in our bodies, it is safe to say that there are ways to increase and boost the production of hyaluronic acid naturally as well. 
There are some hyaluronic acid foods that you can eat that will stabilize the production over a consistent period of time. Some of the greatest examples are water-rich vegetables like cucumber and celery. But other than that, including root vegetables, bone broth and sweet potatoes in your diet is also helpful.

Can I use hyaluronic acid serum every day?

Yes, you can use a hyaluronic acid serum every day, provided you’re applying it to clean skin that is freshly washed and damp. In fact, you can apply it twice a day by incorporating it into your AM and PM routine. Remember to wait a few minutes and lock the effects of your skin by following it up with a moisturizing cream and face oil.

Can the hyaluronic “acid” serum cause any side effects?

It is unlikely that this ingredient will cause any sort of eruption or negative reaction to your skin considering it is already found in your body. The external use of hyaluronic acid is simply done in order to replenish the skin with the amount required to resume skin elasticity.

What percentage of hyaluronic acid is best in a serum?

It is safe to assume that most of you think that the higher the concentration, the more effective it is. But that is not always true. In fact, dermatologists actually suggest that you go for formulations that have 1% hyaluronic acid. Anything higher than 2% can actually cause some skin irritation and inflammation.

What should you not use hyaluronic acid with?

Hyaluronic acid fits the label of a universal ingredient well. It suits all skin types and some hydration for the skin cannot hurt anyone. However, using it with glycolic acid might just make using hyaluronic acid serums moot. The low pH levels of glycolic acid may cancel out any effect that hyaluronic acid may have on you.
As for what it works best with, I’d say Retinol. In fact, if you’re using retinol, I’d urge you to use hyaluronic acid with it. Retinol, as an ingredient, can have an intensely drying effect on the skin, apart from working its magic. Pairing it with hyaluronic acid can help minimize the irritation by keeping the skin hydrated.
While the retinol helps proliferate cell generation and helps in boosting collagen, the hyaluronic acid will help draw water from under the skin to help regenerate the used hydration and make it ultimately plump and fresh!

Does hyaluronic acid serum make your face peel?

This sort of result is conditional and not very common. It is possible that if you have skin that is extremely dry, hyaluronic acid will counteract and pull moisture from within your skin and make it even drier. It can leave your skin feeling taut, tight and the complexion dull.
Another factor that might play a role in this is areas with low humidity levels —  the lack of moisture in the environment plus extremely dry skin cannot be treated with hyaluronic acid.
And there it is — all about Korean hyaluronic acid serum you need to know! Hopefully this post helped you pick the right Korean hyaluronic acid serum for your skin! 


In conclusion, choosing the best Korean hyaluronic acid serum is a crucial step in achieving healthier, more youthful-looking skin. With their dedication to innovation and quality, Korean skincare brands have emerged as leaders in the industry, consistently delivering products that cater to a wide range of skin types and concerns.

Throughout this exploration of the best Korean hyaluronic acid serums, we’ve seen that these serums offer numerous benefits. From intense hydration and plumping effects to their ability to enhance the skin’s natural radiance and elasticity, they have become an indispensable part of many skincare routines.

Remember, the key to finding the perfect hyaluronic acid serum for your skin lies in understanding your unique needs and preferences. Factors such as your skin type, budget, and specific concerns should guide your decision-making process. Whether you opt for a cult-favorite like the COSRX Hyaluronic Acid Hydra Power Essence or a newcomer on the market, the Korean skincare industry continues to offer a diverse array of options to suit your skincare journey.

Ultimately, investing in a high-quality hyaluronic acid serum is an investment in the health and beauty of your skin. It’s not just about chasing trends or jumping on the K-beauty bandwagon; it’s about nourishing your skin with the best ingredients that science and nature have to offer.

So, take the time to explore and find the Korean hyaluronic acid serum that will help you achieve your skin goals, and embrace the path to healthier, more radiant skin. Your skin will thank you for it in the long run.
