The Hyaluronic Acid Serum That Gives You Instant Younger-Looking Skin

Last Updated on December 2, 2025 by Giorgia Guazzarotti

If there’s one thing I’ve learned from Korean skincare is that moisture is the foundation of younger-looking skin. You can throw all the anti-aging ingredients your heart desires at your wrinkles, but if your skin isn’t hydrated enough, those pesky wrinkles are gonna look 10x worse. How do you make sure your skin is hydrated enough, then? Hyaluronic Acid. It’s one of the most popular ingredients in Korean skincare for a reason: it’s the holy grail of hydration. Most hyaluronic acid serums out there do a wonderful job at hydrating skin. But they stop at that. Mizon Hyaluronic Acid 100 goes a step further: it targets dryness and wrinkles so you can treat both at the same time. Here’s how:

Key Ingredients In Mizon Hyaluronic Acid 100

HYALURONIC ACID TO HYDRATE SKIN

Korean women are obsessed with Hyaluronic Acid. They know hydration is the foundation of healthy, younger-looking skin – and nothing hydrates skin better than Hyaluronic Acid. It secret? It can hold up to 1000 times its weight in water! Here’s how it works: Hyaluronic Acid attracts moisture from the air all around you as well as from the deeper layers of your skin. It’s not as drying as you think. Your skin is more than 60% water. Hyaluronic Acid just redistributes it around.

Your skin then uses that extra moisture to look its best: it softens to the touch, plumps up so fine lines and wrinkles look smaller, and glows as if lit from within. Mizon Hyaluronic Acid 100 contains Sodium Hyaluronate, a smaller form of Hyaluronic Acid better able to penetrate skin. It’s the second ingredient, so there’s A TON of it here. I dare you to find something more hydrating than this!

CERAMIDE 3 TO STRENGTHEN YOUR SKIN’S PROTECTIVE BARRIER

It’s not enough to add moisture to your skin. You also needs to keep it there. Hyaluronic Acid binds water into the skin to an extent, but if your skin is dry, you’ll need more help than that. Enter ceramides. They’re oily waxes (“cera” means wax in Latin) that make up the glue that holds skin cells together (together with fatty acids, cholesterol etc). Ceramides waterproof skin. The barrier they create has two jobs:

• It keeps moisture in, preventing skin from becoming dry and cracked
• It keeps bacteria, germs, pollutants, and all sort of nasty stuff out of the body, preventing infections and irritations

Mizon Hyaluronic Acid 100 has only one Ceramide, i.e. ceramide-3. But it’s paired with cholesterol, another component of your skin’s protective barrier that’s known to boost the effects of ceramides.

Copper Tripeptide-1 To Firm Skin

Peptides have taken the skincare world by storm. But I’m not their biggest fan. Truth is, we still don’t have solid evidence they do much of anything. The exception? Copper peptides. Mizon Hyaluronic Acid 100 contains Copper Tripeptide-1 (a.k.a. GHK-Cu), a peptide that helps:

• Heal wounds: It breaks down degraded collagen in scar tissue and stimulates the production of healthy new collagen to heal skin faster.
• Boosts collagen: It stimulates the production of collagen, the protein that keeps skin firm, as well as that of elastin, the protein that keeps it elastic.
• Anti-inflammatory: It has soothing properties that help reduce inflammation.

In other words, it helps skin heal faster, improve firmness and elasticity and reduce fine lines and wrinkles. The catch? Don’t expect results overnight. You need to use it constantly for years to see a difference. FYI, most copper peptides serums cost an arm and a leg. Mizon Hyaluronic Acid 100 is an affordable way to incorporate them into your skincare routine and see for yourself what the fuss is about.

The Rest Of The Formula & Ingredients

• Water: Water is your solvent base – everything else dissolves in it and it helps transport the active ingredients into your skin so they can actually do their job instead of just hanging out on the surface.
• Copper Tripeptide-1: This is one of those rare peptides that actually has solid research behind it showing it can stimulate collagen synthesis and help with wound healing – it literally signals your fibroblasts to get to work making more collagen and elastin, which is why it’s become such a big deal in anti-aging skincare.
• Butylene Glycol: It’s a humectant so it pulls moisture into your skin, but it also acts as a penetration enhancer which means it helps all those expensive active ingredients actually get where they need to go instead of just sitting on top doing nothing, plus it gives products a nice slip without being sticky.
• Sclerotium Gum: This comes from mushrooms and it’s basically just a natural thickener that gives the product that gel texture so it’s not all watery and impossible to spread – it keeps everything at the right consistency.
• 1,2-Octanediol: It helps preserve the formula by preventing bacterial and fungal growth, and it’s also a humectant with some antimicrobial properties of its own, so you’re getting preservation and a little extra moisture at the same time.
• Ethylhexylglycerin: Another preservative booster that works alongside other preservatives to keep nasty stuff from growing in your product, and it also happens to condition your skin and improve the texture so everything feels smoother going on.
• Tropolone: This preserves the formula while also providing antioxidant benefits, so it’s protecting the product itself from degrading while also helping protect your skin from free radical damage once you apply it.
• Hydrogenated Polydecene: It’s an occlusive that creates a barrier on your skin to prevent water from evaporating out, but it’s way lighter and less greasy than something like petrolatum so you get the hydration-locking benefits without feeling like you’ve slathered Vaseline all over your face.
• Caprylic/Capric Glycerides: These are medium-chain triglycerides from coconut oil that work as emollients to soften your skin and help the product spread easily, and they’re lightweight enough that they won’t leave you looking shiny or feeling greasy.
• Hydrogenated Lecithin: Sure it’s an emulsifier that keeps the oil and water phases mixed together, but what’s cool is that it’s also structurally similar to the lipids in your skin barrier so it actually helps repair barrier damage while it’s doing its emulsifier job.
• Stearic Acid: This fatty acid thickens the formula and gives it a creamier texture, and it also acts as an emollient to soften your skin, so it’s improving both the feel of the product and what it does for your skin.
• C12-20 Alkyl Glucoside: It’s a really mild emulsifier made from coconut and glucose that keeps everything blended together, and because it’s so gentle it won’t irritate even really sensitive skin which is why you see it in products for people with reactive skin.
• C14-22 Alcohols: These are fatty alcohols which are totally different from the drying alcohols that strip your moisture barrier – these actually make the texture richer and help stabilize the emulsion so the oil and water don’t separate over time.
• Glyceryl Stearate: It emulsifies the formula to keep everything mixed while also moisturizing your skin and giving you that smooth, almost velvety feel when you’re applying it.
• PEG-100 Stearate: Another emulsifier that keeps the formula stable and improves the texture so it spreads nicely and doesn’t feel weird or patchy on your skin.
• Cholesteryl Hydroxystearate: This is a lipid that your skin already makes naturally, so when you apply it topically it helps reinforce your moisture barrier and prevents transepidermal water loss, which is just the fancy term for water evaporating out of your skin.
• Cholesterol: Your skin barrier needs a specific ratio of ceramides, cholesterol, and fatty acids to function properly, so adding cholesterol back in helps maintain that balance and keeps your barrier doing its job of keeping moisture in and irritants out.
• Triethanolamine: It adjusts the pH of the formula to keep it in the optimal range for your skin, because if the pH is too high or too low it can cause irritation or make other ingredients less effective.
• Carbomer: It’s a synthetic polymer that thickens the product into that gel consistency, and it also helps suspend other ingredients evenly throughout the formula so they don’t just sink to the bottom and leave you with an inconsistent product.
• Betula Platyphylla Japonica Juice: This is sap from Japanese white birch trees and it’s loaded with minerals, enzymes, proteins, and antioxidants that hydrate your skin while calming inflammation, so you’re getting both moisture and soothing benefits.
• Portulaca Oleracea Extract: Purslane doesn’t get nearly enough attention but it’s packed with omega-3 fatty acids, vitamins, and antioxidants that soothe irritation and protect your skin from oxidative stress and environmental damage.
• Scutellaria Baicalensis Root Extract: Chinese skullcap has powerful anti-inflammatory and antioxidant properties thanks to compounds like baicalin, so it calms redness and protects your skin from the kind of damage that leads to premature aging.
• Astragalus Membranaceus Extract: This adaptogenic herb has antioxidant and immune-supporting properties that help your skin deal with stress better, and some research suggests it might even help with wound healing.
• Arnica Montana Flower Extract: Arnica’s been used for centuries to reduce inflammation and bruising, and in skincare it helps calm irritated skin and reduce redness, though you want to make sure it’s properly diluted because it can be sensitizing in high concentrations.
• Artemisia Absinthium Extract: Wormwood has antimicrobial and anti-inflammatory properties that help keep your skin calm and clear, and despite the somewhat intimidating name it’s actually pretty gentle when it’s formulated correctly.
• Achillea Millefolium Extract: Yarrow brings anti-inflammatory and astringent benefits that soothe irritation and can help balance oil production if you have oilier skin, plus it’s got antioxidants for some extra protective benefits.
• Gentiana Lutea Root Extract: Gentian root provides antioxidant protection and has some potential for brightening your skin tone, plus it’s been shown to have anti-inflammatory effects that can help calm sensitized or reactive skin.
• Rubus Idaeus (Raspberry) Fruit Extract: Raspberry extract is rich in vitamins C and E plus ellagic acid, so you’re getting antioxidant protection against free radical damage and some gentle anti-aging benefits without the irritation you’d get from harsher actives.
• Beta-Glucan: Usually derived from oats or mushrooms, and it’s incredibly soothing because it activates immune cells in your skin that help with healing, plus it’s a humectant that holds onto moisture and reduces inflammation really effectively.
• Adenosine: This occurs naturally in your body and there’s clinical evidence showing it reduces wrinkles and improves elasticity by basically giving your skin cells an energy boost so they function better, plus it’s anti-inflammatory so it’s way gentler than most anti-aging ingredients.
• Disodium EDTA: It’s a chelating agent that binds to metal ions in the formula that could otherwise destabilize the product or cause oxidation, so it keeps everything stable and extends the shelf life so your active ingredients stay effective for longer.

Texture

This serum has a lightweight, watery texture that sinks into your skin fast. It feels slightly sticky for maybe a second or two while it’s settling in, but then that tackiness disappears completely. It’s not like those glycerin-heavy serums where you feel sticky for hours and regret your life choices. Once it sets, it creates this perfect smooth base for whatever you want to layer on top – moisturizers, oils, whatever.

Fragrance

There’s no fragrance in this, which is exactly what you want in a serum full of active ingredients. Your skin gets the good stuff without any unnecessary irritants.

How To Use It

I apply this at night after my retinol or salicylic acid serum but before moisturizer. The hyaluronic acid and peptides play nice with actives, so you don’t have to worry about layering issues. You can also use it in the morning if your skin’s feeling dry or dehydrated. Honestly, when winter hits I’ll probably use it twice a day because my skin turns into the Sahara Desert when it gets cold.

Packaging

It comes in this rounded aqua-colored bottle that’s actually really pretty sitting on your bathroom sink. The dropper applicator is one of those good ones that dispenses just the right amount of product, so you’re not wasting half the bottle or struggling to get enough out.

Performance & Personal Opinion

This is hands down one of the most hydrating serums I’ve tried. The hyaluronic acid pumps moisture into your skin immediately – like you can literally see your skin plump up within seconds of applying it. Your face looks softer, smoother, younger, healthier, all that good stuff. There’s even this subtle glow that happens.

Now, the copper peptides are in here for anti-aging benefits, but those take time to work. You’re not going to wake up with firmer skin overnight because peptides need consistent use over weeks to show results. But the immediate hydration? That’s instant gratification right there. What I really appreciate is that it delivers all this moisture without feeling greasy or heavy or clogging your pores. It just does its job and gets out of the way so you can continue with the rest of your routine.

What I Like About Mizon Hyaluronic Acid 100

• The hydration is instant and visible – your skin literally plumps up right in front of your eyes
• Lightweight texture that absorbs fast without any lingering stickiness
• Doesn’t feel greasy or clog pores despite being super hydrating
• Works under other products without pilling or feeling heavy
• The dropper applicator actually works well and dispenses the right amount
• No fragrance to irritate your skin
• Suitable for all skin types, even oily or acne-prone

What I DON’T Like About Mizon Hyaluronic Acid 100

• The copper peptides take their sweet time to show firming results, so don’t expect overnight miracles
• That brief moment of stickiness before it sets might annoy some people, even though it’s short-lived
• If you’re looking for dramatic anti-aging results fast, this isn’t going to deliver that immediately

Who Should Use This?

Honestly? Pretty much everyone. Dry skin? This will save your life. Oily or breaking out? You get hydration without the grease or clogged pores. Sensitive skin? No fragrance, no bullshit ingredients that’ll piss your skin off. Normal skin? The hyaluronic acid keeps everything plump and happy while the copper peptides work on preventing aging down the line.

It’s especially great if you want real hydration but hate feeling like you’ve got a thick, suffocating layer of product on your face. Like you want moisture, not a face mask you can’t take off.

Does Mizon Hyaluronic Acid 100 Live Up To Its Claims?

Price & Availability

Available at: $18.10 at Cult Beauty, Stylevana, and Yes Style

This is really affordable considering you’re getting both hyaluronic acid and copper peptides without paying luxury skincare prices. You can find it on K-beauty sites, Amazon, wherever you usually buy Korean skincare online.

The Verdict: Should You Buy It?

Yes. Get it. If your skin needs hydration or you want to add peptides to your routine without spending a fortune, this is it. The instant plumping from the hyaluronic acid alone is worth it, and the copper peptides are doing their thing for long-term benefits. It works for everyone, doesn’t clog your pores, layers well with everything else in your routine, and delivers on the hydration. Plus it’s affordable.

Don’t expect it to erase your wrinkles in a week or give you completely different skin overnight because that’s not realistic. But if you want a hydrating serum that makes your skin look and feel amazing immediately while working on improvements over time? Buy it. You’ll be happy you did.
