You wake up, splash water on your face, and look in the mirror. Your skin looks tired. It’s not breakouts — it’s just that flatness. That dull, tight, kind of lifeless look that no amount of moisturizer seems to fix by morning. You’ve tried layering creams, using sheet masks, drinking more water. And it helps a little, but it’s never quite enough.
This is what most people with dehydrated skin actually deal with. Not dryness in the flaky sense. Just skin that doesn’t hold moisture well, doesn’t bounce back, and never looks that naturally lit-up way you want it to.
The Anua PDRN Hyaluronic Acid Capsule 100 Serum is one of those K-beauty serums that’s been quietly getting attention — and when you look at what’s actually inside it, it makes sense why.

What’s Actually in This Anua PDRN Hyaluronic Acid Serum?
Let’s talk about what makes this serum different from the hundreds of “hydrating serums” out there. It’s the combination — not just one hyaluronic acid, but multiple forms of it.
The Triple Hyaluronic Acid Approach
This formula uses several different forms of hyaluronic acid — including Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Potassium Hyaluronate, and Sodium Acetylated Hyaluronate. Each form works at a slightly different skin depth. The result? Hydration that doesn’t just sit on top — it actually goes in.
The total hyaluronic acid concentration is 3%, which is on the higher end for a daily-use serum.
PDRN — What Is Salmon DNA Doing in Your Serum?
PDRN stands for Polydeoxyribonucleotide. It’s derived from Salmon DNA (listed as Sodium DNA in the ingredients). In skincare, PDRN is used to support skin’s natural repair process. It’s common in clinical and Korean dermatology routines for its ability to support skin barrier health and a fresher-looking complexion.
That naturally emerald-green color you see in the serum? That comes directly from the formula’s ingredients — no artificial dye added.
Other Ingredients Worth Noting
Niacinamide is in the mix — great for evening out skin tone and reducing the look of pores. Glutathione adds a brightening effect. Hydrolyzed Collagen supports that plump, bouncy feel. And Adenosine helps with the appearance of fine lines.
It’s also fragrance-free, which is always a good sign for people with reactive or oily skin.
💧 This Korean serum has 1,000+ reviews and a 4.6-star rating. See why.

How to Use the Anua PDRN Hyaluronic Acid Serum (Step by Step)
The capsule format is a little different from a standard pump bottle. Here’s how it actually works in a real routine:
Daily Morning Routine
After cleansing and applying toner, twist open the cap and dispense a small amount — the serum is lightweight, so a little goes a long way. Press it gently into the skin rather than rubbing. Let it absorb before applying moisturizer or SPF.
Night Routine (Sleeping Mask Alternative)
Layer the serum 2 to 3 times on clean skin, building up thin layers. You don’t need a separate sleeping mask if you do this — by morning, your skin should feel noticeably softer and more hydrated.
Makeup Mixing Trick
Mix 1–2 drops of this hyaluronic acid serum with your foundation or base. It gives that lit-from-within finish without looking greasy — a good move if your makeup tends to look patchy or dry mid-day.
A Few Honest Things to Know Before Buying
Also, if you’re expecting a dramatic overnight transformation, this probably isn’t the right expectation. It’s a hydration serum — consistent use over days and weeks is what shows results. Most people notice immediate plumpness and dewy-ness right after applying, but the longer-term improvements take a few weeks.
What Kind of Results Can You Realistically Expect?
Right away, most people notice skin that looks more dewy and refreshed. The moisture-plumping effect is real — it’s one of those serums where you see the difference in your skin’s texture within the first few days of consistent use.
After a week or two of daily use — morning or night — the skin generally starts holding hydration better. It doesn’t look as tired or flat by midday. The Niacinamide and Glutathione also help with brightening, so some people notice an evening of skin tone over time.
If it doesn’t seem to work for you after a couple of weeks, it’s worth checking your routine — are you sealing it with moisturizer? Is your cleanser stripping your barrier? Sometimes the serum isn’t the issue, it’s how it’s being used.
Frequently Asked Questions About PDRN Hyaluronic Acid Serums
Final Thoughts — Is This Anua PDRN Hyaluronic Acid Serum Worth Trying?
If your skin regularly feels dehydrated, looks dull by midday, or just won’t hold moisture the way you want it to — this is a serum that addresses that problem from multiple angles. The multi-form hyaluronic acid approach, the PDRN, and the supporting ingredients like Niacinamide and Glutathione make it more thoughtfully formulated than most serums in this category.
It’s also versatile enough to use in three different ways — morning routine, overnight treatment, or makeup base — which makes it genuinely practical for daily use.
It won’t fix everything overnight, and it works best as part of a consistent routine. But for what it does — deep hydration and a naturally plumped, lit-from-within look — it’s honestly one of the better K-beauty serums available right now.
