I kept seeing the SIORÉ NMN Intensive Serum pop up on my feed with those “filler in a bottle” claims, so I finally caved and tried it.
If you’re staring at tired under-eyes, dullness, or early fine lines and wondering if this Korean pharmacy anti-aging serum actually earns the hype, keep reading. I broke down the ingredients, the feel, the flaws, and who should skip it.
In a Nutshell
- 99% purity NMN at 10,000ppm is the hero ingredient, aimed at firming and boosting a natural glow through NAD-related skin support.
- The formula pairs NMN with Salmon DNA PDRN, Glutathione, Alpha-Lipoic Acid, Carnosine, and Pycnogenol for antioxidant and barrier benefits.
- Texture is a lightweight gel with a non-sticky, glassy finish and no notable scent, which makes it easy to layer.
- Rated “Excellent” by Germany Dermatest with a stated 0.00 irritation index, so it targets all skin types, including sensitive.
- Price sits around $38 USD for 1.69 fl oz, which is mid-range for the ingredient list you get.
- Best for people chasing plump, hydrated, brighter skin; less ideal if you want fast, dramatic wrinkle correction like a retinoid.
What Is the Siore NMN Intensive Serum
The SIORÉ NMN Intensive Serum is marketed as a plumping, firming, and glow serum built around NMN, a molecule tied to NAD production in cells. The brand frames it as a next-generation anti-aging ingredient rather than another basic hydrator.

It’s sold by SIORÉ and manufactured by Beauty & Balance Korea. The pitch centers on cell-level support: firmer, bouncier skin and a healthier glow over time. Realistically, this is a daily maintenance serum, not an overnight fix. I read it as a “keep skin looking fresh and hydrated” product with some genuine antioxidant backup.
Full Ingredient Breakdown
The active lineup is where this serum gets interesting. NMN (Nicotinamide Mononucleotide) leads at 10,000ppm, working on NAD-related pathways some studies link to collagen support. It’s the reason people call this a filler-style serum.
Then you get Salmon DNA PDRN, a polynucleotide known for skin repair and barrier support, plus Glutathione and Alpha-Lipoic Acid for antioxidant defense. Carnosine adds anti-glycation benefits, and Pycnogenol (pine bark) brings more antioxidant power.
It’s a genuinely thoughtful stack for anti-aging skin types. My honest note: the ingredient story is stronger than most serums at this price, though exact percentages beyond NMN aren’t published.
How the Siore NMN Serum Performs
In use, this feels less like a “wow” serum and more like a slow-burn glow builder. After a couple of weeks, my skin looked plumper and more hydrated, especially around the under-eye area where I get crepey texture.

I didn’t see dramatic wrinkle erasing, and I want to be honest about that. The firming claim reads more like “smoother and bouncier” than tightened. Where it shined for me was dullness, giving that soft, healthy-lit look people describe as glass skin. If your main goal is deep wrinkle correction, temper expectations; this is subtle, cumulative work, not a rapid transformation.

Siore NMN Deep Glow Rich Cream
Unboxing and First Impressions
The unboxing feels clean and pharmacy-like, which fits the brand story. No excessive packaging, just a simple box and the bottle. It reads understated and clinical rather than luxury, and I appreciated that.
The serum arrived well-sealed with clear labeling of the key actives on the outer box. First impression out of the box: it looks like a no-nonsense treatment serum, not a trend product.
For a $38 serum, the presentation matches the price without pretending to be premium. Nothing flashy, nothing cheap-feeling. It’s the kind of packaging that quietly signals “this is about the formula,” which I find refreshing after so many over-designed drops.
Texture Scent and Absorption
Texture is the highlight for me. It’s a lightweight gel that spreads thin and sinks in fast, leaving a non-sticky, slightly dewy finish. No greasy residue, no tacky film that fights your next layer.
Scent-wise, it’s listed as unscented, and that’s accurate. I picked up almost nothing, which is great for sensitive or fragrance-avoidant skin. Absorption is quick enough that I could follow with moisturizer or SPF within a minute.
It layers beautifully under makeup too, giving that plump, glassy glow without pilling in my experience. If you dislike heavy, occlusive serums, the feather-light feel here is a genuine selling point.
Packaging and Functionality
The bottle is functional and travel-friendly, sized at 1.69 fl oz. Dispensing is clean, and I didn’t deal with leaks or messy overflow, which matters for a serum you’ll reach for daily.
My one wish: more transparency on light and air protection, since NMN and antioxidants like Glutathione can degrade with exposure. Opaque or airless packaging would reassure me the actives stay stable through the whole bottle. It’s a small gripe, but for an antioxidant-heavy formula, packaging integrity affects how well those ingredients actually perform by the time you hit the bottom. Store it somewhere cool and dark to be safe.
Honest Claims Versus Reality
SIORÉ leans on “filler cocktail” and dramatic firming language, so let me translate. “Firming” reads as smoother, bouncier skin, not a tightening result you’d get from in-office treatments. Manage that gap upfront.
The “0.00 irritation index” and Dermatest “Excellent” rating are reassuring, and my skin agreed; no stinging or breakouts. The glow and plumping claims held up best in real life. What I’d push back on is any implication of fast, visible anti-wrinkle change.
That’s the weakest link. Treat this as a hydration-and-radiance serum with long-term antioxidant perks, and you’ll likely be happy with what you actually get.
Who Should Skip This Serum
Let me be direct about the downsides. If you want fast, measurable wrinkle reduction, a retinoid will outwork this serum, and you may find the results here too subtle.
If you’re on a tight budget, $38 for a smaller bottle is a real consideration, since gentler hydrating serums cost less. People sensitive to marine-derived ingredients should note the Salmon DNA PDRN and patch test first.
And anyone allergic to fish or pine bark (Pycnogenol) should approach carefully. This serum is genuinely gentle for most, but “suitable for all skin types” doesn’t erase individual allergies. When in doubt, do a small patch test on your inner arm before full-face use.
My Final Verdict
After weeks of testing, I’d call the SIORÉ NMN Intensive Serum a quiet overachiever for glow and hydration. It won’t replace a retinoid, but that’s not really its job. Its strength is plump, healthy, glass-skin radiance.
The ingredient stack is genuinely strong for the price, the texture is a dream, and it played nice with my sensitive skin. If your concerns are dullness, dehydration, tired under-eyes, and early bounce loss, this is an easy yes. If you’re chasing dramatic wrinkle correction, look elsewhere or pair it with an active. For me, it earned a permanent spot in my morning routine, and I’ll likely repurchase.
Frequently Asked Questions
Is the Siore NMN Intensive Serum good for sensitive skin?
Yes, in my experience. It carries a Dermatest “Excellent” rating and a stated 0.00 irritation index, is unscented, and felt gentle on my reactive skin. That said, patch test first if you react to marine-derived ingredients like Salmon DNA PDRN or to pine bark extract.
How do you use the Siore NMN serum?
Apply a few drops to freshly cleansed skin, pat gently, and let it absorb for about a minute. Follow with your moisturizer, and always finish with SPF in the morning. I used it twice daily and it layered well under both cream and sunscreen without pilling.
Can I use it with retinol or vitamin C?
Generally yes. NMN, PDRN, and antioxidants are low-conflict ingredients that layer nicely with most actives. If you’re combining it with a strong retinoid, introduce slowly and watch for irritation. I’d apply this hydrating serum first, then buffer stronger actives on separate nights if your skin is sensitive.
How long until I see results?
Give it four to eight weeks of consistent use. I noticed hydration and glow within two weeks, but the plumping and smoothing benefits built gradually. This is a maintenance-style serum, so results are cumulative rather than instant. Consistency matters more than quantity here.
Is it worth the price?
For the ingredient list, I think it’s fair value at around $38. You’re paying for high-purity NMN plus PDRN, Glutathione, and Pycnogenol, which is a strong stack. If budget is tight or you want dramatic wrinkle results, cheaper hydrators or a retinoid may suit you better.
