The toner step is often where Korean skincare routines do their heaviest lifting β and the numbuzin No.9 NAD+ Salmon PDRN Glow Boosting Toner might be the most ambitious toner formula currently available on Amazon.

I have been layering this toner into my routine daily for seven weeks. Here is everything you need to know.

About numbuzin
numbuzin (pronounced “num-boo-zin”) is a Korean skincare brand whose name derives from the Korean word for “skin” (νΌλΆ, “pibu”) β a nod to their laser focus on skin-first formulation. The brand has built a devoted following through their numbered product line, each number representing a distinct skin concern with a targeted formula. No.3 (brightening), No.5 (texture), and No.9 (regeneration + glow) are among the most discussed in K-beauty communities globally.
Why NAD+ and PDRN Together?
This pairing is scientifically intelligent, not just a trend-stacking exercise:
- PDRN (Polydeoxyribonucleotide): Promotes cellular repair, activates collagen synthesis, and reduces inflammation. Works at the level of DNA repair and tissue regeneration.
- NAD+ (Nicotinamide Adenine Dinucleotide): Provides cellular energy currency (ATP) and activates sirtuin longevity proteins involved in DNA repair and stress resistance.
Together, they address skin aging from two angles: PDRN stimulates the structural repair machinery; NAD+ powers the cellular energy needed to run it. Think of PDRN as the blueprint and NAD+ as the electricity that runs the construction site.
Full Ingredients Breakdown
Salmon PDRN
The same salmon-DNA-derived ingredient used in Korean dermatology injectables. In this toner, it delivers surface-level regenerative support, targeting fine lines, uneven texture, and post-acne marks.
NAD+ (Nicotinamide Adenine Dinucleotide)
Stabilized NAD+ compound that supports cellular energy metabolism and activates repair enzymes. Enhances the skin’s natural resilience to UV, pollution, and oxidative stress.
Niacinamide (10%)
A high-dose niacinamide inclusion that brightens hyperpigmentation, tightens pores, and complements NAD+ through the shared B3 metabolic pathway. At 10%, this is a meaningful clinical dose.
Heartleaf Extract
Anti-inflammatory and pore-refining; soothes the skin while the actives do their work. A familiar calming companion across premium K-beauty serums.
Galactomyces Ferment Filtrate
A yeast fermentation byproduct rich in vitamins, minerals, and amino acids. Improves skin texture and luminosity β the “glass skin” ingredient beloved by Japanese and Korean beauty brands alike.
Hyaluronic Acid (Triple Molecular Weight)
Surface, mid-layer, and deep plumping for comprehensive hydration. Essential in a toner that is layered before serums and moisturizers.
Texture, Scent and Feel on Skin
The toner is a clear, slightly viscous watery liquid β thicker than water but not at all gel-like. It pours easily, spreads beautifully with cotton pad or hands, and absorbs within seconds without tackiness.
There is a very faint, clean cosmetic scent that dissipates almost immediately. Fragrance-sensitive users should patch-test, but most find it non-irritating. The formula is alcohol-free.
How to Use It: Layering Techniques for Glass Skin
The toner step is the foundation of K-beauty hydration layering. Here are two proven methods:
Method 1: Cotton Pad (Exfoliating Sweep)
- Soak a cotton pad until fully saturated
- Swipe gently across face in upward strokes
- Gently press the saturated pad against the skin for 10β15 seconds (essence-pad technique)
- Proceed to serum
Method 2: Hands (7-Skin Method)
- Pour a 50-cent coin amount into palms
- Press and pat into skin β do not rub
- Repeat 3β7 times, allowing each layer to absorb
- Skin will feel intensely plump and dewy after multiple layers
For a complete glass-skin routine, pair with:
- REJURAN Turnover Ampoule (serum step)
- A ceramide moisturizer to seal
- Korean mineral SPF
7-Week Results Log
- Week 1: Skin feels immediately more hydrated and plump post-application. Morning dullness noticeably reduced.
- Week 2β3: Pores appear tighter. Uneven tone begins to even out β particularly sun-related discoloration.
- Week 4β5: Texture smoothing becomes visible. Skin has a consistent dewy, lit-from-within quality even before moisturizer.
- Week 6β7: Fine lines softer, especially around eyes and forehead. Complexion significantly more radiant and even. Glass-skin effect achievable most mornings with the right layering.

Frequently Asked Questions
Can I use the numbuzin No.9 Toner twice a day?
Yes β morning and evening use is recommended and safe. Using it twice daily significantly accelerates the niacinamide brightening and PDRN regenerative benefits.
Will 10% niacinamide cause flushing or irritation?
Some users experience mild initial tingling or a temporary flush, which usually resolves within a week as skin adjusts. Start with once-daily use if you have sensitive skin, then build to twice daily.
Can I layer this with other niacinamide products?
Yes, though if you are already using multiple high-dose niacinamide products, total daily dose can build up. Most dermatologists consider up to 15β20% total daily niacinamide safe; track your other products accordingly.
Does it work for hyperpigmentation?
Yes β the 10% niacinamide at the toner step is one of the most effective delivery points for brightening, as it is applied to clean, bare skin before any other products. Combined with PDRN’s repair action, most users see significant improvement in PIH over 6β8 weeks.
Is it suitable for dry skin?
Yes. The triple hyaluronic acid complex makes it very hydrating. Dry skin types should follow with a rich moisturizer to seal the hydration in.
How does this compare to the numbuzin No.3 toner?
No.3 focuses on brightening with a niacinamide-led formula. No.9 adds NAD+ and PDRN for cellular regeneration alongside the brightening benefits, making it the more comprehensive anti-aging choice of the two.
