How it works
No. 9 NAD+ PDRN Glow Boosting Toner is built around Niacinamide, which supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. Alongside it, the formula carries Glycerin, Sodium Dna and Adenosine, each doing a supporting job rather than competing for the same result. As a toner, it is formulated for its own step in a Korean AM/PM routine, so it works with the rest of a layered routine instead of trying to replace it. Sourced for the Korean market, it is the same formula sold in Korea rather than a US-shelf substitute, with its intact Korean-market batch coding carried through.
Key benefits
- Carries Niacinamide, which supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable.
- Carries Glycerin, which is the formula's core humectant, drawing in moisture and helping every other ingredient spread evenly across the skin.
- Carries Sodium Dna, which is a nucleotide-derived ingredient from the PDRN family Korean skincare has built a fast-growing category around.
- Carries Adenosine, which is Korea's monograph anti-wrinkle functional ingredient, included at a set minimum in cosmetics registered for that claim.
- Formulated as a toner, matched to its step in a Korean AM/PM routine rather than asked to do every job at once.
- Is the Korean-market formula from Numbuzin, with intact Korean-market batch coding rather than a US-reformulated substitute.
Key actives
Niacinamidebrightening and barrier support
Supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use.
Glycerincore humectant hydration
Is the formula's core humectant, drawing in moisture and helping every other ingredient spread evenly across the skin. It sits near the top of most Korean formulas for exactly this reason: it is the base hydration layer everything else in the formula builds on.
Sodium DnaPDRN-family conditioning
Is a nucleotide-derived ingredient from the pdrn family korean skincare has built a fast-growing category around. PDRN-family ingredients are one of the newer signature categories in Korean skincare, associated with a plumper, more resilient-feeling surface.
Adenosinesignal-based anti-wrinkle care
Is korea's monograph anti-wrinkle functional ingredient, included at a set minimum in cosmetics registered for that claim. Korean regulation requires a minimum concentration for a product to carry an anti-wrinkle functional claim, so its presence signals a formula built for that purpose.
Ceramide NPbarrier-lipid support
Is one of the lipids naturally found in the skin's own barrier, included here to round out the formula's structure. Ceramide-carrying formulas are a Korean skincare staple for skin that runs dry or reactive, since they mirror the skin's own lipid makeup.
Is this the same formula sold in Korea, or a US version?
This is the authentic Korean-market version of the formula, not a US-shelf substitute. Numbuzin sells a separate reformulation on some US shelves, and this listing is not that version. The Korean-market batch coding and packaging travel with it, which is the detail worth checking against the box on arrival.
Where does this formula come from?
It comes from the Korean-market catalog rather than a US-shelf reformulation, and the packaging carries the same Korean-market batch coding a shopper would find on the box in Korea. That sourcing is checked on this row before the page is written, not assumed from the product name. It is the detail worth checking against the box on arrival.
Can I use this alongside other actives in my routine?
Yes. Niacinamide is the lead active here, and it is formulated to sit alongside the rest of a routine rather than replace it. Introduce any new step on its own for the first week or two before adding it next to another strong active, so it is easy to tell which product is responsible for any change. Once it is settled into the routine, it layers the way any other toner in a Korean routine does.
What does Niacinamide do in this formula?
Niacinamide supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.
What does Glycerin do in this formula?
Glycerin is the formula's core humectant, drawing in moisture and helping every other ingredient spread evenly across the skin. It sits near the top of most Korean formulas for exactly this reason: it is the base hydration layer everything else in the formula builds on. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.

How to use
- Use the No. 9 NAD+ PDRN Glow Boosting Toner straight after cleansing, morning and evening, while the face is still damp.
- Apply numbuzin No.9 Toner morning and night on freshly cleansed skin. Pour an appropriate amount onto a cotton pad or into your hands. Gently sweep the toner across your face and neck, then pat lightly to help it absorb. F ollow with your favorite serum, cream and sunscreen (in the morning) to keep your glow going strong.
- It goes on before serum and moisturizer, and the damp layer it leaves is what the step above it holds on to.
- Twice a day, every day. Do not let it dry down completely before the next layer goes on, or you lose the reason for applying it to damp skin.
Worth knowing
- Patch test on the inner arm first if trying a new brand's formula for the first time.
- Stop use and check the ingredient list against any known sensitivities before continuing.
