Why numbuzin is so popular
If you've seen bottles with big numbers on them in K-beauty videos, that's numbuzin. Instead of giving every product a long name, the Korean brand sorts its line into numbered families, each with its own focus. That makes it easy to build a routine: pick the number that matches what you want, then add from there.
The No.9 family is the current favorite. It's built around NAD+ and a long list of peptides, aimed at skin that looks firmer and bouncier. The No.5+ family, centered on glutathione and vitamins, is the go-to for anyone chasing a brighter, more even-looking complexion. The No.9 essence and No.5+ serum are our two best-selling numbuzin products.
Where to buy numbuzin in the USA
numbuzin isn't widely stocked in US department stores yet, so shoppers usually choose from:
- Marketplace listings. Easy to find, but listings are often from third-party resellers. Read recent reviews and confirm the seller before you buy.
- Korean beauty stores. Shops in cities with large Korean communities may carry the most popular numbers.
- Overseas K-beauty sites. Wide selection, but international shipping can be slow and import fees may apply.
Kiyoko Beauty stocks a large numbuzin collection that's sourced directly from Korea and shipped from inside the US, duty-free, with free shipping on orders over $55.
How to spot authentic numbuzin
- Made in Korea. Genuine numbuzin is made in South Korea, and the packaging should say so clearly.
- Crisp printing. The number, product name and ingredient list should be sharp and easy to read. Fuzzy text or crooked labels are warning signs.
- Prices that make sense. Big discounts from unknown sellers can mean expired, gray-market or counterfeit stock.
- A store with a track record. Buy from a retailer that sources directly and has a large base of verified reviews.

Each pad has two sides: a jelly side infused with essence and a cotton gauze side. Glutathione, niacinamide and tranexamic acid help skin look brighter and more even, while PHA and LHA on the gauze side gently lift away dead skin cells. Tip from the brand: cut a pad in half and rest the jelly side under your eyes for 5 to 10 minutes.
numbuzin No.9 NAD Bio Lifting-Sil Essence (50ml)
Our top-selling numbuzin product. It's packed with NAD+, 50 types of peptides and antioxidants like vitamin E, ubiquinone and glutathione, in a unique elastic texture that absorbs easily. Use it after toner and tap it in, or dab a little under the eyes where fine lines show.
numbuzin No.5+ Glutathione Vitamin Concentrated Serum (30ml)
A vitamin serum with glutathione, niacinamide, alpha-arbutin and tranexamic acid, designed for skin that looks dull or uneven. It's fragrance-free and alcohol-free. After cleansing and toning, smooth 3 to 5 drops over your whole face.
numbuzin No.9 NAD+ Retinol Volumetox Eye Cream (10ml)
A pearlescent eye cream that combines retinol, NAD+, peptides and ceramide to help the under-eye area look smoother, brighter and less puffy. numbuzin recommends it for nightly use. Pat a small amount around the eyes and crow's feet after toner.
numbuzin No.9 NAD+ Bio Super Defense Glow Sunscreen SPF 50 (50ml)
An SPF 50 sunscreen for UVA and UVB rays with a lightweight, creamy texture that absorbs quickly without patchiness or stickiness. Wear it alone for a glassy glow, or under makeup.
numbuzin No.9 NAD Bio Lifting-sil Full Face Mask
This mask comes in two parts, a top sheet and a bottom sheet with ear loops, plus a separate band you can hook under your chin. NAD+, peptides and hydrolyzed collagen are in the essence. Keep it on for 20 minutes or more for a radiant, lifted-feeling finish.
How to layer numbuzin No.5+ and No.9
A lot of US shoppers end up with products from both No.5+ and No.9, since they're the two most popular families. They layer well if you go thinnest to thickest:
- No.5+ Pad first. Use the jelly side as a short mask on the areas you want brighter-looking, then wipe with the gauze side.
- No.5+ Serum next. A few drops over the whole face.
- No.9 Essence after that. Tap its elastic texture in over the serum.
- No.9 Eye Cream at night. Finish around the eyes.
In the morning, skip the pad and eye cream and end with the No.9 Sunscreen.

AM: cleanser, No.5+ Serum, No.9 Essence, moisturizer, No.9 Sunscreen SPF 50.
