Numbuzin

Numbuzin numbers its products instead of naming them, and once you know what each number targets, the range stops looking like a confusing catalog and starts looking like a set of specific answers — brightening serum, under eye patches, dark spot treatment, and more, each built around a different active ingredient story.

No.9 NAD+: under eye patches and the anti-aging line

NAD+ is the ingredient behind Numbuzin's most talked-about line. The No.9 NAD+ Collagen Under Eye Patches pair with the No.9 NAD+ Retinol Volumetox Eye Cream for a targeted under-eye routine, while the No.9 NAD+ Bio Lifting-Sil Essence and matching Full Face Mask extend the same lifting benefit across the whole face. The No.9 NAD+ PDRN Glow Booster Toner and No.9 NAD+ Peptides Dewy Sun Essence round out the line with hydration and sun protection.

No.9 NMN: the alternative anti-aging active

NMN works on a related anti-aging pathway to NAD+, and Numbuzin offers a parallel line for anyone who prefers it — the No.9 NMN Collagen Under Eye Patches, NMN Retinol Volumetox Eye Cream, and NMN Bio Lifting-Sil Essence mirror the NAD+ range one for one.

No.5: the brightening serum and dark spot line

The No.5+ Glutathione Vitamin Concentrated Brightening Serum is the reference product in this line, paired with the No.5+ Vitamin Niacinamide Pad Serum for daily toning. For stubborn discoloration specifically, the No.5 Glutathione TXA Advanced Dark Spot Ampoule combines glutathione with TXA, and the No.5 Dark Spot Laser Cream and No.5 Good Bye Blemish Serum extend the same brightening focus. No.5 Daily Multi-Vitamin Cream and the No.5 Glutathione Vitamin Tone Up Sun Serum cover moisturizing and sun protection in the same line.

No.1 and No.2: soothing and plumping

The No.1 line focuses on calming: Pure-Full Calming Herb Toner, Pantothenic B5 Active Soothing Serum, and the matching Soothing Cream, plus a Clear Mask. The No.2 line targets plumpness with Rose PDRN Collagen 2X Plumping Serum, using rose and PDRN together for volume and hydration.

No.3: pore care and tone-up sun serum

The No.3 Bifida Bakuchiol Zero Pore Serum pairs with a matching toner, moisturizer, exfoliating pads, and cleansing oil for pore-focused skin. The No.3 No Filter Tone Up Sun Serum, in both Blur and Glow finishes, doubles as sunscreen and a light base.

No.4 and No.6: quick treatments

The No.4 Icy Soothing Sheet Mask handles fast calming, and the No.6 Deep Sleep Mask Serum is an overnight treatment for recovery while you sleep.

Frequently asked questions

Why does Numbuzin use numbers instead of product names?

Each number represents a distinct concern and ingredient focus — No.5 for brightening and dark spots, No.9 for anti-aging with NAD+, No.3 for pores, and so on — making it easier to shop by concern once you know the system.

NAD+ or NMN — which line should I choose?

They target a related anti-aging pathway through slightly different mechanisms. Neither is objectively better; choosing between them usually comes down to which you'd rather try first, or which fits your budget.

Are the under eye patches meant for daily use?

They can be used regularly, but many people reserve them for specific moments — the morning after poor sleep or before an event — rather than as a daily step.
