numbuzin No.3 and No.9 in Australia: The Skin Softening Serum, the NAD+ Longevity Ritual and Which to Buy

Two numbers get most of the attention in the numbuzin range. One is old and loved: the No.3 Skin Softening Serum, the product reviewers compare to essences that cost several times as much. The other is new and ambitious: No.9, the NAD+ line that borrows the language of longevity. Here is how they differ and who each is for.

If you have searched for numbuzin no 3, numbuzin no 9 or numbuzin skin softening serum, this is the comparison. The numbering guide is in our numbuzin numbers guide, and everything is in the numbuzin collection.

No.3: the softening line

The numbuzin No. 3 Skin Softening Serum ($29.95) is the most popular product in the range. Retail coverage describes it as packed with fermented ingredients and aimed at the coveted glass-skin glow. It is an essence-style serum: apply after cleansing and toning, then moisturise. The No. 3 Velvet Beauty Cream ($29.95) and Rice Enzyme Cleansing Foam ($22.00) complete it. For a pore-focused step, the No.3 Blue Bio-Retinol Pore Refining Serum ($32.00) adds a retinol-type ingredient; introduce it slowly and use sunscreen.

No.9: the longevity line

No.9 sits on the biggest trend in skincare. Industry coverage describes skin longevity as 2026's umbrella idea, with PDRN, peptides and NAD+-related compounds in the conversation. The No.9 NAD+ Bio-Lifting Silk Essence ($34.00) and No.9 NAD+ PDRN Glow Boosting Toner ($28.00) are the core steps. The NAD+ Retinol Volumetox Eye Cream ($28.00), Bio-Lifting Full Face Mask ($28.95) and Collagen Under Eye Patches ($24.95) are the extras.

The honest caveat on longevity

A doctor writing on Korean skincare notes that the evidence behind NAD-related compounds and PDRN varies considerably, and that they are best seen as supportive additions rather than replacements for sunscreen and established ingredients. That is a fair way to buy No.9: for the feel and the routine, not for a promise.

The Ritual

The numbuzin No.9 The NAD+ Longevity Ritual (from $142.95) bundles the line. Check the product page for what is in each size.
