numbuzin No.9 NAD Bio Lifting Concentrate Essence

Ingredient analysis and how the ad lines read

Read on 2026-09-07

What is this product?

numbuzin's No.9 NAD Bio Lifting Concentrate Essence (50ml) packs an unusually large peptide roster, more than forty named signal and growth-factor-mimetic peptides, around a trace 50ppm dose of NAD and 50ppm of ATP. The NAD naming is genuine and matches the disclosed ingredient, though an older product-page slug and one retail listing instead say NMN, a different molecule not found in the ingredient list. No brand-run clinical test for this exact serum, and no pH, were found in the archived material, so the lifting claim rests on ingredient breadth rather than a measured result.

What makes it different?

A peptide roster over forty entries deep, spanning signal peptides, copper peptides and several sh-prefixed growth-factor mimetics, is the structural fact that sets this apart from a typical single- or double-peptide serum. NAD, ATP and resveratrol are all disclosed at exact trace concentrations (50ppm, 50ppm and 4ppm), a level of transparency most competitors do not offer even at these small doses. The naming itself is unsettled across channels: this SKU's catalog identity and current retail listings say NAD, but an older brand-page address and one price-comparison listing say NMN, a different compound absent from the disclosed ingredient statement.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

Key ingredient

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

We could not place these in the list above: 펜타에리스리틸테트라에틸헥사노에이트, 시어버터, 하이드로제네이티드식물성오일, 폴리솔베이트20, 솔비탄라우레이트, 스테아레스-20, 하이드로제네이티드레시틴
