numbuzin No.3 Pore Smoothing Serum
Ingredient analysis and how the ad lines read

Read on 2026-09-11
What is this product?
Reach for this numbuzin No.3 serum if you want a fermentation led pore and texture serum whose first two entries are bifida ferment lysate and galactomyces ferment filtrate, ahead of water at 5, and skip it if you are pregnant or avoiding retinol alternatives, because bakuchiol sits at 15. Niacinamide at 6 and adenosine at 19 sit behind a functional cosmetic filing, with kojic acid at 23 adding a second brightening route. There is no fragrance, no essential oil, no drying alcohol and no exfoliating acid across its 34 entries. One thing to know: the ingredient list here was published by the brand itself rather than read off a retailer, and the drugstore record matches it byte for byte.
What makes it different?
Two ferment filtrates occupy positions 1 and 2, ahead of water at 5, which is an unusual ordering that puts the fermentation story in the vehicle rather than in a trailing active slot. The formula pairs bakuchiol at 15 with niacinamide at 6 and kojic acid at 23, so it runs a retinol alternative and two brightening routes in one 30ml serum. The emollient is squalane at 10 with no plant oil or butter anywhere, which is why the comedogenic screen returns empty while four ester emulsifiers cluster at 24 through 27.
