The 3 on the bottle is not a strength and not a count of anything. numbuzin sorts its whole range by the concern each number answers: No.1 is the soothing number, No.9 the firming one, and No.3 is the pore and texture number. The carton puts the idea as a question along its side panel — what's your number?
The top of the list is where this one is unusual. Bifida Ferment Lysate is declared at 42 percent and Galactomyces Ferment Filtrate at 21 percent, and both are printed above the water, which does not turn up until fifth. Most serums lead with water. Here the two ferments are carrying most of the liquid themselves.
What follows is short enough to read in one go. Niacinamide sits sixth, squalane tenth as the emollient the name leans on, then sodium hyaluronate, panthenol and adenosine. Silk and goat milk extracts appear in the middle of the twenty-eight, which matters if you avoid animal-derived ingredients. There is no parfum, no essential oil and no alcohol.
The fluid itself is milky rather than water-clear, and spreads thin out of a glass dropper without leaving tack behind. numbuzin publishes a two-week measurement for pore area and for surface roughness; those two figures appear further down this page.
