No.9 is Numbuzin's anti-aging line, "firming and lifting" in the brand's words, and the number it has assigned to NAD+: a substance present in living cells that takes part in their energy metabolism. The brand sums up the line's formula in three words: NAD+, 50 peptides and PDRN. In the brand's own range the line includes a toner, an essence, eye creams and eye patches, a two-part lifting mask, a cream and a sunscreen. The routine Numbuzin gives for No.9: toner, then essence, then sunscreen in the morning or eye cream in the evening; the mask and patches are special care, and the brand pairs the eye cream with patches laid over it.
