NAD+ — Nicotinamide Adenine Dinucleotide — is a coenzyme that plays a central role in cellular energy production, DNA repair, and the metabolic processes that keep skin functioning at its best. numbuzin built their hero product around it when most brands were still mentioning it as a supporting ingredient.
The No.9 Essence delivers NAD+ alongside collagen, peptides, and adenosine in a formula designed for the skin's daily renewal process: firming and lifting through consistent use rather than through a one-time visible effect. It also works on the post-inflammatory hyperpigmentation that follows breakouts — the marks that are harder to shift than the spots themselves.
Use morning and evening as your essence step. Give it six to eight weeks. The results arrive quietly but they arrive clearly.
