Frequently Asked Questions (FAQ)
How does Numbuzin's numbered system help in choosing products?
Each Numbuzin number corresponds to a specific skin need: No.1 – moisturizing, No.3 – radiance, No.4 – collagen/firmness, No.5 – pigmentation reduction, No.6 – night renewal, No.9 – anti-age with NAD+. The system makes it easy to build an individual routine – you can choose one or several series according to your skin's needs.

NAD+ (nicotinamide adenine dinucleotide) is a vitally important cellular energy molecule whose quantity in skin decreases with age.
