The Code Explained

What is the Regimen Code?

Every NIOD formulation carries a number from 1 to 3. The whole number is the step: 1. Prepares, 2. Optimizes, 3. Protects. The decimal orders products within that step.

Why does the order matter?

Applying low to high lets each layer absorb before the next. Lighter, active textures sit closer to the skin; richer sealing ones go on top.

How do I choose my codes?

Pick at least one formula from each step for a full routine, or build around a single concern. Any combination works - just apply the lowest code to the highest.
