No special wait is needed. Apply Niacinamide first, give it a minute to absorb, then the other.
The routine
- Apply Niacinamide as directed (if it is a night-time active, use it in the PM).
- In the morning, finish your routine with a broad-spectrum SPF 30 or higher as the last skincare step.
- Reapply every two hours when outdoors.

FAQ
