No special wait is needed. Apply Salicylic Acid first, give it a minute to absorb, then the other.

- Apply Salicylic Acid 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
Does waiting 20 or 30 minutes between products help?
We haven't found good evidence that a set wait of many minutes changes how most skincare works. The practical reason to pause is letting each layer absorb so the next one doesn't pill or sting.
