Can you use Niacinamide with Sunscreen?
Yes. Sunscreen is the essential daytime partner for Niacinamide.
Why
Niacinamide works well under sunscreen and is included in many sunscreens and daily moisturizers. It helps with redness and tone, while sunscreen prevents the UV damage that causes uneven tone in the first place.
How to use them together
- 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.
Who should be careful
Anyone using retinoids or acids should treat daily sunscreen as non-negotiable. If a sunscreen stings over freshly applied actives, wait a few minutes or switch to a mineral formula.
