Can you use Tretinoin with Sunscreen?
Yes. Sunscreen is the essential daytime partner for Tretinoin.
Why
Sunscreen does not interfere with Tretinoin. Many actives (especially retinoids, exfoliating acids and brightening ingredients) leave skin more vulnerable to UV damage, and daily broad-spectrum SPF protects the results you are working toward.
How to use them together
- Apply Tretinoin 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.
