Can you wear SPF foundation or tinted sunscreen over your regular sunscreen—or does layering reduce your protection?
One small but fascinating study looked at exactly that.
Researchers tested different SPF layering combinations using sunscreen, cushions, foundation, and powder. Even when participants applied less than the recommended amount of each product, the layered combinations still showed an additive effect for UVB protection.
What does that mean?
It suggests that layering SPF makeup over sunscreen doesn't appear to disrupt your protection and may even boost it—as long as you're still using sunscreen as your primary source of SPF.
Our biggest takeaway:
Your sunscreen should always do the heavy lifting. SPF makeup is a nice bonus, but it shouldn't replace a proper sunscreen application.
