Do sunscreen serums work?

Yes, sunscreen serums work as long as they are labeled broad-spectrum with an SPF of 30 or higher and you apply enough. The serum texture is simply a lighter base. It does not change how the UV filters protect your skin. The catch is that thin textures make it easy to under-apply, so use about a quarter teaspoon for your face and neck, and reapply every two hours in the sun. Day Drops SPF 50 is a serum-first mineral sunscreen with 25% micronized zinc oxide for broad-spectrum UVA/UVB protection. It also includes vitamin C and green tea polyphenols, blends in with no white cast, and is fragrance-free. Explore more in our sun care collection.
