Sunscreen is a beauty-editor obsession. (What other product helps stop skin aging?) This one blocks UV rays with micronized zinc, which is gentle enough for sensitive skin and can even help minimize inflammation. It can be worn alone (it doesn’t leave a white residue) and also works beautifully under makeup. Another editors’ favorite: Skinceuticals Physical Fusion UV Defense SPF 50 ($32, skinceuticals.com), which is infused with a subtle tint to even out your skin tone.
