One of the best perks of my time working as beauty writer was getting to interview top celebrity dermatologists and sneaking in a question of what I should be using on my regular-person-in-her-30s skin. With all of the night creams, wrinkle creams, eye creams, and under-eye creams, every single dermatologist told me to stick to the basics: sunscreen for daytime and retinol at night. And it wasn’t just the dermatologists saying this. Nicole Kidman, Chrissy Teigen, and Jodie Comer have all endorsed it, too. Buzz Bissinger uses it every night. I was convinced.
