Editor's Pick: When applying eyeliner, you can also dot this serum along the lash line—two steps done at once. Dark brown looks softer than black on the eyes, making it great for daily commutes or light makeup looks. It's also safe for sensitive eyes, won't tug at your eyelids when removing makeup, and glides on smoothly.
