Jennifer Goldstein is the former beauty & health director of Marie Claire and co-host of the award-winning beauty podcast Fat Mascara. In her quest to uncover the world's beauty secrets, she’s gotten tattooed in New Zealand, dug up turmeric in India, harvested shea nuts in Ghana, and squeezed enzyme-rich eggs from salmon in Norway. She can pluck eyebrows like a pro and has read the FDA monograph on sunscreen labeling and effectiveness—but she still can’t get liquid eyeliner to look the same on both eyes.
