Olympic Medalist Chloe Kim Swears By These Products, Including a $14 Lipstick

Latisse Eyelash Growth Serum ($46/month)

Kim's best-kept secret as of late? This eye serum. "I'm going on a journey right now," she says, noting that she recently got rid of her extensions and has been using Latisse to enhance her lashes, applying the serum nightly.

Pro tip: Latisse is a prescription-only serum and should be taken under the advisement of a medical professional.
