Chloë Grace Moretz has flawless skin, but the 19-year-old actress says it hasn’t always been that way. In an interview with Allure, Moretz says she had bad cystic acne when she was growing up. Now, she says her skin is acne-free thanks to Accutane and a healthy diet, but she points out that having skin problems “was a long, hard, emotional process.”

Moretz says she also works to keep her skin gorgeous thanks to an unorthodox facial cleansing method: She washes her face with olive oil. “I swear my skin is so much clearer because of it,” Moretz tells Allure.

It sounds weird, but Moretz isn’t the only one on the oil-cleansing bandwagon. Pinterest features several pins on olive oil face wash how-tos.

The American Academy of Dermatology recommends that people look for a cream or ointment that contains olive or jojoba oil to combat dry skin, but makes no mention of actually cleansing with it. But Gary Goldenberg, M.D., medical director of the Dermatology Faculty Practice at the Icahn School of Medicine at Mount Sinai, tells SELF that there is something to washing your face with olive oil—especially if you have dry skin or eczema.
