The mom of two posted a split of two selfies, captioned "most glamorous transformation." The first shows her without a stick of makeup, looking fresh-faced and gorgeous, and the second an equally pretty shot of her working a smoky-eye look backstage, dressed in a robe.
Paltrow is a face of Max Factor makeup, and the snap is her take on the brand's #GlamJan campaign, which asks beauty fans to show off their most glamorous transformation in support of their new ads featuring Norma Jean's transformation to Marilyn Monroe.
This isn't the first time Paltrow has gone bare-faced on Instagram—she promoted #WorldWaterday last year with this natural snap.
It's definitely refreshing to see stars reveal their before and after makeup snaps—but will you get on board with Max Factor's #GlamJan campaign too?
