Both Reese Witherspoon and Matthew McConaughey Swear By This Product

In Wild, Reese Witherspoon plays a woman on a journey of self-discovery trekking through the wild alone. Reese looks relatively bare-faced in the movie, with the exception of some dirt and mud on her skin. But if you know anything about Hollywood, you know there was a lot of effort put into this au naturel look.

Reese's on-set makeup artist (and Academy Award winner for Dallas Buyers Club) Robin Matthews discussed how she and Reese prepped her skin for the movie, shared how she got Reese ready for the film, plus told us Matthew McConaughey's must-have beauty product. (Yes, he has one!)
