Elizabeth Olsen has long been admired for her fresh-faced, glowing skin - the kind that looks effortlessly perfect without a trace of heavy makeup. And according to the actress herself, that's no accident. In an interview with InStyle, Olsen shared items in her beauty travel bag, including the RMS Beauty Supernatural Radiance Serum SPF 30. "It's the only makeup I use, basically, for my skin, because [the pink one] cuts the red out in my skin, and it also has a lot of sunscreen," she said. The multitasking formula offers sheer coverage, a natural glow and reliable SPF protection in one step.
