Nars Afterglow Lip Balm ($28)

This moisturizing balm has a blend of antioxidants to help condition and protect lips, and Gross is a big fan. "It's so lush and silky on my lips and helps keep them hydrated year round. I also love that it comes in different hues to add just enough color," she says. While this popular shade, Orgasm, is described as a sheer peachy-pink with golden shimmer, there are eight other tones to try it in.
