Cindy Crawford Sonia Kashuk Beauty With Benefits QVC for Cancer and Careers

Want to do good? Buy more makeup. (Yes, we're giving you a totally honorable reason for that 343rd eye shadow.)

Supermodel Cindy Crawford and makeup artist Sonia Kashuk have been close since meeting on a photo shoot in the '80s, and they're reuniting tomorrow in front of the camera for Beauty with Benefits, a QVC special that proves "a little makeup can make a big difference."

During the two-hour show, 80% of every purchase will go towards Cancer and Careers, a program established by the Cosmetic Executive Women Foundation that empowers women who've been diagnosed with cancer to continue thriving in the workplace.

If you've ever found yourself knee-deep in new products at Sephora (and, let's be honest, you totally have), you know that 80% of your cosmetics purchases is enough to make a major donation. Best of all, it's all stuff you'll actually want to buy. Proof? Participating brands include beloved names like Dior, Bobbi Brown, Tarte, Laura Mercier, Fresh, and other makeup and skincare lines you already know and love—and probably need to restock immediately anyway.

While this is Crawford's first time lending an impeccably manicured hand for the cause, Kashuk has been involved since Beauty with Benefits' inception three years ago. "When I was diagnosed with breast cancer, one of the first things to go through my head was, 'How do I help other women going through this disease?'" she told us. "I am blessed to have a wonderful platform to educate women on beauty, but how could I help to educate on an even more personal level? My involvement with Cancer and Careers has truly made a difference in my life. I am so proud of this organization and the work they are doing is stupendous."

The campaign has already raised more than two million dollars, but this year—especially with the involvement of one of the most iconic models of all time—they'll undoubtedly make a bigger impact than ever before. "Sonia and Cindy are smart, successful businesswomen who people look up to, as well as huge supporters of Cancer and Careers," says Carlotta Jacobson, president of CEW. "They both have a genuine connection to our mission: Cindy's close friendship gave Sonia strength and encouragement while she was facing breast cancer. Sonia's desire to keep working helped her feel more like the person she was before cancer. Cindy and Sonia want to help other survivors continue on the job, and have generously shared their story to talk about how Cancer and Careers can help."
