Molly Sims's Must Haves: From a Portable Charger to a Béis Travel Case

For an attainable glow that Sims can maintain year-round, she loves turning to her trusty YSE Beauty Skin Glow SPF 30 Sunscreen Primer ($48), even going so far as to say that she "doesn't leave the house" without it. "It is protective, hydrating, and above all gives me that soft-focus, healthy glow on my skin. It's everything you could ever need in a face product," Sims says.

Pro Tip: Per the brand, it's recommended that you apply a generous amount of this formula to your face and neck, and use it as the last step in your skin-care routine. The solution can be worn solo for a glowy look, or it can be used as a primer underneath makeup.
