I'm always shocked when someone reminds me that Jennifer Garner is over 50. It's not a high-end, multi-step skincare routine that keeps her glowing. The actress keeps her regimen simple with drugstore products, and one specific three-in-one serum is the secret to her ageless complexion. Garner dished to Real Simple that she starts every morning by slathering on the Neutrogena Ultra Sheer Face Serum Sunscreen Broad-Spectrum SPF 60. "It does a lot of things at once-it's a primer, a moisturizer, and a sunscreen-we love a multitasker," she said.
