When it comes to skin goals, Jennifer Garner is a celeb that quickly comes to mind. She has radiant, age-defying skin - and luckily, she's not gatekeeping her secrets. The Alias actress revealed that one of her must-have serums is a $19 drugstore find that gives star-worthy results without the splurge. In an interview with Harper's Bazaar, Garner shared that she uses Neutrogena's Rapid Wrinkle Repair Retinol Serum "almost every night." Her go-to comes as no surprise since the A-lister has been the face of the brand for over 17 years . . . and she's been a fan since childhood. With skin that looks like it ages in reverse, her stamp of approval carries serious weight. See it! Get the Neutrogena Rapid Wrinkle Repair Retinol Serum for just $19 (originally $20) at Amazon!

"I don't know how they do it; it's such a magical product," she told Harper's Bazaar. Jennifer Aniston Has Been Carrying This $17 Lip Balm in Her Bag for Over a Decade The main reason for this uplifting feel? Retinol. Dermatologists swear by the serum's hero ingredient for transforming skin, which speeds up cell turnover to dramatically soften lines around the eyes, forehead and mouth. Best of all, the lightweight texture melts into the skin easily, leaving it feeling refreshed and silky. Additionally, the anti-wrinkle formula also features hyaluronic acid that adds moisture for a plumper appearance, while glycerin helps to strengthen the skin's barrier, keeping hydration in place. The result? A complexion that's soft, supple and luminous - the kind of healthy glow Garner is known for. Shoppers are catching onto this serum, too. One 50-year-old user says they "look ten years younger" because of the product, claiming that they have "zero wrinkles." Another buyer who's used it nightly for years said that it "shockingly removed" their fine lines. If you've been waiting for a sign to upgrade your anti-aging arsenal, this is it! Just look at Garner's luminous skin as proof of what's possible. Even better, the serum rings in at just $19, proving you don't need a Hollywood budget for high-powered results. See it!
