Illamasqua Hydra Veil Rehydrating Gel, $40; sephora.com.The Claim: Ever layer foundation over a parched complexion? Hello, streaks! Enter this water-based primer, designed to flood your skin with moisturizing glycerin and sodium hyaluronate along with botanical extracts to create an even, plump surface. Bonus: The formula keeps your base anchored for hours.
Expert Opinion: Most long-wear foundations are highly pigmented and settle into skin quickly, so they "get draggy" as you apply them, says makeup pro Troy Surratt. "But this gel-like primer gives the surface some slip to help your base glide on and blend easily." It's also a fantastic moisturizer for someone who doesn't like "a heavy cream under makeup," he notes.
Our Take: According to one tester, the application isn't exactly smooth. "It feels like I'm rubbing Jell-O on my cheeks, and it leaves a slightly tacky residue," she says. "But it does immediately make my skin look plump and dewy." During a 90-degree day in New York, this staffer decided to conduct an experiment, priming just one side of her face before applying her foundation. After six hours outside, "the half with primer looked fresh, as if I'd just put on my makeup," she says. "The skin on the other side was uneven and tired-looking."Read MoreLess
