Jenu Active-Youth Skincare system, $249; jenu.com.The Claim: This set relies on a slender rechargeable tool and high-tech topical eye and lip treatments to deliver smoother, plumper-looking skin in two weeks. Here's the scoop: Apply the products. Turn on the device and massage it over the areas for 60 seconds each. The wand emits ultrasound energy, which causes the microspheres inside the formulas to vibrate and "create channels in the upper layer of skin and lips so the other ingredients—like retinoids, hyaluronic acid, vitamin C, and peptides—can penetrate deep to do their job," says Colette Courtion, chief beauty innovator at Jenu Biosciences.
Expert Opinion: Dermatologist Joshua Zeichner believes that ultrasound waves can enhance product penetration. "After two weeks of nightly use, the skin around my tester's eyes was far more hydrated," and there was a moderate softening of fine lines.
Our Take: The gadget "tickles" and "feels like a massage," says a staffer who in 14 days reported "super-moisturized skin but only ever so slightly less visible crow's-feet." The tester notes the lip serum is "pretty greasy, but my mouth looks a bit fuller after just a minute of using the device." And, she says, the plump, hydrated effect can last for hours.Read MoreLess
