The Best New Beauty Gadgets

Dermatologists weigh in on the efficacy of at-home beauty devices that promise to treat wrinkles, blemishes, and unwanted hair.

For Exfoliating

Attach a single-use puff containing ultra-fine aluminum oxide crystals to the Neutrogena Healthy Skin Rejuvenator and massage damp skin to remove dead cells. “It makes your skin glow by smoothing its surface,” says Dina Yaghmai, a Chicago dermatologist. It may also help topical skin treatments that you apply afterward (like retinol) to penetrate more deeply, says Linda K. Franks, a New York City dermatologist. Use it up to three days a week (avoid it if you have severe acne or rosacea).

To buy: $40 at drugstores; comes with 12 puffs.
