4 High-Tech Beauty Gadgets That Really Work

Technology isn't just for the dermatologist's office anymore. At-home devices for beauty and skin care are becoming increasingly common. But sometimes we're just being sold battery-operated snake oil, and at iPod prices. Best to do your research, and be wary of grandiose claims. The products listed below are ones that have come through for me, providing noticeable results while costing less than comparable treatments at medi-spas.

Just remember, when combining technology with your skin care, always read the instructions! Some devices can do real harm if used incorrectly, and at the very least, you won't get optimal results.
