THE CLAIM This galvanic energy device improves penetration of active ingredients, making the company's anti-aging serum 80 percent more effective. It can be used on the face or body.
THE EXPERT SAYS "By stimulating nerves, you can make a difference," says N.Y.C. dermatologist Doris Day, noting that aesthetitcians in Europ have been using galvanic currents for years to drive product into the skin. "It temporarily causes cells to swell, diminishing fine lines around the face. But something this small isn't going to work on a large area like your thighs."
OUR VERDICT Our faces looked tighter and more sculpted after using it, but the "lift" was temporary: By the next morning it was gone. The dimples on our thighs didn't budge.
