Though the fight against wrinkles went high-tech a long time ago, new technologies such as pulsing heat, LE.D.s and electrical currents have become safe and easy enough for consumers to use themselves, from home.

It used to be that slathering honey on your face and patting slices of cucumbers on your eyes defined an at-home pampering facial.

Not anymore. The “Baby Quasar,” a skincare tool promising even, clear and firmer facial skin can be purchased for several hundred dollars.

NuFace, a device emitting microelec-trocurrents will run you $450. But do these face-zapping machines work? Doctors question the effectiveness of self-treatment devices.

“One of the major issues with these home-use devices is they promise more than they can deliver,” says Dr. Arielle Kauvar, a dermatologist and associate professor at New York University School of Medicine.

Before you purchase one of these tools, consult with your dermatologist. [sources: The New York Times, FitnessRX]
