Bit of a “horror film” in terms of function too. Most of these sorts of scams actually do nothing; the better to keep any consumer regulatory agency from waking up. This mask actually delivered shocks to the face (ref#8 here). There are (apparently) legitimate uses for “TENS” but just shocking your face muscles for the presumptive purpose of “beauty” ain’t one of them, sez this old biased one.
