Since they were first available for home purchase, vibrating devices have been advertised as being "invigorating" for the complexion. Even today, personal massagers are sold with their boxes claiming that they're for giving you "a softer, healthier and happier complexion".
Now, obviously, this is mostly to disguise the fact that these things are being sold and used for sexual purposes. But is there any truth to this at all? Many of them show pictures of women using the things on their faces and even come with special attachments for facial massage. Does a facial massage with a vibrator actually help your skin in any way, or are you just knocking your brain around in your skull?
