Neon signs don't consume much power, but they look like they do. A cousin of fluorescent lighting, neon is actually quite energy efficient. A neon tube glows coolly when high-voltage, low-amperage electrical power excites the gas within it.
In order to have skin that glows and looks healthy and actually is healthy, you need to look at the whole picture and have a holistic approach to it. A lot of it is exercising regularly, drinking enough water, getting enough sleep, and keeping stress down.
Touch your lips just so I know in your eyes, love, it glows so Im bare boned and crazy for you when you come crash into me, baby and I come into you...
