You may not be aware, but your body needs light, or at least prefers it, to keep its systems running in a healthy manner. This is the driving idea behind a gadget like the Soft Laser Wand, which uses a specific spectrum of UV light to try to encourage your body to increase its rejuvenating efforts, such as wrinkle-reducing proteins and blemish-free skin. All you have to do is use the wand to laser your flesh twice a day for six minutes at a time.

The Soft Laser Wand sells for about $220, which, while that's far cheaper than professional laser treatments, might also be far less effective.
