You know you're serious about tanning when you hire a personal tanning assistant, and anyone who has seen Mariah Carey's dark tan over the past few years can easily tell that she loves to do it. This has led to more than a few instances of bright orange skin in the past, but Mariah has decided that gold is more her color now. She is working with her tanning assistant, who is from the Portofino Sun Center and Spa in Beverly Hills, developing a new fake tan line that is made with 24-karat gold dust. It sounds like it might be a little over-the-top for anyone who isn't spending a lot of time on stage, but it will probably be a hit with those who really like to look bronzed. Or gilded.

Idrolux makes a variety of innovative tanning lights that are designed to work while you shower. According to the company, the presence of water can increase the tanning effects of UVA rays by up to 30%. While there are panels that can be attached to existing showers, Idrolux Symphony, their premium model is the original Idrolux, which is a shower with the patented light panels built into it. The panels come four different colors and custom colors are available, so you can bathe yourself (while you bathe) in the light of your choice. In addition to the tanning features, the showers have a multi-function shower head and an optional massage jet. They all come with a remote control to control the lighting.

All the risks that are normally associated with sun exposure are not mitigated by use of an Idrolux, so the company recommends that exposure be limited to 10 minutes per day.
