Speed - It doesn't take all day to get a tan indoors. Depending on your skin type, just a few minutes, not hours. Maintain your tan for as little as 60 minutes a month. Control - Our state-of-the-art equipment allows us to monitor and scientifically control your ultraviolet UV-A and UV-B exposure. We make sure you tan and don't burn. Climate - Overcast, rainy, or 109 degrees in the shade, you never have to worry about the weather with your pleasant, climate-controlled environment.
