The Miss Universe pageant airs tonight on NBC from the Mandalay Bay in Las Vegas, NV and America's eyes will be glued to the TV as we root for Miss USA, Rima Fakih. The event came under scrutiny recently when topless promotional photos were released which featured contestants covered with little more than carefully placed paint, but contestants have pushed through and are certainly getting down to their last minute preparations.

Breast augmentation is a popular procedure prior to competition. Carrie Prejean, former Miss California, famously had implants that were paid for by pageant promoters. Her implants later became a topic of controversy as pageant producers sued Prejean claiming she had never paid them back for the surgery. Augmentation takes months to heal fully, so any implant surgery would likely have been done months before contestants competed in their home country.
Other procedures popular amongst those preparing to step out under the hot camera lights is Botox for underarm sweating. One of the FDA approved uses of Botox is for treatment of hyperhydrosis or excessive sweating. Botox is used by celebrities to keep the pit stains away when stepping in front of the camera. Injections take effect in just a few days, so treatment could be done as recent as one week before the big night.
With every body part under the microscope, laser hair removal gets contestants ready for the spotlight in their bathing suits without worrying about embarrassing razor burn. Another useful tool for stepping out in a bathing suit is Velashape for cellulite reduction. When you step out under the bright lights and the eyes of the world, the last thing you want is dimpled skin. Both of these require several treatments to take full effect so they would likely be done 3-4 months prior to competition.
