Today we're reporting live from Cosmoprof North America, a trade show for beauty manufacturers and distributors, and one that would make any beauty junkie squeal with delight -- we're talking miles of flat irons, nail polish and anti-aging skin care lotions and potions.

We're here to scope out the latest technologies and beauty product innovations to see what hot-off-the-conveyor-belt products shouldn't be missed. So, for the next five days we're going to debut a "best in show" product. First up: Solerra Tanee Tan Line Corrector, $5.99.

This genius tiny tube of self-tanner has a sponge tip applicator that makes it super cinchy to hide dreaded tan lines. You squeeze the little lip balm-sized tube and the sponge becomes saturated in self-tanner. You then apply the tanner to your lines, blend slightly and let dry. Hours later your tan lines will look less obvious.

Quite nifty, and at such an affordable price point, you should have a tube stashed in your bathroom, so when those emergency tan lines appear -- and you have to be photographed in that strapless -- you'll be covered -- literally.
