There are very little details about the way that the Exoslim White Light Smile device works, but that can mostly be attributed to the fact that the device itself is actually quite straightforward and simple. Unlike competing brands, White Light Smile uses a solution that is not used by anyone else on the market today. Their solution contains 35% Hybrid Carbamide Peroxide, which has a natural whitening effect on teeth. With the use of this solution and the lighting system, your teeth will be pearly white in no time. http://drozforskolin.org/exoslim-reviews/
