52 and shining! I have been using Spotlight Oral Care for the past 3 years and product quiality and results have no changed at all; I am able to keep a natural white smile even though I an a coffee/wine social consumer. I use 2 x year the white strips 14 days treatment and on a daily basis 2 x day their toohpaste; it has no funy taste/odor .. I simply love it. Once you hit 50 years the teeth , as expected, tends to go yellow, but with this daily/2x year simple habit, I don't know what a yellow theet is, above this the ratio: price/quality is unique: very good quality products that does not change over the time. Higly recomended!
