There was a tv program on the other night talking about this subject. The science behind skin lightening creams proved without a doubt that actually they do not work. The reason why is because all the cream does is make the skin more of an even tone. To answer your question, I have never heard of tablets that claim to lighten the skin, but if there are tablets I can guarantee that they would only work with lots of side effects. The melamine in your skin makes the color, if you mess around with chemicals to change the color then it can only have a bad affect on your body. My question is why would you want too? We are all different, and thats what makes us beautiful. The idea of lightening your skin tone, or even making it darker is just ridiculous. Beauty comes in all shapes and sizes, and so does skin color. Be proud of the skin you are in, thats what makes you unique.
