Is it anyway or medics or even technique to make my skin lighter?

Don't do it: It's unfortunate that some communities are still so backwards as to judge you by your skin color. In the usa this is considered the lowest form of ignorance & stupidity. But even if you are among such people, don't try to lighten your skin with any of the available products -- you are likely to disfigure yourself. Build and trim ur muscles instead to look good in tomorrow's more enlightened world.
