Hey,
I'm looking for a cream a soup or pills that lightens my skin.
I want my skin to be about 2 - 4 shades lighter.

Have you checked with your doctor,

Where do you live, in most areas these are prescription and can not legally be purchased without your doctor.

A person who would buy illegal drugs subject theirself to legal issues but also ending up with fake products and also damage to skin from problems with products.

Even when done properly many will do uneven lightening and few have lasting effects.
