What's the best whitening soap u can recommend?

Soaps do nothing. They are a novalty and that's it. A waste of money. Think about it. You make a lather which dilutes the actives in the cream. Then you don't even leave the soap on long enough for your skin to absorb the actives before you rinse. Just use any old soap to clean your skin, use a peel (acid, microdermabrasion, enzyme, retinol, retin A... ), then use a cream.

I have to admit. You can't get much whiter than me. Why would you want to change something so beautiful. G-d made you the way you are for a reason.
