I really want to tell you to embrace your natural complexion. If you do want to lighten your skin, I would like to give you reasonable expectations. The foremost recommendation is to avoid the sun to the areas you want to get lightened - apply daily sunscreen with spf 30. There are other options to lighten skin tone including lasers, bleaching creams, and chemical peels. You should have a consultation with a board certified dermatologist to discuss which option is best for you.
