Skin lightening products
The AAD recommend some ingredients as being effective skin lighteners. These may take several repeat applications to prove most effective, but they can work to fade darker areas of skin.
Look out for products containing the following ingredients:

kojic acid
Both drugstores and online stores sell skin lightening products. Remember to check the ingredients before purchase.
