Can you bleach age spots on hands with peroxide?

Not with the stuff from the drug store..its only 3%. You need to buy peroxide from the beauty store that is normally 12%.

After you have applied the hydrogen peroxide to your age spots, you may feel a slight burning sensation for up to 10 minutes. This is normal and no cause for concern. Spots may appear white for up to four hours. After the white begins to fade, the spots may become pink or red for a few days. After several days, expect the spot to scab over for a few more days and then it should fall off on its own. Do not pick these scabs off prematurely or you will not see the full effect.

You can buy skin lightening creams instead of peroxide that work just as well.
