If you want to lighten them without discoloring your skin then use lemon juice. There are 2 ways to do it, sometimes I do both. First, cut a lemon in half and rub the inside of the lemon in some sugar. Then scrub your face with the lemon/sugar. Or wash your face and then squeeze some lemon juice in a glass and apply to your face with a cotton ball. It will tighten up your skin and lighten age spots.
