Age spots are the flat brown, black or yellow spots that appear on the neck, hands, and face. They are primarily caused by sun exposure and usually start to appear once people hit 40. Age spots are not dangerous in any way, so there is no medical reason to get rid of them. However, they can reveal a person's age, so many men and women want to remove them for aesthetic reasons. You can get rid of age spots using a number of different methods: using home remedies, or using professional skin treatments.
