If it's too late for prevention and you don’t like your appearance you can do something about it. There are different treatment options:
There are bleach based medications that can lighten your skin. Bleaching lotions can cause blistering in some people so your doctor may advise that you also use a sunscreen to protect your skin from these effects.
Cryotherapy involves freezing your age spots with liquid nitrogen to destroy the pigment that makes them dark. After you have healed, your skin will be lighter.
Laser beams can kill melanin producing cells in your skin and should not damage it.
Applying acid to the age spots causes the skin to peel. Afterwards a new layer of skin will form.
