Liver spots are flat, brown or black spots that can appear on areas of the skin that are exposed to the sun. They have nothing to do with the liver or liver function.
Sun-induced skin changes - liver spots; Senile or solar lentigines; Skin spots - aging; Age spots
Liver spots are changes in skin color that occur in older skin. The coloring may be due to aging, exposure to the sun or other sources of ultraviolet light, or causes that are not known.
Liver spots are very common after age 40. They occur most often on areas that have had the greatest sun exposure, such as the:
- Backs of the hands
Liver spots appear as a patch or area of skin color change that is:
- Light brown to black
Exams and Tests
Your doctor will diagnose the condition based on how your skin looks, especially if you are over 40 and have had a lot of sun exposure. You may need a skin biopsy to confirm the diagnosis if you have a liver spot that looks irregular.
Most of the time, no treatment is needed. You can improve the appearance of your skin by using skin bleaching lotions or creams. Most bleaching lotions use hydroquinone. This medicine is thought to be safe in the form used to lighten darkened skin areas. However, hydroquinone can cause blisters or skin reactions in some people. See your health care provider before starting treatment if you are concerned.
Freezing (cryotherapy) or laser treatment can be used to destroy the liver spots.
Liver spots are not dangerous to your health. They are permanent skin changes that affect how your skin looks.
