Sun-induced skin changes - liver spots; Senile or solar lentigo or lentigines; Skin spots - aging; Age spots
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.
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 health care provider usually diagnoses 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. The biopsy also helps rule out a skin cancer called melanoma, if you have a liver spot that looks irregular or is unusual in other ways.
Most of the time, no treatment is needed. Talk to your provider about using bleaching lotions or creams. Most bleaching products 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 sensitive people.
Talk to your provider about other treatment options, including:
- Freezing (cryotherapy)
- Laser treatment
- Intense pulsed light
Liver spots are not dangerous to your health. They are permanent skin changes that affect how your skin looks.

- Try to avoid the sun at midday, when sunlight is strongest.
- Use sunglasses to protect your eyes.
