Liver spot

Liver Spots

Liver spots on the skin, often resulting from sun exposure.

Liver spots, also commonly referred to as age spots, are flat, brown, black, or gray spots on the skin. They are a common sign of skin aging and are usually caused by years of exposure to the sun's ultraviolet (UV) rays.

Overview

Liver spots are larger and more defined than freckles and typically appear on areas of the body that have had the most sun exposure, such as the face, hands, arms, back, and feet. Despite their name, liver spots are not related to liver function or liver disease.

Causes

The primary cause of liver spots is:

• Long-term sun exposure, which accelerates the production of melanin, leading to the formation of these spots.

Other contributing factors can include:

• Aging skin, as they are more common in people over 50, though younger people can get them if they spend a lot of time in the sun.
• Tanning beds, which also emit UV rays.

Prevention

To prevent liver spots, it is recommended to:

• Use a broad-spectrum sunscreen that protects against both UVA and UVB rays.
• Wear protective clothing, such as hats and long sleeves, when in the sun.
• Avoid peak sun hours, typically from 10 a.m. to 4 p.m.

Treatment

While liver spots are generally harmless and do not require medical treatment, some people choose to have them removed for cosmetic reasons. Treatment options include:

• Laser therapy
• Cryotherapy (freezing)
• Chemical peels
• Dermabrasion
• Prescription skin-lightening creams

Diagnosis and Consideration

It's important to differentiate liver spots from other skin conditions, including malignant melanoma, a form of skin cancer. Regular skin checks by a healthcare professional can ensure that any concerning spots are properly evaluated.
