Liver spot
Liver spot
Liver spot (pronunciation: /ˈlɪvər spɒt/), also known as age spot or solar lentigo, is a common skin condition that occurs mainly in older adults. The term "liver spot" is actually a misnomer as it has no connection to the liver or liver function.
Etymology
The term "liver spot" originated from the belief that these spots were caused by liver problems. However, this has been proven incorrect. The term "solar lentigo" is more accurate as it reflects the fact that these spots are often caused by long-term sun exposure.
Description
Liver spots are flat, brown or black spots that usually appear on areas of the skin exposed to the sun. They vary in size and are most commonly found on the face, hands, shoulders, and arms. Despite their name, liver spots are not related to the liver or liver disease. They are harmless, but they can resemble cancerous growths.
Causes
Liver spots are caused by an excess production of melanin, the pigment that gives skin its color. This can be triggered by various factors, including aging and ultraviolet (UV) light exposure. They are more common in people over the age of 50, but younger people can also get them, especially if they spend a lot of time in the sun.
Treatment
While liver spots are harmless and do not require treatment, some people choose to have them removed for cosmetic reasons. Treatment options include laser therapy, cryotherapy, and dermabrasion. It's also possible to lighten the color of liver spots with skin-bleaching products.
Prevention
Preventing liver spots involves protecting the skin from the sun. This includes wearing sunscreen, protective clothing, and avoiding the sun during peak hours.
