Liver Spot

A liver spot, also known as an age spot, senile lentigo, solar lentigines, or macula coriacea, is a flat, dark area on the skin that is usually caused by prolonged sun exposure. They are most common in people over the age of 40, but can occur at any age. The spots can range in size from a few millimeters to several centimeters and usually appear on the face, hands, arms, chest, and back. They are usually harmless and do not need to be treated. However, in some cases, they may be indicative of a more serious underlying medical condition and should be evaluated by a doctor.
