What do age spots look like?

Age spots, also called solar lentigines or liver spots (though they have nothing to do with the liver), appear as flat, brown spots on areas of skin frequently exposed to the sun, such as the face, hands, arms, and shoulders. They are usually small, ranging from a few millimeters to a centimeter or more in diameter. Their color can vary from light brown to dark brown or even black. The edges are typically well-defined and the spots themselves are usually smooth, though they may sometimes appear slightly raised. They're generally harmless, but their appearance can be a sign of cumulative sun damage.
 

Age spots, also known as solar lentigines or liver spots, aren't a single type, but rather a collection of similar skin discolorations caused by sun exposure. However, they can be categorized in a few ways:

• Based on appearance: They vary in size, color (ranging from light brown to black), and shape. Some may be flat, while others might be slightly raised.
• Based on cause: The primary cause is cumulative sun exposure (UV radiation), but other factors can contribute to their appearance, making precise categorization challenging.
• Based on medical terminology: While age spot is the common term, the medical term solar lentigo is more precise, reflecting the sun's role in their development. Other related terms might be used depending on the specific appearance and characteristics.

Therefore, there isn't a simple list of "types" as with some other medical conditions. The variations in appearance are more of a spectrum than distinct categories.
