[sun spots vs freckles]: a comprehensive comparison of two common skin pigmentation issues
Sun spots, commonly known as age spots or liver spots, are flat, dark spots that appear on the skin as a result of long-term exposure to ultraviolet (UV) radiation from the sun. These spots are usually larger than freckles and can vary in color from light brown to black. They are more common in adults over the age of 40 and are caused by an overproduction of melanin, the pigment responsible for skin, hair, and eye color.
Freckles, on the other hand, are small, flat dark spots that appear on the skin due to sun exposure. They are usually smaller than sun spots and can appear in clusters on sun-exposed areas, such as the face, arms, and chest. Freckles are caused by genetics and can also be triggered by sun exposure, causing them to become darker or develop on areas of the body exposed to the sun.
