Age and sun spots, also known as liver spots or solar lentigines, are flat, dark patches that appear on the skin due to sun exposure and aging. While these spots are harmless, they can be a cosmetic concern for many people seeking a clearer, more even complexion. Age and sun spots are hyperpigmented areas on the skin that typically develop on sun-exposed areas such as the face, hands, shoulders, and arms. These spots result from an overproduction of melanin, the pigment responsible for skin color, as a defense mechanism against UV damage. Over time, repeated exposure to the sun can cause these spots to darken and increase in number. Although these spots are generally benign, they can be treated with various procedures such as laser therapy, chemical peels, and topical treatments to restore a more even skin tone.
