Solar lentigo is a benign, hyperpigmented patch of skin caused by prolonged exposure to ultraviolet (UV) radiation. This exposure leads to local proliferation of melanocytes and an accumulation of melanin in the keratinocytes. Commonly known as “age spots” or “senile freckles,” solar lentigines are especially prevalent in individuals over the age of 40. These spots are frequently observed in sun-exposed areas such as the face and hands.
