Extended data:
Senile spot, called senile pigment spot, is also called seborrheic keratosis in medicine. It refers to a kind of lipofuscin patch on the skin of the elderly, which belongs to benign epidermal proliferative tumor and generally appears on the face, forehead, back, neck and chest. Sometimes it may also appear in upper limbs and other parts. Most of them begin to grow after the age of 50, which is more common among the elderly. People also call it "longevity point".
The results of modern medical research show that this nickname is not true, and it is not a sign of longevity. Experts found that with the increase of the average age of the population, senile plaques are not common among the elderly, accounting for only 27%.
