Many small red blood spots on the body may be blood moles or purpura. If it is a blood mole, most of them are small blood spots that are isolated and scattered. When pressed, these small blood spots will show a decrease in color. Therefore, such small blood spots usually do not require treatment. For aesthetic reasons, they can be treated with laser or ionization. If such small blood spots are concentrated in a certain area and do not fade when pressed, it may be purpura, which is more commonly known as allergic purpura.
