They just show up, and near the surface of the skin is somewhere for them to go. As we age, we grow more and more of these fine vessels through a vascular growth process called angiogenesis. At the same time we lose fat and the skin becomes more translucent as the years go on, so these arterials become more evident.
People with hay fever and allergies tend to have more irritation around the nose, and this might cause extra blood vessels to grow there. Genetics is a factor, and sun damage makes them worse by dissolving the collagen around the vessels that usually camouflage them and by causing inflammation, which revs up angiogenesis.
