Are my blue temple veins are these normal and treatable? (Photos)

These veins are generally considered harmless, unless you have headaches, visual changes, etc for which you should see your Primary Physician and possibly a specialist.  Generally, they become more prominent as we age and have loss of tissue volume.  Treatments such as removing them or injecting does come with some risks that can be serious, as does filler.  Thus, we recommend ignoring them or injecting small amounts of filler near the vessels, with a well-trained provider, to fill in the loss of volume. 

These veins are completely normal. If the area is throbbing or you are having regular headaches you should consult your primary doctor. However if cosmetically more apparent, I would leave alone at this time. If the issue worsens considerably you can consider a small procedure to remove the vein.
