I can see the blue veins through my skin. They are on my upper chest all the way under my arm and across my shoulders. I've been tanning (I know.. its bad) trying to cover it up. It works a little but they still show through the tan. I have olive skin too! Why can I see them? What can I do about it? ( On my arms I can't even find a good vein to give blood. (I keep trying though). Any advice or answers would be appreciated. Thank you in advance.

The reason you can see them in areas like the chest and face and tops of feet ect... is because the skin is thinner in those particular areas...the face is very vascular..theres nothing you can do about it ...its your skin type...
