Does anybody know what this skin condition might be?

I have tiny little blood capillaries that are really close to my skin mainly on my face, tops of my arms, and knees. They are all pretty small, about the size of a freckle. I know is is not anything on top of the skin, but something with my veins. This condition has always made me feel insecure about myself because at a quick glance it appears that I have bad acne. When I press on the skin where the capillaries are, or pull the skin tight, they disappear and then reappear when the skin goes back to normal. I have had this since I was born and I am now 23. I don't think it could affect my health, but since I have never had it diagnosed I guess I really don't know if it could or not! I have been to several dermatologists in the past and none know what it could be. I would like to know if anybody else has this, knows what it is, or know if there is a way to treat it. Any information would help. Also include web sites if possible. I do know that it is not Rosacia.
