What is the best way to remove green/blue veins on my face? I am a 25 year old female. Already tried sclerotherapy (Photo)

The veins that really bug me are the ones on my face. I've always had a green vein under 1 eye & a long green vein down the side of my face. I began treating them with sclerotherapy almost 2 years ago and a few thousand dollars later I can STILL see the veins. How can I get rid of them for good or should I just accept the fact that I can't? I think they have somewhat improved and gotten 'lighter'. The veins keeps me from having an even complexion as they make my skin look darker in that area.
