I have quite a few spider veins, some are larger more on the varicose size. I use MineTan self tanning foam. It gives me instant color that darkens even more over time. There are several shades to choose from so I went to their website and followed the guide to picking the right shade for me. The tans lasts long, not drying and it doesn't stink. I have used the Caramel foam and also the Violet foam. My next one to try will be the Olive foam. They seem to be forgiving as far as looking natural on my skin. The Caramel is more golden and the Violet is more brown. I think the tan makes my veins less noticeable, but it doesn't cover them completely.
