Do you mean that you can see the veins more pronounced through your skin or can you see them due to a difference in color i.e. varicrose veins? There are several new techniques to reduce greatly or eliminate the discoloration with lasers. I have no idea of the costs however.
You might want to consult your MD and see what he or she says. I'm sure they could point you in the right direction. Like I said I have no idea of the costs involved but it is definitely a correctible problem. I know I haven't been much help but I wish you the best on this!
