i have always had quite thin skin that you can see veins through but i swear they are worse on my legs since having DC ( at yet another shit thing that happens post childbirth
)
fake tan used to cover them but it doesn't seem to do the job anymore :(
i have very good legs, long and slim but i am conscious about the veins :( strangely its only noticeable on one of my legs 
is there anything you can put on them or do to help? i would even consider paying for laser surgery or something. they are not spider veins, i don't have any of them, they are proper blue coloured veins.
