Is it okay to do a tattoo after a vein treatment?

It's important to have the treated vein heal before placing a tattoo needle over it. Your risk of infection and scaring and poor results is increased with the trauma of a tattoo placement. 

I would wait until the vein procedure is healed before getting a tattoo.  It may take a few weeks for your bruising   from the vein procedures to go away.  You don't want to have a tattoo on top of the vein procedure and risk infection in the area that you just had the veins treated in.  I would wait until the vein procedure is healed
