Did IPL/BBL cause a dark purple/ashen line and small holes/marks on the skin? (Photos)

A few weeks after my third treatment with 4-6 weeks apart I noticed a very straight ash/purple line that is completely out of nowhere. There was no blisters or burn after any treatment but that exact spot stung more than the rest. I also noticed more pockmarks. When I asked the doctor he said absolutely not related, said I probably just don't remember a vein being there (incorrect!!!!!!!!!!)and no point in future treatments because no reduction in smile lines.
