Laser Spider Vein treatment with Cutera Excel V+ advice? Had consultation and was told I could bruise and such (Photo)

This is for spider veins on my legs and face. The face is around the corners of my nose and on the bridge. They're not too bad so I decided to hold off on that as the face area makes me nervous. But on I'm scheduled to have my legs done. The back of my right leg behind my knee and a few other areas. It went well but with my anxiety I worry. I was told I'd probably bruise and what to expect. But I get scared of anything permanent. So any advice plus can I put anything to help it along on?
