Thread veins around nose InstaVein lasered but now purple and look worse - should I have another round or leave it? (photo)

When I was pregnant I developed a burst blood vessel on my nose and my cheek. I recently went to get them lasered using something they called InstaVein and at the time the Dr said I’ll do the ones around your nose too. It’s now four weeks later and the small blood vessel spots have gone, but the veins around my nose have gone purple and lumpy and look worse than before. I contacted them and they advised another session for free, but I don’t want to make them look even worse. What should I do?
