I had Excel V laser to treat telangiectasias and that helped with some of them, but above on my nose there are many of them and that treatment I had 5 weeks ago. Is it normal that? They are very noticeable above on my nose. On my cheeks they have disappeared. I even had a crust post laser and that left me a scar on the tip of the nose. My dermatologist told me the telangiectasias could disappear with time. And on the scar, he says that should "raise". Is it true?
