Thanks for your question. Mirvaso and laser treatments don't cause more veins to develop, but perhaps what you are seeing is a sort of uncovering or unmasking of veins that were hidden within diffuse redness. The Mirvaso can help with general redness, and most experienced laser specialists and dermatologists can treat the veins themselves with vascular lasers. It takes more than one treatment in many cases, so you will want to plan for a series of laser treatments to help improve the veins. Another option is fine needle hyfercation, in which a small, thin needle is attached to electrical current and placed right into a superficial vein. The current causes the vein to shrink down and temporarily dissapear, then it will gradually fade away in a few weeks. Ask your dermatologist about helping control your rosacea in general, and about hyfercation for your veins as another option.
