Spider veins have many causes. Heredity, the hormone estrogen and possibly the hormone progesterone are thought to play a role. They are common in pregnant women and those taking birth control pills or hormone replacement therapy. Sclerotherapy (injecting a hypertonic salt solution into the vein) is still the gold standard for treatment of spider veins with maintenance treatments needed about every two years. It is safe and easy.
How can you be sure laser hair removal caused these spider veins? I was glancing through the
pubmed.com website and honestly could not find any research about spider veins being a side effect of laser hair removal, but maybe you could do some scouting around on the internet. BE SURE AND REPORT YOUR CONCERN TO YOUR DOCTOR. I don’t know if this will continue to be a problem if you continue with laser or if there is something else brewing underneath the skin totally unrelated.
Others may have experienced this, too, so hopefully they will come forward and explain. I haven’t heard of this before.
