An allergic reaction is rare for us in treating small veins. I can't remember a single case of allergy, since 1983, from treating small veins because the medication is so dilute. That's not to say it is impossible, but the chances are small. Allergy is more likely in treating the larger varicose veins where the concentration of the medicine is greater and the volumes are larger. You will discover that many of our staff, including the nurses, have had this treatment not only to their legs but also their hands, face and even to the veins around their eyes.
Some women have dark circles under their eyes.
They are more common as you get older, and are usually a condition of women. These patients have feeder veins coming from their scalp that drain into the veins under their eyes where the blood collects and distends those veins, making their eyes darker. We can see the feeder veins at the upper front temple regions. Treatment of these veins can markedly reduce or eliminate these dark circles. Don't even think of it.
