Spider veins on thighs after pregnancy. They are too small to be treated with sclerotherapy. They are grouped together, resembling a bruise from a distance.
In our office we use aerolase neo, it removes small veins from any part of the body without much pain or downtime, 2-3 visits.
There are several lasers used to treat veins and vascular lesions. In our office we use the Cutera 1064 Nd yag. A pulsed dye laser would work as well.
