The gold standard for spider veins is sclerotherapy, not laser. Sclerotherapy is an effective procedure where a solution is injected into the vein and causes the vein to close and disappear.
Using a tiny needle, a sclerosing solution called Asclera is injected into your spider veins, causing them to collapse and eventually fade within several weeks. Patients describe the sensation as mild stinging and cramping but the discomfort is well tolerated. Mild temporary bruising may occur after the treatments. A rare side effect is hyperpigmentation, which usually resolves eventually over months.
