the most common side effect is hyperpigmentation and this can be reduced with stockings (compression) and the use of topical creams and Scler-X (see link).

Every medical procedure has risks. I would have the sclero done by a board certified vein surgeon who understands the subtleties of the procedure.

Sclerotherapy and side effects.

As with any procedure there are side effects associated with sclerotherapy. The incidence of side effects is usually related to the experience of the injector.  There are more common side effects such as bruising and swelling and less common such as staining and matting.  Most side effects can be easily treated and the overall results of sclerotherapy are very good.

Sclerotherapy kills the vein and causes it to become a scar.  It is a scar underneath the skin and it will take time to disappear.  It takes longer in women of color, but it should eventually disappear.  It gets better with time.

Although sclerotherapy is a great procedure for the treatment of spider veins, there are a few risks that you should be aware of before proceeding with treatment.  Some of the risks include hyperpigmentation or staining of the skin over where the vein was injected.  This is more common in patients that have a darker skin tone.  Matting is when closing down the vein causes dilation of surrounding capillaries overlying the vein.  This usually goes away with further injections.  Also patients can form a blister of the overlying skin which in severe cases can cause scarring.  Other common side effects include bruising, and lumpiness over the injected vein that can take a few weeks to a few months to resolve.

first and for more the veins can recur.   There is a change for brown staining at the injection site.   And rarely there can be skin breakdown.  Blood clots or injection material going to in intended vascular locations.

First of all, injection sclerotherapy is the gold standard, best treatment for spider veins in the legs.The most common "side effect" is hyperpigmentation.Hyperpigmentation is a dull brown discoloration that may occur in the skin overlying about 10% of treated spider veins. Pigment can last for weeks or months and about 99% of pigment is gone in 12 months.Pigment is hemosiderin which are small iron particles in your blood that cause the dull, rusty brown color.
The worst "side effect" or complication of spider vein sclerotherapy is ulceration. This is extremely uncommon and unpredictable and occurs in about 1:1000 patients. A dime size wound may develop over a sclerotherapy injection site that may take months to heal and usually creates a small scar. If the scar is cosmetically disturbing it can be excised/removed by a plastic surgeon.
