Is pigmentation of the skin common after sclerotherapy?
Hyperpigmentation and sclerotherapy -
Sclerosing solutions used to obliterate spider veins and reticular veins can cause pigment deposition in the skin. How often does this occur? It has been observed in up to 1/3 of patients when hypertonic saline is used as the sclerosing solution, in 7 to 31 % of patients when polidochanol is used, and in 10% to 80% of patients treated with STS solution (sodium tetradecyl sulfate).
The good news is that pigmentation is usually temporary and rarely persists beyond 1 year.
