How successful is sclerotherapy?
The injections are almost painless and all the thread veins can usually be treated in one half hour session. They look worse to begin with and large vessels may go black. Fading starts after three weeks and it will be three months before the main benefit is seen and improvement continues for a year. For this reason it is a good idea to plan treatment some time before your holiday. The treatment will last for several years, but other thread veins will often develop over time. An improvement of 80-90 % is more usual.
