Using a tiny needle the substance called a sclerosant is injected into the vessels causing irritation and collapse of the small vessel. I use a device called a veinlite which helps to identify the veins below the surface of the skin and makes injecting more accurate.
As soon as the sclerosant is injected, the vein ‘disappears’ but reappears soon after. This doesn’t mean the treatment hasn’t worked as it takes time for the vein to collapse permanently.
Immediately after treatment the veins look red and angry however this settles after two weeks at which point it may seem as though the treatment has not worked at all – the veins look as they did before treatment. Don’t lose heart at this stage as this is normal. Three treatment sessions at eight-week intervals are recommended.
