Why do my spider veins look like bruises?

The bruise appearance is a combination of multiple spider veins coming together. They only way to correct the problem is to treat the veins. Treatment involves injecting liquid into the veins to close them. Treatments usually last 20-30 minutes, and you may need three to four treatments to achieve results.

Local areas of vascular congestion from dilated reticular veins (which are a little larger and deeper than spider veins) can appear similar to a bruise, as they are both an accumulation of non-circulating de-oxygenated blood and usually appear dark purple in color, but do not fade with time. These dilated vessels can be treated with sclerotherapy injections in a vein clinic. The problem vessels will then be closed and can be reabsorbed by the body.

You need to be evaluated for this problem. There are several other possible reasons for the bruising.

Spider veins arise from different sizes and types of blood vessels; some appear more blue than others.
