Spider veins, also known as telangiectasias, are small, dilated blood vessels that appear close to the surface of the skin. These veins typically twist and turn, resembling a spider's web, hence the name "spider veins". Other common synonyms used to describe spider veins include broken capillaries, thread veins, and spider nevi. Although they are typically harmless, spider veins can be unsightly and may make individuals feel self-conscious. Fortunately, there are various treatments available that can diminish the appearance of spider veins, including sclerotherapy, laser therapy, and radiofrequency ablation. It is important to consult with a medical professional to determine the best course of treatment.
