Microsclerotherapy is one of the most effective and well-established treatments for telangiectasia – or spider veins – an issue that affects up to 50% of all adults. Although spider veins can cause discomfort in some, for many patients, these small dilated blood vessels are an unsightly problem that they wish to have removed through procedures such as microsclerotherapy or laser therapy. Microsclerotherapy differs from sclerotherapy in that it uses micro-needles to specifically target telangiectasia, rather than larger varicose veins.
