Harmless vascular lesions such as ‘cherry angiomas’ or ‘spider nevi’ may appear on the skin with age. They are common and appear as bright red, slightly raised blemishes, mostly on the midrift. Most people aged over 30 years have at least one. There are a number of different treatments available including micro-sclerotherapy, which involves one of our Aesthetics Doctors injecting a solution to ´seal´ the blood vessel.
