Thread veins or dermal flares affect many people, which is why most of them depending on the severity prefer to keep their legs covered up in the summer! These unsightly veins can be treated causing them to dissolve and disappear with minimal discomfort and zero downtime. Sclerotherapy is an established treatment for the safe and effective removal of these veins. Spider veins are like varicose veins but smaller. They are also closer to the surface of the skin than varicose veins. Often, they are red or blue. They can look like tree branches or spiderwebs with their short, jagged lines. They can be found on the legs and face and can cover either a very small or very large area of skin.
