Why can surface laser be used to treat varicose veins?
A laser that is applied from the surface of the skin can only penetrate a tiny distance before it loses its energy. External lasers can be used to eliminate small caliber “broken capillaries” on the surface such as those that commonly appear around the nose, but they rarely do as well on the legs. Even very small leg veins usually have larger feeder veins that must be injected before the smaller veins can be treated successfully.
