Vascular mesh on the legs - telangiectases occur inmorethan half of women, red spots Birthmarks - almost 2 percent of infants, hemangioma senile lips - at 4 per cent of older people. All of them need a beautician, armed with laser: only this device works on blizkoraspo of Proposition vessels without affecting the skin.A bit of physicsThe laser can destroy the blood vessels, because they have hemoglobin. Hemoglobin is the so-called chromophore - a substance that absorbs light energy. Transformed into heat, this energy and destroys the target tissue.In 1983, the wavelength (377 nm), which should work cosmetic lasers to deal with the superficial veins. Provedmoredifficult with the vessels located deeper-mi (eg, telangiectasia feet). These vessels require a greater energy density. In addition, the beam is pointed at them, could at Putnam destroy the other chromophore - melanin (it is contained in the skin and is responsible for its color).Lasers are the latest generation - with the optimally chosen diameter light spot, working on the principle of variable pulse - solved this problem. They gum up blood vessels without damaging the skin. The mechanism upon which the action of these lasers are very interesting. The fact that hemoglobin, which aims a laser beam - is a large concentration of the chromophore. A melanin - small beads. Therefore, the thermal effects of melanin, and manages to warm up and cool down, and the hemoglobin continues to heat up until not collapse completely.What you need to knowVascular "webs" can be tassted only the laser (laser photocoagulation), but not every laser for you. Diameter of light spot from your laser should not be less than 4 mm, the spectasm - yellow-green. And yet - the laser should be equipped with additional cooling of the skin.Promises are not guaranteed. It is impossible to predict how many sessions will disappear for a vascular defect.Vascular "cobwebs" are of two types: red and bluish venous capillary. Laser photocoagulation effectively fights with capillary telangiectasia, and sclerotherapy - with venous. An experienced physician must possess both methods.After the first session vascular spots may darken for a few days to becomemoreprominent. A good clinic will advise you the procedure for the rapid dispersal skoagulirovannyh vessels.To near extinct vessels has not appeared yet another "mesh", we offer five asles preventing telangiectasia.Sunbathe moderately, using sunscreen and common sense.Try not to stand and not sit for long periods, do not carry weight.Watch for the liver.Show your doctor if you are taking oral contraceptives.At the first sign of venous insufficiency, contact a specialist.Magazine "Family Doctor" № April 2001, the www.familydoctor.com
