Laser treatment of capillaries on face and nose itself is not complicated and is done on ambulatory basis without local anesthesia. The distal part of the laser handle is pressed against the skin, and after the activation of the laser with a foot switch, the light impulse is let through.
During the treatment of removal of capillaries, light turns into heat, and a blood vessel is closed and disappears. Liquid surrounding the vessel (tissue that contains a high percentage of water) does not absorb the light, preventing damage to the surrounding skin. Vessels are immediately ‘erased’ without the occurrence of repulsive peliosis (purple smudges).
Blood is heated, and a targeted capillary is narrowed and ultimately disappears. People usually feel only a small amount of heat. The treatment takes about 20 minutes, but it can be shorter and longer, depending of the severity of the case and the size of affected area.
