Long pulse laser, good operation effect capillaries expansion

the capillaries expansion ( Telangiectasis) On skin and mucous membrane of superficial small blood vessels due to various reasons the persistent expansion, forming red or purple are mans porphyritic, dot, line, or damage. The capillaries expansion divided into two categories, primary and secondary; The former for unknown reasons, the latter is secondary to other known issues. In addition, healthy skin and mucous membrane can also occur blood capillary expansion. < / P>
< P> use long pulse Nd: YAG laser ( 532nm) Energy density in September: the operation parameters 18 j/cm2, flare 2 - 4mm,5ms- 30 ms pulse width, ready to ice cold, using 1 - at a place Three times, after the operation can see small ( Below 2 mm diameter) Capillary immediately disappear, larger blood vessels are solidified to a dark, after 1 - Three times after the operation, most of the blood capillary expansion. < / P>
< P> should be paid attention to for different USES different ways of operation, choice of different laser operation, and pay attention to the operation of deep, otherwise the surface of the stubborn. < / P>
