Among all procedures of laser dermatocosmetology, percutaneous laser coagulation of blood vessels is probably the most difficult to perform and risky. This is due to the fact that we have to coagulate a large object inside the skin at a high temperature (over 85&deg;C) so that the surrounding tissues are not affected (they coagulate at 60&deg;C). Of course, lasers have a selective effect, but never 100 percent. A doctor must take into account more than a dozen variables in order to effectively and safely solve the task of laser removal of blood vessels. If he makes a mistake somewhere, it will provoke complications up to scarring of the skin, which, unfortunately, is common.

Vascular pathology of the skin can be detected in the following cases: expansion of blood vessels (dilatation);

<ul>
	<li>narrowing of blood vessels;</li>
	<li>violation of the permeability of the vascular wall;</li>
	<li>violation of vascular reactivity.</li>
</ul>

Dilation of blood vessels is the only variant of the pathology in which laser treatment can be used.

<h2>Effect of laser on biological tissues</h2>

At least two processes are observed when the laser interacts with biological tissue.

The first is а&nbsp;physical process of converting light energy into a thermodynamic process of heating, which leads to a local increase in temperature.

The second is a chemical process when heated proteins are denatured, their native conformation changes. The amino acid sequence of the protein does not change.
