Operating principle

The operation scheme of the alexandrite laser is indicated by the term selective photothermolysis. The laser acts only on the hair, without affecting the adjacent soft tissue. The light pulse is absorbed by melanin (the pigment responsible for color), is converted into thermal energy, heats and destroys the hair bulb. It dies at a temperature of 80 degrees, lower indicators only damage it, without interfering with the further growth of weakened hair.

Tanned skin, like dark hairs, contains a certain amount of melanin, therefore it also absorbs light impulses. When carrying out the procedure with such initial data, the risks of burns and damage to the surface layers of the dermis increase.

Frequency of

Alexandrite laser acts on the hairs in the stage of active growth, which is why it is realistic to remove no more than 30% of their total number in one procedure. To achieve the effect of absolutely smooth skin, a course of 4 – 10 sessions with a break from 5 to 8 weeks is required. Specific figures are determined by the cosmetologist for each patient individually. They depend on the hormonal background, the localization of the problem area and a number of other factors.
