Diode laser

The principle of operation of a diode laser is to generate high power rays that heat the hair follicles. The wavelength is 810 nm. The destruction of the bulb occurs, the process of natural nutrition stops, and the hair itself brightens and thins.

At the time of ray generation, the skin is not injured, the degree of exposure is minimal. On the contrary, the diode laser procedure promotes the activation of skin regeneration processes, lightens pigmented areas, and smooths scars. Laser hair removal.

Laser hair removal (diode or alexandrite methods) has a general principle of exposure. Thanks to epidermal cooling, a specialist can use high fluences, reducing pain during the procedure.

There are several efficient cooling systems:

  • Contact. A transducer integrated in the tip of the tool allows you to cool high thermal conductivity. The procedure delivers less discomfort and is performed as painlessly as possible. A cooling transducer protects the epidermis by creating a heat sink on its surface.
