The problem of hyperhidrosis or excessive sweating, which is relevant for a large number of people, is effectively solved using LASEST laser techniques. With the help of Nd: YAG Invasive laser radiation, the laser beam acts in a controlled manner on the most problematic areas of the body susceptible to hyperhidrosis and damages the most active areas of the sweat glands, which subsequently do not recover. A wide range of light guides and thin sterile needles, with the help of which the radiation is delivered, guarantees the accuracy and safety of exposure and makes the Nd: YAG Invasive laser scalpel the optimal laser for the treatment of hyperhidrosis. The destruction of the sweat glands by the LASEST medical laser is performed at a specified strict interval, because In general, sweat glands perform very important functions in the body and the use of non-professional lasers to treat them can lead to excessive dryness of the dermis or excessive sweating in other parts of the body (compensatory sweating).
