Currently, the most demanded service in cosmetology centers is laser hair removal. But what should a laser device be like so that it can be called effective? Maybe it should be powerful? But for cosmetic lasers, there is a significant limitation on the power and intensity of radiation: above a certain threshold, it is too easy to burn the skin. And how to achieve a high speed of treatment of large areas of skin in the back, lower extremities, combining this with effective pain relief. After all, pain – the main cause of discomfort during laser hair removal.
A novelty has appeared on the domestic market of laser cosmetology devices, which implements a new, but already well-proven approach to pain relief and reduction of time spent on the procedure. We are talking about the LightSheer DUET device from the American company Lumenis. For many years he has been a developer exclusively in the field of hardware laser technologies for medical and cosmetic purposes, so his developments can be trusted.
The essence of the innovation is to create a negative pressure area under the handle, which leads to a dome-shaped retraction of the skin, the so-called vacuum enhancement technology. The mechanical effect of such a vacuum effect blocks pain impulses and is expressed in a decrease in pain during the procedure.
The novelty made it possible to move away from the limitation on the size of the working handle spot, which was dictated by the lack of the possibility of effective cooling: increasing the plate above a certain threshold does not provide sufficient contact cooling. The vacuum-strengthened handle is larger than conventional laser hair removal machines. Due to this, the processing speed of large surfaces is increased.
Pulling the skin to the source of laser radiation makes the absorption of energy by the melanin of the hair follicle more targeted, since the concentration of melanin in the skin decreases due to its stretching, and the "taking" hemoglobin energy is squeezed out of the underlying capillaries. In general, the process of laser hair removal improved in this way makes the procedure faster, more comfortable and better.
