With the help of a special partially shielded cannula needle and a probe that transmits the set energy, “ACTIVE” is able to determine a complete restructuring of the entire dermis of the treated tissue with absolute precision. The ability to directly manage thermal energy in a controlled manner in the selected district, with a preset and controlled temperature in order to induce the desired changes, allows for extraordinary results. In fact, with a temperature of about 50° C, the passage of the needle produces a denaturation of the primary, secondary, and tertiary structure of the protein structures resulting in both the retraction of the collagen fibers of the dermis with a lifting effect and the metabolic activation of the fibroblast, which repairs both the heat-damaged collagen and an increase in the thickness of the dermis with the neoproduction of new collagen. Around 60° C it exerts a defibrotizing action with the natural elimination of tissue adhesions resulting either from trauma such as fractures with abnormal tissue retraction, or post-surgery such as for scar reduction. Around 70° C results in cell lysis of adipocytes with the release of triglycerides into the interstitial spaces and extracellular matrix, where they are then subsequently removed by lymphatics. In this case, the alteration of the adipocyte structure makes it possible to perform an extremely precise and meticulous superficial liposculpture in all those areas that are extremely difficult to treat, an example for all the supraioid fat accumulation or the angle of the jaw.Through a special thermal camera, during execution the temperature increase of the treated area is continuously monitored by visualizing the values on a display. In this way, with millimeter movements it is possible to reach the desired temperatures and achieve the preset results. The treatment is specifically indicated in addition to its face and neck lifting effect, to achieve visible breast elevation, recompacting and uplifting of the buttocks, firming of the arms and belly, elimination of double chin to revitalize scars, and reduction of stretch marks.
