The CONTOUR device delivers ultrasound with different depths depending on the desired treatment. The treatment principle is based on the use of focused ultrasound energy to stimulate the production of new collagen. This energy can reach a temperature of 65 to 75°C. The targeted cells are heated and destroyed on the face or body, which allows the skin to be re-tautened. The step-by-step technique: Emission of HIFU energy / Diffusion of fractionated energy deep down / Thermocoagulation in the deep structures (dermis and subcutaneous tissue) / Gradual production of collagen through the healing process during the following months.
