Venus Legacy radio frequency skin tightening uses Multi-Polar Radio Frequency and Pulsed Electromagnetic Fields to produce heat under the skin’s surface. This process helps to naturally increase collagen and elastin fibers, while also shrinking the volume of fat cells. At the same time, an adjustable pulsed suction (called VariPulse™) on the skin-tightening machine gently works to pull the skin upward, allowing the energy to travel deeper and providing more comfortable and effective treatment. Venus Legacy is safe for all skin tones, even darker ones.
