There are two types of energy-based treatments for vaginal rejuvenation. Both treatments use heat. Radiofrequency (RF) treatments: Electromagnetic waves are used in RF devices. Similar to the waves used in a microwave – but to a lesser extent – the energy is focused to heat the tissue. Brand names of RF devices include Geneveve by Viveve and ThermiVa. CO2 laser treatment: The laser heats up the upper layers of the tissue, causing the tissue in the lower layers to make more collagen. This makes the skin firmer and tighter. Brand names of laser devices include MonaLisa Touch, FemTouch and FemiLift.
