High-energy focused ultrasound reaches the vaginal SMAS layer directly, lifting the SMAS-fascia suspension and completely solving the problem of vaginal relaxation. lt precisely locates the energy of ultrasound at the 4.5mm fascia layer under the mucosa, which plays a role in the growth and pulling of muscles in the fascia layer,achieving the best effect of contracting the vagina. it acts on the 3mm collagen layer under the skin, reorganizing collagen,recovering the elasticity of the skin. At the same time, because the energy passes through the epidermis, there is no need to worry about the injury of the mucosa layer,and there is no need to worry about the infection caused by the injury of the mucosa layer! The operator inserts the probe into the vagina, and evenly acts on the SMAS layer in the vagina at 54-216 lines(about 1350-5400 points) to achieve the best effect of contracting the vagina.
