Electronic muscle stimulation (EMS) is a physical therapy and fitness technique. Like TENS, it involves a machine that transmits electrical impulses through electrodes that are applied directly to your skin. Unlike TENS, though, the electrodes from an EMS machine are applied to key muscle groups. Electrical impulses are sent through electrodes placed on the skin near the targeted muscles. These impulses cause muscles to contract, mimicking the natural process of muscle movement and improving muscle tone and strength. The symmetry of the face is one of the most important features for the perception of attractiveness. Asymmetry of the face means that the right and left sides of the face are not identical. Subclinical facial asymmetry is very common in the general population. Most people have some slight facial asymmetry, and this is the normal biological situation in humans. Abnormalities from soft tissue, dental, and skeletal elements lead to facial asymmetry. Asymmetry has many causal factors, and its etiology includes both congenital and acquired conditions. Improve your facial symmetry, reduce the appearance of wrinkles and acne scarring. The electrical impulses that our Ricpind Microcurrent VFace FirmingDevice emits can improve muscle tone and strength in the face, which can help reduce the appearance of facial asymmetry. By stimulating the muscles on the weaker side of the face, EMS can help promote muscle growth and improve facial symmetry. In addition, EMS can also help improve blood flow to the facial muscles, which can further improve their strength and appearance. Product Includes : 1 Set XRicpind Microcurrent VFace FirmingDevice
