EMS is a form of therapy thatstimulate muscles and promote muscle growth, strength, and healing. EMS works by sendingelectrical impulsesthrough electrodes placed on the skin near the targeted muscles. These impulses cause the muscles to contract, mimicking the natural process of muscle movement and helping to improve muscle tone and strength. It can be used tohelp strengthen weak or injured muscles, as well as to enhance muscle growth. Microcurrent facials are a non-invasive cosmetic treatment thatuses low-level electrical currentsto stimulate the facial muscles and improve skin tone and texture.The treatment helps deliver small electrical impulses to the facial muscles and tissues,promoting cellular rejuvenation and collagen production. Our EMSculpt Sleeping V-Face Beauty Device help stimulates the muscles and tissues beneath the skins surface. This can help toimprove facial contours, reduce the excess neck fat,so as to re-contour and restore the sagging deep layers and fat to make them more harmonious with the rest of your face. Its common for people to have some degree of facial asymmetry, and its rare for anyone to have a completely balanced face. According to a2015 study ( National Library of Medicine ),facial asymmetry is common in the overall population. It can be caused by a variety of factors, including :aging, trauma, habitual sleeping posture, muscular imbalances, dental problems, and medical conditions such as stroke. The electrical impulses sending by our EMSculpt Device canimprove muscle tone and strength in the face, which can contribute to reducing the appearance of facial asymmetry. By stimulating the muscles on the weaker side of the face, EMS can help topromote muscle growth and improve facial symmetry.Additionally, EMS can also help to improve blood flow and circulation to the facial muscles, which can further enhance their strength and appearance. âRemove Excess Neck Fat âRe-Contour a V-Shaped Face âCorrect Facial Asymmetry âEnhance Muscle Growth âFirming & Lifting Loose Skin âEMS Vibration Technology âStimulates Muscles Tone and Definition Hook the ends on your ear like a mask Make sure the two nubs are facing inwards and firmly pressing against under your chin.
