The Silk'n Tightra was developed to help you get over your insecurities about your vagina. It helps your intimate zone look better and helps you enjoy intimacy with your partner more. It also prevents light urine loss. The Silk'n Tightra uses special Bi-Polar RF Energy technology. It's technology that tightens and tones your intimate zone, both internally and externally. The technology also trains your pelvic floor muscles at the same time. The Silk'n Tightra features 16 gold and 3 chrome electrodes that treat your intimate zone both internally and externally. We recommend using the Silk'n TIghtra a maximum of 20 minutes a week. The Tightra also shuts off automatically after 20 minutes. You'll see visible results in just 4 weeks. Charge the Tightra before use with the included USB cable. Prior to use, apply the Intimate Gel to the Tightra, as it provides better conductivity for the electrodes. The Silk'n Tightra warms up automatically during use, and the 16 heat sensors adjust to your body temperature. The Touch sensor on the Tightra means the device only works when there's proper contact with the skin. The Movement Sensor also ensures that the Tightra doesn't get too hot and won't warm up if it's not sliding across the skin. The Tightra can be cleaned after use with toy cleaner and running water. Always make sure that the Tightra is turned off. Then store the device in the beauty case to prevent dust from accumulating. Caution: only use the Silk'n Tightra a maximum of twice a week, for a maximum of 20 minutes.
