Thread lifts work by inserting small threads into your facial skin in strategic areas. These threads stimulate collagen to rejuvenate your face and provide you with a more youthful look. A local anesthetic may be necessary in some cases, but many patients can receive a thread lift without any anesthesia. After the needles with the threads are inserted, the needles are withdrawn, and the threads remain in place. The entire procedure takes about 30 minutes.
