Thread lift treatments are a non-surgical alternative to facelifts that involve injecting dissolvable threads into the skin to tighten it. The threads provide an immediate lifting effect and stimulate collagen, elastin, and hyaluronic acid production for continued tightening over time. Results can last 1-2 years. The procedure causes minor bruising or swelling that fades after a few days. Thread lifts can lift skin on the face, neck, arms, and buttocks.
