A submental thread lift is a minimally invasive cosmetic procedure that places dissolvable medical sutures under the chin to reduce mild fat deposits and tighten loose skin. How It Works Material: Practitioners use PLLA/PCL resorbable threads. Fat Reduction: Inserting smooth or twisted threads physically disrupts fat cells beneath the skin, causing a process called lipolysis (fat breakdown). Skin Tightening: As the body slowly absorbs the threads over several months, it triggers a healing response that boosts collagen and elastin production. Types of Threads: Smooth threads are used in grids or patterns to stimulate collagen and melt small amounts of fat. Barbed threads have tiny hooks that physically catch and pull sagging tissue upward for an immediate lift. The Procedure Anesthesia: The practitioner numbs the area using a local topical cream or injection. Placement: Fine needles or cannulas guide the threads into the precise layer just beneath the skin. Duration: The entire treatment usually takes 30 to 60 minutes.Recovery and Aftercare Side Effects: Expect mild swelling, bruising, and slight tightness or tenderness for a few days to two weeks. Do Not Touch: Avoid rubbing or pressing your chin for at least 48 hours. Sleep Position: Sleep on your back with your head elevated for the first few nights. Limit Movement: Try to avoid bending your neck sharply or looking down constantly for the first week.
