Thread Lift Information
Thread lift is a type of aesthetic procedure that involves inserting medical-grade absorbable sutures under the skin, typically used for adjusting facial or body contours. The sutures are medical devices approved by the Food and Drug Administration, and the procedure is a medical practice that must be performed by a qualified physician. Results and duration vary by individual and suture type. The following is a compilation of neutral public information, not medical advice.
General Principles and Common Suture Types of Thread Lift
Thread lift places absorbable sutures in the deep dermis. Besides physical support, literature also mentions that suture materials may induce surrounding tissue reactions; actual effects and suitability should be assessed by a physician. Common suture types include:
- Absorbable suture materials commonly include polydioxanone (PDO), poly-L-lactic acid (PLLA), polycaprolactone (PCL), etc., which are metabolized by the body over time.
- Sutures are classified by shape into smooth threads, barbed threads (with barbs), etc., with different uses and applicable areas.
- Sutures are medical devices and must be approved by the TFDA before use.
General Pre- and Post-Procedure Considerations
Thread lift is an invasive medical procedure. Treatment planning and precautions should be assessed by a physician based on individual conditions:
- Before the procedure, the physician typically evaluates skin laxity, facial conditions, and medical history, and explains suitable sutures and areas.
- After the procedure, swelling, bruising, or tightness may occur, varying by individual and treatment area; follow the physician's care instructions.
- Certain groups (e.g., pregnant or breastfeeding women, those with infection or inflammation at the treatment site, or allergies to materials) are generally less suitable or require special evaluation.
Conceptual Differences from Other Contouring Methods
Thread lift differs in principle from energy-based treatments and injectable fillers; indications and suitable candidates vary and should be assessed by a physician:
- Thread lift: uses absorbable sutures placed under the skin for support.
- Energy-based treatments (e.g., radiofrequency, ultrasound): use energy on different skin layers (see radiofrequency and ultrasound lifting pages).
- Injectable fillers (e.g., hyaluronic acid): add volume or improve depressions (see hyaluronic acid page).
Frequently Asked Questions
What is a thread lift?
A thread lift is an aesthetic procedure that inserts medical-grade absorbable sutures under the skin, typically used for adjusting facial or body contours. The sutures are medical devices approved by the Food and Drug Administration, and the procedure is a medical practice that must be performed by a qualified physician. This site only compiles public information, not medical advice.
Do the threads stay in the body?
Thread lifts commonly use absorbable sutures (e.g., PDO, PLLA, PCL materials), which are gradually metabolized by the body over time and do not remain permanently. Actual material, absorption time, and maintenance vary by product and individual condition; refer to the physician's explanation.
How long do thread lift results last?
Duration varies by suture type, treatment area, and individual condition, and because sutures are gradually metabolized rather than permanent. Actual results and whether to repeat the procedure should be assessed by a physician. This site only compiles public information and does not make efficacy claims.
Is thread lift regulated by authorities?
Yes. The sutures used in thread lifts are medical devices and must be approved by the Taiwan Food and Drug Administration (TFDA). The procedure is a medical practice that must be performed by a qualified physician. You may ask the clinic for the approval information of the sutures used. This site only compiles public information and does not endorse.
Is thread lift painful? What should I pay attention to after the procedure?
The procedure typically involves local anesthesia. After the procedure, swelling, bruising, or tightness may occur, varying by individual and treatment area. Physicians usually provide care instructions. Related sensations and management are medical matters and should be based on physician assessment and explanation. This site only compiles neutral public information, not medical advice.
How is thread lift different from radiofrequency or ultrasound lifting?
Thread lift uses absorbable sutures placed under the skin for support; radiofrequency and ultrasound treatments use energy on different skin layers. Their principles, indications, and suitable candidates differ. Whether a method is suitable should be assessed by a physician. This site only compiles public information.
