How Thread Lift Works

A thread lift procedure takes 30-60 minutes and involves inserting 4-12 absorbable PDO or PLLA threads through 18-gauge needle entry points at the hairline. Each thread features 8-16 barbed cogs that anchor into subcutaneous tissue at 3-5mm depth, mechanically lifting sagging skin while triggering collagen production over the following 8-12 weeks.
How Thread Lift Works

Pre-Procedure Consultation and Planning

The thread lift process begins with a detailed facial assessment. The practitioner evaluates skin laxity grade using the Merz Aesthetics Scale (grades 0-4), identifies areas requiring lift, and maps thread placement vectors directly on the skin with a surgical marker. This mapping stage takes 10-15 minutes and determines the number of threads needed — typically 4-8 threads for mid-face lifting and 6-12 for combined jawline and mid-face treatment. Photography documents the baseline position for post-procedure comparison.

Thread selection depends on treatment goals and tissue quality. PDO (polydioxanone) threads dissolve in 6-8 months and suit patients with mild sagging. PLLA (poly-L-lactic acid) threads persist for 12-18 months and provide stronger collagen stimulation for moderate laxity. Barbed cog threads feature directional hooks spaced at 5mm intervals that grip tissue mechanically, while smooth mono threads create collagen scaffolding without direct lifting force.

Step-by-Step Thread Lift Procedure

Anesthesia and Preparation

Local anesthetic — typically 1-2% lidocaine with epinephrine — is injected at each planned entry point and along the thread pathway. This numbs the treatment area within 5-10 minutes. Some practitioners apply topical numbing cream 30 minutes prior for additional comfort. The treatment area is cleansed with chlorhexidine antiseptic solution, and sterile draping isolates the zones receiving threads.

Thread Insertion Process

Using an 18-gauge cannula or needle, the practitioner creates a small entry point at a predetermined location — commonly at the temporal hairline or preauricular area. The cannula guides each thread along the mapped vector beneath the skin at 3-5mm depth, targeting the subcutaneous fat layer just above the SMAS. Once positioned, the practitioner applies gentle traction to engage the barbed cogs with surrounding tissue. The cannula is withdrawn, leaving the thread anchored in place. Each thread insertion takes 2-4 minutes.

What Happens During Thread Activation

After all threads are placed, the practitioner performs manual molding — gentle external pressure applied to ensure even tissue distribution along the thread pathway. This step takes 3-5 minutes and fine-tunes the lift direction and symmetry. Patients observe immediate lifting as the cog barbs physically reposition tissue. The practitioner checks symmetry from multiple angles and may adjust thread tension before trimming excess material at the entry point.

The biological response begins within hours. Thread placement triggers a controlled foreign-body reaction: macrophages and fibroblasts migrate to the thread surface, initiating collagen type I and type III deposition. This fibrotic encapsulation process strengthens the lift over 8-12 weeks, eventually creating a permanent collagen scaffold that maintains structural support even after the thread material dissolves. Suh DH et al. documented measurable collagen density increases around PDO threads at 12 weeks. Suh DH et al. J Cosmet Laser Ther. 2015;17(6):305-309. doi:10.3109/14764172.2015.1039656

Comfort Measures and Patient Experience

Pain during thread lift averages 2-3 on a 10-point scale with proper local anesthesia. Patients report a tugging or pulling sensation during thread placement rather than sharp pain. Entry point creation produces brief pressure lasting 1-2 seconds per site. Vibration anesthesia devices applied near insertion points activate A-beta nerve fibers that override pain signals, further reducing discomfort. The entire procedure from first anesthetic injection to final thread placement takes 30-60 minutes depending on thread count.

RE:BERRY Gangnam uses real-time assessment during placement to optimize each thread vector for the patient's facial anatomy. After completion, cold compresses are applied for 10 minutes, and patients receive written aftercare instructions. No bandaging or dressing is required — entry points measure approximately 1.2mm and seal within hours. Patients walk out of the clinic immediately and can resume light activities the same day.

Frequently Asked Questions

What happens during a Thread Lift session?
A thread lift session involves 4 distinct phases completed in 30-60 minutes total: facial mapping with surgical markers, local anesthetic injection at 2-4 entry points, guided thread insertion at 3-5mm depth using 18-gauge cannulas, and manual molding to optimize symmetry. Patients remain awake throughout, experiencing mild tugging sensations rather than pain.
How long does the procedure take?
The complete procedure takes 30-60 minutes depending on thread count. A mid-face lift using 4-6 threads requires approximately 30-40 minutes, while combined jawline and mid-face treatment with 8-12 threads extends to 45-60 minutes. Pre-procedure consultation and marking add 10-15 minutes, and post-procedure cold compress application adds another 10 minutes.
Does Thread Lift hurt?
Pain averages 2-3 on a 10-point scale when local anesthesia is properly administered. Lidocaine with epinephrine numbs each entry point and thread pathway within 5-10 minutes of injection. Patients describe a pulling or tugging sensation during thread placement rather than sharp pain. Vibration anesthesia devices further reduce discomfort by activating competing nerve signals.
How many sessions do I need?
Most patients achieve satisfactory results from 1 session using 6-12 threads. Approximately 80% of patients require only a single treatment for mild to moderate sagging. Severe laxity may benefit from a second session 3-6 months after the first once collagen remodeling stabilizes. Maintenance sessions every 12-18 months sustain long-term lifting results.
What technology is used?
Thread lifts use absorbable PDO or PLLA suture material with barbed cog designs featuring 8-16 directional hooks per thread. PDO dissolves in 6-8 months, while PLLA persists for 12-18 months. Threads are inserted via 18-gauge cannulas at controlled depths of 3-5mm. Some clinics incorporate ultrasound-guided placement for precision in complex anatomical zones.
What types of threads are used in the procedure?
3 primary thread types serve different purposes in modern thread lifting. Barbed cog threads with directional hooks provide mechanical lift for sagging jowls and mid-face. Smooth mono threads stimulate collagen in fine-line areas. Screw threads create volumizing effects. PDO dissolves in 6-8 months; PLLA lasts 12-18 months with stronger collagen stimulation.
Is Thread Lift suitable for all face shapes?
Thread lift adapts to all face shapes through customized vector mapping, with placement angles varying by 15-30 degrees between oval, round, and square facial structures. Oval faces typically need 4-6 threads focused on mid-face lift. Round faces benefit from 6-8 threads targeting jawline definition. Square faces use lateral vectors to soften angular contours while maintaining structural definition.
