How Thread Lift Works
Thread lift is a minimally invasive facial rejuvenation procedure that uses absorbable sutures to physically reposition sagging skin. A practitioner inserts thin, barbed threads beneath the skin using a cannula or needle, anchoring them in the subcutaneous tissue at depths of 3-5mm. The barbs or cogs along the thread grip surrounding tissue, creating an immediate mechanical lift that redefines the jawline, cheeks, and midface.
Beyond the instant repositioning effect, threads trigger a foreign-body healing response. As the body metabolizes the thread material over 6-8 months, fibroblasts deposit new collagen along the thread pathway. This neocollagenesis reinforces the initial lift with structural protein that persists after the threads dissolve. The dual mechanism of immediate lift plus delayed collagen stimulation distinguishes thread lifting from energy-based devices that rely on collagen alone.
Types of Threads Used in Korea
PDO Threads
Polydioxanone (PDO) threads are the most widely used type in Korean aesthetic clinics. PDO is a synthetic absorbable polymer with a proven safety record spanning 30 years in cardiovascular and orthopedic surgery. The threads dissolve completely within 6-8 months. PDO threads come in three configurations: mono (smooth) for skin rejuvenation, cog (barbed) for tissue lifting, and screw (twisted) for volume restoration. A standard jawline lifting protocol uses 4-8 cog threads per side.
PLLA Threads
Poly-L-lactic acid (PLLA) threads offer extended collagen stimulation lasting 12-18 months before full absorption. PLLA is the same biocompatible material used in Sculptra dermal filler. These threads produce stronger long-term collagen induction compared to PDO, making them suitable for patients with moderate laxity who want prolonged results. PLLA cog threads are commonly selected for cheek and midface lifting procedures.
Who Benefits from Thread Lift
Thread lift is best suited for adults aged 30-55 with mild to moderate facial sagging. Ideal candidates present with early jowling, loss of jawline definition, midface descent, or sagging cheeks but have sufficient skin thickness to anchor the threads. A study published in the Journal of Cosmetic Dermatology found that 91% of patients aged 35-50 rated their thread lift results as satisfactory at 12 months. Sulamanidze MA et al. J Cosmet Dermatol. 2019;18(5):1277-1283. doi:10.1111/jocd.12870
Contraindications include active skin infections, autoimmune connective tissue disorders, bleeding disorders, and pregnancy. Patients with severe sagging classified as Merz scale grade 3-4 generally require surgical intervention rather than thread lifting. An aesthetic medicine specialist evaluates tissue quality, fat volume, and skin elasticity during consultation to determine whether threads alone or a combination approach produces the best outcome.
The Thread Lift Procedure Step by Step
The procedure takes 30-60 minutes depending on the number of threads and treatment areas. After applying topical anesthesia for 20-30 minutes, the practitioner marks insertion and exit points on the skin. Local anesthetic is injected at entry points. Using a blunt cannula, the practitioner feeds each thread along the predetermined path beneath the skin. Once positioned, the thread is anchored and the cannula withdrawn, leaving the barbed thread to grip and lift tissue. Entry points require no sutures.
Thread lifting in Gangnam starts at ₩200,000 ($154 USD) per line, with a typical full treatment involving 8-16 threads depending on the degree of correction required. RE:BERRY Gangnam Aesthetic Medicine Specialist Yoon-Gon Ryu assesses each patient's tissue laxity to determine the optimal thread count and placement pattern for natural-looking results.
Recovery and Expected Results
Recovery from thread lift is minimal compared to surgical alternatives. Mild swelling and bruising peak at 24-48 hours and resolve within 5-7 days. Patients return to normal activities within 1-2 days, avoiding strenuous exercise and facial massages for 2-3 weeks. Sleeping face-up for the first 7 nights prevents thread displacement.
The immediate lifting effect is visible from day one. Collagen remodeling continues for 3-6 months, producing progressive skin quality improvement alongside the mechanical lift. Final results stabilize at approximately 3 months and last 12-18 months. A maintenance session at the 12-month mark extends results by reinforcing the collagen matrix before significant degradation occurs. Thread lifting can be combined with Botox and dermal fillers for comprehensive facial rejuvenation.
