Nasolabial folds deepening and jawline blurring – the tired look that comes with facial sagging is genuinely worrying. This article clarifies how to choose between thread lift options, and whether a Large V or Small V thread is better for you. The Large V thread provides deep anchoring and lifting, specifically improving moderate to severe sagging; the Small V thread evenly tightens the superficial dermis, suitable for mild to moderate laxity and rough skin texture. As for recovery and duration, after reading this, you will have a clearer direction for your choice and can communicate with your doctor with more confidence.
Both Large V and Small V threads are KFDA‑certified thread lift technologies, with the core mechanism being the synergy of physical lifting and biological stimulation. The Large V thread uses thick, barbed PDO or PCL threads anchored in the SMAS layer, providing a mechanical lift that directly repositions sagging buccal fat pads, immediately improving moderate to severe nasolabial folds. The Small V thread uses fine spiral or smooth short PDO threads evenly distributed in the deep dermis, continuously activating fibroblasts to promote new collagen and elastin production. In Gangnam clinics, these are often used in layered combination to address both mid‑face sagging and jawline blurring.
Large V thread: Particularly suitable for patients over 40 with obvious cheek sagging, deep nasolabial folds, and a disappearing jawline, or those with excess facial fat and skin redundancy after weight loss. Contraindications include coagulation disorders, facial infections, or undiagnosed severe ptosis.
Small V thread: For mild to moderate nasolabial folds, marionette lines, and rough skin texture in the early ageing population (from age 30). Also suitable as a prejuvenation measure to tighten the jawline and prevent sagging. Contraindicated during pregnancy, protein thread allergy, or unstable fillers. If you have both deep wrinkles and mild laxity, a combined approach is often superior to a single option.
In Korea, doctors choose the thread type based on the depth of your nasolabial folds and the flaccidity of your jawline. The table below provides a clear comparison (prices in KRW):
| Comparison Dimension | Large V Thread | Small V Thread |
|---|---|---|
| Thread Diameter | 0.8 – 1.2 mm (thick barbed) | 0.3 – 0.5 mm (spiral/smooth) |
| Implantation Layer | SMAS layer & deep fat pad | Deep dermis & superficial fascia |
| Main Improvement | Moderate to severe nasolabial folds, jawline lift | Fine lines, skin texture refinement |
| Duration | 12 – 18 months | 6 – 12 months |
| Single‑session Price Range (KRW) | ₩2,500,000 – 4,000,000 | ₩1,200,000 – 2,000,000 |
For nasolabial folds + jawline blurring, Gangnam doctors often recommend a “deep Large V anchoring + superficial Small V tightening” combo therapy. The combined price is approximately ₩3,500,000 – 5,500,000 KRW, offering better overall value than a single procedure.
Step 1 – Consultation and design: The Korean doctor uses palpation and Vectra 3D imaging to analyse the nasolabial fold depression volume and the soft tissue sagging vector of the jawline, marking entry points. You can discuss your expectations in detail; this stage takes about 15 minutes.
Step 2 – Anaesthesia and precise implantation: Topical anaesthetic cream combined with local infiltration anaesthesia significantly improves pain tolerance. The Large V thread uses a thicker cannula for deep SMAS anchoring (about 50 minutes), while the Small V thread uses a fine needle for subcutaneous mesh‑like placement (about 30 minutes). You may feel a distinct tugging sensation and pressure, but no sharp pain.
Step 3 – Moulding and immediate observation: After the procedure, the doctor gently presses to smooth the tissue around the threads, and checks facial symmetry while you are seated. Only tiny needle holes remain. Nasolabial folds appear shallower and the jawline tighter immediately, but swelling typically develops over the following hours, which is a normal physiological response.
Immediate Effect: After the Large V thread, the mid‑face lift is pronounced, nasolabial folds are significantly reduced, and the jaw angle contour becomes clearer; the Small V thread brings an overall tightening and improved skin radiance. Progressive Effect: New collagen begins to form around the threads at 2‑4 weeks post‑op, peaking at 3‑6 months, with continued improvement in skin elasticity and fine lines. The Large V thread lasts 12‑18 months, while the Small V thread lasts 6‑12 months. Regular maintenance with HIFU or RF can extend the overall effect by 3‑6 months.
Q1: For deep nasolabial folds, should I choose Large V or Small V?
If the folds are caused by severe mid‑face sagging, the Large V thread is the primary choice for deep repositioning; if the lines are shallow and accompanied by fine lines, the Small V thread may suffice. In most cases, combined treatment yields the best results, with Seoul prices around ₩3,500,000 – 5,500,000 KRW.
Q2: How defined will my jawline become?
The Large V thread provides a very clear jawline lift, with the submental angle visibly reduced immediately, creating a “V‑shape” contour. However, the outcome depends on your neck fat and muscle conditions; ask the doctor to perform a Pinch Test during consultation.
Q3: What is the downtime? Will it affect work?
Mild swelling on day 1, subsiding by day 3; needle holes disappear completely in about 1 week. Apply ice packs for the first 3 days, avoid exaggerated facial expressions and facial massage for 2 weeks. It generally does not affect daily social activities and is office‑friendly.
Q4: Which clinics in Korea are good for thread lifts?
Gangnam, Seoul, has many Board‑Certified doctors. It is recommended to choose a clinic that uses KFDA‑certified threads (e.g., Mint, Ultra V) and has extensive revision experience, and to verify the doctor’s credentials before the procedure.
Common Side Effects of thread lifts include redness, mild bruising, and foreign‑body pulling sensation within 3 days post‑op. In rare cases, thread exposure, local depressions, or temporary asymmetry may occur. Be sure to choose a licensed Korean dermatology clinic and an Experienced Physician, and carefully read all terms in the Informed Consent before signing. View promotional images realistically – actual results vary individually. The prices in this article are based on 2026 Gangnam market averages; actual costs depend on thread brands and quantity used – please confirm with the clinic’s official quote. Be sure to discuss your true expectations thoroughly with the doctor before surgery.
