Thread Lifting in Korea: Complete Guide (PDO/COG) Prices & Results 2025

When sagging skin, jowls, and loss of facial definition start affecting your appearance, but you're not ready for surgical facelift, thread lifting offers a compelling middle ground. This minimally invasive procedure uses dissolvable PDO (polydioxanone) or COG threads to lift and rejuvenate facial tissues, delivering immediate visible results with minimal downtime.

Korea has become a global leader in thread lift technology, with advanced thread types, refined techniques, and experienced practitioners making Seoul a top destination for this procedure. In this comprehensive guide, we'll explore everything you need to know about thread lifting in Korea, from understanding different thread types to pricing, expected results, and choosing the right clinic.

What is Thread Lifting?

Thread lifting (실리프팅) is a minimally invasive cosmetic procedure that uses medical-grade dissolvable threads inserted under the skin to physically lift sagging tissue and stimulate collagen production. Unlike surgical facelifts that require incisions, anesthesia, and extended recovery, thread lifts can be performed in under an hour with local anesthesia and minimal downtime.

How Thread Lifting Works

Dual Mechanism of Action:

1. Immediate Mechanical Lift:

   • Threads with barbs or cogs physically grab tissue
   • Pull sagging skin upward and backward
   • Anchor to stable facial structures
   • Instant visible lifting effect

2. Long-Term Collagen Stimulation:

   • PDO material triggers foreign body response
   • Fibroblasts produce new collagen around threads
   • Tissue thickening and firming over 3-6 months
   • Continued improvement even as threads dissolve

Thread Material: PDO (Polydioxanone)

Why PDO is Safe:

• Biocompatible: Used in surgery for decades (sutures)
• FDA-approved: Recognized as safe for medical use
• Absorbable: Naturally dissolves via hydrolysis
• No residue: Breaks down into water and CO₂
• Non-allergenic: No allergic reactions reported

Absorption Timeline:

• Begins dissolving: 3-4 months
• Fully absorbed: 6-12 months
• Collagen persists: 12-24 months

   • Shows before/after photos of similar cases

2. Treatment Planning:

   • Customized thread plan
   • Discussion of realistic expectations
   • Review of medical history
   • Cost breakdown

3. Pre-Treatment Instructions:

   • Avoid blood thinners (aspirin, ibuprofen) for 7 days
   • Stop smoking 2 weeks before (impairs healing)
   • Avoid alcohol 48 hours before
   • Come with clean face, no makeup

Typical Thread Requirements by Area:

Thread lifting is a medical procedure that should only be performed by qualified, licensed plastic surgeons or dermatologists with specific training in thread techniques. Individual results vary significantly based on degree of sagging, skin quality, age, number and type of threads used, practitioner skill, and adherence to aftercare protocols. While generally safe when performed correctly, all procedures carry risks including infection, asymmetry, nerve damage, thread migration, extrusion, and unsatisfactory results. Complications can be serious and may require thread removal or corrective procedures. Always consult with a board-certified plastic surgeon before undergoing thread lift.
