Introduction

In today’s fast-evolving world of aesthetic medicine, thread lifting has become a go-to option for patients who want to restore youthful contours without the downtime or risks of traditional surgery. At Face Plus Plastic Surgery in Seoul’s Gangnam district, we frequently consult with patients—both local and international—seeking effective, non-surgical lifting options. One of the most common questions we hear is: What’s the difference between PDO threads and PLLA threads? And more importantly, which one looks more natural and lasts longer?

If you’re asking this question, you’re not alone. Understanding the differences between these two powerful tools—PDO (Polydioxanone) and PLLA (Poly-L-Lactic Acid)—can help you make the right decision for your aesthetic goals. Let’s walk through it together.

What Are Thread Lifts and Why Are They So Popular?

Thread lifting is a minimally invasive procedure that lifts and tightens sagging skin using dissolvable sutures. Unlike a surgical facelift, thread lifts don’t require general anesthesia or long recovery periods. Think of it as a supportive internal scaffolding that also stimulates collagen production.

At Face Plus Plastic Surgery, we’ve seen a significant rise in interest for thread lifts, especially among patients in their late 30s to early 50s who are looking to rejuvenate their appearance without going under the knife. Korean patients often prefer subtle, natural enhancements that preserve the facial harmony, while international patients appreciate the low downtime and long-term skin improvement.

What Are PDO Threads?

PDO (Polydioxanone) threads have been used in surgical settings for decades, particularly in cardiovascular surgeries, thanks to their safety and reliability. In aesthetics, PDO threads are primarily used for:

• Mild to moderate skin lifting

• Improving skin elasticity

• Stimulating natural collagen over time

PDO threads typically begin dissolving within 6 months and are fully absorbed by the body in about 6–9 months. However, their effects—thanks to collagen stimulation—can last up to 12–18 months in some patients.

Advantages of PDO Threads:

• Great for first-time patients who want a gentle lift

• Lower cost compared to other thread types

• Safe and widely studied material with decades of clinical use

• Offers skin rejuvenation benefits in addition to lifting

At Face Plus, we often recommend PDO threads for younger patients or those primarily looking for skin tightening rather than deep structural lifting.

What Are PLLA Threads?

PLLA (Poly-L-Lactic Acid) threads are made of the same material found in injectable Sculptra®, known for its ability to stimulate collagen over time. PLLA threads are stronger and more durable than PDO threads, making them ideal for:

• Moderate to significant skin laxity

• Midface lifting and jawline sculpting

• Patients seeking longer-lasting results

PLLA threads dissolve more slowly than PDO, typically over 12–18 months, with lifting effects that may last up to 2 years or more, depending on the patient’s skin condition and lifestyle.

Advantages of PLLA Threads:

• Stronger lifting power, especially for deeper facial tissues

• Longer-lasting results compared to PDO

• Superior for mid-to-lower face sagging

• Ongoing collagen regeneration even after threads dissolve

Because of their strength and longevity, PLLA threads are frequently used at our clinic for patients seeking structural lifting with natural, yet noticeable results—especially in areas like the jawline, cheeks, and nasolabial folds.

PDO vs. PLLA: Side-by-Side Comparison

Which One Looks More Natural?

Both PDO and PLLA threads are designed to create natural-looking results—but the key to achieving this isn’t just the thread material. It’s how and where the threads are placed, and by whom.

At Face Plus Plastic Surgery, our approach to thread lifting is based on an in-depth understanding of facial anatomy and aging patterns. Under Dr. Jung Keun Park’s guidance, we create customized thread lift plans for each patient. Whether you choose PDO or PLLA, your results will reflect our clinic’s philosophy: natural enhancement, artistic precision, and personalized care.

That said, PDO threads often give a softer, more subtle lift, ideal for delicate enhancements. PLLA threads, due to their stronger lifting capacity, are better suited for structural support and visible contour changes that still look organic when done correctly.

How We Choose the Right Thread for You

Choosing between PDO and PLLA isn’t a one-size-fits-all decision. During your consultation at Face Plus, we evaluate several factors:

• Your age and skin condition

• The degree of sagging

• Areas you want to treat (cheeks, jawline, neck, etc.)

• Lifestyle factors (smoking, sun exposure, etc.)

• Whether you want a subtle refresh or a more dramatic lift

We may even recommend combining different types of threads or pairing a thread lift with other treatments such as Ultherapy, dermal fillers, or botulinum toxin for a more comprehensive anti-aging strategy.

What to Expect Before and After a Thread Lift

Many patients are pleasantly surprised by how quick and comfortable the thread lift procedure is. Here’s a general outline of what you can expect:

Before the Procedure:

• A detailed consultation with Dr. Park or one of our expert aesthetic practitioners

• Photographic analysis to map out ideal thread placement

• Local anesthesia to minimize discomfort

During the Procedure:

• Threads are gently inserted through a small needle or cannula

• The lift effect is immediate, with continued improvement over 2–3 months

Aftercare:

• Minor swelling or bruising may occur but resolves within days

• Avoid heavy exercise, alcohol, and facial massage for 1–2 weeks

• You can typically return to work the next day

Most patients describe the recovery as minimal and manageable—especially compared to surgery.

Final Thoughts: Which Thread Is Best for You?

When considering a thread lift, it’s not about which thread is objectively better. It’s about what’s right for you.

• If you’re in your 30s to early 40s and want to address early signs of aging with a natural finish, PDO threads might be the best fit.

• If you’re dealing with deeper sagging and want a more robust, longer-lasting lift, PLLA threads may offer the ideal solution.

At Face Plus Plastic Surgery, we take pride in tailoring each treatment to your unique needs. Whether you choose PDO or PLLA, you can trust that your lift will be performed with the utmost care, backed by science, artistry, and 21+ years of expertise from Dr. Park.
