While the concept of inserting barbed sutures dates back to 1956, the clinical application of threads for facial rejuvenation was first published in the late 1990s. In 1998, Dr. Marlen Sulamanidze, a Georgian plastic surgeon, developed non-absorbable barbed threads branded as Aptos (short for anti-ptosis). However, early limitations—such as short-term efficacy and a higher rate of complications (including thread migration, extrusion, infection, and skin dimpling)—led to a temporary decline in popularity.
The surge in demand for minimally invasive aesthetic procedures sparked significant technological refinements. Modern threads vary in chemical composition (affecting degradation rates), structural design (smooth vs. barbed), anchoring mechanisms (barbs vs. 360-degree cones), barb directionality (unidirectional vs. bidirectional), and insertion systems. Beyond these technical parameters, thread procedures are primarily categorized by their intended primary mechanism of action:
Designed primarily to stimulate native collagen production rather than provide mechanical elevation.
Mechanism & Composition: Meso-threads are made of Poly-L-Dioxanone (PDO/PDS) and come in smooth, screw, or micro-barbed configurations delivered via fine needles.
Tissue Response: Over approximately 6 months, the threads naturally degrade. The primary benefit—improved skin texture and mild firming—stems from mechanical micro-trauma combined with an accelerated healing response, marked by neocollagenesis around the thread material. This collagen stimulation softens fine lines and reduces pore size.
Procedure & Recovery: Performed under local anesthesia with minimal downtime, similar to dermal filler injections. Transient side effects may include mild swelling, edema, or minor bruising, resolving within hours to days.
Ideal Candidates: Younger patients without severe skin laxity or heavy tissue ptosis who seek skin firming and preventative maintenance. Meso-threads are frequently combined with dermal fillers for synergistic results, with periodic maintenance recommended every 6 to 12 months.
Designed to mechanically grip subcutaneous tissue to provide a subtle, temporary mechanical lift alongside collagen stimulation.
Aptos Excellence / Light Lift: The modern iteration utilizes absorbable materials composed of Poly-L-Lactic Acid (PLLA) and Polycaprolactone (PCL). Delivered via specialized needles, these threads feature bidirectional barbs. Following manual tissue elevation and vectoring, the thread ends are trimmed. The upward gathering of subcutaneous tissue along the thread axis creates a noticeable vertical lift. Aptos offers both “free-floating” configurations and anchored vectors tailored to specific anatomical zones, including specialized protocols for neck and double-chin contouring.
Happy Lift: Similar in composition (absorbable PCL with PLLA) and function, featuring bidirectional micro-barbs in both free and anchored formats.
Silhouette Soft®: A key advancement in suspension threads, replacing traditional barbs with 360-degree molded cones and delicate knots. The bidirectional cone geometry provides superior 360-degree tissue anchoring without weakening the thread’s core structural integrity.
Composition & Safety: Manufactured from Poly-L-Lactic Acid (PLLA), Silhouette Soft® threads are FDA-cleared and CE-marked.
Application: Inserted under sterile conditions following local anesthesia through small entry points. Micro-cones anchor into the subcutaneous layer, allowing the physician to reshape and elevate specific areas—such as lifting the brows, sharpening the jawline, volume-restructuring the cheeks, and enhancing the cervicomental (face-to-neck) angle.
Longevity: The bidirectional cones are gradually absorbed over 8 to 10 months, while the main thread hydrolyzes fully within 18 to 24 months. The clinical lifting effect typically lasts between 6 to 12 months on average, depending on skin viscoelasticity, tissue thickness, and lifestyle factors.
The choice of thread system depends heavily on skin thickness, tissue density, and the degree of ptosis:
Thicker skin with mild-to-moderate ptosis: Benefitted most by the robust tissue engagement of Aptos threads.
Thinner skin with mild laxity: Best suited for Silhouette Soft® due to its smooth cone profile and soft integration.
To maximize clinical longevity, thread lifting is frequently combined with dermal fillers, skin resurfacing, and energy-based devices (CO2 laser, RF). Maintenance treatments may be scheduled every 3 to 6 months based on individual patient goals.
Summary of Indications: Thread lifting offers a swift, effective option for younger patients with early structural laxity and realistic expectations. It serves as an excellent preventative strategy, a complementary procedure alongside a surgical facelift, or an ideal solution for patients unable or unwilling to undergo surgery. However, for cases with significant skin excess and severe structural sagging, surgical intervention remains the definitive gold standard for complete facial restoration.
