FAQ About Yastrid PLLA Mono Threads
What are the main differences between PLLA smooth threads and PDO smooth threads?
PDO smooth threads mainly stimulate collagen production during the approximately 6-month degradation process, while PLLA smooth threads are a stronger biostimulator. PLLA continuously degrades within 18-24 months and can stimulate neocollagenesis for a long time, forming a more stable and denser collagen matrix. Therefore, in terms of skin tightening and long-term anti-aging, PLLA usually has better effects than PDO.
How can the risk of nodules or granulomas be reduced when using PLLA smooth threads?
Yastrid PLLA smooth threads are made from high-purity medical-grade PLLA raw materials and strictly control the polymer uniformity and degradation kinetics. The uniform and stable degradation process helps to reduce particle aggregation, thereby lowering the risk of late-onset nodules and granulomas and improving clinical safety.
Which needle gauges and lengths are suitable for PLLA mono threads?
For the under-eye area and tear troughs, the following specifications are typically recommended:
29G / 30G
25mm / 38mm
For neck tightening and addressing neck lines, the following are commonly used:
26G / 27G
38mm / 50mm / 60mm
Different specifications are suited to varying tissue depths and the specific requirements of the "Mesh Technique."
Are PLLA smooth threads suitable for the mesh/grid technique?
Yes, Yastrid PLLA Smooth Threads possess excellent flexibility and tensile strength, making them suitable for the mesh/grid technique.
For the Full Neck Tightening treatment, the following are usually required:
- 30–50 pcs PLLA Smooth Threads
- Adjust according to skin laxity and the treatment area.
The cross-grid implantation helps to form a collagen support network, enhancing the tightening effect.
How to enhance physician procedural fluency and patient comfort?
Yastrid PLLA smooth threads feature the following:
- Ultra-thin Wall Needle Design
- Triple-bevel Needle Technology
- Medical-grade Silicone Coating
These features effectively reduce insertion resistance, minimize tissue trauma, bruising, and swelling, help lower the patient's pain score, and enhance procedural stability for the practitioner.
