The PLLA screw threads, also known as PLLA twist threads, are a type of absorbable biostimulatory lifting thread. They are formed by winding a single PLLA thread into a screw-shaped structure, thereby enhancing the tissue-anchoring ability and volumizing effect.
Compared with mono threads, screw threads have a stronger space-filling capacity. They are more suitable for correcting localized depressions. Yastrid PLLA twist threads provide stronger collagen stimulation. As PLLA gradually hydrolyzes, it can continuously stimulate fibroblast activity, promoting type I collagen regeneration, type III collagen remodeling, and skin tightening and firming.
Yastrid, as a professional PLLA screw threads supplier, offers online services to various types of customers and provides door-to-door delivery support.

In the field of medical aesthetic threads, Yastrid PLLA screw threads have much higher requirements for doctors' operational experience, material stability, and clinical safety than ordinary PDO threads. Yastrid has systematically optimized its product design around handling performance, material science, compliance, and clinical support to meet the high standards of professional medical institutions.
In clinical procedures, the sharpness of the needle directly affects the penetration force and the comfort of the patient.
Yastrid PLLA screw threads are made of the following:
For sharp needle screw threads, their advantages lie in reducing tissue trauma, lowering pain perception, and enhancing procedural efficiency.
The core value of PLLA screw threads lies in its helical structure.
Yastrid focuses on control during the manufacturing process:
✅Tight spiral winding consistency
✅Anti-loosening thread fixation
✅Shape retention during insertion
Ergonomic needle hub design
Color-coded hub system
Stable thread deployment mechanism
Make sure:
Tensile Strength vs Brittleness
Compared with PDO threads, the PLLA material has a stronger biostimulatory capacity, but at the same time, it has a higher brittleness sensitivity.
Optimization of Yastrid PLLA Screw Threads:
Effectively reduce:
Sterilization Technology
Yastrid PLLA threads use the industry-standard sterilization protocol: EO sterilization/gamma irradiation.
Key Control:
Packaging System
For the design of PLLA moisture sensitivity:
Make sure:
As collagen loss, volume deficiency, and skin laxity continue to worsen, aging signs such as jawline sagging, deepening nasolabial folds, and prominent neck lines will gradually appear on the face and neck. The Yastrid PLLA screw threads, through their screw-shaped volumizing structure and long-lasting collagen stimulation, can help enhance facial support, improve skin firmness, and gradually restore youthful facial contours.
Compared to traditional short-term filling treatments, PLLA biostimulatory threads place greater emphasis on natural-looking rejuvenation and progressive collagen remodeling. By continuously promoting the regeneration of Type I and Type III collagen, it can effectively improve facial volume loss, skin looseness, and wrinkle formation, allowing the skin to regain a firmer, smoother, and more youthful appearance.
Whether it is used for jawline tightening, nasolabial fold reduction, or neck rejuvenation, Yastrid PLLA screw threads have become one of the important solutions in modern anti-aging treatments and non-surgical facelift procedures.
Why are more and more doctors starting to prefer PLLA screw threads over PDO screw threads?
Compared with traditional PDO threads, PLLA screw threads have a stronger biostimulatory effect and a longer collagen regeneration cycle.
Yastrid PLLA screw threads not only provide immediate volumizing support but also can continuously stimulate the synthesis of type I and type III collagen.
For doctors seeking natural and long-term anti-aging solutions, PLLA is currently a key trend material in high-end facial rejuvenation treatments.
Will PLLA threads be more prone to breakage compared to PDO?
This is one of the issues that many doctors pay the most attention to when purchasing PLLA lifting threads.
Since the hardness of PLLA material is higher than that of PDO, if the manufacturing process is unstable, it is indeed possible to increase the risk of brittleness.
Yastrid PLLA Screw Threads Through:
To enhance the flexibility of the wire and improve its resistance to fracture.
During the process of online body pushing, movement organization, and patient expression activities, it is possible to maintain stable structural integrity and reduce the risk of intraoperative damage.
Is the helical structure of Yastrid PLLA twist threads prone to loosening and straightening?
No. The core value of screw threads lies in their volumizing spiral structure. If the winding stability of the threads is insufficient, they may become loose prematurely when entering the subcutaneous tissue, thereby losing their volume-enhancing effect.
Are the nodules associated with Yastrid PLLA threads more likely to occur?
The risk of nodules is usually closely related to factors such as implantation depth, product purity, and injection technique.
Yastrid PLLA screw threads are made of the following:
Help reduce the risk of granuloma formation, delayed-onset nodules, and excessive foreign-body reactions.
At the same time, we recommend that the PLLA threads be implanted in the correct subcutaneous layer or superficial SMAS plane to avoid overly shallow implantation, which may lead to palpable thread visibility or the risk of local nodules.
Does Yastrid offer different specifications of PLLA twist threads?
Yes.
For different anatomical treatment areas, Yastrid offers a complete specification system, including:
30G 25mm → Under-eye hollows / fine lines
29G 38mm → Mid-face rejuvenation
27G 50mm / 60mm → Cheek & jawline support
At the same time, support is provided for:
PLLA Mono Screw Threads
PLLA Double Screw Threads
PLLA Tornado Threads
Satisfy different
Volume deficiency severity
Skin thickness
Lifting intensity requirements
Help doctors establish more comprehensive, personalized thread lifting protocols.
What sterilization method is used for Yastrid PLLA twist threads? Is the residual EO safe?
Yastrid PLLA Twist Threads are produced using the professional EO sterilization process.
Because the PLLA material is sensitive to high temperatures, EO sterilization can provide better protection:
Polymer stability
Thread flexibility
Structural consistency
At the same time, we strictly control:
EO residue levels
Aeration period
Sterility assurance standards
Ensure that the product complies with medical device safety requirements and reduce the following:
How long can PLA twist threads generally last?
Compared to PDO threads, PLLA twist threads usually have a longer clinical longevity.
In general:
