PLLA (Poly-L-lactic acid) is a biocompatible, biodegradable polymer widely used in medical aesthetics because it stimulates collagen production as it gradually dissolves in the body. When used for threads, PLA provides both immediate mechanical lifting and long-term skin rejuvenation by promoting neocollagenesis, making it an excellent material for thread lifting as it combines safety, durability, and natural-looking results.





Steigen Carving is the latest design as an unheated molding cog showing remarkable tensile strength and less irritation under the skin. The arrowhead like shape(2D) of the cog is excellent in fixation and tightening of the skin which allows more dramatic contouring results. As a bi-directional original type, application is for the overall facial line from temple to mid-face and mandible to ear.

Steigen Original is bi-directional barbed PDO, PCL and PLA thread for overall facial contouring. The 360'(6D) spiral slice cog design maximizes the fixation capacity and stability of the result. As an absorbable barbed thread, Steigen Original has been widely used for the longest and proven its reliability.

Steigen Little is the most widely used model which can be applied to almost every design on facial parts such as jawline, double chin, neck wrinkle, nasolabial folds, and crow feet. Various applications are available with Steigen Little for itself and it's also good to be used as a supplement combining with other size threads to maximize the duration time of result.

Steigen KONKO is for nose shape contouring by inserted into the nasal columella, dorsum bridge, and glabella. The cannula of KONKO has an optimal tip angle to prevent excessive insertion to nasal bone or ANS (anterior nasal spine). As nasal skin is firm and has lots of movement, KONKO thread has a reliable thickness (USP) in particular, half folded, and uni-directional cog to prevent migration in post-treatment.

As the smallest and safest model, Steigen Eye is for fine wrinkle improvement around the orbital rim where requires special attention to blood vessels and nerve damages. Main feature of the Steigen Eye is 30G full cannula for minimizing any tissue damage, bruising or swelling. The thread has bumpy surface called embossing mono to increase the contact area with the skin leading to a better tightening effect.

Steigen Eldorado is a 99.9% pure gold coated PDO thread with unique technology that power of 20,000 gausses in a vacuum. Under the skin, gold activates the basal cell which leads to better elasticity and prevents depletion of collagen level while PDO thread physically supports the sagging skin. Moreover, it stimulates blood circulation, improving skin tone, reducing acne and other inflammatory disorders.

Steigen Twin has a double-helix form which gives extra physical support under the skin. The gap between the threads induces collagenesis effect inside leading to the longer duration time of the result even after degradation of the thread.

Steigen Screw has spring shape design for natural volumizing effects on fine lines and sagging areas. A simple but effective way to improve various facial & body parts where requires more delicate approaches.
See Details
Steigen Mono is the most basic type of thread widely used in skin rejuvenation, wrinkle improvement, and body contouring. With its various usability and application, Steigen Mono is a well- known essential requirement.
