NeoGenesis® PDO Mono M2938 (29G x 38mm) – 20 Threads
NEOGENESIS® PDO Mono M2938 is a premium medical-grade Polydioxanone (PDO) mono thread designed to support skin rejuvenation, collagen stimulation, tissue strengthening and overall skin-quality improvement.
Manufactured by NeoGenesis Co., Ltd. in South Korea, the M2938 combines a 29G × 38mm guide needle with a 50mm smooth PDO filament in USP 6-0, providing practitioners with a fine mono thread suitable for professional collagen-induction and skin-rejuvenation protocols.
Unlike cog or screw threads that may be selected for mechanical lifting or additional tissue support, mono threads are smooth, non-barbed filaments that work primarily through the tissue response generated following implantation.
Once placed within the appropriate tissue plane, the PDO filament acts as a temporary scaffold and initiates a controlled healing response associated with fibroblast activity, collagen formation and progressive tissue remodelling.
As the Polydioxanone gradually undergoes hydrolysis and is absorbed by the body, the surrounding tissue response may continue to support improvements in skin firmness, elasticity, texture and overall dermal quality.
This makes NEOGENESIS® PDO Mono M2938 particularly suited to patients seeking progressive skin-quality improvement and collagen stimulation rather than significant mechanical lifting or volumisation.

Product Composition
Medical-Grade Polydioxanone (PDO)
The M2938 contains a smooth filament manufactured from medical-grade Polydioxanone, a fully absorbable synthetic polymer with an established history of use within absorbable surgical sutures.
Following implantation, PDO gradually undergoes hydrolysis within the tissues before being naturally absorbed.
During this period, the presence of the thread creates a local tissue response associated with fibroblast activity, collagen formation and tissue remodelling.
Medical-Grade Stainless Steel Guide Needle
Each PDO filament is supplied with a precision-manufactured stainless steel guide needle designed to facilitate controlled placement by an appropriately trained practitioner.
The M2938 configuration comprises:
• 29G needle
• 38mm needle length
• 50mm PDO filament
• USP 6-0 thread
The product is sterile, biocompatible, biodegradable, latex-free and intended for single use only.
Mono Thread Technology
NEOGENESIS® PDO Mono M2938 is a smooth, single-filament PDO thread designed primarily for collagen induction and skin-quality improvement rather than mechanical lifting.
Unlike barbed cog threads, the smooth mono filament does not rely upon barbs to engage and reposition tissue.
Instead, once appropriately implanted, the thread provides a temporary scaffold around which a controlled regenerative response can occur.
Over time, this process is designed to support progressive improvements in the quality and characteristics of the surrounding tissues.
The smooth mono design allows appropriately trained practitioners to create treatment patterns designed to:
• Support collagen stimulation
• Improve dermal density
• Strengthen thin or ageing skin
• Improve skin texture
• Support areas of mild skin laxity
• Improve overall skin quality
• Complement combination rejuvenation protocols
Mono threads may be placed in multiple parallel, linear or cross-hatched patterns according to the treatment area, patient anatomy, professional training and manufacturer's current guidance.
PDO Collagen Stimulation
The implantation of PDO threads produces a controlled local tissue response that can stimulate natural regenerative processes.
The surrounding tissue response is associated with:
• Fibroblast activity
• Collagen production
• Elastin-related tissue remodelling
• Formation and reorganisation of connective tissue
• Progressive dermal remodelling
• Improved tissue quality
Rather than creating the immediate mechanical repositioning associated with lifting threads, the effects of mono PDO threads develop progressively as the surrounding tissues respond.
As the PDO filament is gradually absorbed, the collagen-rich tissue response generated around the treatment area may continue to support improved firmness, elasticity and skin quality.

Common Treatment Areas
Following appropriate consultation, professional assessment and confirmation within the manufacturer's current Instructions for Use, NEOGENESIS® PDO Mono M2938 may be incorporated into professional treatment protocols involving areas such as:
• Forehead
• Crow's feet
• Periorbital region
• Cheeks
• Mid-face
• Nasolabial region
• Marionette region
• Jawline
• Chin
• Neck
• Décolletage
• Back of the hands
• Upper arms
• Abdomen
• Knees
• Selected areas of textural irregularity
• Areas of mild skin laxity
• Other authorised facial or body areas requiring collagen stimulation
Treatment suitability should always be determined according to the patient's anatomy, skin quality, tissue thickness, degree of laxity, medical history and individual treatment objectives.
Mono PDO threads are particularly suited to improving skin quality and stimulating a progressive tissue response rather than producing significant mechanical lifting.
Professional Treatment Considerations
The number of NEOGENESIS® PDO Mono M2938 threads required will vary according to factors including:
• Treatment area
• Degree of skin laxity
• Desired level of collagen stimulation
• Skin and tissue thickness
• Individual anatomy
• Existing skin quality
• Previous aesthetic treatments
• Practitioner assessment
Treatment planning should include:
• Comprehensive medical consultation
• Assessment of facial or body anatomy
• Review of previous aesthetic procedures
• Evaluation of skin and tissue quality
• Assessment of contraindications
• Discussion of realistic treatment expectations
• Explanation of potential side effects and complications
• Appropriate documented informed consent
Thread placement, insertion depth, treatment pattern and total number of threads should always follow the manufacturer's current Instructions for Use together with appropriate product-specific training and professional clinical judgement.
Where clinically appropriate, mono threads may form part of a broader professional skin-rejuvenation programme alongside other treatments. The timing and suitability of combination treatments should be individually assessed.
Results & Longevity
Results from PDO mono thread treatment are generally progressive rather than based upon immediate mechanical lifting.
Patients may notice subtle changes in skin quality during the early post-treatment period, with further improvements potentially developing as the surrounding tissues undergo collagen-related remodelling.
Potential improvements may include:
• Improved skin firmness
• Enhanced elasticity
• Improved skin texture
• Increased dermal density
• Smoother-looking skin
• Reduced appearance of fine lines
• Improved overall skin quality
• Healthier and more rejuvenated-looking skin
• Improvement in areas of mild skin laxity
According to the supplied product information, PDO threads gradually absorb over approximately 6–8 months, while tissue remodelling may continue beyond the period of thread absorption.
Individual results and longevity will vary according to factors including:
• Patient age
• Baseline skin and tissue quality
• Treatment area
• Number and placement of threads
• Metabolism
• Lifestyle
• Practitioner technique
• Individual biological response
Maintenance or additional treatment may be considered following appropriate professional reassessment.
