PDO cog mesothreads for facial and body lifting (4D 360\u00b0 COG in cannula)

Description

Velancia COG PDO Thread (Velancia 360° 4D COG, Cannula Cog) is an absorbable polydioxanone (PDO) barbed thread system from Koru Pharma designed for minimally invasive lifting and bio-reinforcement of facial and body tissues. The 4D 360° cog geometry provides multidirectional anchoring within the subdermal tissues, creating an internal support framework that lifts sagging skin and stimulates collagen and elastin production. Threads are preloaded in thin, flexible cannulas (19G or 21G, 100 mm) and are intended for use by trained medical professionals for contouring areas such as nasolabial folds, cheeks, chin, jawline, eyebrows, neck and selected body regions. PDO completely biodegrades over several months, while the newly formed collagen scaffold provides a longer-lasting lifting and tightening effect.

Bnefits

  • Minimally invasive lifting and tightening of facial and body tissues using absorbable PDO cog threads in cannulas.
  • 4D 360° cog design with multidirectional barbs to create a stable internal support framework and strong tissue fixation.
  • Improvement of skin tone and elasticity with stimulation of collagen and elastin through controlled fibrotic response around the threads.
  • Reduction in the depth and visibility of wrinkles, including nasolabial folds and perioral and periorbital lines.
  • Restoration and enhancement of facial contours (cheeks, jawline, chin) without adding extra volume, suitable for patients who do not need additional fullness.
  • Biodegradable polydioxanone material that is fully resorbed, leaving water and carbon dioxide as end products.
  • High biocompatibility and hypoallergenic profile as stated by the manufacturer and distributor (100% tissue compatibility, no reported allergic reactions in product literature).
  • Use of thin, elastic cannulas/needles that separate rather than cut tissues, contributing to minimal trauma and short recovery time.
  • Possibility of combining treatment with other aesthetic procedures such as ultrasound lifting, RF-lifting, laser resurfacing, peels, mesotherapy and hyaluronic acid injections.
  • Long-lasting aesthetic effect: Koru Pharma documentation states a rejuvenating effect of up to about 2 years for Velancia COG threads, with some distributor materials describing prolonged support beyond PDO resorption.

Indications

  • Thread lifting and bio-reinforcement for mild to moderate facial skin laxity.
  • Correction of nasolabial folds and lines.
  • Wrinkles and skin laxity around the mouth (perioral lines, lip–chin lines).
  • Crow’s feet and wrinkles around the eyes.
  • Glabellar frown lines and forehead wrinkles.
  • Drooping or lowered eyebrows and asymmetry in brow position.
  • Sagging of cheeks and chin area; contouring of the jawline and lower face (gravitational ptosis).
  • Skin laxity of the chin, neck and décolleté area.
  • Wrinkles and skin laxity of the neck and upper chest.
  • Body skin laxity and contour support in areas such as abdomen, buttocks, inner thighs, legs, arms and chest, including irregularities after liposuction or liposculpture.
  • General facial and body skin rejuvenation where non-surgical lifting and tightening are desired in appropriately selected patients.

Composition

  • Active structural component: Polydioxanone (PDO) absorbable synthetic polymer threads (cog/barbed design).
  • Thread design: 4D 360° cog (multidirectional barbs along the full circumference of the thread).
  • Delivery system: Thin, flexible cannulas/needles (L- or W-type cannula depending on specific reference) in 19G and 21G sizes with 100 mm length, preloaded with PDO cog thread of approximately 150 mm length.
  • Material properties (from manufacturer literature for Velancia PDO lifting threads): biodegradable, fully resorbable via hydrolysis; biocompatible with human tissues; designed to stimulate collagen formation around threads and cogs.
  • No additional active pharmaceutical ingredient: the device is a mechanical lifting thread made only of PDO within sterile packaging.

Formulation

  • Medical device class lifting thread system composed of sterile, single-use PDO cog threads preloaded in cannulas/needles.
  • Thread type: Velancia 360° 4D Cog in cannula (COG PDO) with multidirectional barbs distributed around 360° of the thread surface.
  • Needle/cannula sizes as described in distributor and manufacturer materials: 19G x 100 mm and 21G x 100 mm with approximately 150 mm thread length and USP 1-0 or 2-0.
  • Implantation plane: subdermal/subcutaneous soft tissues of face and body, according to practitioner’s technique and training.
  • Intended users: trained and certified medical professionals experienced in thread-lifting procedures.

Packaging

  • Top Dermal product listing: Format specified as 1 pack x 4 pieces (4 preloaded PDO cog threads).
  • Koru Pharma Velancia COG documentation: package described as 1 box / 5 packs x 4 EA (total 20 threads per manufacturer box; distributors may sell individual packs).
  • Each thread is supplied sterile in an individual blister or pouch, preloaded in a cannula/needle and packed in sealed primary packaging inside secondary cartons.
  • Outer packaging is labelled with product name (Velancia COG PDO Thread / Velancia 360 4D COG), manufacturer (Koru Pharma), lot/batch number and expiry date, according to manufacturer catalogue.
  • Packaging is intended for professional use and to maintain sterility until opening; single use only.

Usage

  • Device is applicable only by injection and must be used exclusively by suitably trained and certified medical professionals experienced in PDO thread-lifting techniques.
  • Treatment planning includes assessment of facial or body area, skin laxity and vector mapping to determine the number of threads (Top Dermal notes typical ranges of approximately 8 to 25 threads depending on area and degree of sagging).
  • After skin preparation and antisepsis, local or topical anaesthesia is applied according to practitioner preference and patient needs.
  • The preloaded cannula/needle containing the Velancia 360° 4D COG PDO thread is inserted into the subdermal plane along predetermined vectors; the cannula/needle is then withdrawn, leaving the PDO thread in place to create an internal support framework.
  • Threads may be adjusted or gently tensioned according to the desired lifting effect, following the manufacturer’s and distributor’s guidance and practitioner’s training.
  • After insertion, light moulding along the vector may be performed to adapt tissues to the newly created support structure, in line with standard PDO thread-lift practice.
  • Post-procedure recommendations (per product literature and standard thread-lift guidance) typically include avoiding strong facial movements, massage of treated areas, and high-intensity physical activity for a certain period as advised by the practitioner.
  • Further aesthetic procedures (such as laser resurfacing, electric muscle stimulation, RF lifting, mesotherapy or fillers) can generally be performed after an interval (Top Dermal mentions that some procedures can be resumed from about 1 month post-treatment), according to practitioner judgement.
  • Threads are single-use, sterile medical devices and must not be resterilized or reused; disposal should follow local clinical waste regulations.

Contraindications

  • Acute infectious diseases such as influenza and other febrile illnesses (as listed under “Contra-indications to mesothreads” in distributor information).
  • Herpetic or impetiginous eruptions in the area to be treated.
  • Oncological (malignant) diseases noted as a contraindication in the product literature.
  • Coagulation disorders or significant clotting abnormalities.
  • Active skin inflammation, infection, or dermatologic disease at or near the planned thread insertion sites.
  • Any other general contraindications to minimally invasive thread-lifting procedures as determined by the treating medical professional (e.g., severe systemic disease, known hypersensitivity to PDO or local anaesthetics, where applicable), even if not explicitly listed in the product literature.

Adverse Effects

  • Product literature emphasises minimal trauma: thin, flexible cannulas/needles that separate rather than cut tissues, resulting in very small post-injection marks that typically disappear quickly.
  • Temporary redness and minor injection marks at insertion points are described as possible but usually resolving within a few hours after the procedure.
  • Manufacturer and distributor descriptions state that Velancia mesothreads are 100% biocompatible with tissue and claim no risk of allergic reaction in the provided documentation.
  • Distributor materials highlight low risk of hematomas and infiltration compared with more invasive lifting techniques, although small bruises or swelling remain possible with any needle/cannula procedure.
  • As with other PDO thread-lifting procedures, potential complications such as infection, asymmetry, thread visibility or palpability, irregular contours, or prolonged pain are recognised in clinical practice but are not detailed in the specific Velancia product marketing texts and must be managed according to standard medical guidelines.
  • No formal, quantified adverse event rates specific to Velancia 360° 4D COG PDO threads are publicly listed in the manufacturer catalogue or distributor product pages reviewed.

Storage Conditions

  • Manufacturer catalogue for Velancia lifting threads specifies: avoid direct sunlight and humidity, store at a temperature of 15–25 °C.
  • Threads should be kept in their original sterile packaging until use and protected from mechanical damage and contamination.
  • Storage must comply with local medical device storage regulations and the expiry date indicated on the packaging.

Duration

Koru Pharma Velancia COG documentation states that the rejuvenating effect of Velancia COG lifting threads lasts for approximately 2 years, while distributor product information for Velancia 360\u00b0 4D COG (Cannula Cog) describes a lasting lifting effect of about 1.5\u20132 years. PDO threads themselves are reported to fully biodegrade over roughly 6\u20139 months via hydrolysis, with the collagen framework that forms around the threads providing the extended lifting and tightening effect over this 1.5\u20132 year period. Actual duration depends on patient factors, treatment area and technique.

Onset

Product descriptions for Velancia 360\u00b0 4D COG (Cannula Cog) state that lifting and wrinkle-reduction effects are visible immediately or shortly after the procedure, with both the lifting effect and gradual skin rejuvenation becoming noticeable right after treatment and on the following day.
