Are PDO Threads Approved by Health Canada? What You Need to Know

PolyDOT Extendable Sutures (PDO threads) are increasingly popular in aesthetic and reconstructive procedures, but many users ask: are PDO threads approved by Health Canada? This article explores the regulatory status, clinical uses, safety, and real-world insights on PDO threads in Canada as of 2025.

What Are PDO Threads?

PDO threads are absorbable sutures made from polypropylene, widely used in dermatology and plastic surgery for skin tightening and lifting. Though not traditionally classified as implants, their use in facial and body treatments has grown rapidly. Unlike synthetic implants, PDO threads degrade naturally over 6–18 months, relying on the body’s healing process.

Health Canada’s Regulatory Stance on PDO Threads

Health Canada does not list PDO threads in its official database of approved medical devices for permanent body modification or internal use. They are classified as medical sutures, not implants, and thus fall under general medical device regulations. While not explicitly banned, PDO threads do not receive formal approval like some implants—meaning their use is based on existing regulatory frameworks rather than dedicated endorsement.

Importantly, Health Canada approves certain surgical sutures and absorbable materials, but PDO threads are not included in their approved product list. This distinction impacts insurance coverage and clinical guidelines, though they remain widely used under standard medical practice.

Medical Uses and Safety Profile in Canada

In Canada, PDO threads are commonly used in non-implant aesthetic procedures such as facelifts, midface lift, and body contouring. They help stimulate collagen production, improving skin elasticity and reducing sagging without foreign permanence. Clinical studies and dermatologist reports confirm their safety when applied by licensed professionals.

Serious adverse events are rare but can include infection, delayed absorption, or scarring—especially with improper technique. Patients should consult regulated practitioners and obtain informed consent. Health Canada recommends following approved protocols to minimize risks.

Comparing PDO Threads to Other Thread-Based Implants

PDO threads differ from permanent thread implants like PDS (PearlDOT) or PLASTI-GLIDE, which are explicitly approved in Canada. While PDOs offer temporary lifting with natural absorption, permanent implants require formal approval and carry additional regulatory scrutiny. Both have distinct roles: PDOs for non-invasive skin rejuvenation; implants for structural support in surgery.

Navigating Regulations: What Patients Should Do

If considering PDO threads, verify your provider’s credentials and clinic’s compliance with Canadian medical standards. Confirm device type and usage—absorbable, non-implant PDOs are generally safe under professional care. Always review patient information leaflets and discuss potential side effects openly.

PDO threads are not approved by Health Canada as a distinct therapeutic category, but their use aligns with approved medical practices when applied correctly. Staying informed ensures safe, effective outcomes in aesthetic and reconstructive care.

Take charge of your treatment journey—choose certified providers, ask questions, and verify regulatory status before undergoing PDO thread procedures.
