What Are PDO Threads? Lift, Support & Collagen Basics

Educational guide for U.S. readers. This content is for information only and not a substitute for professional medical advice.

What are PDO threads?

PDO (polydioxanone) threads are ultra-fine, biodegradable sutures that are carefully placed under the skin by a trained professional to provide support and encourage a smoother, lifted look. PDO is a material long used in medical sutures and naturally dissolves over time.

How do they work?

  • Mechanical support: Threads create an internal “scaffold” to help refine contours in targeted areas.
  • Collagen stimulation: As threads dissolve, they may encourage your skin’s own collagen production, supporting firmer, more supple-looking skin over time.
  • Biodegradation: PDO threads gradually break down and are safely absorbed by the body.

Common thread types (at a glance)

  • Smooth/mono: Fine threads used in multiples for subtle skin support and texture refinement.
  • Twisted/screw: Coiled threads that provide added “fill” effect in focused areas.
  • Barbed/cog: Threads with tiny barbs that help anchor and lift tissue for contour support.

Who might consider PDO threads?

  • Mild skin laxity in areas like the cheeks, jawline, or brows.
  • Desire for a refreshed look with minimal downtime compared to more invasive procedures.
  • Interest in supportive treatments that pair well with skincare and other non-surgical options.

Important: Only a qualified professional can advise if PDO threads are appropriate for you based on your medical history, skin condition, and goals.

PDO Threads vs. Fillers: What’s the difference?

  • PDO Threads: Best for support and lift (scaffold effect) and a potential collagen boost.
  • Dermal Fillers: Best for volume and contour (e.g., cheeks, lips) and smoothing deeper folds.

These treatments can complement each other. Your provider may recommend one or a combination, depending on your goals.

What to expect: high-level overview

  1. Consultation: Your professional evaluates skin quality, laxity, and treatment goals.
  2. Treatment day: The area is cleansed; a numbing approach may be used. Threads are placed with a fine cannula or needle.
  3. Aftercare: You’ll receive guidance on avoiding pressure, heat, or strenuous activity for a short time and tips for sleeping positions and skincare.

Potential timeline

  • Immediate: A subtle supported look may be visible right away.
  • Weeks 4–12: Skin may appear progressively smoother as collagen support develops.
  • Longevity: Results vary by skin type, lifestyle, and thread type.

Safety notes

  • Always choose qualified, experienced professionals who follow sterile technique and use verified products.
  • Discuss your medical history, allergies, and expectations during consultation.
  • Follow personalized aftercare carefully for best outcomes.
