Today we are talking Smooth Threads!

By Jill Charles, NP

I love this procedure based on the variety of uses and amazing results. Please read below for additional details!

Polydioxanone (PDO) is a suture material that has been used for over 30 years in the surgical setting. PDO has been widely used in cardiovascular surgery, pediatric surgery, orthopedic surgery and dental procedures. The esthetic industry uses solid filler smooth PDO threads due to their versatility and ability to address a multitude of cosmetic concerns.


  • Neocollagenesis is the process of collagen production that occurs as the threads start to break down. This in turn improves skin elasticity and blood circulation.
  • Improves the support that the skin needs to regenerate which can address cellulite, wrinkles and crepey skin.
  • Subcision of scar tissue releases fibrotic strands that are anchoring scars to underlying tissue
  • Increases cell metabolism and delays skin aging

The PDO threads are placed under the skin by a trained professional and will slowly start to break down about 1 month post-procedure. By 3-6 months, there is a maximum production of collagen as the threads have completely broken down.


  • Smoothing of wrinkles (glabella, radial lip lines, oral commissure, marionette lines)
  • Improved appearance of scars and stretch marks
  • Skin rejuvenation
  • Improved elasticity and texture
  • Replacement of volume loss and lifted skin
  • Defined vermillion border
  • Smoothing and tightening of double chin

As you can see, there are many advantages to adding solid filler smooth PDO threads to your practice! These are easy to add on to the services you already provide to exponentially improve outcomes and patient satisfaction. Once properly trained, placement can be quick, easy and lucrative. I highly recommend training through American Academy of Facial Esthetics so that you too, can start treating your patients with solid filler PDO smooth threads!
