PDO Threads or Fillers? Choosing the Right Treatment for Your Goals

By: Annie Nguyen

8/20/2026

Are you noticing sagging skin, lines and wrinkles, or a face that just doesn't look as lifted as it used to? Both PDO threads and dermal fillers can help, and the right choice depends on your needs. Dermal fillers restore lost volume, while threads provide structural lift by repositioning the skin and encouraging new collagen growth over time. 

 At My Aesthetics Intelligence in Dallas, TX, double-board-certified nurse practitioner Annie Nguyen offers both options and can help you figure out which fits your goals. Call today to schedule a consultation and get a personalized recommendation. 

Why skin changes with age 

As skin ages, it loses general volume and structural support. Fat pads in the cheeks and temples shrink, leaving a flat appearance. At the same time, declining collagen and elastin cause the tissue to lose firmness, leading to sagging skin along areas such as the jawline, cheeks, and neck. 

These two changes often happen at the same time, causing wrinkles, hollow cheeks, and the appearance of jowls. Some patients need more volume, some need more lift, and many need a bit of both. PDO threads and dermal fillers each address these issues in their own way. 

What are PDO threads and dermal fillers? 

So, what are PDO threads? They're thin, dissolvable sutures made from polydioxanone, a material that's been used safely in medicine for decades. Annie inserts the threads beneath the skin using a fine needle, then gently lifts sagging tissue. The threads also boost collagen production as they dissolve over the following months. 

Dermal filler treatment works differently. Rather than lifting tissue, filler adds volume directly where it's needed, smoothing lines and wrinkles and restoring fullness to hollow areas like the cheeks or temples. Most fillers are made from hyaluronic acid (HA), giving results that look soft and natural. 

These two treatments solve different problems, which is why the right one depends on your main concern. If your skin has dropped or sagged, PDO threads may make the biggest difference. If you've lost volume without much sagging, a dermal filler treatment in Dallas can be a better starting point. Many patients combine both for a more complete refresh. 

How Ultherapy fits in 

Many patients considering PDO threads or fillers may also be candidates for an advanced treatment called Ultherapy. While fillers restore lost volume and PDO threads provide a lifting effect, Ultherapy in Dallas uses focused ultrasound energy to boost collagen production within the skin. It can be an excellent option for patients experiencing mild to moderate sagging skin who want gradual tightening without injectables. 

Because Ultherapy works over several months rather than providing an immediate lift, some patients use it as a starting point, or as a way to maintain results in between. Annie can help you decide whether it belongs in your plan.
