PDO threads are a popular non-surgical treatment used to lift and tighten sagging skin while also improving overall facial structure. One of the most common questions patients ask is how long PDO threads last and whether the results are temporary or long-lasting. The answer depends on several factors, including the type of threads used, the treatment area, and individual skin characteristics.
Understanding PDO Threads
PDO threads are made from polydioxanone, a biocompatible material that has been safely used in medical sutures for many years. In aesthetic treatments, these threads are placed under the skin to provide an immediate lifting effect and to stimulate collagen production over time.
Unlike surgical facelifts, PDO thread treatments are minimally invasive and do not involve removing excess skin. Instead, they reposition and support facial tissue while encouraging natural collagen regeneration, which helps maintain results after the threads dissolve.
How Long Do PDO Threads Physically Last
The threads themselves are temporary. In most cases, PDO threads dissolve naturally in the body within about 4 to 6 months. During this time, they gradually break down into harmless substances that are absorbed by the body.
However, even though the threads dissolve within a few months, the results of the treatment typically last much longer. This is because the threads stimulate collagen production around the treated area, creating a supportive internal structure that remains after the threads are gone.
How Long Do the Results Last
While the threads dissolve in a few months, the visible lifting and tightening effects usually last anywhere from 12 to 18 months for most patients. In some cases, results may last slightly longer depending on individual factors such as skin quality, age, and lifestyle habits.
The long-term improvement is primarily due to new collagen formation. This collagen acts like a natural support system for the skin, helping maintain firmness and lift even after the threads are no longer present.
Factors That Affect Longevity
Several factors can influence how long PDO thread results last. Skin condition plays a major role, as patients with good skin elasticity tend to maintain results for a longer period. Age is another factor, since younger skin typically produces collagen more efficiently.
Lifestyle habits also make a difference. Sun exposure, smoking, hydration levels, and skincare routines can all impact how well the skin maintains its structure after treatment. Patients who follow a healthy lifestyle often enjoy longer-lasting results.
Treatment technique is also important. The placement and type of threads used can affect both the initial lift and the longevity of results. At Blu Cocoon Medspa, treatments are customized based on facial anatomy and aesthetic goals to ensure balanced and natural outcomes.
Maintenance and Touch-Up Treatments
Although PDO thread results are long-lasting, they are not permanent. Many patients choose to have maintenance treatments after 12 to 18 months to preserve their results and continue collagen stimulation.
Touch-up sessions can help maintain skin firmness and prevent further sagging over time. In some cases, smaller treatments may be used to enhance specific areas rather than repeating a full procedure.
What to Expect Over Time
Immediately after treatment, patients notice an instant lifting effect due to the physical support of the threads. Over the following weeks, collagen production increases, which improves skin texture, firmness, and overall contour.
As the threads gradually dissolve, the skin retains much of the improved structure due to the newly formed collagen. This is why results continue even after the threads are no longer present.
