PDO Collagen Stimulator
A PDO collagen stimulator uses microscopic polydioxanone (PDO) particles to activate the skin’s own collagen production — improving firmness, texture and elasticity gradually over time. Administered by MOH-licensed doctors at IVI Medical Clinic Singapore.
A PDO collagen stimulator is an injectable treatment that uses microscopic polydioxanone (PDO) particles to activate the skin’s own collagen production. Rather than simply filling a line, it works with the body’s natural healing response to improve firmness, texture and elasticity gradually over time.
How does a PDO collagen stimulator work?
The treatment contains microscopic PDO particles suspended in a carrier solution. Following injection:
- PDO microspheres are placed within the treatment area.
- The body’s natural healing response is activated around them.
- Fibroblasts — the cells responsible for collagen — are stimulated to produce new collagen.
- Gradual collagen remodelling helps improve skin firmness and texture.
- As the PDO material biodegrades, the newly formed collagen continues to provide structural support to the skin.
PDO (polydioxanone) is a biodegradable polymer that has been used safely in medical applications for many years, and it is fully broken down by the body over time.
What areas can it treat?
A PDO collagen stimulator may be considered in suitable patients seeking collagen stimulation in areas such as:
- Under-eye area (tear trough)
- Cheeks
- Nasolabial folds and marionette lines
- Temples
- Jawline
- Neck and décolletage
- Hands
How is it different from a dermal filler?
A dermal filler restores volume immediately by adding a gel beneath the skin. A PDO collagen stimulator works differently — its primary purpose is to stimulate your own collagen production rather than to replace lost volume directly. Results therefore appear more gradually, but as they are built from your body’s own collagen, the improvement in skin quality can look and feel natural.
What to expect from treatment
Your treatment begins with a consultation to assess your skin concerns and confirm whether the treatment is suitable for you. The procedure is performed by a qualified doctor and typically takes around 30 to 45 minutes, depending on the area. A topical numbing cream may be applied for comfort before the PDO collagen stimulator is injected into the targeted areas. Afterwards you may notice mild redness, swelling, bruising or tenderness at the injection sites, which are generally temporary and settle within a few days. As the treatment supports natural collagen production, improvements develop gradually over the following weeks, and your doctor may recommend follow-up sessions based on your goals.
PDO Collagen Stimulator FAQ
Is a PDO collagen stimulator a dermal filler?
No. Although it is injected, its primary purpose is to stimulate your own collagen production rather than to simply replace lost volume the way a hyaluronic acid filler does. The improvement is built gradually from your body’s own collagen, which is why results develop over several weeks rather than appearing immediately.
What is a PDO collagen stimulator made of?
It is made from polydioxanone (PDO) — a biodegradable polymer that has been used safely in medical applications, including surgical sutures, for many years. The PDO is delivered as microscopic particles suspended in a carrier solution and is fully broken down by the body over time, leaving no permanent material behind.
How many sessions are required?
The recommended number of sessions depends on your individual skin condition and treatment goals. A typical course is around three to four sessions, spaced several weeks apart, to build a progressive result. Your doctor will advise a personalised plan during your consultation.
When will I see results?
Because the treatment works by stimulating your own collagen, improvements are gradual. Some patients notice subtle changes in the first few weeks, with continued improvement in firmness and texture developing over the weeks and months that follow as new collagen forms. Individual results vary.
How long do results last?
The PDO material itself is gradually biodegraded by the body over several months, but the collagen your skin produces in response continues to provide support beyond that. Results commonly last in the region of six to twelve months, and maintenance sessions can help sustain the effect over time. Longevity varies with individual factors and the area treated.
Is there any downtime?
Downtime is usually minimal. Mild redness, swelling, bruising or tenderness at the injection sites may occur and generally settles within a few days. Most patients are able to return to their normal routine soon after treatment.
Can a PDO collagen stimulator be combined with other treatments?
Yes. Depending on your individual needs, a PDO collagen stimulator may be combined with other doctor-recommended aesthetic treatments as part of an overall plan — for example, alongside skin boosters or energy-based devices to address different aspects of skin quality.
