At Asimont Clinic, PLLA Collagen Biostimulator (童顏針) is a non-surgical injectable that uses poly-L-lactic acid to stimulate collagen production and improve skin texture over time. Suitable for those with volume loss or ageing concerns, it promotes gradual, natural-looking results rather than instant volumisation, supporting long-term skin rejuvenation through collagen renewal.
Our PLLA protocols are developed by our Medical Director, Dr. Vipatsorn (Pat) Shutchaidat. With her medical background and international training at the Royal College of Surgeons, Dr. Pat applies an intricate understanding of facial anatomy to ensure every biostimulator injection is placed with precision for natural, balanced results.

Patients in Singapore often choose this PLLA treatment because the results are exceptionally natural. There is no risk of the “overfilled” look that can sometimes occur with hyaluronic acid fillers. The PLLA microparticles are injected deep into the dermis, where they kickstart natural collagen production.
Over a period of weeks and months, your skin gradually becomes firmer, plumper, and smoother from within. This subtlety is what makes it a premier choice for comprehensive facial rejuvenation.
Poly-l-lactic acid is an FDA-approved, biocompatible, and biodegradable compound used in medical injectables to promote collagen formation in the deeper layers of the skin. Once injected, PLLA particles stimulate fibroblasts, the skin’s collagen-producing cells encouraging gradual tissue strengthening and volume restoration in targeted areas. The changes that occur are typically subtle and cumulative, allowing for outcomes that integrate with the skin’s natural healing and structural renewal processes.
Unlike instant fillers, Poly-L-Lactic Acid (PLLA) works by stimulating your skin’s own biological renewal.
1. Immediate Micro-Volume: The initial fullness you see is from the sterile water used to suspend the PLLA particles. This water is naturally absorbed within 48-72 hours, which is a normal part of the process.
2. Fibroblast Activation: Once the water is absorbed, the PLLA micro-particles remain in the dermis, acting as a scaffold that triggers your fibroblast cells (collagen factories) to start production.
3. Structural Restoration: Over 4 to 8 weeks, the PLLA is replaced by a new, healthy network of your own Type 1 collagen, providing a lift that lasts up to 24 months.
This injectable procedure is an ideal choice for the individual seeking to support:
Restoration of age-related volume loss in the mid- or lower face
One of the primary uses of this PLLA treatment is to address generalised facial volume loss. As we age, we lose fat pads and bone mass in the face, leading to a sunken or “deflated” appearance, particularly in the cheeks and temples. This treatment works to rebuild this underlying structure by using PLLA, restoring youthful curves and fullness for a more youthful contour.
Improvement in skin firmness and structural support
The loss of collagen and elastin leads to the skin sagging. By stimulating collagen production, this injectable effectively “thickens” and tightens the skin from the inside out. This new structural support helps to lift sagging skin (jowls) and improves the appearance of fine lines and wrinkles, such as smile lines (nasolabial folds) and marionette lines, by reinforcing the skin’s foundation.
Smoother appearance of nasolabial folds or sunken areas
As facial volume is lost over time, the skin can sag, leading to sunken areas of the face and the deepening of lines and wrinkles, such as nasolabial folds. This poly-l-lactic acid collagen stimulator works by stimulating collagen production deep within the skin. This process rebuilds the underlying structure, restoring lost volume and lift. The results are a natural-looking softening of these folds and a smoother, more youthful facial contour, addressing these key signs of ageing from within.
General collagen support for facial skin affected by thinning or laxity
Beyond just volume and lift, the surge in new collagen from a PLLA treatment has a profound effect on overall skin texture and quality. Patients often report that their skin feels firmer, looks more radiant, and has a healthy “glow.” The improved skin integrity can also help to minimise the appearance of some scars and textural imperfections over time.
The PLLA injectable may be used in the following regions:
It’s important to note that this PLLA injectable is a versatile collagen stimulator. Because it stimulates collagen production wherever it is placed, an experienced doctor at our Singapore clinic will not just “spot-treat” individual lines. Instead, they will assess your unique pattern of facial hollowing and laxity to provide global facial rejuvenation for a more harmonious, balanced, and natural-looking result.
Our aesthetic doctor will conduct a thorough evaluation of your skin condition, facial structure, and aesthetic goals. This is where we determine if you are a good candidate for this PLLA treatment. We will discuss what to expect from the procedure, the results, the number of sessions, and create a personalised treatment plan.
The treatment areas of the face are thoroughly disinfected to ensure safety and clinical hygiene. A strong topical numbing cream is a standard part of the procedure and is applied to the skin for 20-30 minutes. This ensures the procedure is as comfortable as possible.
The poly-l-lactic acid (PLLA) solution, which is pre-mixed with an anaesthetic (lidocaine) for added comfort, is injected into the deep tissue layers of the skin. This precise placement is key to stimulating collagen production in the right foundational layer. The procedure itself, involving the PLLA injection process, usually lasts 30 to 60 minutes.
Mild swelling, redness, or bruising at the injection site is normal and usually subsides within a few days. Our doctor will provide a crucial piece of aftercare: gentle facial massage (the “Rule of 5”). We also advise avoiding prolonged sun exposure, intense heat, or vigorous activity for 24 to 48 hours to ensure the best possible results.
A common question is “how long does this PLLA treatment take to work?” You may notice some immediate fullness, but this is mostly sterile water from the injection and will recede within a few days. The true results from new collagen growth begin to appear subtly around 6 weeks, with progressive enhancement over the next few months as your skin rebuilds.
The biostimulatory effects of poly-l-lactic acid persist for several months after your final treatment session. This is a key part of the process, as the PLLA particles continue to keep the fibroblast cells active, ensuring the new collagen matrix becomes dense, strong, and provides lasting structural support.
This is a key benefit. Once established, the results from this PLLA injectable can be very long-lasting, lasting up to two years, or even longer for some patients. The longevity is the reason it is a preferred treatment for facial rejuvenation, as patients can enjoy these long lasting results for up to two years or more. This makes it one of the most valued non-surgical treatments available for facial volume. These results can last up to two years.
For optimal results, a series of 2 to 3 sessions is typically advised, spaced about 4 to 6 weeks apart based on clinical evaluation. This is because collagen production happens in stages. This approach allows the doctor to gradually build volume and structure for a more natural, balanced, and more youthful outcome.
As with all medical treatments, suitability depends on individual health, goals, and skin condition. The following guidelines outline who may benefit from this treatment and who should avoid it.
The ideal candidate for this treatment is typically someone (in their 30s or older) noticing the global signs of ageing. This includes volume loss and skin laxity, such as hollowing temples, flat cheeks, and sagging jowls. It is perfect for those who want a more youthful appearance that is gradual, natural-looking, and provides long lasting results.
A thorough medical history review is essential. Is this treatment safe for everyone? No. It is not recommended for those who are pregnant or breastfeeding. Patients with active skin infections, uncontrolled autoimmune disorders, or a history of keloid (abnormal) scarring should not undergo this procedure.

This is the most important distinction. Traditional dermal fillers, such as those made from hyaluronic acid fillers, are gels that physically “fill” a space to provide immediate volume. They are like “renting” volume, as the body breaks them down over 9-18 months. This poly-l-lactic acid (PLLA) is an FDA-approved biostimulator; it is not a filler.
It works by stimulating your body’s own natural collagen production. It acts as a “seed” that tells your skin to rebuild its own structural foundation. This means the results are gradual, subtle, and natural-looking, addressing the underlying cause of volume loss and skin laxity. Instead of renting, you are “building” your own new collagen.
You can expect a gradual restoration of facial volume, a lifting of sagging skin, and an improvement in skin texture and firmness. The results are not instant.
Timeline: Immediately after the injection, you may see some fullness, which is just sterile water and will be absorbed within a few days. The real results from your new collagen start to appear 1 to 3 months after your first session. These results will continue to improve for up to 6 months after your final treatment.
Sessions: For optimal, long-lasting results, a series of 2 to 3 treatment sessions is typically required, spaced about 4 to 6 weeks apart. This “stacking” approach ensures a robust and natural collagen foundation is built over time.
The results of this poly-l-lactic acid treatment are very long-lasting, with clinical studies showing effects lasting up to two years or more after the final treatment session. This is because the treatment creates a new framework of your own natural collagen.
It is not considered permanent because the natural ageing process continues. Your body will still slowly break down collagen over time. Many patients choose to have a single maintenance session every 18-24 months to maintain their collagen levels and prolong the natural-looking results.

Discomfort is typically minimal and well-tolerated. At Asimont Clinic, we prioritise your comfort by applying a strong topical numbing cream to the treatment areas before the procedure.
Additionally, the poly-l-lactic acid (PLLA) solution is mixed with lidocaine, a local anaesthetic, which further numbs the area during the injection. Most patients report feeling only mild pressure or a brief pinching sensation.
This PLLA treatment is a minimal downtime procedure, but proper aftercare is essential for the best results. The minimal downtime is a key benefit.
Downtime: Most patients resume normal daily activities immediately. You may experience temporary, mild side effects such as swelling, redness, tenderness, or bruising at the injection sites. These typically resolve within a few days. We advise avoiding strenuous exercise, saunas, and excessive alcohol for 24-48 hours to minimise swelling.
Side Effects: This PLLA treatment is an FDA-approved treatment with a high safety profile. The most common side effects are the temporary injection-site reactions mentioned above. A rare side effect is the formation of small, non-visible nodules (lumps) under the skin.
Aftercare (The “Rule of 5”): The risk of nodules is dramatically reduced by following the crucial “Rule of 5”. You must massage the treated areas for 5 minutes, 5 times per day, for 5 days. This ensures the PLLA particles are distributed evenly, promoting a smooth, uniform collagen response.
The ideal candidate for this PLLA injectable is someone concerned with the global signs of facial ageing, such as generalised volume loss, hollowing in cheeks or temples, and skin laxity (sagging). It is perfect for individuals who want a gradual, natural-looking rejuvenation rather than an instant or “done” look.

This PLLA injectable is exceptionally versatile for restoring structure and volume to the face. Its primary treatment areas of the face include:
Many patients look at PLLA’s price in isolation, but the most natural results often come from a comprehensive rejuvenation plan. Your doctor may suggest a package that includes PLLA as the ‘anchor’ treatment alongside other therapies.
Is it worth combining it with other treatments?
Yes. PLLA is an excellent foundational treatment that ‘rebuilds the framework’ of the face.It is often a key part of a comprehensive, long-term facial rejuvenation plan. By combining it, you address different aging concerns simultaneously, which can sometimes be more cost-effective than treating them separately over years:
Note: Your doctor will advise on the correct timing and sequence to ensure your treatment plan fits your budget and goals.
This is a critical point to understand: No, this PLLA treatment is not reversible in the same way hyaluronic acid (HA) fillers are. There is no “dissolving enzyme” for PLLA. The treatment works by stimulating your body to create its own collagen.
The PLLA microparticles themselves are naturally absorbed and gone within months, but the new collagen framework your body has built is what remains. This is precisely why the results are so natural and gradual, as it’s impossible to look “overfilled.” It is also why choosing a highly skilled, experienced injector is paramount.
