How is PLLA (poly-l-lactic acid) different from traditional dermal fillers?

Traditional dermal fillers provide immediate volume by physically filling an area. PLLA is a collagen biostimulator that works gradually by stimulating your skin's own collagen production for subtle, natural-looking improvement over time.

What results can I expect, how soon will I see them, and how many sessions are needed?

PLLA results develop gradually. Initial fullness from the treatment fluid settles in a few days, while collagen changes begin to appear subtly after several weeks and continue to improve over the next few months. A series of 2 to 3 sessions spaced about 4 to 6 weeks apart is typically advised based on clinical evaluation.

How Long Does the Treatment Last? Is it permanent?

Results from PLLA treatment can last up to two years or more once collagen has been established. It is not permanent, but the results are long-lasting compared with many non-surgical facial rejuvenation treatments.

Is the Poly-L-Lactic Acid Injection Painful?

The treatment is designed to be comfortable. A strong topical numbing cream is applied before the procedure, and the PLLA solution is prepared with anaesthetic for additional comfort during injection.

What is the downtime, aftercare, and are there potential side effects?

Mild swelling, redness, or bruising at the injection site is common and usually settles within a few days. After treatment, patients are advised to massage the treated areas, avoid prolonged sun exposure, intense heat, and vigorous activity for 24 to 48 hours, and follow their doctor's aftercare instructions.

Who is an ideal candidate, and who should avoid this treatment?

Suitable candidates usually have facial volume loss, structural thinning, or skin laxity and prefer gradual, natural-looking improvement. Treatment is not recommended for people who are pregnant or breastfeeding, have active skin infection or inflammation, known sensitivity to poly-L-lactic acid, autoimmune disorders, abnormal scar formation, or require treatment in delicate areas such as the under-eye region.

Can it be combined with other aesthetic treatments?

Yes. Depending on your skin condition and goals, PLLA collagen biostimulator treatment may be combined with other aesthetic treatments as part of a personalised medical plan after assessment by the doctor.

Is This PLLA Treatment Reversible? What if I don't like the results?

PLLA works by stimulating collagen rather than by placing a dissolvable gel, so it is not considered reversible in the same way as hyaluronic acid filler. This is why a careful consultation, gradual treatment planning, and precise placement by an experienced doctor are important.

The Treatment

What Is PCL Collagen Biostimulator (M) and How Does It Work?

Polycaprolactone (PCL) Collagen Biostimulator (M) is an FDA-approved, is a non-surgical injectable treatment for suitable patients concerned about age-related facial volume changes and reduced definition. It is designed to support facial contours while encouraging collagen stimulation over time.

At Asimont Clinic, every treatment begins with a doctor-led assessment of your facial anatomy, concerns and suitability. Your treatment plan is tailored to support balanced, natural-looking refinement.

The Science

PCL Collagen Biostimulator (M): A Dual-Action Approach

Unlike treatments that rely solely on gradual collagen stimulation, PCL Collagen Biostimulator (M) is designed to provide both initial structural support and progressive collagen stimulation.

1. Initial Support: The gel carrier provides immediate support to the treated area, helping to restore facial contour and balance.

2. Collagen Stimulation: The microspheres act as a scaffold that encourages the skin’s natural collagen response over time.

3. Gradual Refinement: As the gel carrier is gradually absorbed, newly formed collagen helps maintain support. The treatment effect evolves progressively and should be reviewed as part of your personalised plan.

Why Choose PCL Collagen Biostimulator (M)?

What May This Treatment Help With?

This injectable procedure is an ideal choice for the individual seeking to support:

Facial Volume Support

Support for age-related volume changes in selected areas of the face.

Supporting Age-Related Facial Volume Changes

As we age, changes in facial fat, bone and skin structure can make areas such as the cheeks and temples appear less supported. For suitable patients, PCL Collagen Biostimulator (M) may be used as part of a personalised plan to support facial volume and restore a more balanced facial appearance. The areas treated and amount used are determined after a doctor-led assessment.

Refined Facial Contours

Improved definition and balance in areas such as the cheeks, jawline or chin, where clinically appropriate.

Enhancing Facial Definition and Balance

Facial contours can change over time, particularly through the mid-face, chin and jawline. Where clinically appropriate, this treatment may support definition in selected areas while respecting your natural facial proportions. The aim is not to alter your appearance dramatically, but to create balanced refinement based on your individual anatomy and aesthetic concerns.

Gradual Collagen Stimulation

Encouragement of the skin’s natural collagen response over time.

Supporting Collagen Renewal Over Time

This treatment is designed to support facial structure while encouraging the skin’s natural collagen response over time. As collagen develops, the treatment effect may evolve gradually rather than being limited to the initial correction. Individual response, treatment area and maintenance needs vary, and will be discussed during consultation.

Skin Quality Support

Support for a firmer, smoother-looking skin appearance as part of a personalised treatment plan.

Supporting Firmer, Smoother-Looking Skin

Collagen is an important component of the skin’s underlying structure. For suitable patients, collagen stimulation may support improvements in the appearance of skin firmness and smoothness over time. Results vary between individuals and depend on factors including skin condition, treatment plan and lifestyle.

Where It’s used

Common Treatment Areas

PCL Collagen Biostimulator (M) may be considered for selected facial areas following a doctor-led assessment:

Cheeks and Mid-Face

May support age-related volume changes and facial contours.

Temples

May be considered for temple hollowing where clinically appropriate.

Nasolabial folds

Softens deep smile lines for a smoother, more youthful appearance.

Jawline and lateral mid-face

What To Expect

How Is PCL Collagen Biostimulator (M) Administered at Asimont Clinic?

Step 1

Your Personalised PCL Collagen Biostimulator (M) Consultation

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 PCL Collagen Biostimulator (M). We will discuss what to expect from the procedure, the results, the number of sessions, and create a personalised treatment plan.

Step 2

Cleanse & Numb

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.

Step 3

The PCL Collagen Biostimulator (M) Injection Session

The PCL Collagen Biostimulator (M) 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 PCL Collagen Biostimulator (M) injection process, usually lasts 30 to 60 minutes.

Step 4

Post-Treatment Guidance

Mild swelling, redness, or bruising at the injection site is normal and usually subsides within a few days. Our doctor will provide advice for aftercare. We also advise avoiding prolonged sun exposure, intense heat, or vigorous activity for 24 to 48 hours to ensure the best possible results.

How Soon Will I See Results?

Onset and Duration of Results

PCL Collagen Biostimulator (M) is designed to work in two phases. Its CMC carrier gel provides an initial contouring effect, while the PCL microspheres support gradual collagen formation. You may notice a change soon after treatment, but the appearance continues to settle and evolve over the following months. The degree and duration of the result will vary according to the individual, treated area and treatment plan.

The PCL Collagen Biostimulator (M) Timeline: What to Expect and When

An initial contouring effect may be visible after treatment, although temporary swelling or bruising can influence the early appearance. Over approximately two to three months, the CMC carrier gel is gradually resorbed while newly formed collagen increasingly contributes to the result. The day-one appearance should therefore not be considered the final outcome.

A Gradual Collagen Response

PCL Collagen Biostimulator (M) does not rely solely on its initial filling effect. Its PCL microspheres are designed to stimulate the formation of new collagen, helping to support the treated area as the carrier gel gradually fades. This response develops progressively and will differ between individuals.

How Long Can the Results Last?

Results from PCL Collagen Biostimulator (M) may last for up to 24 months. Actual longevity varies according to factors such as the treated area, amount used, injection technique, age, lifestyle, metabolism and individual response. Results cannot be guaranteed for a fixed period.

Recommended Treatment Frequency

PCL Collagen Biostimulator (M) is often planned as a single treatment rather than a fixed series of sessions. A follow-up review allows your doctor to assess how the result is settling and whether any further correction may be appropriate. Future maintenance should be based on individual reassessment rather than an automatic schedule.
