Stopping time may be impossible, but what about turning back the biological clock of your skin? Welcome to the era of “Regenerative” treatments that have revolutionized aesthetic medicine. The aim is no longer just to fill the gaps on the face with temporary gels; it is to remind the skin of its forgotten “youthful functions”. Here is the most powerful representative of this philosophy: PLLA Filler (Polylactic Acid).
Istanbul Nisantasi Medlook Polyclinic PLLA, one of the most advanced biotechnological solutions we offer to our patients, is also popularly known as “seeds of youth”. Because these micro-particles planted under the skin grow over time into fresh collagen fibers. In this comprehensive Pillar guide, What is PLLA filler, We answer the questions of how it is produced in a laboratory environment and how it starts a biological awakening on your face, in the light of science and with our “Sincere Expert” language.
What is PLLA (Poly-L-L-Lactic Acid)?
Although PLLA is new to the aesthetic world, it is a proven safe substance that has been used in medicine for more than 30 years. It is a synthetic polymer that is biocompatible (body-friendly) and biodegradable (dissolves over time). In fact, it is the main ingredient in dissolving surgical sutures (surgical threads). Scientists have discovered that this substance, when injected under the skin, triggers a powerful production of collagen, turning it into a “youth vaccine” in liquid form.
While conventional fillers act like an “implant” and take up space, PLLA acts like a “signaler”. It is not the substance itself that gives volume to the skin, but your own tissue triggered by the substance.
Scientific Overview: How Does the PLLA Mechanism of Action Work?
As Medlook experts, we explain this process to our patients with the analogy of “Seed and Garden”. Your skin is a garden and PLLA are the seeds planted there.
- Transplantation (Injection): PLLA micro-particles are mixed with sterile water and injected into the deep layer of the skin (subcutaneously or on the periosteum). The fullness you see on the first day is just water and is absorbed in 2-3 days.
- Awakening (Inflammation): When the water is gone, PLLA particles are left behind. The body recognizes these particles and starts to surround them. This is a controlled and desired state of “biological alarm”.
- Production (Neocollagenesis): Fibroblast cells gather around the particles and begin to intensively produce Type-1 Collagen.
- Result (Regeneration): Within months, the PLLA particles are completely dissolved and excreted, turning into water and carbon dioxide. But what is left behind is a strong, tight and bulky collagen network that has formed where the particles were.
PLLA Filler vs. Hyaluronic Acid Filler: What are the Differences?
This is the most confusing point for our patients. Why choose PLLA instead of conventional fillers? Here are the main differences:
| Feature | Classic Hyaluronic Acid (HA) | PLLA Filler (Sculptra etc.) |
|---|---|---|
| Working Principle | Physically fills space (Gel). | Biologically produces tissue (Stimulant). |
| Result Duration | Instantly visible. | Increases gradually (peaks at 3-6 months). |
| Persistence | Average 9-12 months. | Average 24 Months and over (Detailed Duration Information). |
| Texture Feel | Soft, gel-like consistency. | It is completely natural because it is your own tissue. |
Clinical Effects: What Does PLLA Do to Your Face?
The changes we observe after PLLA application in our Nişantaşı clinic are not limited to “fullness”. It provides a holistic increase in skin quality:
- Volume Restoration: Sunken temples, melted cheeks and a weakened jawline fill in naturally.
- Skin Tightening: The loosened skin is recovered “like wearing a corset” thanks to the collagen network woven from the inside.
- Tissue Thickening: With age, the “paper-thin” skin becomes thicker, more resilient and shiny.
- Wrinkle Treatment: Deep nasolabial grooves and marionette lines soften.
Which Areas is PLLA Applied to?
PLLA is not a treatment that can be applied to the whole face. If it is not applied to the right area (e.g. lips), it may cause nodules. Safe areas according to Medlook protocols:
- Temporal Hollowing
- Cheekbones (Zygoma)
- Cheek Gaps
- Jawline
- Nasolabial Folds
Important Notice: PLLA; lips, under the eyes and in the center of the forehead NOT APPLICABLE. Which treatments are suitable for these areas Who is PLLA Filler Suitable for? you can find in our article.
Implementation Process and Medlook Difference
PLLA application requires more technical expertise than conventional fillers. The product must be prepared and homogenized days before the procedure.
- Planning: Volume losses on your face are determined by 3D analysis.
- Preparation: PLLA powder is mixed with sterile water and lidocaine (painkiller).
- Injection Using the cannula technique, the product is spread in a fan shape into the deeper layers of the skin. The use of cannulas minimizes the risk of bruising.
- Massage (5-5-5 Rule): It is the most critical part of the procedure. The patient should be massaged 5 times a day for 5 minutes 5 times a day for 5 days to avoid clumping of PLLA particles. Compliance with this rule is the key to success.
Difference with Other Regenerative Fillers (PCL vs PLLA)
There are other collagen stimulators on the market, such as PCL (Smart Filler). The difference with PLLA is that the “volumizing” process is slower and more controlled. PCL gives instant fullness, while PLLA requires patience. Find out which one is right for you PLLA or PCL? You can examine the comparison in our article.

Frequently Asked Questions (FAQ)
The swelling seen in the first week goes down and you return to your old self. The real change starts after 4-6 weeks and continues to increase after each session. The full result sits after the 3rd month.
Generally, depending on age and volume loss, 2 or 3 sessions at 4-6 week intervals are recommended. In Medlook, with the "gradual approach", the dose is adjusted according to the need in each session.
No, PLLA does not have a melting enzyme. Therefore, it is very important that it is done in expert hands and in the right dose. However, it is completely metabolized and excreted by the body over time (within 2 years).
This risk existed in the past when product dilution protocols were different. In the current Medlook protocols and if the patient follows the "5-5-5 Massage Rule", the nodule risk is below %1.
