PLLA filler explained: how Sculptra builds volume, and who it suits
PLLA filler doesn't fill, it makes your skin build collagen. How Sculptra differs from HA filler, what happens week by week, and how we avoid nodules.

What is PLLA filler, and is it really a filler?
PLLA filler is the name people search for Sculptra, an injectable made of poly-L-lactic acid (PLLA). The name is a little misleading: PLLA does not fill a hollow the way a gel does. It stimulates the fibroblasts around it so your skin makes its own collagen, and the volume arrives gradually.
I'm Hyo Seop Ryu, a board-certified dermatologist and chief director at WELLS in Apgujeong, and formerly an assistant professor at Seoul National University Bundang Hospital.
All three of our chief directors, myself included, completed Handok's Sculptra hands-on training, and WELLS guarantees every Sculptra vial is genuine.
PLLA is a plant-derived synthetic polymer. Injected as a fine powder suspended in liquid, it acts as a scaffold in the skin and then breaks down into water and carbon dioxide, while the collagen it prompted stays. Sculptra holds both US FDA and Korean MFDS approval.
The analogy I use in consultation: hyaluronic acid filler is buying flowers and putting them in a vase. Sculptra is planting a seed and letting the flower grow.
PLLA filler vs hyaluronic acid filler: what's the difference?
Both improve volume, but they solve different problems. HA filler is strong at shaping a specific contour; PLLA is strong at restoring the overall thickness and volume of the skin.
| Hyaluronic acid filler | PLLA (Sculptra) | |
|---|---|---|
| How it works | A gel physically fills the space | Stimulates your own collagen |
| When you see it | Immediately after injection | Gradually, over the following weeks and months |
| How long it generally lasts | Usually about 6 months to 1 year | Collagen formed can last about 2 years or more |
| Best at | Defining a contour: chin, forehead, folds | Broad, gradual volume loss across the face |
| Sessions | Often one | Usually about 3, a month apart |
Because PLLA volume is your own tissue, it breaks down more slowly than an external substance, and it moves with your expressions. When a whole face has slowly deflated and looks tired, I often find Sculptra the more natural choice. When one area needs a clear shape, such as a forehead filler or the chin tip, our dermal fillers are usually the better tool.
What happens after a PLLA injection, week by week
Right after treatment the area looks fuller, but that is the injection fluid, not the result. Within about a week the fluid is absorbed and the face looks much as it did before, which is exactly when people panic unnecessarily.
From there the PLLA slowly breaks down and collagen production begins, and from about four to six weeks your own tissue starts to fill in. Because the final volume shows at around three to six months, the dermatologist has to predict it at the first session, which is why this treatment needs experience with facial structure.
We generally recommend about 3 sessions, one month apart, building collagen step by step rather than all at once. That pacing is also what keeps the result from looking done.
Why cc is the wrong question
Patients often ask how many cc they will get. With Sculptra, the PLLA content matters more than the volume of liquid: dilute a vial more and you inject more cc at a lower concentration, like adding water to coffee. What counts is how the PLLA in one vial is used, where, and by what criteria.
Filler in temples to lift eyes, filler in cheeks to lift jowls: where PLLA works
PLLA works best where fat loss is noticeable: the temples, the front cheeks and the upper part of the nasolabial folds. When ageing hollows the side cheek below the cheekbone, it can also soften that edge so the face shape reads smoother.
The searches for filler in cheeks to lift jowls or filler in temples to lift eyes point at a real idea, with a catch. Filling the area that sags tends to look heavy. Our Sculptra Lifting protocol instead maps the face's lifting vectors and places Sculptra at the temples and upper face, supporting tissue upward.
| Direct filling | Sculptra Lifting | |
|---|---|---|
| Where it's injected | Into the sagging area | Into the upper-face support points |
| How it lifts | Adds volume where it sags | Supports tissue upward along natural vectors |
| Result | Can look heavy | Contour and dimension restored naturally |
Sculptra Lifting is listed at ₩1,320,000 (VAT excluded) per session. It suits sagging cheeks and mid-face, a less-defined jawline, and hollow temples with a flattened upper face.
Wondering whether your face needs PLLA, HA filler or a lift? Send a front and side photo with your dates, and a dermatologist will suggest where to start.
Send a photo for a PLLA planWhere I'm cautious with PLLA filler
Mobile areas such as around the mouth and eyes carry a higher risk of nodules, so dose and depth there have to be adjusted extremely finely. Under the eyes, where skin is at its thinnest, particle-based collagen stimulators can rarely leave a palpable nodule, and I take a very conservative approach.
PLLA also isn't a quick fix. If you need a visible change for an event next week, it is the wrong treatment, and I'll say so at consultation.
And if your worry is looking overfilled, gradual collagen is one answer but not the only one. Our Korean filler guide covers pillow face and when filler is the wrong tool, and bad cheek fillers explains why filling sagging cheeks backfires.
How we prevent nodules with PLLA
A nodule is where injected particles clump in one spot and feel hard. It is the main thing to watch with Sculptra, and it is largely preventable with technique and aftercare.
- Proper hydration time. We never mix the powder hastily just before treatment; it is given the full time to disperse evenly.
- The right depth, by micro-cannula. Too shallow raises nodule risk and too deep weakens the effect.
- Dose adjusted by area, especially in mobile zones.
- Reassessment every session. Where the treatment calls for it, 3D analysis shows volume loss and asymmetry the eye misses, and we adjust the amount and areas each time.
Your part is the 5-5-5 rule: massage the treated area for 5 minutes, 5 times a day, for 5 days after each session. We show you exactly where before you leave, because skipping it makes clumping more likely.

PLLA filler price, combinations and planning a visit
The price of a standard Sculptra treatment is confirmed at consultation; Sculptra Lifting is listed at ₩1,320,000 (VAT excluded) per session. The dermatologist tells you at consultation whether one session is enough or a course is needed.
Sculptra combined with a thread lift gives a stronger and longer-lasting result. Lifting devices such as Collagen Booster Thermage FLX act on a different layer, so combinations are common, and the order and timing are planned at consultation.

Sessions a month apart need planning if you live abroad. Send your concern and dates on WhatsApp and we reply in English; the consultation at the clinic is in English too, a five-minute walk from Exit 3 of Apgujeong Station.

Is PLLA filler the same as Sculptra?
Yes. PLLA filler usually means Sculptra, a poly-L-lactic acid injectable that stimulates your own collagen rather than filling space with a gel.
How long does PLLA filler last?
The collagen formed after a Sculptra course can last about 2 years or more, while hyaluronic acid filler usually lasts about 6 months to 1 year. Results vary with how quickly each person ages.
How many PLLA sessions will I need?
About 3 sessions, one month apart, are generally recommended. The dermatologist confirms the number for your face at consultation.
Why does the volume disappear after a week?
The early fullness is injection fluid, which is absorbed in about a week. Your own tissue starts filling in from about four to six weeks as collagen forms.
How much is Sculptra at WELLS?
Standard Sculptra is priced at consultation. Sculptra Lifting, the WELLS protocol at the temples and upper face, is listed at ₩1,320,000 (VAT excluded) per session.
Results and recovery vary by individual. Every treatment carries possible side effects, which are explained at the consultation. Prices are in Korean won, excluding 10% VAT, and confirmed at your consultation. This article is general information from the clinic, not a diagnosis.
