It is a collagen stimulator.
Sculptra is injectable poly-L-lactic acid.
Sculptra vs Subcision
Sculptra: An injectable that does not fill a line directly. It prompts the skin to build its own collagen over several months, so the change is slow, broad, and needs a course of sessions.
Subcision: A needle passed under an indented acne scar to cut the strands holding it down, so the surface can lift. It is aimed at rolling scars specifically, it bruises, and it is almost always combined with something else.
Choose Sculptra if…
Choose for gradual, natural-looking volume over the whole face that lasts years — not for quick or precise filling.
- Broad volume loss, not one line
- You're happy to wait months
- You can do 2–3 sessions
Choose Subcision if…
Choose for rolling acne scars that are tethered down, usually combined with needling, laser or filler.
- Soft, wavy rolling scars
- Scars that improve when you stretch the skin
- You can hide a week or two of bruising
Often combined
Can you have both?
Sculptra is sometimes used after subcision to build collagen under released acne scars.

What is it?
Sculptra
Subcision
What is it?
Results are gradual.
It produces a slow tissue response rather than instant volume.
It cannot be dissolved.
Unlike hyaluronic acid fillers, it is not easily reversed.
Delayed nodules can occur.
Anatomy and previous fillers should be discussed.
It releases scar bands.
Fibrous bands tethering depressed scars are cut beneath the skin.
It suits rolling acne scars.
It is not for every pit, mark or raised scar.
It is minor surgery.
It is performed by a clinician with a needle or blade.
History is reviewed.
Bleeding risk, scarring tendency and isotretinoin use are assessed.

Diagram explanation
PLLA particles are placed: A clinician injects a prepared suspension into selected tissue. A local tissue response develops: The particles stimulate processes involved in collagen formation. Support changes gradually: Collagen buildup can improve selected volume loss and wrinkles.
Schematic illustration. Technique and response vary. This explains a mechanism and does not specify treatment settings.
A scar is tethered below skin: Fibrous bands can pull a rolling scar downward. The bands are released: A clinician passes an instrument beneath the scar. Repair follows the release: The depression may improve as the tissue heals and remodels.

Before your treatment
Sculptra
Subcision
Earlier planning
Not specified
6 months before: After isotretinoin: Most providers wait about 6 months before subcision, though this is debated and some treat sooner.
2–4 weeks before
Before you book: Timing: Not within two weeks of an event.
2 weeks either side: Dental work and shots: Many providers ask for two weeks either side of dental work or a vaccination — both can stir up a delayed reaction around injected material.
2 weeks before: Sun: Keep the area out of the sun and use SPF 30 or higher.
Before you book: Timing: Get active acne under control first, or new scars form beside the treated ones.
The week before
A few days before: Bruising and alcohol: Fish oil, vitamin E and ibuprofen make bruising more likely and are usually stopped a few days ahead, if your doctor agrees.
Actives and supplements: With your prescriber's agreement, stop blood-thinning supplements such as fish oil, vitamin E and ginkgo.

Before you arrive
Clean skin: No makeup.

Arrival & prep
Your face is assessed sitting up, photographed and marked.
Photographs first, then the skin is stretched and lit from the side so tethered scars stand out.
Treatment
Injected through a needle or a blunt cannula in fanned passes across the area, not single deposits, and massaged firmly as they go to spread it evenly.
A face takes 20 to 40 minutes. You feel stinging and pressure with the odd sharper moment; numbing cream handles it.
A tiny entry point is made beside the scar, and the needle or cannula is passed underneath and moved side to side in a fan until the skin releases.
You feel pressure, tugging and a faint crunching as the strands give way. Firm pressure follows to limit bruising, and filler or microneedling may follow. Usually 15 to 45 minutes, and once numb it is pressure, not pain.
Before you leave
Swollen, sometimes noticeably, with small red marks at the entry points and possible bruising.
Swollen, red and firm, with the treated scars looking temporarily better from the swelling.
After your treatment
Sculptra
Subcision
First 24 hours
Days 1 to 3: Bruises at needle sites, tenderness, and swelling that still makes your face look fuller than it will be.
Days 1 to 3: Deep purple bruising appears and spreads downward with gravity, worst around day two or three.
Days 2–7
Days 3 to 14: The fluid drains and your face looks as it did before.
Days 4 to 14: The bruises turn green and yellow, and concealer covers them reasonably well from about day three, once the entry points have sealed.
Weeks 2–4
Weeks 3 to 6: Nothing visible while collagen is laid down.
Weeks 2 to 12: Small firm lumps can be felt as the scar tissue remodels, and most soften on their own.

Cost
Per session
In the US a vial usually runs about $800 to $1,200, and a face session commonly uses one or two vials.
In the US, subcision commonly runs a few hundred dollars per session, and the price rises when filler, microneedling or radiofrequency needling is added — filler is often the larger part of the bill.
Insurance
Insurance does not cover cosmetic use.
Insurance almost never covers subcision for acne scars, because scar treatment for appearance is cosmetic.
Questions
Sculptra
Subcision
Individual Questions
When will I actually see something?
Not for weeks. The fullness on the day is water and it is gone within about two weeks. Real change starts around six to twelve weeks and is judged three to six months after the last session. Take a photo before you start.
Is Sculptra a filler?
Not in the usual sense. A filler is the volume itself and works the day it is injected. Sculptra sets off a repair response and largely disappears, and the volume you end up with is collagen your own skin made.
Can it be dissolved if I do not like it?
No. Hyaluronidase only dissolves hyaluronic acid fillers. For an uneven result the options are waiting, massage, and sometimes steroid injections or minor surgery for a lump. That is the main reason to be selective about who injects it.
What are the lumps people talk about?
Small collections of collagen around the product, usually where it was placed too shallow or spread unevenly. They can appear months later. Many settle on their own; others are treated in the clinic. Even placement and massage are how the risk is lowered.
How many vials will I need?
It depends how much support has been lost, not on age. A face session commonly uses one or two vials, over two to four sessions. A provider who quotes a number before looking at your face is guessing.
What happens when it wears off?
It fades gradually over one to two years and your face returns to the path it was already on. No collapse, no rebound, and no evidence you end up worse than if you had not had it.
How do I know if my scars are the right type?
Stretch the skin either side of the scar, or press gently beside it. If the dip flattens out, it is tethered, and that is the scar subcision treats. Scars with sharp punched-out edges that stay put when you stretch are icepick or boxcar scars and need something else.
How long does the bruising last?
Usually 7 to 14 days. It looks worst around day two or three, then turns green and yellow, and concealer works from about day three. Plan for two clear weeks, not one.
Will one session be enough?
Usually not. Most courses are 2 to 4 sessions, 4 to 8 weeks apart. Some of the immediate improvement is lost as cut strands reattach, and the gain builds over the course.
Do I need filler with it?
Not always, but many providers add it. Filler holds the released space open while new collagen forms, which reduces retethering. Ask what would be used, how much, and what it adds to the cost.
Does it hurt?
The numbing injections sting for a few seconds and are the worst part. After that it is pressure and tugging, not sharp pain. The area is sore for a day or two, like a deep bruise.
Is it safe on deeper skin tones?
Yes, and it is often a good choice, because it uses no heat or light. The thing to manage is a temporary brown mark where the bruising was. Sun protection, limiting the bruising and spacing sessions all help.
