Sculptra
How Sculptra works. The PLLA microparticles add almost no volume themselves — they prompt your own collagen to build up gradually over months.

Sculptra vs Radiesse
The big difference is timing. Sculptra shows nothing on the day and builds collagen over months, across a course of two to four visits. Radiesse gives some lift straight away, then builds collagen too. Neither one can be dissolved, so neither can be undone.
At a glance
| The difference | Sculptra | Radiesse |
|---|---|---|
| What it is made of | Poly-L-lactic acid | Calcium hydroxylapatite |
| How long until you see the result | Two to three months | Now, then a dip, then a build |
| What it is used for | Broad areas | Structure and lines |
| Cost | Priced per session, and it is a course | Priced per session, usually fewer of them |
Radiesse
How Radiesse works. The CaHA microspheres give lift straight away, then act as a scaffold while new collagen forms around them.
Side by side
The differences that matter
What it is made of
Sculptra
Poly-L-lactic acid
The same material used in dissolvable stitches. It is suspended in liquid and injected as a fine spread.
Radiesse
Calcium hydroxylapatite
Tiny calcium microspheres, the same mineral found in bone, suspended in a gel.
How it works, illustrated
Sculptra
Radiesse
Do you see anything on the day
Sculptra
No
There is swelling from the fluid. It settles within a few days. Then you look the same as before while collagen builds. Looking unchanged a week later is what is supposed to happen.
Radiesse
Yes
The gel gives volume right away. That fades over a few months as the gel absorbs, and collagen replaces it.
How long until you see the result
Sculptra
Two to three months
Sometimes longer. It is a slow build.
Radiesse
Now, then a dip, then a build
You look fuller straight away, less full at around two months, then better again.
How many sessions
Sculptra
Usually two to four
Spaced about a month apart. It is a course, not one appointment.
Radiesse
Often one
Sometimes a touch-up later.
How long it lasts
Sculptra
About two years
Radiesse
About one year
What it is used for
Sculptra
Broad areas
Hollow cheeks, temples, overall facial thinning. Also used on the body, such as crepey skin above the knees.
Radiesse
Structure and lines
Jawline, chin, cheekbones, backs of the hands. It has more lift, so it suits a defined edge.
Can it be reversed
Sculptra
No
Radiesse
No
Main risk to know
Sculptra
Small lumps under the skin
Uncommon, and mostly preventable. That is why the product is spread widely rather than placed in one spot. It is also why massage afterwards is part of the instructions.
Radiesse
Not for the lips
Radiesse has a higher rate of lumps in lip tissue, so it is not used there.

Sculptra
Radiesse
Moderate evidence. The other common biostimulator. It adds volume the same day as well as building collagen, and typically lasts about 12 to 18 months rather than two years. Also not reversible.
Radiesse
Sculptra
Moderate to strong evidence. A pure collagen stimulator with no same-day change, given as a course, and typically lasting around two years. Broader and softer in effect, and also not reversible.
Aftercare
Sculptra
Massage
Many injectors ask for five minutes, five times a day, for five days.
Radiesse
Less involved
Usual filler aftercare. Avoid heavy exercise and heat for a day or two.
Cost
Sculptra
Priced per session, and it is a course
Ask for the cost of the whole plan.
Radiesse
Priced per session, usually fewer of them
Often one appointment, so the total is easier to pin down.
Who each suits
Sculptra
- Best for — Overall volume loss across the face, and someone happy to wait.
- The mindset — You want gradual change nobody can point to.
Radiesse
- Best for — Jawline and chin definition, and hands.
- The mindset — You want to see something now, and accept it cannot be undone.
What neither one does
Conditions treated
Sculptra
Wrinkles and Fine Lines
A collagen-stimulating injectable given as a course, usually three sessions. Nothing looks different straight away; volume builds gradually over several months and lasts around two years. It suits overall thinning and flatness rather than a single line, and it cannot be dissolved, so it is a slower and less reversible decision than filler.
Radiesse
Wrinkles and Fine Lines
A thicker injectable that both fills immediately and stimulates collagen over the following months, used mainly along the jaw and in the cheeks and hands. It is firmer than hyaluronic acid filler, so it is not used in delicate areas like under the eyes, and it cannot be dissolved.
Common questions
Questions Patients Ask
Radiesse vs Sculptra — what is the difference?
Both are biostimulators that prompt your own collagen rather than filling a space, and neither can be dissolved. Radiesse gives some lift on the day and then builds collagen. Sculptra gives nothing on the day and builds more collagen gradually over months. Radiesse is the quicker one; Sculptra is the more gradual one.
Are these fillers?
Not in the usual sense. They are biostimulators. A standard filler like Juvéderm or Restylane is hyaluronic acid gel that fills a space and can be dissolved. Neither of these can be dissolved.
Which lasts longer?
Sculptra, at roughly two years versus about one. Longer is only an advantage if you like the result, since neither can be reversed.
Can Sculptra or Radiesse be dissolved if I don't like it?
No. This is the most important difference between these and hyaluronic acid fillers. If you are new to injectables, starting with something dissolvable is the lower-risk way to learn what you like.
Why can't I see anything after my Sculptra appointment?
That is expected. The swelling right after is from the liquid it is suspended in, and it settles within days. The actual result builds over two to three months as collagen forms.
How many sessions will I need?
Sculptra is usually a course of two to four sessions about a month apart. Radiesse is often a single session with a possible touch-up.
Which one is better for the jawline?
Radiesse is more commonly used there. It has more lift, which suits a defined edge. Sculptra suits broad volume loss across cheeks and temples better.
Can Radiesse be used in lips?
No. It has a higher rate of lumps in lip tissue and is not used there.
Do these tighten loose skin?
No. If skin laxity is your main concern, these will disappoint you. That is a question for energy-based devices or surgery.
What is the serious risk?
The rare one shared by all injectables: product entering a blood vessel. Call your injector the same day if the skin turns white, blotchy or dusky, if pain is getting worse, or if your vision changes at all. This is why who injects you matters more than which product they use.
