Biostimulators (Sculptra, Radiesse, Ellansé): what they do, what they cost and what to ask before you book
Biostimulators promise a fresher, better supported face without an obvious filled look, and the products in this group behave very differently from one another. Which one suits a patient depends on the area, how long the result should last and whether the patient will do the aftercare.
In The Ageless Blueprint, Dr Leah rates five biostimulator products out of 10, with a separate rating for Ellansé on the backs of the hands, and explains why each earns its score. This page sets out the facts that apply to all of them.What biostimulators are
Biostimulators are injectable products that prompt the skin to produce new collagen, so that tissue quality and support improve gradually over several months. Some also contain a carrier gel that gives an immediate filling effect while the collagen response develops. The best-known products in the UK are Sculptra (poly-L-lactic acid), Radiesse (calcium hydroxylapatite microspheres in a gel), Ellansé (polycaprolactone microspheres in a carboxymethylcellulose gel), JULÄINE (a newer poly-L-lactic acid product with uniform microspheres) and HArmonyCa (a hybrid of hyaluronic acid and calcium hydroxylapatite).
Sculptra was first approved in Europe in 1999, so the category is older than its current popularity suggests. Used conventionally, Radiesse and Ellansé give immediate structure; diluted, Radiesse shifts towards a broader improvement in skin quality. Beyond the face, biostimulators are used off-label on the backs of the hands and on fine, crepey skin of the upper and middle neck, where a course may be needed and the tightening is usually modest.
Generally used for
- Volume loss in the temples, cheeks and lower face, including after marked weight loss
- Overall skin quality and firmness where an obvious filled look is unwanted
- Longer-lasting support for patients who prefer less frequent maintenance
What the guide covers that this page does not
- Dr Leah’s rating out of 10 for each of the five products, and why
- Which product Dr Leah uses for the backs of the hands, and the results Dr Leah has seen
- The areas Dr Leah will not treat with Sculptra, and the product Dr Leah uses there instead
- How Dr Leah approaches crepey neck skin with hyperdiluted products
What to expect
| Results | The collagen-related change is gradual and may take three to six months to develop. Products with a carrier gel give an earlier filling effect. Response varies between people, so both undertreatment and overtreatment are possible. |
|---|---|
| How long it lasts | Manufacturers describe up to two years for Sculptra and Radiesse in studied facial areas, and approximately two to four years for Ellansé. Off-label neck results should not be assumed to last as long. |
| Appointment and downtime | Many plans need two or three appointments rather than one. Sculptra requires rigorous home massage after treatment, commonly five minutes, five times a day, for five days. Bruising and swelling are possible with any injectable. |
| What can go wrong | Lumps are the characteristic risk: palpable collections, inflammatory nodules or, less commonly, granulomas. The collagen effect cannot be dissolved, so correction of an unwanted result may be limited. Infection and rare vascular complications apply as with any injection. Previous biostimulator treatment should be declared to a surgeon before any later facelift. |
| Cost | Typical UK prices: Sculptra £550 to £950 per vial, JULÄINE £800 to £1,200 per vial, Ellansé £450 to £750 per syringe for the face and £900 to £1,500 for two syringes on the hands, HArmonyCa £500 to £800 per syringe. A full course usually costs more than a single hyaluronic acid filler treatment. |
Five things to ask before you book
- Which product are you proposing, and why that one rather than a hyaluronic acid filler for my concern?
- How many vials or syringes will I need across the course, and what is the total cost?
- What aftercare will I have to do at home, and for how long? Sculptra and JULÄINE differ a great deal here.
- What happens if I develop a lump or nodule, given that the product cannot be dissolved?
- Is the area you are suggesting, such as my neck or hands, within the product’s licensed use or off-label?
Dr Leah’s verdict is in the guide
Chapter 3 of The Ageless Blueprint rates biostimulators as a group and then each of the five products out of 10, with a separate rating for Ellansé on the backs of the hands. It explains which product Dr Leah considers the best value for overall facial support, which Dr Leah is selective about because its effect lasts so long, where Dr Leah uses each one and where Dr Leah will not, and how accordion lines on the cheeks and crepey neck skin are approached. Nine pages, with illustrations.

Common questions
Not in the usual sense. Sculptra is poly-L-lactic acid, which prompts the skin to make its own collagen over months. It gives little immediate volume, unlike a hyaluronic acid filler, and the result cannot be dissolved. Dr Leah’s rating for it is in chapter 3.
Manufacturers describe Sculptra and Radiesse results lasting up to two years in studied areas, and Ellansé formulations as lasting approximately two to four years. Duration varies between people and between treatment areas.
No. The new collagen cannot be dissolved, which is the main difference from hyaluronic acid filler. HArmonyCa contains a hyaluronic acid component that can be dissolved, but that does not reverse its calcium hydroxylapatite or the collagen it stimulates.
