In brief
Bio-stimulators, such as Sculptra, Radiesse and Ellansé, are injectables intended to prompt the skin's own collagen rather than add volume on the day, as a dermal filler does. Any change is gradual, and unlike a hyaluronic acid filler they cannot be dissolved, so a doctor plans the course across months after assessment.

What is a bio-stimulator?
A bio-stimulator is a type of injectable treatment given by a doctor that is intended to support the skin's own collagen framework, rather than to add immediate volume the way a conventional dermal filler does.
How does a bio-stimulator work with your own collagen?
Bio-stimulators are delivered by injection into targeted layers of the skin. The formulation acts as a scaffold within the tissue, and the body is intended to respond by gradually renewing its own supporting structures around it.
Because the response builds gradually and varies between people, review appointments are how change is judged.
What Bio-stimulator is used for at Kaiteki
Gradual collagen rebuilding over months
Change is deliberately slow, which some people prefer and others find frustrating.
Sculptra, Radiesse or Ellansé: which material, and why
Each product uses a different base material, which changes how it behaves and how long it takes to resorb.
Sculptra
Poly-L-lactic acid · Galderma
Reconstituted before use and intended to act as a gradual collagen stimulus over a course of sessions. The reconstituting fluid is absorbed within days, so early appearance is not the treatment effect.
About SculptraRadiesse
Calcium hydroxylapatite · Merz
Support from the gel carrier when it is placed, then a collagen and elastin response as the microspheres are resorbed, with manufacturer-cleared use on the hands and décolletage as well as the face.
About RadiesseEllansé
Polycaprolactone · Sinclair
Support from the carrier gel when it is placed, plus a collagen response as the PCL microspheres are resorbed, supplied in variants that differ in how long the microspheres take to clear.
About EllanséDeusaderm
Collagen-based
A collagen-based injectable intended to support skin quality, structure and elasticity.

What a session involves
Consultation and assessment
The doctor assesses your skin, confirms suitability, discusses the realistic time course and selects the product.
Preparation
The skin is cleansed and prepared, and topical or local anaesthetic is used for comfort.
The injections
The doctor injects the assessed areas.
Afterwards
The doctor may massage the treated area and explains aftercare, including any massage to do at home.
After a session
At the injection sites
Mild swelling, redness or tenderness may occur and usually settles within a few days. Bruising can occasionally take longer to fade.The first days
Avoid pressure or vigorous facial treatments on the area for a short period, and follow any massage instructions given.
Follow the massage and aftercare instructions you are given for your product.
Risks, side effects, and what Bio-stimulator cannot do
Common and temporary
Temporary redness, swelling, bruising or tenderness at the injection sites.Less common
Delayed-onset lumps or nodules have been reported with collagen-stimulating products, sometimes months after treatment, and rare but serious vascular complications are recognised for facial injectables in general.What it cannot do
- It does not add volume on the day: change develops gradually over months.
- It cannot be dissolved the way a hyaluronic acid filler can.
- It is not permanent. The material is resorbed, and your own tissue continues to age.
Raise any delayed lump, swelling or skin change with the clinic straight away, even months after treatment.
What affects the number of sessions, and the cost
Kaiteki does not quote prices online, because the product and the plan are decided at consultation. What moves it:
- Which product the doctor selects for your assessment.
- The area being addressed, and how much structural support has been lost.
- The number of sessions in the course.
- Whether periodic maintenance is part of the plan.
Devices used at Kaiteki
Which platform is used depends on your individual assessment.
Common questions
Is a bio-stimulator the same as a dermal filler?
No. A dermal filler adds volume directly and, if hyaluronic acid, can be dissolved. A bio-stimulator prompts your own collagen gradually and cannot be dissolved.
Are bio-stimulator treatments suitable for sensitive skin?
Sometimes, but it cannot be assumed. Active inflammation, keloid scarring and autoimmune conditions are the factors the doctor checks first.
Is there any downtime?
Usually minimal: mild swelling, redness or tenderness at the injection sites that settles within a few days. Bruising can take longer.
How many sessions will I need?
Usually a short course spaced several weeks apart, sometimes with periodic maintenance afterwards.
