Radiesse
An injectable made of calcium-based microspheres in a gel. It adds volume the day it is placed and then prompts the skin to build collagen. It cannot be dissolved.
Key facts
Treats
Selected volume loss or contour concerns
Recovery
Swelling or bruising for days
Treatment plan
Often 1–2 sessions; later maintenance
Typical cost

What is it?
It is a calcium-based filler.
Radiesse contains calcium hydroxylapatite microspheres in a gel.
It provides structure.
It supports tissue and triggers a later tissue response.
Diluted uses differ.
Hyperdilute use is not the same as volumizing.
Ask about the plan.
The intended use determines the evidence and rescue options.
What it treats
Volume Loss
Restores fullness.
Sagging Skin
Diluted versions improve firmness.
Deep Wrinkles
Fills deep folds.
Wrinkles and Fine Lines
Too heavy for fine lines.
Thin Lips
Not used in the lips.
Treatment areas
Radiesse
Facial volume loss and backs of the hands; product use and dilution depend on the plan.

Skin tones
Lighter skin
Low risk
Bruising fades in a week.
Medium skin
Low risk
Not a pigment-based treatment.
Deeper skin
Low risk
Bruising may leave brief dark marks.
How it works
Diagram explanation
The material is placed: A clinician injects calcium hydroxylapatite in a gel carrier. The gel provides initial support: Early correction depends on formulation and placement. Collagen response develops: Tissue remodeling contributes as the gel carrier is absorbed.
Schematic illustration. Technique and response vary. This explains a mechanism and does not specify treatment settings.
Types
Radiesse can be used full strength to add volume or diluted to improve skin quality.
Before your treatment
2–4 weeks before
2 weeks before: Events and dental: Do not book within two weeks of an event; bruising and swelling are normal, and swelling makes the early result look bigger.
Before you book: Infections and scans: Reschedule if there is an active infection, cold sore or inflamed cyst in the area.
The week before
A few days before: Blood thinners: Ask the prescribing doctor before pausing one.
The day before: Alcohol: None.
Day of treatment
Arrival & prep
The area is assessed sitting up, photographed, and the injection points marked.
Treatment
The product goes in deep, often onto or just above bone, through a needle or a blunt cannula, then each area is molded smooth.
A face takes about 20 to 40 minutes; hands and diluted treatments are quicker. You feel pressure and a deep ache more than sharp pain, with stinging at the entry points.
Before you leave
Swollen, with small red marks at the entry points and possible bruising.
After your treatment
First 24 hours
Days 1 to 3: Bruises appear at needle sites and the area feels tender and firm — swelling and product, not a lump.
Days 2–7
Days 4 to 14: Swelling drains and the area softens.
Weeks 2–4
Weeks 2 to 12: The gel carrier is absorbed while new collagen replaces it.
Time to results
Immediately
How long results last
About 12–18 months
Risks
Most reactions are injection-site effects that settle within a week or two
swelling, bruising, redness and firmness. The risks specific to this product come from its firmness and the fact that it cannot be dissolved.
A lump you can feel
Nodules are more likely in mobile areas and where product sat too shallow. Some settle; others need steroid injection, massage under local anesthetic, or occasionally minor surgery. Raise it early.
A pale or white line under the skin
Product too close to the surface can show through on thin skin. Report it rather than waiting it out.
Spreading redness or tenderness
This can mean infection around the injected material and usually needs antibiotics.
A new lump months later
A delayed inflammatory reaction is uncommon but recognized, and treatable.
Unevenness between the two sides
Say so at the review appointment, while a plan can still be made.
Cost
Typical cost
Per syringe, similar to HA filler
Pricing
In the US a syringe usually runs about $700 to $1,200.
Insurance
Insurance does not cover cosmetic use.
Alternatives
Hyaluronic acid fillers
Softer, usable in lips and under the eyes, and reversible with hyaluronidase. Radiesse is firmer and lasts longer in some areas, but a poor result cannot be undone.
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.
Fat transfer
Surgical, done once, potentially long-lasting, with real downtime and a variable amount of fat surviving.
Energy tightening devices
Radiofrequency and ultrasound firm the skin rather than support it. Useful when the problem is laxity rather than lost volume, with modest results over several sessions.
Skin boosters and microneedling
Similar aims for skin quality on the neck, chest and hands, with different downtime and different costs.
Topical retinoid
The one home product with solid evidence for building collagen. It improves skin quality and fine lines. It does not restore support or shape a jawline.
Daily sunscreen
Prevents further collagen loss, which is the thing this treatment is compensating for.
Firming creams marketed for the jawline or neck
Some improve surface texture and hydration. None move the underlying structure.
Questions
Is Radiesse a filler or a collagen stimulator?
Both. The gel gives volume the day it is injected, and the calcium particles prompt new collagen over the following months as the gel is absorbed.
Can Radiesse be dissolved?
No. Hyaluronidase dissolves hyaluronic acid only, and there is no equivalent here. A result you dislike has to be managed with time, massage, steroid injection or, rarely, minor surgery. Understand that before you agree to it.
How long does it last?
Usually about 12 to 18 months in the face, then a gradual decline. Some people keep a little extra firmness from the collagen that formed, but that is a bonus, not the plan.
Why can it not go in my lips?
It is firm and lips move constantly. That gives a high rate of lumps, and a lump in a lip is visible and hard to treat in a product that cannot be dissolved. Hyaluronic acid is used there instead.
Will it show up on an X-ray or a dental scan?
Yes, on X-rays and CT scans, which is harmless. Tell your dentist and any radiologist so a bright patch is not investigated as something else.
Will it feel hard?
It should not, once swelling settles. Placed deep, it feels like your own tissue. Firmness you can feel through the skin after a few weeks usually means it sat too shallow — worth reporting.
