Radiesse vs Botox
Botox Cosmetic relaxes the muscles that make lines when you move. It is used for frown lines, lines at the outer corner of the eye, forehead lines and neck cords, and it wears off over months. Radiesse is a calcium-based filler that adds volume where the face has lost it. It builds out a jawline or the back of the hands and prompts your body to make collagen — and it cannot be dissolved.

Botox
An injectable treatment being placed in the face. A neurotoxin is given with a very fine needle in small amounts, and each spot takes only a few seconds.
Side by side
The differences that matter
What you actually do
Radiesse
An injection that adds volume
Radiesse is calcium hydroxylapatite, a mineral ground into tiny spheres and mixed into a gel. It is injected deep, under the skin or onto the bone beneath it.
Botox
An injection that relaxes muscle
Botox Cosmetic is a prescription botulinum toxin. It is given as several small shots into the muscles that make the line. How many shots you need depends on how many areas are treated.
How it works, illustrated
Radiesse
Conditions treated
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.
Botox
Hyperhidrosis
A grid of small injections that block the nerve signal reaching the sweat glands in that patch of skin. It starts working within a few days to a week and lasts several months before it needs repeating. Underarm injections are well tolerated; palms and soles hurt more and are usually done with numbing, and palm injections can cause temporary weakness of grip. It is an approved medical treatment for severe underarm sweating, not a cosmetic one, and insurance often covers it once antiperspirants have been tried and documented.
1 / 3→
Rosacea
Very small amounts injected into the surface of the skin, not the muscle, to reduce flushing and background redness. Early studies are encouraging and dermatologists do use it for stubborn flushing. It is off-label for rosacea, it is not usually covered, and it wears off in a few months.
←2 / 3→
Wrinkles and Fine Lines
The reliable treatment for lines caused by movement — frown lines, forehead lines and crow's feet. It relaxes the muscle that folds the crease, so the line softens over about two weeks and returns as the effect wears off at three to four months. It does nothing for lines that are already there at rest, and nothing for sagging.
←3 / 3
What you can expect to see
Radiesse
Volume straight away, then collagen
The gel gives volume right away. Your body absorbs the gel over the first two to three months. The mineral spheres stay behind, and your body builds collagen around them before breaking them down.
Botox
Lines that stop forming
The muscle stops contracting for a while, so the skin over it stops folding. Nothing is added underneath.
What it will not do
Radiesse
It will not lift lax skin
Filler does not lift skin that has become lax, so it does not treat jowls. The label also says it has not been shown to be safe or effective in the lips, and nodules have been reported there.
Botox
It adds no volume
It relaxes muscle and nothing else. In the neck it treats the cords that stand out when you tense, not the skin quality around them.

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.
If you want it undone
Radiesse
It cannot be dissolved
Hyaluronidase is the enzyme that dissolves hyaluronic acid fillers. Radiesse has none in it, so the enzyme has nothing to act on. The options are time, saline broken up through a cannula, steroid shots and, rarely, surgery.
Botox
No antidote, but it wears off
There is no reversal agent for botulinum toxin either. It fades on its own over months and takes nothing with it.
How long it lasts
Radiesse
Months to a few years, measured
In one trial, 40% of treated folds were still graded improved at 30 months or more after the last treatment. That means 60% were not. The FDA's consumer page puts calcium hydroxylapatite at about 18 months.
Botox
The label puts no number on it
The label calls the improvement temporary. It gives no duration figure at all.
The at-home or drugstore version
Radiesse
There is no home filler
Nothing sold over the counter puts a gel under your skin. Lip plumpers mildly irritate the lip, so it swells for a few hours. That is not the same thing.
Botox
There is no Botox in a bottle
The peptide serums sold under that name sit on the surface. The muscle is several millimetres down, and a cream does not get there.
Who tends to be happy with it
Radiesse
- Best for — Someone who wants structural support along the jawline or in the back of the hands.
- The mindset — A firmer result that lasts longer. But it is a one-way door.
Botox
- Best for — Someone whose complaint is a line that only appears with movement, or neck cords that stand out when they tense.
- The mindset — Reversible by default, because it fades.
Why "reversible" does not apply here
Botox
Botox Cosmetic has no antidote either. The difference is that it fades in months and takes nothing with it.
The fine print
Radiesse
Radiesse is FDA approved as a Class III device. The 2006 approval covers "subdermal implantation for the correction of moderate to severe facial wrinkles and folds, such as nasolabial folds". Hand augmentation was added in 2015, jawline contour for Radiesse (+) Lidocaine in 2021, and wrinkles on the chest at a 1:2 dilution with saline in 2026. It is also approved for facial fat loss in HIV. It is not approved for jowls, marionette lines or the temples by name.
Radiesse composition. Calcium hydroxylapatite spheres 25 to 45 microns across, in a gel of sterile water, glycerin and carboxymethylcellulose.
The Radiesse label sets a limit on how long it has been studied. It states only that safety beyond 3 years in the face and 2 years in the hand has not been investigated.
Botox
Botox Cosmetic is onabotulinumtoxinA, a botulinum toxin type A. It is approved for four areas: frown lines between the brows in 2002, lines at the outer corner of the eye in 2013, forehead lines in 2017, and the neck cords called platysma bands on 18 October 2024.
Label doses are given in Botox Cosmetic Units only. They are 20 Units, 24 Units, 40 Units in total for the forehead together with the frown lines, and 26, 31 or 36 Units for the neck cords depending on severity. These units do not convert to any other brand.

Ask for the complete Botox treatment price for the planned muscles and dose. Its per-unit price cannot be compared directly with a filler syringe price.
Common questions
Questions Patients Ask
Can Radiesse be dissolved?
No. Hyaluronidase only breaks down hyaluronic acid, and Radiesse contains none — it is calcium hydroxylapatite microspheres in a carboxymethylcellulose gel. There is no approved reversal agent, and the current labelling names none.
What about sodium thiosulfate?
It is not established. A 12-sample cadaveric porcine study and some case reports support it, but the largest preclinical study, run by the manufacturer, found no degradation of calcium hydroxylapatite in the laboratory or in live animals and did observe necrosis and haemorrhage. A separate cadaveric study found CaHA still present in facial artery segments after 24 hours regardless of concentration.
Is Radiesse permanent, then?
No — and that is a different question from whether it is reversible. The microspheres break down into calcium and phosphate that the body handles normally. What you cannot do is make that happen on demand. The label says only that safety beyond 3 years in the face and 2 years in the hand has not been investigated.
Which one is better for the jawline?
They do different things. Radiesse (+) Lidocaine has been approved since 2021 to improve moderate to severe loss of jawline contour, and 75.6% of treated people responded at week 12 against 8.8% of controls. Botox Cosmetic has no jawline indication; its neck approval is for platysma bands. Neither treats jowls, and no filler lifts lax skin.
Can Radiesse be used in marionette lines or the temples?
Marionette lines are not named in any Radiesse approval, though the general wording "facial wrinkles and folds, such as nasolabial folds" is an example rather than a limit and plausibly covers them — with no trial evidence specific to that area. Radiesse is not approved for the temples. Off-label use is legal and routine, but it means the trial figures do not apply there.
Which lasts longer?
There is no answer from published evidence, because no trial has compared them and they are not measuring the same thing. Radiesse's longest measurement found 40% of nasolabial folds still graded "improved" or better at 30 months or more after the last treatment - so 60% were not. The FDA's consumer page puts calcium hydroxylapatite at approximately 18 months. The Botox Cosmetic label gives no duration figure at all and calls the improvement temporary.
Is Radiesse riskier than a dissolvable filler?
The rare emergency — filler entering a blood vessel — applies to both, but it cannot be treated with hyaluronidase when the product is calcium hydroxylapatite. That is a real difference in what can be done in an emergency, and it is worth weighing before choosing a product that is not dissolvable.
Should I have Radiesse in my lips?
The Radiesse labelling states that safety and effectiveness for use in the lips has not been established, and notes published reports of nodules after injection into the lips. Consensus reviews advise avoiding calcium hydroxylapatite in highly mobile areas such as the lips and in the area around the eye.
