What RADIESSE is and how it differs from hyaluronic acid
RADIESSE is a dermal filler made of tiny calcium hydroxylapatite microspheres, 25 to 45 microns across, suspended in a water-based gel. Calcium hydroxylapatite is a mineral found naturally in bone and teeth. The version used for the jawline, RADIESSE (+), has lidocaine mixed in for comfort.
Two features set it apart from the hyaluronic acid gels most people picture when they think of filler:
- It is firmer. It holds a sharp edge along bone instead of spreading, which is what a defined jaw angle needs.
- It works twice. The gel gives immediate volume, and the microspheres then act as a scaffold for new collagen. An evidence-based review of calcium hydroxylapatite describes immediate volume replacement for up to 12 months followed by longer-term correction from that collagen response, with some nasolabial fold studies showing results at 30 months or more.
The FDA first approved RADIESSE in 2006 for moderate to severe facial wrinkles and folds, such as the lines beside the nose and mouth. In September 2021 it approved RADIESSE (+) for deep injection to improve moderate to severe loss of jawline contour in adults over 21.
Why it suits a man’s jawline
A strong male jaw is mostly about edges: a crisp angle below the ear, a straight line along the bone and a defined border where the jaw meets the neck. RADIESSE is placed deep, just above the bone or under the skin, to rebuild those edges.
In the FDA jawline study, 75.6% of treated patients improved by at least one grade on a jawline scale at 12 weeks, against 8.8% of untreated controls. Among the 21 men in the treated group the rate was 66.7%. Of those who responded, 67.3% kept the improvement at 48 weeks. The median amount at the first session was 1.8 mL per side, with smaller touch-ups four weeks later where needed.

The trade-off: it cannot be dissolved
This is the most important thing to understand before choosing RADIESSE. Hyaluronic acid can be broken down within days by an enzyme called hyaluronidase if you dislike the result or a complication occurs. RADIESSE cannot. The same review classes it as an “adjustable” filler, while hyaluronic acid is fully reversible, and advises against it in very mobile areas such as the lips and in unforgiving areas such as around the eyes.
In practice that means:
- Conservative amounts first, with a touch-up rather than overfilling. The RADIESSE (+) instructions specifically warn against overcorrecting, because the area keeps improving over several weeks.
- RADIESSE is kept to deep structural areas: jaw, deep folds, sometimes cheekbones.
- Men who want a trial run often start with hyaluronic acid. Our JUVÉDERM versus RADIESSE comparison and the page on whether filler can be dissolved help with that decision.
Who it suits, and who should not use it
RADIESSE tends to suit men who want firm jaw definition, have deep folds in heavier skin, or have had hyaluronic acid before and want structure that lasts longer.
It is not for men with severe allergies or a history of anaphylaxis, allergy to lidocaine, a bleeding disorder or an active infection near the area. Its label adds that safety has not been studied in people prone to keloids or raised scars. It is not used in the lips or under the eyes. If you are not sure whether you want the change, start with something reversible.
How the clinic decides, and the visit step by step
Your nurse injector looks at the jaw from the front, side and below, feels the bone and checks how much skin laxity there is. Loose skin under the jaw is not fixed by filler, and adding firm product there can look heavy. If several areas need work, RADIESSE may be one part of a staged plan described on our masculine facial contouring page.
On treatment day:
- Photos, consent and a marked plan of entry points along the jaw.
- Cleansing and optional topical numbing; the lidocaine in RADIESSE (+) adds comfort.
- Deep placement along the bone with a needle or cannula, in small amounts.
- Molding and a symmetry check with you sitting up.
- Written aftercare and a follow-up date about four weeks out.
What to expect, side effects and safety
| Time | What is typical |
|---|---|
| Same day | Immediate definition; tenderness and swelling |
| First week | Bruising, redness and swelling settle, usually within 7 days per the label |
| Weeks 4 to 12 | Collagen response builds; touch-up visit if needed |
| About a year | In the FDA study, two-thirds of responders still held the result at 48 weeks |
The label also notes that jawline injection may temporarily change jaw function, so chewing can feel stiff for a few days, and that RADIESSE is visible on CT scans and may show on X-rays. Nodules are possible, especially when the product is placed too superficially.
As with any filler, the FDA warns that injection into a blood vessel can cause tissue damage, blindness or stroke. Because RADIESSE has no dissolving enzyme, careful technique matters even more. Sudden severe pain, skin that turns pale or dusky, or any change in vision after treatment needs emergency care: call 911.
Paying for RADIESSE and booking at Ultimate Male
A RADIESSE quote depends on how many syringes your jaw or folds need and whether a touch-up is planned. RADIESSE (+) comes in 1.5 cc and 0.8 cc syringes, and many men need more than one for a full jawline. Jaw contouring is cosmetic, so under IRS Publication 502 it is generally not payable with FSA or HSA funds. You pay per visit, no membership is needed, and financing through CareCredit, Prosper Healthcare Lending or Afterpay is available for RADIESSE plans.
At our San Gabriel and Downey clinics, RADIESSE is placed by our aesthetic nurses after an in-person jaw assessment, and you get a written quote before treatment. If a reversible gel is the better first step for you, that will be the recommendation. See all dermal filler treatments or book a RADIESSE consultation.
