Radiesse has a documented safety record; a review of 5,081 treatments found adverse events in only 3% of cases, most of them mild, temporary nodules that resolved without intervention.
Radiesse is a well-studied calcium hydroxylapatite filler with a strong safety record when injected by a trained doctor into suitable, deeper areas. Most side effects are mild and short-lived, such as swelling, bruising or an occasional small nodule. Unlike hyaluronic acid, it cannot be dissolved with hyaluronidase, so precise placement and avoiding high-risk zones matter most.

Radiesse has a well-documented safety profile when it is placed correctly. In a review of 5,081 calcium hydroxylapatite treatments, adverse events were reported in only 3% of cases, and 96% of those were nodules that in most cases were not visible and resolved without intervention. Long-term studies over 18 months found no systemic effects, with satisfaction acceptable or better in about 87% of patients. As with any filler, serious complications such as vascular problems are very rare and are minimised by trained technique and correct patient selection.
Radiesse is made of calcium hydroxylapatite (CaHA) microspheres, a mineral found naturally in bone, suspended in a gel. It gives immediate volume and then acts as a scaffold that stimulates the skin’s own collagen, so results tend to last around 12 to 18 months. The key difference from hyaluronic acid is that Radiesse is not reversible with hyaluronidase. Because it cannot simply be dissolved, correct depth, precise placement and avoiding high-risk facial zones are even more important, and it is generally reserved for deeper contour work rather than delicate areas.
Reberry Clinic is a dermatology clinic and injectable treatments are performed by the clinic’s doctors. The clinic is consultation-led and serves international patients across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport) with English-speaking support, so your suitability, anatomy and expectations are reviewed before any Radiesse is injected.
Radiesse works in two stages: the CaHA microspheres add immediate volume, then over months they stimulate new collagen while the gel carrier is absorbed. Because the microspheres are firm and the material is not dissolvable, a trained injector places it deep, often against bone or in the subcutaneous plane, in areas like the jawline, chin, cheeks or hands, and avoids very superficial placement that can cause visible nodules. High-risk vascular zones and thin-skinned areas such as the under-eye or lips are generally avoided.
The fact that Radiesse cannot be reversed with hyaluronidase makes injector skill and patient selection central to safety. The clinic’s doctors screen your history, plan conservative volumes and discuss whether a reversible HA filler or a collagen-stimulating booster is a better fit if you want an easily adjustable result. This way the material is matched to the goal, and Radiesse is used where its longevity and lift are an advantage rather than a liability.

A doctor reviews your history and goals and confirms the area suits Radiesse rather than a reversible filler, in 1 consultation.
Treatment is limited to suitable deeper areas such as the jawline, chin or cheeks, avoiding 2 to 3 high-risk zones like the under-eye.
CaHA is injected deep, against bone or in the subcutaneous plane, to lower the chance of visible nodules.
The gel is injected slowly in small aliquots, often via cannula, across 1 careful pass to reduce the risk of vascular entry.
Your result is checked and, because it is not dissolvable, any massage for a firm nodule is guided over the first 1 to 2 weeks.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
An English-language consultation reviews your history and goals and confirms Radiesse suits your area rather than a reversible filler.
After cleansing and numbing, the doctor injects genuine Radiesse deep and slowly; a session commonly takes around 20 to 40 minutes.
A single visit fits a short trip, with a review arranged if any firm area needs guided massage.
You see volume immediately, with collagen-based refinement developing over the following weeks to months.
Results last roughly 12 to 18 months; avoid heat, alcohol and heavy exercise for 24 to 48 hours and massage only as advised.
Radiesse is a well-studied calcium hydroxylapatite filler with a strong safety record, and a review of 5,081 treatments found adverse events in only 3% of cases, mostly mild nodules. Because it is not dissolvable, precise placement matters most. Safety depends on suitable zones and trained delivery, which is why a consultation comes first when you discuss injectable fillers.
No, unlike hyaluronic acid, Radiesse is calcium hydroxylapatite and cannot be dissolved with hyaluronidase, so a result cannot simply be reversed. This is why placement, conservative volumes and patient selection are so important. If you want an easily adjustable option, a doctor may recommend a reversible HA filler instead at consultation.
The most common side effects are mild and short-lived: swelling, bruising, redness or tenderness that settle within days. The main filler-specific issue is a small nodule, reported in most of the 3% of cases that had any adverse event, and these often resolve on their own. Serious vascular problems are very rare with trained technique.
Because it is firm and non-dissolvable, Radiesse is placed deep in contour areas such as the jawline, chin, cheeks and hands, and thin-skinned or high-risk zones like the under-eye and lips are generally avoided. This zone discipline keeps nodules and vascular risk low. Your doctor confirms whether your area suits Radiesse during the assessment before treatment.
Most patients feel a brief pinch and pressure, which is generally manageable because numbing cream is applied and Radiesse can be mixed with lidocaine. Deeper placement means sensation is usually moderate. Comfort is checked during the session and technique is eased, so tell your doctor if anything feels sharp so the approach can be adjusted.
Radiesse typically lasts around 12 to 18 months, often longer than many HA fillers, because the CaHA microspheres also stimulate your own collagen. It is not permanent, so the material is gradually absorbed. Your doctor estimates longevity for your plan and discusses timing for any top-up rather than over-filling a non-dissolvable material.
Yes, calcium hydroxylapatite is not pigment-dependent, so Radiesse suits a wide range of skin tones, and a 2025 study using it in Asian patients reported significant contour improvement with mild, transient side effects. Correct depth still matters. Your suitability is confirmed during the filler assessment before any injection.
Small firm areas can occur and often soften over the first 1 to 2 weeks, sometimes helped by guided massage your doctor demonstrates. Because Radiesse is not dissolvable, a persistent nodule is managed by review rather than an enzyme. Contact the clinic if a lump is tender, growing or does not settle so it can be assessed.
Radiesse is generally avoided in pregnancy or breastfeeding, in very thin-skinned or high-risk zones like the under-eye, over active infection, and in people prone to nodules or granulomas. Bleeding disorders and blood thinners need review. Screening at consultation is how these are identified before any plan is set, so disclose your full medical history.
Both add volume, but Radiesse is calcium hydroxylapatite that stimulates collagen, lasts well and is not dissolvable, while Juvederm is a reversible HA gel that suits delicate areas. Radiesse is better for firmer deep contour, HA for correctable, versatile work. Your doctor recommends the option whose profile best fits your goal and area.
Yes, Radiesse is often staged with skin-quality treatments or a reversible filler in other zones, since it handles deep contour while other options refine skin or delicate areas. Timing and order matter to keep results even and safe. Your doctor sequences any combination, for example with a collagen booster, at consultation.
They can be; a very low price sometimes signals a non-genuine or diluted product or a rushed, undertrained injector, all of which raise the risk of nodules or misplacement in a non-dissolvable material. Value and safety go together. Ask to see a sealed, authentic product and confirm who is injecting, rather than choosing on headline price.
Aftercare is simple: avoid heat, alcohol and heavy exercise for 24 to 48 hours, use gentle skincare, and massage only if and as your doctor advises, since firm areas can respond to guided pressure. Most patients resume normal activities the same day. Your doctor provides written instructions and you can follow up from abroad if any question arises.
Most contour goals use a modest, planned amount rather than large volumes, because the material is firm and non-dissolvable, so a doctor builds gradually across sessions if needed. Over-filling raises risk and looks unnatural. Your plan is based on your anatomy and goal at assessment, keeping the result balanced and within a comfortable margin.
Yes, Reberry Clinic serves international patients with English-speaking support across three Seoul-area locations, including one near Incheon Airport, so screening, consent and aftercare are explained in English. You are assessed before treatment and supported afterward from abroad. Message us on WhatsApp to discuss your suitability for Radiesse.
Yes, most patients fly the same or next day, since downtime is minimal and any bruising or swelling settles quickly, so it fits a short Seoul trip. Cabin pressure does not affect the filler. You receive a written aftercare plan so you can follow up on your Radiesse from abroad if needed.
