Radiesse in Busan: Collagen-Stimulating Injectable Guide

October 25, 2026

Radiesse is an injectable that sits between a classic filler and a collagen stimulator: it gives visible support straight away and encourages your own collagen over the following months. In Busan it is mainly used for folds around the nose and mouth and for neck lines, and it appeals to visitors who want a longer-lasting result from a short stay. This guide explains how it works, who it suits, what it costs and what to expect afterwards.

Quick answer: Radiesse, made by Merz Aesthetics, is calcium hydroxylapatite (CaHA) microspheres suspended in a water-based gel. The gel adds volume immediately, and the microspheres then stimulate collagen, so firmness can keep improving. It is used for nasolabial folds, mouth-corner lines and, diluted, for neck lines. Treatment takes about 15–20 minutes after numbing cream, you can usually return to daily life straight away, and results typically last about 12–18 months. In Seomyeon, one syringe starts from KRW 590,000 before 10% VAT.

What is Radiesse?

Calcium hydroxylapatite is a mineral similar to one found naturally in bone. In Radiesse, tiny smooth microspheres of CaHA are carried in a gel. It has been used in aesthetic medicine for many years and is one of the better-studied collagen-stimulating injectables.

How it works: two stages

  1. Immediate support. The gel carrier fills and lifts the treated crease or area as soon as it is injected.
  2. Collagen stimulation. Over the following weeks and months, the gel is absorbed and the microspheres act as a scaffold that prompts fibroblasts to produce new collagen. The body gradually breaks down the microspheres.

When diluted (sometimes called “hyperdiluted”), Radiesse is spread more thinly so it works mainly as a skin-quality and firmness treatment rather than a filler, which is how it is often used on the neck.

Who Radiesse suits, and who should choose something else

It tends to suit you if

  • You have deepening nasolabial folds or lines at the mouth corners.
  • Horizontal neck lines or crepey neck skin bother you.
  • You want volume now plus gradual firmness over the following months.
  • You prefer a longer-lasting option and are happy to repeat every 12–18 months.
  • You are comfortable with a product that cannot be dissolved with an enzyme.

Something else may suit you better if

  • Lips or under-eyes: soft hyaluronic acid (HA) fillers are usually preferred, and Radiesse is not typically used in the lips.
  • You want reversibility: an HA filler can be dissolved with hyaluronidase if needed.
  • You only want skin quality: a booster such as Juvelook Skin is more suitable.
  • You want slow, collagen-only change: Juvelook Volume or Olidia build volume gradually without immediate correction.

Radiesse is not suitable during pregnancy or breastfeeding, over an active infection or inflammation, with a bleeding disorder or known allergy to a component, or if you tend to form keloids or have a history of granulomas.

How much does Radiesse cost in Busan?

At a clinic in Seomyeon, Radiesse is priced per syringe:

  • Radiesse CaHA, 1 syringe, 1 session : from KRW 590,000
  • Radiesse CaHA, 1 syringe, 3 sessions : from KRW 1,490,000

Prices checked October 2026. They are in Korean won and exclude 10% VAT, which is added at payment on the day. Prices can change, so confirm the current price when you book. The amount you need depends on the area and depth of the lines.

What happens on the day

  1. Message first with photos of the areas you want treated, any previous filler details and your travel dates.
  2. Consultation. The doctor examines fold depth, skin thickness and any earlier filler, and confirms whether Radiesse is right for each area or whether an HA filler is safer.
  3. Numbing. The area is cleansed and numbing cream is applied for about 20–30 minutes.
  4. Injection. Radiesse is placed with a fine needle or cannula in about 15–20 minutes, then gently shaped. You may feel pressure and mild discomfort.
  5. After. You can return to your day; some fullness is visible straight away.

Already had filler?

Tell the doctor which product was used, where and when. Recent filler may still be settling, and Radiesse is not usually layered directly over fresh HA filler in the same spot. If old filler has migrated, dissolving it first may be suggested.

Results and timeline

  • Immediately: volume and support are visible.
  • First week: swelling or bruising settles.
  • Months 2–3: collagen stimulation adds firmness and improves skin quality.
  • Months 12–18: the effect gradually fades; timing varies by person.

Side effects and safety

Radiesse is generally well tolerated when performed by a doctor. Possible effects include swelling, redness, tenderness or bruising for a few days, and small lumps or unevenness that may need review. Rarely, infection or nodules can occur. Very rarely, any injectable can block a blood vessel; seek help immediately for skin colour changes, severe pain or vision problems.

Why Radiesse cannot be dissolved

Hyaluronidase, the enzyme used to dissolve HA filler, only breaks down hyaluronic acid. It has no effect on calcium hydroxylapatite, so the body clears Radiesse gradually instead. That is part of why it lasts longer, and why careful, conservative placement matters. If you are unsure, starting with an HA filler and adding Radiesse later is a reasonable path.

Aftercare tips

  • Avoid touching or pressing firmly on the treated area.
  • On the day, skip saunas, hot baths, strenuous exercise and alcohol.
  • For 1–2 weeks, avoid strong massage, facial treatments and heat on the treated area.
  • Make-up over injection points is usually best left until the next day.

Planning Radiesse around a trip

Gentle sightseeing is fine the same day. Postpone jjimjilbang and hot-spring visits for at least the first week. Staying a few days after treatment is wise, so that symmetry can be checked before you leave. Tell the doctor your flight date at the consultation, and contact the clinic if unevenness, lumps or discomfort persist.

Radiesse vs other options

  • Radiesse : CaHA filler with collagen stimulation. Best for: folds, mouth lines and neck lines; about 12–18 months.
  • HA wrinkle filler : hyaluronic acid gel. Best for: precise, reversible correction; about 6–12 months.
  • Juvelook Volume : PDLLA with HA. Best for: gradual, subtle volume over a series.
  • Olidia : PLLA collagen stimulator. Best for: broad, gradual volume over a series.

Frequently asked questions

Does Radiesse hurt?

With numbing cream applied for 20–30 minutes first, most people feel light pricking and mild pressure.

Is Radiesse good for neck lines?

It is one of the options. On the neck it is usually diluted and spread thinly to support the skin; very deep, fixed lines may also need a soft HA filler.

How long does Radiesse last?

Usually about 12–18 months, depending on the area, your metabolism and lifestyle.

Ultherapy is one of the most requested non-surgical lifting treatments in Korea, and Busan has become a popular place to have it done, especially for visitors who want to combine a treatment with a city break by the sea. This guide explains how Ultherapy works, who it suits, what it costs in Busan, and what recovery really looks like, so you can decide whether it fits your goals and your travel plans. Quick answer: Ultherapy uses focused ultrasound, guided by real-time imaging, to heat the deep supporting layer of the face (the SMAS) and trigger new collagen. A session takes about 30–60 minutes after numbing cream, there is usually no downtime, the lift builds over 2–6 months, and results typically last 6–12 months. In Busan, packages generally start from around KRW 790,000 before 10% VAT. What is Ultherapy? Ultherapy (often called Ulthera) is a micro-focused ultrasound device made by Merz Aesthetics. Like other HIFU treatments, it delivers concentrated ultrasound energy beneath the skin. What sets it apart is its built-in imaging: the practitioner can see the layers of the skin on screen and place each line of energy at the intended depth, including the SMAS, the same layer that is tightened in a surgical facelift. Each line creates tiny heated points that contract the tissue and start the body's collagen renewal process. Rather than an instant change, the skin firms and lifts gradually over the following months. Benefits of Ultherapy Reaches the deep support layer. Energy can be delivered down to the SMAS, which is why Ultherapy is used for sagging rather than surface texture alone. Imaging-guided precision. Seeing the tissue before each line helps place energy where it is needed and away from bone. No incisions and no downtime. Most people return to their day straight away. Natural, gradual change. The lift develops as collagen rebuilds, so results look like your own face, only firmer. One session a year for many people. A single treatment is usually enough for a visible change, repeated every 6–12 months. Who is a good candidate? Ultherapy tends to suit people in their 30s to 60s whose cheeks, jowls or brows have started to drop, or who have a softer jawline and some looseness under the chin. It is less helpful when the main concern is crepey texture rather than sagging (radiofrequency treatments such as Thermage FLX often suit that better), or when the face is very thin and hollow, in which case restoring volume may matter more than tightening. How much does Ultherapy cost in Busan? Ultherapy is priced by the number of lines (shots). Around 300 lines is typical for targeted areas such as the jawline and lower cheeks, while around 600 lines allows fuller coverage of the face and under the chin. In Busan, Ultherapy is often sold as a package combined with a skin booster or skin Botox. Ultherapy 300 lines + full-face skin Botox : from KRW 790,000 Ultherapy 600 lines + full-face skin Botox : from KRW 1,690,000 Prices checked October 2026. Korean clinic prices for cosmetic treatments are quoted in won and exclude 10% VAT, which is added at payment. Prices can change, so always confirm the current price when you book. When comparing quotes, check the number of lines included, whether the device is genuine Ultherapy or Ultherapy PRIME rather than a different HIFU machine, what is bundled in the package, and whether VAT is included in the figure you were given. What happens during a session Consultation. The doctor assesses sagging, fat and skin thickness, then plans the areas, depths and number of lines. Numbing. Numbing cream is applied for about 30 minutes, then the skin is cleansed and a gel is applied for the imaging probe. Treatment. The transducer shows the skin layers on screen and delivers focused ultrasound over about 30–60 minutes. Areas close to bone, such as the jawline, can feel prickly or warm. Straight back to your day. Mild redness is common and usually fades within hours. Results: what to expect and when Right after treatment: some people notice slight tightening; mild redness is normal. Months 2–3: lifting and firmness become visible as collagen renews. Months 3–6: results usually reach their peak. Months 6–12: the effect gradually fades with natural ageing; a repeat session maintains it. Results and timing vary from person to person. Even, well-planned coverage matters more for a natural result than simply using the maximum number of lines. Recovery, side effects and aftercare Ultherapy has very little downtime. The most common effects are redness or mild swelling that settles within hours to a few days, and tenderness or a bruised feeling along the jaw that can last a few days. Rarely, people experience temporary numbness, small bruises, welts or nerve irritation. Aftercare tips On the day of treatment, avoid saunas and jjimjilbang, hot baths, alcohol and strenuous exercise. Use sunscreen carefully for 1–2 weeks and avoid rubbing or scratching the treated area. Keep the skin well moisturised; makeup can usually be applied once the skin has calmed. Who should wait or avoid it Ultherapy is not recommended during pregnancy, over an active skin infection, open wound or severe acne in the area, or near metal implants or a pacemaker. Tell your doctor about any recent fillers, threads or other procedures in the area. Planning Ultherapy around a trip to Busan Because there is no real downtime, Ultherapy fits easily into a short stay. You can usually go sightseeing the same afternoon, and flying is generally fine, although jaw tenderness can feel more noticeable when chewing on the plane. Booking the treatment early in your trip gives you a few days to settle before you fly home. Share your flight date at the consultation so the plan fits your schedule. Ultherapy vs other lifting options Ultherapy : Focused ultrasound with real-time imaging. Best for: sagging cheeks, jowls and brows. Ultherapy PRIME : Newer Ultherapy platform with upgraded imaging. Best for: the same goals on the latest hardware. Thermage FLX : Monopolar radiofrequency heating the deep dermis. Best for: crepey skin and overall firmness. Shurink Universe : HIFU at set depths, without imaging. Best for: jawline and budget-friendly maintenance. In short, choose Ultherapy for an imaging-guided lift of deeper sagging, Thermage FLX when skin texture is the bigger concern, and Shurink Universe for more frequent, lower-cost upkeep between sessions. Frequently asked questions Does Ultherapy hurt? Most people describe it as warm, prickly pulses, strongest over bony areas. Numbing cream is applied beforehand to keep it comfortable. How many sessions will I need? One session is usually enough for a visible change. Many people repeat it every 6–12 months to maintain the result. Is 300 or 600 lines right for me? 300 lines generally focuses on priority areas such as the jawline and lower cheeks, while 600 lines covers the full face and under the chin more thoroughly. The right number depends on your degree of sagging and the areas you want treated. Thinking about Ultherapy in Busan?
