How Many Rejuran Sessions Do You Need in Korea?

October 25, 2026

Rejuran is one of the most requested skin boosters in Korea, and the question visitors ask most is simple: how many sessions will I actually need? The answer matters for both your budget and your travel plans, because Rejuran works best as a course rather than a one-off. This guide explains the usual number of sessions, the spacing, what to expect after each one, maintenance, and how to plan sessions around trips to Busan.

Quick answer: Most people are advised to have at least three Rejuran sessions spaced 2–4 weeks apart, with the clearest change in texture, elasticity and fine lines usually seen after the third. Very thin or damaged skin may need more. After the initial course, maintenance is often planned every few months, depending on age, skin condition and lifestyle. A single session during one trip can still help, but expect a modest change. In Seomyeon, Rejuran packages start from KRW 319,000 before 10% VAT, so budget for the full course.

Why Rejuran needs more than one session

Rejuran Healer contains PN (polynucleotide), a purified DNA-derived ingredient from salmon, which is thought to support the skin’s own repair processes and fibroblast activity. Unlike filler, it does not create an instant change. Each session starts or reinforces a gradual response in the skin, and spacing sessions lets each round build on the last. That is why a series gives steadier results than one larger treatment.

The typical schedule

  • Number of sessions: three or more for the initial course.
  • Spacing: every 2–4 weeks.
  • Course length: roughly 1–3 months from first to third session.
  • Maintenance: often every few months afterwards, adjusted to how your skin responds.

What affects how many you need

  • Skin condition: very thin, sun-damaged or slow-to-recover skin may need more than three.
  • Your goal: a general refresh may need fewer than treating fine lines and texture.
  • Area: the under-eyes are often treated with a smaller dedicated amount and may follow their own schedule.
  • Combinations: pairing Rejuran with other boosters, toning or lifting can change the plan.
  • Age and lifestyle: sun exposure, smoking and sleep all affect how long results last.

What to expect after each session

  • After session one: small bumps flatten within 1–2 days. Over the next 2–4 weeks, skin may begin to look healthier and more even, though changes are subtle.
  • After session two: many people notice better texture and a little more bounce.
  • After session three: elasticity, texture and fine lines usually show the clearest change.
  • Ongoing: results fade gradually; maintenance sessions help keep them.

Taking photos in the same light before each session helps you see gradual change that is easy to miss in the mirror. Results vary from person to person.

Can you do Rejuran in one trip?

Yes, but it depends on how long you are staying:

  • Short trip (under two weeks): one session is realistic. It can help skin quality, but set modest expectations.
  • Three to six weeks: two sessions 2–4 weeks apart are often possible.
  • Two to three months, or living in Korea: a full course of three is achievable.
  • Repeat visitors: some people plan sessions across return trips, or continue the course with a doctor at home.

Share your full dates when you book so the plan fits your schedule rather than the other way round.

How much does a Rejuran course cost in Busan?

At a clinic in Seomyeon, Rejuran is mainly offered in packages per session:

  • Rejuvelook (Rejuran 2cc + Juvelook Skin 2cc) : from KRW 319,000
  • Rejuran HB 2cc : from KRW 390,000
  • Booster package (Rejuran 2cc + Juvelook Skin 2cc + hydration injection 2cc + full-face skin Botox) : from KRW 590,000
  • CellREDM 7cc + Rejuran 2cc + LDM + hydrating mask : from KRW 690,000
  • Pick your boosters: choose 3 from CellREDM, Re2O, Rejuran 4cc or Juvelook 1 syringe : from KRW 1,190,000

For a three-session course of the Rejuvelook package, for example, budget roughly three times the per-session price plus 10% VAT. Prices checked October 2026. They are in Korean won and exclude 10% VAT, which is added at payment. Prices can change, so confirm the current price when you book.

What happens at each session

  1. Consultation. The doctor checks skin thickness, texture, fine lines, recent procedures and allergies, especially to fish.
  2. Numbing. Numbing cream is applied for about 20–30 minutes.
  3. Injections. About 10–20 minutes. PN boosters can sting slightly more than some others, and small blebs form.
  4. Follow-up. The next session is planned 2–4 weeks later.

Side effects and aftercare between sessions

Common effects are small bumps or injection marks for 1–2 days, redness, mild swelling or tenderness, and bruising that fades over several days, more likely around the eyes. Rarely, infection, allergic reaction or persistent lumps can occur.

Aftercare tips

  • Stay upright and avoid rubbing the treated area for 3–4 hours.
  • On the day, skip saunas and jjimjilbang, hot baths, hard exercise and alcohol.
  • Leave make-up until the next day.
  • Use sunscreen daily between sessions to protect the result.

Rejuran is not suitable with a fish or salmon allergy, during pregnancy or breastfeeding, with an active infection, cold sore or inflamed acne, an uncontrolled autoimmune condition, or a tendency to keloids.

Frequently asked questions

Is one Rejuran session worth it?

It can help skin quality, especially if you are combining it with other treatments, but most of the visible change comes from a course.

Can I have sessions closer than two weeks apart?

Spacing of 2–4 weeks is usually advised so each session can build on the last. Ask the doctor before shortening the interval.

How often should I do maintenance?

Often every few months after the initial course, adjusted to your skin, age 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?
