Rejuran Healer vs Rejuran HB: Key Differences

October 25, 2026

Rejuran is one of the best-known Korean skin boosters, and visitors to Busan often discover there is more than one version on the menu. The two you will see most are Rejuran Healer, the classic, and Rejuran HB. They come from the same family and share the same core ingredient, so the choice comes down to whether your skin mainly needs repair, or repair and hydration together.

Quick answer: Both Rejuran Healer and Rejuran HB are made by PharmaResearch and contain PN (polynucleotide) derived from salmon DNA, which supports the skin's own repair processes. Rejuran HB adds hyaluronic acid, so it also draws moisture into the skin. Choose Rejuran Healer when thin, fragile or slow-to-recover skin is the main concern; choose Rejuran HB when your skin is both dry and tired-looking. Both are given as a series of about 3 sessions 2–4 weeks apart.

What they have in common

  • Same maker: PharmaResearch, a Korean company.
  • Same core ingredient: PN purified from salmon DNA, which supports fibroblast activity and a healthier skin environment.
  • Same technique: small, evenly spaced injections across the face after numbing cream.
  • Same pace: gradual improvement over a series, with no change to face shape.
  • Same allergy caution: neither is suitable if you are allergic to fish or salmon-derived ingredients.

What makes them different

Rejuran Healer

The classic formula focuses on PN. Its main aim is repair and resilience: improving texture, elasticity and fine lines in skin that feels thin, fragile or slow to recover after sun, stress or laser treatments. It is often used before or after lifting and laser treatments to strengthen skin quality, and around the delicate eye area as well as the full face.

Rejuran HB

Rejuran HB combines PN with hyaluronic acid. PN supports repair while hyaluronic acid attracts and holds water, so the result leans towards hydration, dewiness and bounce as well as resilience. It suits a dull, stressed, dehydrated complexion where fine lines show more when the skin is dry.

Side-by-side summary

  • Rejuran Healer: PN only. Best for repair, thin or sensitised skin, texture and elasticity.
  • Rejuran HB: PN plus hyaluronic acid. Best for skin that is dry and tired at the same time.
  • Session time: about 10–20 minutes for both, after 20–30 minutes of numbing cream.
  • Downtime: small bumps or needle marks for 1–2 days for both.

Who suits which

Rejuran Healer may suit you if

  • Your skin feels thin, fragile or easily irritated.
  • You want to support recovery around laser or lifting treatments.
  • Fine lines, rough texture and loss of bounce are your main concerns.

Rejuran HB may suit you if

  • Your skin feels dry deep down and looks dull or stressed.
  • Fine lines look worse when you are dehydrated.
  • You have tried a simple hydration booster and want more resilience.

Consider something else if

If you only want hydration and glow, a hyaluronic acid booster such as Re2O or a water glow injection is simpler. If texture, pores or scars are the priority, Juvelook Skin targets collagen there. If you are allergic to fish, ask for a non-PN alternative. Sagging needs lifting treatments rather than boosters.

Cost in Busan

Example prices at a clinic in Seomyeon:

  • Rejuran HB 2cc : from KRW 390,000
  • Rejuvelook (Rejuran 2cc + Juvelook Skin 2cc) : from KRW 319,000
  • 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

Prices checked October 2026. They exclude 10% VAT, which is added at payment, and prices change frequently. Rejuran Healer is mostly offered within packages, often alongside a hydration injection, which in practice gives a similar repair-plus-hydration effect to HB.

What happens on the day

  1. Consultation: the doctor checks dryness, fine lines, skin thickness, sensitivity and recent procedures, asks about fish allergy, and confirms which version suits you.
  2. Numbing: numbing cream for about 20–30 minutes.
  3. Injection: about 10–20 minutes. PN boosters can sting slightly more than some others, and small blebs form.
  4. After: you can go about your day; plan the next session 2–4 weeks later.

Results timeline

  • First 1–2 days: bumps at injection points flatten out.
  • Weeks 2–4: skin begins to look healthier and more even; HB may feel more hydrated sooner.
  • After 3 sessions: elasticity, texture and fine lines show the clearest change.
  • Ongoing: maintenance is usually planned every few months.

On evidence: PN boosters have supportive data and long use in Korea, but improvements are gradual and modest rather than dramatic. Results vary by person.

Side effects and aftercare

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

  • Avoid pressing, massaging or rubbing the treated skin.
  • Skip saunas and jjimjilbang, hot baths, alcohol and hard exercise on the day.
  • Use sunscreen and a gentle moisturiser; makeup is usually fine the next day.

Neither is suitable during pregnancy or breastfeeding, with active infection, cold sores or inflamed acne in the area, an uncontrolled autoimmune condition, or a tendency to keloid scars.

Frequently asked questions

Is Rejuran HB stronger than Rejuran Healer?

Not stronger, just different. HB adds hyaluronic acid for hydration; Healer focuses on PN for repair. The better choice depends on whether dryness is part of your concern.

Can I switch between them in a series?

Sometimes. A doctor may adjust the product between sessions as your skin changes, for example starting with repair and adding hydration later.

Can I fly after Rejuran?

Yes, flying is generally fine. Cabin air is dry, so moisturise well, and avoid pressing on the face while bumps settle.

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?
