Rejuran vs Skinvive: Hydration and Skin Quality Compared

October 25, 2026

If you follow skincare trends, you may have seen both Rejuran and Skinvive described as ways to get smoother, glowing skin from within. They are both injectable skin-quality treatments, but they come from different traditions: Rejuran is a Korean PN booster, while Skinvive is a hyaluronic acid microdroplet product from the Juvederm range. This guide explains how they compare and what is realistically available if you are visiting Busan.

Quick answer: Rejuran (Rejuran Healer) uses salmon-derived PN (polynucleotide) to support the skin's repair processes, so it suits thin, tired or sensitised skin and builds over a series of sessions. Skinvive is a lightly cross-linked hyaluronic acid injected in tiny droplets to improve hydration, smoothness and glow, and is often given as a single treatment. Rejuran is mainly about resilience and repair; Skinvive is mainly about hydration and surface smoothness. Skinvive is not offered at the clinic used for the examples here, but hyaluronic acid boosters such as Belotero Revive, a water glow injection or Rejuran HB (PN plus hyaluronic acid) cover similar goals.

What is Rejuran?

Rejuran Healer is made by PharmaResearch in Korea and contains PN purified from salmon DNA. PN supports fibroblast activity and a healthier skin environment, improving texture, elasticity and fine lines gradually. A series of 3 or more sessions 2–4 weeks apart is usually advised. Rejuran HB is a related product that adds hyaluronic acid, so it supports repair and hydration at the same time.

On evidence: PN boosters have supportive clinical data and long use in Korea, but marketing claims about salmon DNA "regenerating" skin should be read conservatively. Expect a gradual, natural improvement rather than a transformation.

What is Skinvive?

Skinvive is made by Allergan Aesthetics as part of the Juvederm family. It is a hyaluronic acid gel with lidocaine, injected as many tiny microdroplets into the skin of the cheeks. It is designed to improve skin smoothness and hydration rather than add volume. In the USA it was approved for improving cheek skin smoothness in adults, and results are generally reported to last several months, with a top-up often suggested around six months. Availability and approved uses vary by country.

Key differences

  • Ingredient: PN from salmon (Rejuran) vs cross-linked hyaluronic acid (Skinvive).
  • Main effect: repair, resilience and elasticity vs hydration, smoothness and glow.
  • Treatment plan: usually a series of about three sessions vs often a single session with periodic top-ups.
  • Speed: gradual over weeks vs hydration and smoothness noticeable soon after swelling settles.
  • Allergy note: Rejuran is unsuitable with a fish or salmon allergy; HA products are unsuitable with allergy to hyaluronic acid or lidocaine.

Who suits which

Rejuran may suit you if

  • Your skin is thin, fragile or slow to recover after sun or lasers.
  • You notice loss of bounce and fine lines alongside dryness.
  • You can return for a series of sessions.

A hyaluronic acid booster like Skinvive may suit you if

  • Your main concern is dryness, dullness and a lack of glow.
  • Your skin is otherwise in good condition.
  • You want a hydration boost before an event.

Closest options available in Busan

Since Skinvive itself is not on the menu at the Seomyeon clinic used here, these are the closest alternatives for hydration and skin quality:

  • Belotero Revive: lightly cross-linked hyaluronic acid with glycerol by Merz, injected in many tiny points to hydrate and soften fine lines without volume. Conceptually the nearest match to Skinvive.
  • Water glow injection: a soft, fine hyaluronic acid product spread across the face for moisture and glow.
  • Re2O: a hyaluronic acid-based booster for hydration and texture.
  • Rejuran HB: PN plus hyaluronic acid, for skin that is both dry and tired-looking.

Cost in Busan

Example prices at a clinic in Seomyeon:

  • Rejuvelook (Rejuran 2cc + Juvelook Skin 2cc) : from KRW 319,000
  • Rejuran HB 2cc : from KRW 390,000
  • Belotero Revive 2cc, 1 session : from KRW 590,000
  • Belotero Revive 2cc, 3 sessions : from KRW 1,490,000

Prices checked October 2026. They exclude 10% VAT, and prices change frequently. The clinic does not quote a price for Skinvive, and other clinics' prices are not given here.

What happens on the day

  1. Consultation: the doctor assesses dryness, fine lines, skin thickness and sensitivity, and asks about allergies (fish for PN, lidocaine or hyaluronic acid for HA products).
  2. Numbing: numbing cream for about 20–30 minutes.
  3. Injection: about 10–20 minutes of small, even injections. PN boosters can sting slightly more.
  4. After: small bumps or needle marks, usually settling within 1–2 days.

Recovery and aftercare

Side effects are similar across these boosters: small bumps, redness, mild swelling, tenderness and bruising that can take up to a week to fade. Rarely, infection, allergic reaction or persistent lumps can occur.

  • Avoid pressing or massaging the treated area.
  • Skip saunas and jjimjilbang, hot baths, alcohol and hard exercise on the day.
  • Use sunscreen and keep skin moisturised. Book a few days before photos or events.

Boosters should be postponed during pregnancy or breastfeeding and with active infection, cold sores or inflamed acne in the area.

Frequently asked questions

Is Skinvive the same as a water glow injection?

Both use hyaluronic acid to hydrate the skin, but they are different products with different gels and formulations. A doctor can explain how a specific product compares.

Can I combine Rejuran with a hyaluronic acid booster?

Yes. Repair and hydration complement each other; Rejuran HB does this in one product, and packages often pair Rejuran with a hydration injection.

Which lasts longer?

It varies. HA boosters typically need top-ups every few months, while Rejuran is given as a series and then maintained every few months. Your skin and lifestyle matter more than the label.

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?
