Rejuran HB in Busan

#PNPlusHA · #RepairAndHydrate · #DewyVitality · #TiredSkinCare

Rejuran HB is a skin booster that combines PN with hyaluronic acid. It supports repair and hydration together, bringing dewy vitality and elasticity back to dry, tired skin.

Quick answer: Rejuran HB is a skin booster that combines PN (polynucleotide) with hyaluronic acid to support skin repair and hydration at the same time. At Art of Shine Clinic in Seomyeon, Busan, it takes about 10–20 minutes after numbing cream, with mild swelling or needle marks for 1–2 days. A series of 3 or more sessions 2–4 weeks apart is usually advised. Rejuran HB 2cc is listed at KRW 390,000 (excl. 10% VAT).

At a glance

What is Rejuran HB?

Rejuran HB is part of the Rejuran range by PharmaResearch, a Korean company. Like the original Rejuran, it contains PN (polynucleotide) derived from salmon DNA, which supports the skin's natural repair processes. The HB version adds hyaluronic acid for extra hydration.

It suits skin that is both dry and tired-looking, with fine lines or loss of bounce. If repair is your main concern, Rejuran Healer is the classic choice; for hydration alone, Re2O or Belotero Revive may be enough.

How Rejuran HB works

PN provides building blocks that support cell repair and a healthier skin environment, while hyaluronic acid draws moisture into the skin. Together they improve hydration, elasticity and overall skin condition over a series of sessions.

1. Consultation: your doctor assesses dryness, fine lines and skin condition, and checks for fish allergies.
2. Treatment: after numbing cream, Rejuran HB is injected in small, even points across the face.
3. After: you can return to daily life; repeat sessions every 2–4 weeks build the result.

Why patients choose Rejuran HB

• PN plus hyaluronic acid — repair and hydration in one treatment.
• From an established range — part of PharmaResearch's Rejuran line.
• Dewy, healthier skin — aimed at dry, tired-looking complexions.
• Short appointment — about 10–20 minutes after numbing cream.

Who is Rejuran HB for — and when we suggest something else

Good candidates

• Your skin is both dry and tired-looking, with a dull, stressed surface.
• Fine lines show more when your skin is dehydrated.
• You want repair and hydration from one booster.
• You have tried a hydration booster before and want more resilience.
• You can plan three or more sessions 2–4 weeks apart.

We may suggest something else if…

• Repair and elasticity matter more than hydration — classic Rejuran Healer may be enough.
• You only want hydration and glow — Re2O is a simpler option.
• Texture, pores or scars are the priority — Juvelook Skin targets collagen there.
• You are allergic to fish or salmon-derived products. Tell us first; Dr. Park will suggest a non-PN alternative.
• You are pregnant or breastfeeding, or have an active skin infection. We will wait.

What happens at your Rejuran HB session in Seomyeon

1. Message us on WhatsApp first. Send us on WhatsApp (+82 10-2689-0370) a daylight photo and your dates. Mention any fish allergy or previous reaction to boosters.
2. Consultation with Dr. Park. She checks dryness, fine lines, skin thickness and sensitivity. She confirms whether HB or classic Rejuran Healer suits you better.
3. Preparation and numbing. Your skin is cleansed and numbing cream is applied for about 20–30 minutes.
4. The treatment. Injecting takes about 10–20 minutes. Expect pricking and small blebs; PN boosters can sting a little.
5. Out the door and follow-up. Mild swelling or needle marks may last 1–2 days. Your next session is usually 2–4 weeks later.

How Dr. Park plans your Rejuran HB treatment

Dr. Park places Rejuran HB in small, shallow deposits across the face. Areas that look dry and creased, such as the cheeks and under-eye margin, often get closer spacing.

Our listed package is Rejuran HB 2cc. That amount is planned across the zones that need it most. Sessions are spaced 2–4 weeks apart, and three or more are usually advised.

She aims for dewy, resilient skin rather than visible change in shape. Dr. Park is a REJURAN & REJUVIEL Expert Member (PharmaResearch), the company behind Rejuran.

Rejuran HB results: what to expect and when

• First days: small bumps and needle marks settle within 1–2 days.
• Weeks 1–3: skin feels more hydrated and looks fresher.
• After 3 sessions: elasticity and overall condition improve most.
• Ongoing: how long results last varies by person; plan maintenance with your doctor.

Results vary by person.

Side effects, risks and who should avoid Rejuran HB

Rejuran HB is generally well tolerated when performed by a doctor. Possible side effects include:

• Small bumps or visible injection marks for 1–2 days
• Redness, mild swelling or tenderness
• Bruising at some injection points, which fades over several days
• Rarely, infection, allergic reaction or persistent lumps — contact the clinic if anything worsens

Not suitable if you: are pregnant or breastfeeding; are allergic to fish or salmon-derived ingredients; have an active skin infection, cold sore or inflamed acne in the area; have an uncontrolled autoimmune condition; or tend to form keloid scars. Tell your doctor about all medications, especially blood thinners.

Rejuran HB vs Rejuran Healer and Re2O: which should you choose?

Rejuran HB sits between a PN repair booster and a hydration booster.

Choose Rejuran HB if your skin is both dry and tired. Choose Rejuran Healer if repair is the main need, and Re2O if you only need hydration.

Aftercare after Rejuran HB

• For about 3–4 hours, avoid lying face-down and do not rub the treated area.
• On the day of treatment, skip saunas, hot baths, strenuous exercise and alcohol.
• Do not massage or press firmly on the treated area.
• Temporary swelling, bruising or tenderness can occur and usually settles on its own.
• Results and how long they last vary with your skin condition and lifestyle.

Downtime after Rejuran HB, and flying home

Small bumps usually flatten within hours to a day, and needle marks fade in 1–2 days. Do not lie down or rub your face for 3–4 hours. Skip saunas, hot baths, alcohol and hard workouts that day. Avoid massage or pressure on the area.

A gentle afternoon in Seomyeon or a seaside walk is usually fine. Leave jjimjilbang visits for later in the trip. Most people resume make-up the next day. Keep skin moisturised on the flight home. Share your flight date with Dr. Park at consultation. See our aftercare tips for travellers.

What does HB mean in Rejuran HB?

Rejuran HB is a version of Rejuran that adds hyaluronic acid to the PN base. In practice, it is chosen when hydration is needed alongside repair. The core ingredient, salmon-derived PN, is the same family as Rejuran Healer. The added hyaluronic acid gives a more moisturising effect. Product names and formulations can change between markets. If you want the exact ingredient list, ask Dr. Park to show you the product label at your visit. She can also explain why she chose HB rather than Healer for your skin.

Is Rejuran HB less painful than Rejuran Healer?

Many people find PN boosters sting a little, and comfort varies widely. Numbing cream is applied for about 20–30 minutes first in every case. Some patients report Rejuran HB feels more comfortable, but this is individual. Pain also depends on the area treated, your skin thickness and your stress level that day. Tell the team if you are sensitive; you can ask for a break at any time. Choose the product for your skin's needs, not comfort alone.

Can I have Rejuran HB if I'm allergic to fish?

Tell us before booking. Rejuran products contain PN derived from salmon. A fish allergy does not always mean a reaction, but caution is sensible. Dr. Park will ask about your allergy history and how severe past reactions were. If there is real doubt, she will suggest a booster without PN, such as Re2O or Juvelook Skin. Never hide an allergy to get a specific treatment; your safety comes first. Bring any allergy documents you have, translated if possible, to your consultation.
