Rejuran Healer vs Rejuran HB: Key Differences
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.

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
- Consultation: the doctor checks dryness, fine lines, skin thickness, sensitivity and recent procedures, asks about fish allergy, and confirms which version suits you.
- Numbing: numbing cream for about 20–30 minutes.
- Injection: about 10–20 minutes. PN boosters can sting slightly more than some others, and small blebs form.
- 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.
