Rejuran vs. Rejuran HB: What's Different?
Rejuran and Rejuran HB sound like the same treatment with two names, but a single ingredient sets them apart. Here's how the formulas differ and which one tends to fit which skin concern.
Planning a trip to Seoul?
If you've been researching skin boosters, you've probably run into the name Rejuran more than once — and if you've also seen Rejuran HB or Rejuran Healer in the mix, you're not alone in wondering whether they're just the same shot with different labels. They're not quite the same, though the difference comes down to a single added ingredient rather than a totally different treatment. In this article, we'll cover what Rejuran actually contains, how Rejuran HB differs from the original, which one tends to fit different skin concerns, and what a normal recovery looks like versus a sign to call your provider.
What Is Rejuran, Exactly?
Rejuran is a skin booster built around polynucleotides (PN) — purified DNA fragments, typically derived from salmon, that are injected into the skin to support tissue repair. Rather than adding volume the way a dermal filler does, PN works by encouraging your skin's own repair processes and stimulating collagen production over time.
Research on polynucleotide-based treatments has linked them to tissue repair and regeneration, with improvements in skin texture and elasticity that build gradually rather than appear overnight. That's why most people don't see a dramatic change on the day of treatment — the real payoff tends to show up over the following weeks, as your skin's texture and tone calm down.
Rejuran vs. Rejuran HB: What's Actually Different?
Here's the short answer: the core ingredient is the same, but Rejuran HB adds hyaluronic acid (HA) into the mix. Original Rejuran — sometimes marketed as Rejuran Healer — is PN-only, so it's built around repair and texture. Rejuran HB combines PN with HA, which means you get the repair benefits plus a boost of hydration and a bit of immediate plumpness.
Right after treatment: With HB, a lot of people notice a more hydrated, slightly plumper look almost right away, since HA pulls in water. Original Rejuran tends to feel more subtle in the first day or two, since there's no HA drawing in moisture on top of the PN.
| Category | Original Rejuran | Rejuran HB |
|---|---|---|
| Core ingredient | Polynucleotides (PN) | PN + hyaluronic acid (HA) |
| Main focus | Skin repair, texture | Repair plus hydration and mild volume |
| Right-after feel | Subtle | Plumper, more hydrated |
| Best-suited concern | Rough texture, low elasticity | Dryness, fine lines |
| Injection depth | Mostly dermal | Mostly dermal |
A review of polynucleotide-based procedures found they're commonly used to improve skin texture, elasticity, and hydration — usually across a series of sessions rather than a single visit. That last point matters more than the product name does: how many sessions you get, spaced how far apart, and whether your provider adjusts the formula to your skin tends to move the needle more than which version you pick.
Which One Fits Your Skin Goals?
Instead of starting with the product name, it helps to start with what's actually bothering you. If rough texture and lost elasticity are your main concerns, original Rejuran is usually the better starting point. If dryness or fine lines paired with a craving for that hydrated, plumped look are what you're after, Rejuran HB tends to be the better fit.
Skin thickness and how quickly you heal vary a lot from person to person, so it's common to start conservatively with the first session and adjust from there based on how your skin responds. Some providers even mix the two — using one formula in certain areas and the other elsewhere — rather than committing to a single product across your whole face. Here's what to expect: your provider will usually walk through both options with you before recommending one.
How Many Sessions Will You Need?
Rejuran, in either form, isn't a one-and-done treatment. Most protocols call for a series of sessions spaced two to four weeks apart, with results building gradually rather than showing up all at once. Your provider will typically recommend a specific number of sessions based on where your skin is starting from and how it responds along the way.
Cost varies quite a bit depending on the clinic, the number of sessions, and whether you're combining PN with HA, so it's worth asking your provider for a plan tailored to your skin rather than assuming one price fits everyone.

Recovery Timeline: What's Normal (and What's Not)
In the days after a Rejuran session, it's common to notice a few mild reactions. Most settle on their own without any special treatment.
- Redness and mild swelling at the injection site: Usually settles within one to three days.
- Small bumps you can feel under the skin: That's just the product before it fully disperses, and it typically smooths out within a few days.
- Light bruising: Usually fades within a week and is easy to cover with concealer.
- Mild tightness or a slight stinging sensation: Keeping the area moisturized usually helps this settle within a few days.
That said, a few signs mean it's time to check in with your provider rather than wait it out.
- Pain or swelling that keeps getting worse: This needs a follow-up with your provider.
- High fever, spreading redness, or noticeable heat at the site: This can point to infection — seek medical care right away.
- A firm lump that hasn't gone down after two weeks: Worth checking in on together with your provider.
- Hives or itchiness that keeps spreading: This could be an allergic reaction.
- Skin turning noticeably pale or white at the injection site: Contact your provider immediately.
During recovery, it's a good idea to skip the sauna, intense workouts, and alcohol for a day or two, and to avoid rubbing the treated area. Keeping up with moisturizer and sunscreen tends to help your skin's texture settle in faster.
Side Effects & Risks
Like most injectable treatments, Rejuran carries a small risk of infection, allergic reaction, or a lump that takes longer than expected to resolve. Redness and swelling are common and usually settle within a few days — if they worsen or spread, contact your provider right away rather than waiting to see if it clears on its own.
Individual results vary, and how your skin responds depends on factors your provider will walk you through during a consultation, including your skin type, how many sessions you commit to, and how closely you follow aftercare instructions. This article is meant as general information, not a substitute for a conversation with the provider who's actually looking at your skin.
The Bottom Line
- Original Rejuran and Rejuran HB share the same PN core, but HB adds hyaluronic acid for hydration and mild, immediate volume.
- Texture and elasticity concerns tend to point toward original Rejuran; dryness and fine lines tend to point toward HB.
- Both are done as a series of sessions rather than a single visit, and results build gradually over weeks.
- Most reactions in the days after treatment are mild and short-lived, but watch for red flags like worsening pain, fever, or spreading redness.
Like any procedure, it comes with trade-offs, and no injectable is one-size-fits-all. Ultimately, the choice depends on your skin, your goals, and your budget. If you're considering Rejuran or Rejuran HB, a consultation is the best way to find out what actually fits you.

Frequently Asked Questions
Q1. Is Rejuran HB better than regular Rejuran?
Not necessarily better — just different. HB adds hyaluronic acid for hydration and a bit of immediate plumpness, while original Rejuran keeps the focus on repair and texture. Which one's the better fit really depends on what your skin needs, so it's worth discussing both with your provider.
Q2. How many sessions does it take to see results?
Most people go through a series of sessions spaced two to four weeks apart rather than a single visit. Results tend to build gradually across that series, so your provider will usually recommend finishing the full course before judging the outcome.
Q3. Is it normal to feel small bumps after a Rejuran session?
Yes, that's common right after injection, as the product hasn't fully dispersed yet. It typically smooths out within a few days on its own. If a firm lump is still there after two weeks, check in with the provider who treated you.
Q4. When can I wear makeup after treatment?
Most people can wear makeup starting the next day, though it's worth waiting a bit longer if there are visible injection marks. On treatment day, focus on moisturizer and sunscreen, keep your routine simple with low-irritation products, and avoid rubbing the treated area.
