Rejuran Healer vs. HB Plus: Which Hurts Less?
Rejuran Healer and Rejuran HB Plus both use polynucleotide to support the skin's repair process, but HB Plus adds hyaluronic acid and a numbing ingredient that makes the injections easier to sit through. Here's how the two compare on ingredients, pain, and results.
If you've been comparing Rejuran Healer and Rejuran HB Plus, you're not alone — the two names show up together so often that it's easy to assume they're interchangeable. They're not. Both treatments are built around the same core ingredient, but HB Plus adds two things Healer doesn't: extra hydration and a numbing ingredient that changes how the injections actually feel. In this article, we'll cover what's really inside each formula, why one tends to hurt less than the other, how to match either option to your skin goals, and what to watch for once you get home.
What Are Rejuran Healer and HB Plus?
Both Healer and HB Plus belong to the Rejuran line, and both are built around polynucleotide (often shortened to PN) — a DNA fragment derived and purified from salmon. Once injected into the skin, PN doesn't fill space the way a traditional filler does. Instead, it holds onto water and appears to support the skin's own repair process, which is why providers usually describe the effect as a gradual improvement in texture rather than an instant plumping.
Rejuran Healer is the original formula: PN and little else. It's aimed squarely at overall skin quality — texture, fine lines, and elasticity. Rejuran HB Plus is a hybrid version that adds hyaluronic acid (HA) for hydration and lidocaine, a local anesthetic, to take the edge off the injections. Same base ingredient, different job description.
How Does Rejuran Actually Work?
Research on polynucleotide describes it as a long-chain molecule that binds water and appears to support tissue repair once it's introduced into the skin. One review notes that PN's chain structure lets it retain moisture while assisting the body's own repair mechanisms, which lines up with how providers talk about Rejuran in practice — it's less about adding volume and more about nudging the skin to do its own maintenance work.
During a session, PN is injected in small amounts across several points in the treatment area, sitting in the dermis rather than deeper tissue. That's part of why results build slowly: the skin needs time to respond to the material, and most providers plan for a series of sessions rather than a single visit.
Key Differences: Ingredients and Pain Level
On paper, the two formulas look close. In practice, the differences show up in two places: what the injection is meant to accomplish, and how much it stings while it's happening.
| Category | Rejuran Healer | Rejuran HB Plus |
|---|---|---|
| Core ingredient | Polynucleotide (PN) | PN + hyaluronic acid + lidocaine |
| Main focus | Texture and elasticity | Texture plus hydration |
| Pain level | Noticeable stinging | Milder, thanks to built-in numbing |
| Good fit for | Fine lines and elasticity concerns | Dryness plus a lower pain tolerance |
The pain difference comes down to lidocaine. HB Plus has it built into the formula, so the numbing effect kicks in as the product goes in. Healer skips it, which is why providers often apply a topical numbing cream before injecting instead. That helps, but it's not quite the same as having anesthetic mixed directly into the product. To be clear, neither option is billed as pain-free — it's not entirely pain-free, but HB Plus is simply the milder of the two for most people. Pain tolerance is personal, and where the injections land also plays a role.
What to Expect: Timeline and Results
Right after a session, it's normal to see small raised bumps where the product was injected. Those typically flatten out within a day or two. Underneath, though, change happens more slowly. Providers usually recommend a series of sessions spaced several weeks apart, with texture and hydration building gradually rather than showing up all at once.
Because Rejuran works by supporting the skin's own repair process rather than adding volume all at once, don't expect a dramatic before-and-after from a single visit. Most people notice smoother, better-hydrated skin emerging over the weeks following each session, and that improvement tends to compound as you complete the recommended series. Individual results vary based on skin condition, session spacing, and how your body responds to treatment.
Side Effects and Risks
Because Rejuran is injected across many shallow points, some reaction in the days right after treatment is common. Most of it settles on its own without extra care.
- Small bumps at injection sites — usually flatten within a day or two
- Mild redness or stinging — common, and typically fades quickly
- Light bruising — can appear at injection points and usually clears within one to two weeks
While your skin settles, it's best to skip saunas, steam rooms, intense workouts, and alcohol for a few days, and to stay consistent with moisturizer and sunscreen. That said, a few signs mean it's time to check in with your provider rather than wait it out.
- Swelling or pain that keeps getting worse instead of improving
- Warmth paired with redness that's spreading — this can point to infection, so seek medical care right away
- Firm lumps at injection sites that don't soften over time

Which One Should You Choose?
The decision usually comes down to what you're trying to fix and how much the injections themselves bother you. If your main concerns are texture, fine lines, and elasticity, Healer's straightforward PN formula does the job. If you'd rather add hydration at the same time, or if needle sensitivity is a real factor for you, HB Plus's built-in numbing and added hyaluronic acid make it the more comfortable pick.
Neither treatment is a one-visit fix — both call for a short series of sessions to see the full effect, so think of the choice as picking a starting point rather than a final answer. Some people even move between the two over time as their skin's needs shift. BeautyStone, a dermatology clinic in Seoul's Hapjeong neighborhood, typically starts by identifying whether texture, hydration, or elasticity is the priority before recommending which formula — and how many sessions — makes sense.
The Bottom Line
Rejuran Healer and HB Plus share the same core ingredient, but they're built for slightly different jobs. Healer keeps things simple and focuses on texture and elasticity. HB Plus adds hydration and, more importantly for a lot of people, a numbing ingredient that makes the injections noticeably easier to sit through. Like any injectable treatment, both come with some downtime and a small list of reactions worth watching for.
Ultimately, the right choice depends on your skin, your pain tolerance, and what you're hoping to see change. If you're considering Rejuran, a consultation is the best way to find out what fits you — BeautyStone is a dermatology clinic in Seoul's Hapjeong area, and current offers are listed at /en/promotion.
Frequently Asked Questions
Q1. Does Rejuran HB Plus really hurt less than Healer?
Yes, most people report less stinging with HB Plus because it contains a built-in numbing ingredient, lidocaine. It's not entirely pain-free, but the injections tend to feel noticeably milder than with Healer, which typically relies on a topical numbing cream applied beforehand instead.
Q2. How many Rejuran sessions will I need?
Rejuran isn't a one-and-done treatment. Most providers recommend a series of sessions spaced a few weeks apart, with results building gradually over that course. Your provider will map out a plan based on your skin and goals at your first visit.
Q3. Can I get Rejuran Healer and HB Plus together?
Some providers use both at different points, depending on what you're trying to address. Whether to combine them, and in what order, depends on your skin condition and recovery, so it's worth discussing with your provider rather than deciding on your own. If it's your first time, starting with one option and seeing how your skin responds is often the safer route.
Q4. Can I wear makeup right after treatment?
It's best to skip makeup on the day of your treatment since the injection sites need time to settle. Most people can go back to their normal routine the next day, but recovery speed varies from person to person, so ask your provider for guidance specific to your skin.
