Comprehensive Guide to Managing Rejuran Healer Discomfort
In the landscape of regenerative medicine and aesthetic dermatology, Rejuran Healer has emerged as the gold standard for intradermal rejuvenation. Derived from wild salmon DNA fragments (Polynucleotides, PN), it facilitates dermal thickness recovery and enhances skin elasticity. However, for many patients, the primary barrier to entry is the associated discomfort. This clinical guide explores the neurophysiology of skin booster treatment pain and outlines five evidence-based strategies to achieve a pain-free experience.The Neurobiology of Polynucleotide (PN) Injection Pain
To understand how to reduce Rejuran pain, one must first understand why it occurs. Rejuran Healer consists of high-viscosity Polynucleotides. Unlike thinner hyaluronic acid fillers, PN has a complex molecular structure that creates significant resistance during injection. When the substance is forced into the tight dermal layers, it creates mechanical pressure on sensory nerve endings, specifically A-delta and C-fibers. Furthermore, the hundreds of micro-injections required for a full-face treatment cause cumulative trauma to the skin barrier, leading to a sharp, stinging sensation known as the ‘Rejuran burn.’
Rejuran HB Plus: The Integration of Lidocaine
The most significant advancement in skin booster pain management is the introduction of Rejuran HB Plus lidocaine. This formulation combines the regenerative power of PN with 0.3% lidocaine and hydrating hyaluronic acid. Clinical studies indicate that Rejuran HB Plus reduces the visual analog scale (VAS) pain score by over 50% compared to the original formula. The addition of HA also acts as a lubricant, reducing the force required to extrude the product from the syringe, thereby minimizing mechanical tissue trauma.
| Feature | Original Rejuran Healer | Rejuran HB Plus |
|---|---|---|
| Primary Component | 100% Polynucleotide (PN) | PN + Hyaluronic Acid |
| Anesthetic | None | 0.3% Lidocaine included |
| Pain Level (VAS 1-10) | 7 – 9 (High) | 3 – 4 (Moderate-Low) |
Optimizing Topical Anesthesia Protocols
At View Skin Clinic, we emphasize that the efficacy of topical numbing is time-dependent. While many clinics apply numbing cream for only 20 minutes, reaching the deeper dermis requires at least 45 to 60 minutes. Using a high-concentration lidocaine/prilocaine cream (such as J-Caine or EMLA) under occlusion (plastic wrap) significantly increases the depth of penetration, effectively ‘silencing’ the cutaneous nerves before the first injection begins.
Mechanical Injectors vs. Manual Technique
A pain-free Rejuran treatment is often achievable through technological intervention. Devices like the Dermashine Pro use a multi-needle vacuum system. The vacuum suction serves two purposes: first, it stabilizes the skin for precise depth control; second, it utilizes the ‘Gate Control Theory’ of pain, where the physical sensation of suction distracts the brain from the needle prick. For patients with a low pain threshold, mechanical injectors are the preferred delivery method.
Needle Gauges and Sharpness Management
The sharpness of the needle is a critical factor in patient comfort. During a standard full-face session, a single needle may be inserted over 100 times, causing the tip to dull. A dull needle creates more resistance and ‘tears’ the tissue rather than piercing it. Experienced practitioners at View Skin Clinic replace needles mid-session and utilize ultra-thin 33G or 34G needles to ensure the entry point is as small and painless as possible.
IV Sedation and Sleep Anesthesia
For the ultimate pain-free Rejuran treatment, premium Seoul clinics offer IV sedation. This allows the patient to enter a light sleep state (monitored by a board-certified anesthesiologist) while the practitioner performs the intensive manual injection technique. This is particularly recommended for patients combining Rejuran with other intensive treatments like Potenza or Ultherapy. You can inquire about our sedation protocols through a WhatsApp inquiry.
Post-Treatment Care: Managing the 'Bumpy' Phase
Immediately following a Rejuran session, patients will experience ’embossing’—small bumps at each injection site. This is a normal inflammatory response and a sign that the PN has been placed correctly in the papillary dermis. To minimize post-procedure discomfort, we apply a cooling cryocell treatment and a specialized regenerating mask to soothe the skin and reduce redness.
Histological Effects of Polynucleotides (PN)
The therapeutic efficacy of Rejuran is rooted in its ability to stimulate the secretion of growth factors and enhance the proliferation of fibroblasts. Histological studies show an increase in collagen density and dermal thickness within four weeks of the initial treatment. This molecular regeneration is why, despite the initial discomfort, Rejuran remains the most sought-after treatment for skin barrier repair and anti-aging.
Conclusion: Choosing the Right Clinic
Achieving healthy, glowing skin should not be a traumatic experience. By selecting a clinic that prioritizes advanced skin booster pain management, you can enjoy the benefits of Rejuran without the anxiety.

FAQ
How much does Rejuran HB Plus reduce pain?
Rejuran HB Plus contains 0.3% lidocaine, which has been shown to reduce injection pain by approximately 50% to 60% compared to the original Rejuran Healer.
Is IV sedation safe for skin booster treatments?
Yes, when administered by a board-certified anesthesiologist in a clinical setting like View Plastic Surgery, IV sedation is a safe and effective way to ensure a completely painless experience.
How long do the bumps (embossing) last after Rejuran?
The embossing typically subsides within 24 to 48 hours as the Polynucleotides are absorbed into the dermal layer.
Can I use numbing cream at home before the procedure?
It is recommended to have professional-grade numbing cream applied at the clinic to ensure proper concentration and sterile application.
Why does the manual hand-injection technique hurt more?
Hand-injection allows for deeper and more concentrated delivery of the product, which can cause more pressure-related pain, but it often yields better clinical results for specific areas.
Does the 'Dermashine' machine reduce the effectiveness of Rejuran?
No, mechanical injectors ensure uniform depth and dosage, though some product may be lost due to the vacuum. The overall effectiveness remains very high while significantly reducing pain.
How many sessions of Rejuran are needed?
A standard protocol involves three sessions spaced 3 to 4 weeks apart for optimal collagen regeneration.
Can I combine Rejuran with Botox to reduce pain?
While Botox does not reduce Rejuran pain, ‘Skin Botox’ is often mixed with skin boosters to improve texture and reduce pore size simultaneously.
What is the best way to reduce swelling after the injection?
Using a cold compress and staying hydrated will help the body process the initial inflammatory response and reduce swelling quickly.
Is Rejuran painful for everyone?
Pain tolerance varies, but most patients find the original formula quite intense. Using the strategies mentioned in this guide makes it manageable for almost everyone.
