If you’re considering a Rejuran treatment, you need to know that it’s a multi-step medical procedure involving injections of polynucleotide (PN) to rejuvenate and repair your skin. The entire process, from the initial consultation to full recovery, can span several weeks, and understanding the high-density details of each phase is crucial for setting realistic expectations and achieving optimal results. This isn’t a quick lunchtime fix; it’s an investment in your skin’s health that requires careful planning and aftercare.
The Science Behind the Solution: What Exactly is Being Injected?
Before we dive into the procedure, it’s essential to grasp what Rejuran is. The key ingredient is highly purified Polynucleotides (PN) derived from salmon DNA. These are not live cells or genetic material; think of them as building blocks or signaling molecules. Their primary function is to stimulate your skin’s own regenerative processes. When injected, these PN fragments attract fibroblasts—the cells responsible for producing collagen, elastin, and hyaluronic acid. A 2019 study published in the Journal of Cosmetic Dermatology reported a mean increase of 35.7% in skin density after a series of PN treatments, as measured by ultrasound. This bio-stimulatory action is what differentiates Rejuran from simple dermal fillers that just add volume.
| Key Component | Source | Primary Action in the Skin |
|---|---|---|
| Polynucleotides (PN) | Purified Salmon DNA | Signals fibroblasts to produce new collagen, elastin, and hyaluronic acid. |
Phase 1: The Pre-Procedure Consultation and Assessment
This is the most critical step that many underestimate. A reputable practitioner will conduct a thorough 30 to 45-minute consultation. They will:
- Analyze your skin type and concerns (e.g., fine lines, acne scars, overall skin laxity).
- Review your medical history, including any allergies (especially to fish or antibiotics), current medications, and past cosmetic procedures.
- Discuss realistic outcomes. Rejuran is renowned for improving skin texture and elasticity, but it’s not a facelift. For moderate to severe acne scars, studies show an average improvement of 30-50% after a full treatment series, but complete eradication is unlikely.
- Create a customized treatment plan. The standard protocol often involves 3 sessions spaced 4 weeks apart, but this can vary based on individual needs.
- Provide pre-care instructions. You’ll typically be advised to avoid blood-thinning medications (like aspirin or ibuprofen), alcohol, and certain supplements (Vitamin E, Ginkgo Biloba) for at least 5-7 days before treatment to minimize bruising.
Phase 2: The Procedure Day – A Step-by-Step Walkthrough
On the day of your appointment, the entire process usually takes about 60 to 90 minutes. Here’s what happens minute by minute:
- Cleansing and Numbing (20-30 minutes): Your face will be meticulously cleansed with an antiseptic solution. A topical numbing cream is then applied and left on for about 20-30 minutes to ensure comfort during the injections.
- Reconstitution of the Product (5 minutes): The Rejuran healer comes as a lyophilized (freeze-dried) powder in a vial. The clinician will mix it with a sterile saline solution to create an injectable liquid.
- The Injection Process (20-40 minutes): Using a very fine needle or a specialized microcannula, the practitioner will perform multiple micro-injections into the targeted areas of the dermis—the skin’s middle layer. The technique is crucial. For overall skin rejuvenation, a series of superficial injections are made across the entire face. For deeper scars, the practitioner may use a cross-hatching or tunneling technique to break up fibrous tissue and deposit the PN beneath the scar. You might feel a slight prickling or pressure sensation, but the numbing cream makes it very manageable.
- Immediate Aftermath (5 minutes): Right after the injections, it’s normal to see small raised bumps (welts) and mild redness, which usually subside within a few hours. The practitioner may apply a soothing gel or a LED light therapy session to calm the skin.
Phase 3: The Immediate Recovery (First 24-72 Hours)
This is the period where you need to be most diligent. Your skin is in a prime state for healing, and following instructions is non-negotiable.
- Redness and Swelling: Expect the treated area to look like a mild sunburn. This typically resolves within 12-24 hours. Swelling is usually minimal but can be more pronounced around the eyes or if a cannula was used.
- Bruising: Some minor bruising at the injection sites is possible, especially if you are prone to it. This can last from 3 to 7 days.
- Do’s and Don’ts:
- DO gently apply a cold compress (not ice directly) for 10-minute intervals to reduce swelling.
- DO keep the skin clean and use a gentle, non-active cleanser.
- DO sleep on your back with an extra pillow to minimize swelling.
- DON’T exercise, sweat heavily, or expose your face to extreme heat (saunas, hot yoga) for at least 24-48 hours.
- DON’T rub, scratch, or apply any makeup for at least 12 hours.
Phase 4: The First Week and Beyond – The Regenerative Timeline
This is where the magic starts to happen internally, even if the visible changes are subtle. The polynucleotides are getting to work, signaling your skin cells to ramp up production.
| Time Post-Treatment | What’s Happening Biologically | What You’ll Likely See and Feel |
|---|---|---|
| Days 3-7 | Initial inflammatory response subsides. Fibroblasts are activated and begin synthesizing new collagen precursors. | Skin returns to its normal appearance. Any minor bruising fades. You might notice a slight “glow” as hydration improves. |
| Weeks 2-4 | Collagen and elastin production is underway. This is a slow process; new collagen can take weeks to mature. | Skin texture begins to feel smoother. Fine lines may appear softened. This is the ideal window for your next session in a series. |
| 1-3 Months | Collagen remodelling peaks. The skin infrastructure becomes denser and more organized. | The most noticeable improvements become apparent: improved elasticity, reduction in pore size, and a more even skin tone. Acne scars begin to show significant softening. |
Maximizing Your Results: The Importance of a Full Series and Maintenance
One session of Rejuran is like a single workout—it helps, but it won’t transform your physique. The cumulative effect of a series is what delivers the dramatic, long-lasting results. Most clinics recommend an initial series of 3 treatments, each 4 weeks apart. This staggered approach provides a consistent signal to your fibroblasts, leading to progressive and sustained improvement. After this initial series, the results can last from 12 to 18 months. To maintain the effect, a single touch-up session every 12-18 months is typically advised. The longevity is highly individual and depends on factors like your age, skin condition, and lifestyle (sun exposure, smoking).
Potential Side Effects and How to Mitigate Risks
While Rejuran is considered very safe due to its biocompatibility, no injection is without risk. Being informed helps you identify normal reactions versus potential complications.
- Common and Temporary: Redness, swelling, bruising, tenderness, and itching at the injection site. These are expected and resolve quickly.
- Less Common: Small bumps or nodules can form if the product is injected too superficially. These usually dissolve on their own within a few weeks.
- Rare but Serious: Infection, allergic reaction, or vascular injury. The risk of these is significantly minimized by choosing an experienced, medically qualified practitioner who understands facial anatomy. Always ensure your provider uses a rejuran product from an authorized source.
The cost of Rejuran can vary widely based on your geographic location and the clinic’s expertise, but you can expect a per-session price ranging from $300 to $800. It’s an investment, and choosing the cheapest option is rarely the wisest path when it comes to injectables. Your skin’s health is paramount, and the skill of the injector is the single most important factor in achieving a safe and beautiful outcome.
