What to Expect During a Rejuran Treatment Session
During a Rejuran treatment session, you can expect a medical procedure that typically lasts between 30 to 60 minutes, involving a series of micro-injections into the targeted area of the skin, such as the face, neck, or décolletage. The process is designed to be minimally invasive with the primary goal of stimulating your skin's natural healing and collagen production from within. The session is generally well-tolerated, with most patients describing the sensation as a slight prickling or stinging, often mitigated by the application of a topical numbing cream beforehand. The entire experience, from consultation to aftercare instructions, is structured to be efficient and focused on achieving long-term skin rejuvenation.
The Pre-Treatment Consultation: Laying the Groundwork
Your journey doesn't start with the injection; it begins with a thorough consultation with a qualified practitioner. This is a critical step where your medical history, skin concerns, and aesthetic goals are discussed in detail. The practitioner will assess your skin type, the severity of issues like fine lines, acne scars, or overall skin laxity, and determine if you are a suitable candidate. This is the time to ask every question you have. Be prepared to discuss:
- Your Medical History: Allergies, current medications (especially blood thinners like aspirin or warfarin), and any history of keloid scarring or autoimmune diseases.
- Skin Conditions: Any active skin infections, cold sores, or inflammatory conditions like eczema or psoriasis in the treatment area.
- Expectations: A realistic understanding of what Rejuran can achieve. It's a regenerative treatment, not a filler; results develop over weeks as your skin heals itself.
The practitioner will also explain the science behind the treatment. Rejuran is based on Polynucleotides (PN), which are chains of DNA fragments derived from purified salmon DNA. These PNs are highly biocompatible and act as signaling molecules to reduce inflammation and promote fibroblast activity—the cells responsible for producing collagen, elastin, and hyaluronic acid. You'll likely sign a consent form acknowledging your understanding of the procedure, potential side effects, and the aftercare protocol.
Step-by-Step: The Treatment Session Unfolded
On the day of your appointment, you'll be seated in a clinical treatment chair. The environment should be clean, professional, and reassuring. Here is a detailed, minute-by-minute breakdown of what typically occurs:
| Time Elapsed | Phase | Actions & Sensations |
|---|---|---|
| 0-15 Minutes | Preparation & Cleansing | The practitioner will thoroughly cleanse the treatment area with an antiseptic solution to eliminate any surface bacteria and reduce the risk of infection. If a topical numbing cream wasn't applied earlier, it will be applied now and needs about 15-20 minutes to take full effect. You'll feel a cool sensation from the cream. |
| 15-45 Minutes | The Injection Process | Once the area is numb, the actual injection process begins. The practitioner will use a very fine-gauge needle (often a 30G or 31G) or a specialized micro-needling device to deposit the Rejuran solution intradermally (into the middle layer of the skin). The technique is precise, involving multiple tiny injections in a grid-like pattern across the target area. You will feel a series of quick, sharp pricks. The discomfort is generally mild, similar to a mosquito bite. The number of injections depends on the size of the area; a full face treatment can involve 100-200 micro-injections. |
| 45-60 Minutes | Immediate Aftermath & Soothing | Immediately after the injections, it's normal for the skin to appear red, slightly swollen, and have tiny raised bumps (welts) at each injection point—this is a common reaction known as a "wheel" and indicates the solution has been properly placed. The practitioner will often gently massage the area to ensure even distribution of the product. A calming serum or a cold compress may be applied to soothe the skin and reduce redness. |
Immediate Post-Treatment Appearance and Sensations
Don't be alarmed by how your skin looks right after the session. The immediate side effects are temporary and a sign that the regenerative process has been initiated. Here’s what is considered normal:
- Redness (Erythema): Similar to a mild sunburn, this can last from a few hours up to 24-48 hours.
- Swelling (Edema): Particularly around areas with thinner skin, like the under-eyes, swelling can be more noticeable. It usually subsides significantly within the first day.
- Bumps/Welts: The small raised areas at injection sites typically flatten within a few hours.
- Minor Bruising: Small pin-point bruises may appear, especially if you are prone to bruising or on certain medications. These usually fade within 3-7 days.
- Tenderness: The skin may feel tender to the touch for a day or two.
You will be able to return to most of your daily activities immediately, but you'll need to avoid strenuous exercise, excessive heat (saunas, hot yoga), and direct sun exposure for at least 24-48 hours to minimize swelling and the risk of complications.
The Science of Healing: What's Happening Beneath the Skin?
While the injection session itself is quick, the real work begins underneath the surface in the days and weeks that follow. The polynucleotides in Rejuran don't just sit there; they actively interact with your skin cells. The biological process can be broken down into phases:
- Inflammatory Phase (Days 1-3): The micro-injuries created by the needle trigger a controlled inflammatory response. The PNs work to modulate this inflammation, preventing it from becoming excessive while attracting fibroblasts to the area.
- Proliferative Phase (Weeks 1-4): This is the crucial rebuilding phase. The fibroblasts, stimulated by the PNs, start producing new collagen (Type I and III), elastin fibers, and hyaluronic acid. This process gradually improves skin density, elasticity, and hydration.
- Remodeling Phase (Months 1-6): The newly formed collagen matures and reorganizes itself into a stronger, more structured network. This is when you see the full effects of the treatment: smoother texture, reduced appearance of scars, and an overall firmer, more youthful complexion.
This is why practitioners emphasize that results are not instant. You might notice initial hydration and a "glow" within the first couple of weeks, but the significant structural improvements become most apparent after one to three months.
Tailoring the Treatment: Techniques and Variations
Not all Rejuran sessions are identical. A skilled practitioner will tailor the technique based on your specific concerns. The depth of injection, the pattern, and even the specific Rejuran product used can be customized. For example:
- For Acne Scarring: The practitioner may use a cross-hatching technique, injecting directly into the base of depressed scars to stimulate tissue regeneration from below.
- For Overall Rejuvenation: A broader, evenly spaced pattern across the entire cheek, forehead, or jawline is used to improve general skin quality and elasticity.
- For Dark Circles: A very superficial injection technique is employed in the delicate under-eye area to improve skin thickness and reduce the appearance of bluish tints.
Furthermore, Rejuran is sometimes combined with other treatments like hyaluronic acid fillers (for immediate volume and long-term regeneration) or laser therapies (to enhance collagen stimulation) in a single session. This combination approach should always be discussed during your consultation.
Navigating Potential Risks and Ensuring Safety
While Rejuran is considered very safe due to its high biocompatibility, no medical procedure is entirely without risk. Being informed is key to a safe experience. The most common side effects are the temporary ones mentioned earlier (redness, swelling). However, more uncommon risks include:
- Infection: The risk is low if proper sterile techniques are used, but it's a possibility with any injection.
- Allergic Reaction: Although rare, given the high purity of the salmon-sourced DNA, an allergic response is possible. This is why a patch test may be recommended for individuals with known severe allergies.
- Nodule Formation: If the product is injected too superficially, small, palpable nodules can form. These often resolve on their own but may require medical attention.
The single most important factor in minimizing risks and maximizing results is choosing a qualified, experienced medical professional—a certified dermatologist or plastic surgeon—who has a deep understanding of facial anatomy and injection techniques. Do not prioritize cost over expertise.
The Roadmap After Your Session: Crucial Aftercare
What you do after the treatment is just as important as the treatment itself. Your practitioner will provide you with specific instructions, but general guidelines include:
- First 24 Hours: Avoid touching the treated area, wear a wide-brimmed hat, and apply a gentle, physical sunscreen (zinc oxide/titanium dioxide). Do not apply makeup to allow the skin to breathe and heal.
- First Week: Use only mild, non-abrasive skincare products. Avoid active ingredients like retinoids, alpha-hydroxy acids (AHAs), and vitamin C, which can be irritating. Sleep on your back if possible to avoid pressure on the face.
- Long-Term: Maintain a consistent skincare routine focused on hydration and sun protection to protect and prolong your results. A series of treatments (usually 3 sessions spaced 4 weeks apart) is often recommended for optimal, long-lasting results that can persist for 6-12 months or more.
