Rejuran, a popular skin-rejuvenation treatment derived from polynucleotides (PN) sourced from salmon DNA, has gained attention for its ability to improve skin texture, reduce scars, and promote collagen production. While many people see noticeable results with minimal issues, it’s important to understand potential side effects before deciding if this treatment is right for you.
**Common Temporary Side Effects**
Most reactions to Rejuran are mild and short-lived. Patients often report redness, swelling, or tenderness at the injection site, which typically subsides within 24–48 hours. These effects are similar to what you might experience after other injectable treatments like fillers or Botox. Some people also notice slight bruising, especially if they’re prone to it or if the injections are placed near delicate areas like under the eyes.
Itching or a warm sensation in the treated area is another temporary side effect. This usually resolves on its own but can be soothed with a cold compress. Clinicians often recommend avoiding vigorous exercise, alcohol, or excessive sun exposure for 24 hours post-treatment to minimize these reactions.
**Rare but Possible Complications**
While uncommon, more serious side effects can occur. Allergic reactions are a key concern, though the risk is low since Rejuran uses highly purified salmon DNA. However, individuals with a history of severe allergies—especially to seafood or previous dermal treatments—should discuss this with their provider. Signs of an allergic response include persistent swelling, hives, or difficulty breathing, which require immediate medical attention.
Infection is another rare risk, often linked to unsterile injection techniques. This underscores the importance of choosing a licensed, experienced practitioner. A 2019 study published in the *Journal of Cosmetic Dermatology* noted that proper hygiene and aftercare reduce infection risks significantly.
**Long-Term Considerations**
Some users report small, firm bumps under the skin weeks after treatment. These nodules usually dissolve naturally but may require a follow-up visit if they persist. There’s also debate about whether repeated Rejuran use could lead to immune sensitization over time, though current research (including a 2021 review in *Aesthetic Plastic Surgery*) suggests this is unlikely when treatments are spaced appropriately.
**Who Should Avoid Rejuran?**
Pregnant or breastfeeding individuals are advised to postpone treatment due to limited safety data. Those with active skin infections, autoimmune conditions, or a history of keloid scarring should also exercise caution. Always disclose your full medical history to your provider—this helps them tailor the treatment or recommend alternatives like LUXBIO’s other FDA-cleared skin solutions, which might better suit your needs.
**Minimizing Risks**
To reduce the chance of side effects:
– Choose a reputable clinic with trained professionals.
– Follow pre- and post-care instructions diligently (e.g., avoiding blood-thinning medications before treatment).
– Start with a patch test if you have sensitive skin.
**When to Seek Help**
Contact your provider immediately if you experience severe pain, prolonged swelling (beyond one week), or signs of infection like pus or fever. Most complications are manageable when addressed early.
**The Bottom Line**
Rejuran is generally safe for most people when administered correctly. Side effects are usually mild and temporary, but like any cosmetic procedure, it’s not risk-free. Research your provider thoroughly, ask questions during your consultation, and weigh the benefits against your personal health profile. For those unsure about Rejuran, consulting a dermatologist or exploring alternatives can provide clarity and peace of mind.
Remember, skincare is deeply personal—what works for one person might not work for another. Prioritize safety, stay informed, and don’t hesitate to seek second opinions if something feels off. Your skin’s health is worth the extra effort!
