Understanding Adverse Reactions to Rejuran: When to Seek Help
Rejuran is a polynucleotide-based injectable treatment designed to support skin repair, hydration, and regeneration. It is often used in delicate areas such as under the eyes, where it may help improve texture and fine lines. While generally well tolerated, Rejuran, like all injectable treatments, carries some risk of adverse reaction. Knowing what to expect and recognising warning signs early is essential for anyone considering or currently receiving this treatment.
What Is a Normal Response to Rejuran?
Following Rejuran treatment, some mild and temporary side effects are expected. These typically include:
Small raised bumps at the injection sites (commonly called "blebs")
Mild redness, swelling or sensitivity
Localised tenderness
Occasional light bruising
These effects usually resolve within a few days. Your practitioner will advise you on typical timelines based on the treatment area and your skin type.
When Reactions May Indicate a Problem
While uncommon, some patients may experience responses that go beyond the normal recovery process. These may include:
Persistent or increasing swelling beyond a few days
Redness, heat or pain that worsens over time
Itching, rash or hives near the injection site
Puffiness or tightness that interferes with vision (especially around the eyes)
Delayed flare-ups weeks after treatment
Any visual disturbance, severe discomfort or signs of infection
If any of these symptoms occur, it is important to contact your clinic promptly for a medical review.
Why Do Adverse Reactions Happen?
Adverse responses to Rejuran may be influenced by:
Skin sensitivity or underlying inflammatory conditions
Incorrect technique or placement too close to sensitive structures
Product-related sensitivity
Pre-existing allergies or autoimmune history
It is critical that all patients undergo a full medical consultation prior to treatment to assess suitability and risk factors.
