Polynucleotide Contraindications: Ensuring Safe Aesthetic Treatment
Understanding polynucleotide contraindications is essential for safe and effective aesthetic treatment. These are specific health conditions or medical history factors that may prevent or require caution with polynucleotide injections. Key absolute contraindications include pregnancy, breastfeeding, active skin infections, and known allergies to product components like fish. Relative contraindications, such as certain autoimmune diseases, necessitate a detailed medical assessment. Disclosing a comprehensive medical history is crucial for determining polynucleotide safety and suitability, ensuring patient well-being.
Rejuva London, a doctor-led aesthetic clinic on Harley Street, prioritizes patient safety through rigorous medical consultations. Their expert approach ensures that all polynucleotide treatments are precisely tailored to individual health profiles, minimizing risks and optimizing regenerative outcomes.

What Are Polynucleotide Contraindications?
A contraindication is a condition where a procedure should not be used because it may be harmful. For polynucleotide therapy, these are health or medical history factors that increase the risk of adverse effects and help determine who is an ideal candidate for polynucleotide injections.
Primary absolute contraindications for polynucleotide treatment include:
- Pregnancy or breastfeeding
- Active skin infection or inflammation in the treatment area
- Known allergy to the product’s components (e.g., fish/salmon)
- Severe, uncontrolled systemic diseases
Absolute vs. Relative Contraindications Explained
Absolute contraindications are conditions where treatment must not be performed due to a high risk of serious harm. Relative contraindications mean caution is required; treatment may be possible, but a qualified doctor must weigh the benefits against the potential risks.
Absolute Contraindications
Pregnancy and Breastfeeding: Prioritizing Maternal and Infant Safety
No clinical data exists on the effects of polynucleotide injections during pregnancy or breastfeeding, so treatment is strictly contraindicated to avoid any potential risk to the mother, foetus, or nursing infant. Treatment can be considered after breastfeeding is finished.
Active Skin Infections or Inflammatory Conditions in the Treatment Area
Injecting into an area with an active infection or severe inflammation can worsen the condition, spread the infection, and compromise healing. This includes bacterial (impetigo), viral (active herpes simplex), or fungal infections, and severe flare-ups of eczema, psoriasis, or active cystic acne. The skin must be healthy and intact before treatment.
Your Medical History and The Rejuva London Consultation
A pre-treatment consultation is a critical safety step where a medical professional assesses your health, discusses your goals, and identifies potential polynucleotide contraindications.
The Doctor-Led Difference: Precision in Patient Safety Assessment
At Rejuva London, only medical doctors perform injectable procedures. This policy ensures the person assessing your suitability has the medical training to understand complex health histories. Our founder, Dr. Kristy Lau, a graduate of Imperial College London, has instilled a culture of rigorous medical assessment. A doctor can interpret how a past illness or current medication might impact an aesthetic treatment, an insight crucial for patient safety.
What to Disclose: Beyond the Obvious for Your Safety
Be prepared to discuss the following with your doctor:
- All past and present medical conditions, including autoimmune disorders, skin conditions, and bleeding disorders.
- A complete list of all prescription medications, over-the-counter drugs, and dietary supplements you are taking.
- Any known allergies, including foods, medications, or environmental allergens.
- Your history with past aesthetic treatments, both injectable and non-injectable, and how your body responded.
- Any recent illnesses or upcoming surgeries.
The Doctor-Led Approach to Safety
Patient safety extends beyond the initial consultation to include treatment planning, product selection, and post-treatment care protocols to minimize risks.
Rigorous Screening and Personalized Treatment Planning
After a thorough consultation, a personalized treatment plan is developed. This plan details specific precautions if any relative contraindications are present. At Rejuva London, we use Plinest, a purified, medical-grade polynucleotide product with a strong safety record. This choice is part of our risk-management strategy to ensure product purity and safety.
Managing Potential Risks and Post-Treatment Care
Minor side effects like swelling, redness, or bruising can occur. A doctor-led clinic is equipped to manage these outcomes and differentiate them from rare complications. You will receive clear aftercare instructions. Our clinical protocols, from skin preparation to post-injection care, are designed to maximize safety and deliver consistent results.

Frequently Asked Questions
What are the main polynucleotide contraindications to be aware of?
The primary polynucleotide contraindications include pregnancy, breastfeeding, active skin infections or inflammation in the treatment area, and known severe allergies to the product’s components. A full medical history must be discussed with your doctor during your consultation to ensure this regenerative treatment is safe and appropriate for you.
Is a severe fish allergy one of the key polynucleotide contraindications?
Yes, this is a critical point to discuss with your doctor. Although medical-grade polynucleotides are highly purified to remove allergenic proteins, a history of severe fish or seafood allergy is often considered one of the key polynucleotide contraindications. Your doctor will perform a detailed risk assessment based on your specific allergy history.
Can I have polynucleotides if I have an autoimmune disease?
This requires careful medical evaluation by a qualified doctor. While treatment may be possible for certain stable autoimmune conditions, an active or uncontrolled autoimmune disease is a significant reason to avoid this therapy. Patient safety is the absolute priority, and a thorough assessment is essential.
Why must I disclose all medications when discussing polynucleotide contraindications?
Disclosing all medications is vital for your safety, as it helps identify potential polynucleotide contraindications or risks. For instance, blood-thinning medications like aspirin or warfarin can significantly increase the risk of bruising at the injection sites. Your doctor needs this information to provide correct pre-treatment advice and ensure a safe procedure.
What happens if I have a condition that prevents treatment?
If you have a firm contraindication for polynucleotide therapy, our doctors will prioritise your safety and will not proceed with the treatment. They will explain the reasoning clearly and can then discuss alternative, safer regenerative treatments that are suitable for your specific medical profile and aesthetic goals.
How can I determine if I am a suitable candidate for polynucleotide treatment?
The best way to determine your suitability is to schedule a comprehensive consultation with a medical doctor. At our Harley Street clinic, a doctor will thoroughly assess your medical history and skin to confirm if polynucleotide therapy is safe for you. Book a polynucleotide consultation to have your questions answered by an expert.
