Polynucleotide Treatment: Advanced Skin Regeneration for Natural Rejuvenation

Are you frustrated with skin treatments that promise dramatic results but deliver disappointment? Many patients come to us feeling self-conscious about signs of aging, tired of ineffective products, and concerned about invasive procedures that might leave them looking “overdone.” Polynucleotide (PN) treatment offers a revolutionary solution.

This advanced regenerative therapy uses purified DNA fragments to activate your body’s natural healing mechanisms at the cellular level. Unlike traditional fillers that simply add volume, PN injections stimulate collagen production, enhance hydration, and improve overall skin quality for results that look completely natural.

The treatment process is straightforward—a quick 30-45 minute session with minimal discomfort and virtually no downtime. You’ll notice immediate hydration effects, with progressive improvement in skin texture, firmness, and radiance developing over 2-4 weeks as your skin’s regenerative processes activate.

At Rejuva London, all polynucleotide treatments are performed exclusively by our experienced doctor, ensuring precise application and personalized care for truly balanced, natural-looking rejuvenation that enhances—rather than alters—your appearance.

What Are Polynucleotide Treatments? Understanding PN Therapy

As a medical aesthetic specialist with over 10 years of experience, I’ve witnessed numerous innovations in skin rejuvenation, but polynucleotide treatment stands out as truly revolutionary. Polynucleotide (PN) therapy represents the cutting edge of regenerative aesthetics, utilising DNA fragments derived from salmon sperm DNA to stimulate profound skin regeneration at the cellular level.

Polynucleotides are essentially chains of nucleotides—the building blocks of DNA—that have been purified and processed into injectable formulations. When introduced to the skin, these DNA fragments work as biostimulators, triggering the body’s natural healing mechanisms and cellular renewal processes. Unlike traditional fillers that simply add volume, PN therapy addresses the fundamental causes of skin ageing by enhancing tissue regeneration.

At Rejuva London on Harley Street, we’ve incorporated polynucleotide treatment into our comprehensive skin rejuvenation protocols because of its remarkable ability to improve skin quality without altering facial features. This makes it ideal for patients seeking natural-looking improvements in skin texture, elasticity and overall vitality without appearing “done.”

How Polynucleotide Injections Work to Regenerate Skin

The science behind polynucleotide injections is fascinating and represents a significant advancement in skin regeneration technology. When I administer PN therapy to my patients at our Harley Street clinic, I’m essentially delivering highly purified DNA fragments directly to the areas requiring rejuvenation. These polynucleotides work through several complementary mechanisms to transform skin health from within.

Think of polynucleotides as cellular architects. Upon injection, they immediately begin attracting water molecules due to their hydrophilic properties, providing instant hydration to the skin tissues. This initial hydration effect creates a more favourable environment for cellular function. However, the true magic happens in the days and weeks following treatment, as the polynucleotides activate fibroblasts—the cells responsible for producing collagen, elastin and hyaluronic acid.

The DNA fragments in PN injections also enhance microcirculation, ensuring better oxygen and nutrient delivery to skin cells while promoting the removal of metabolic waste products. Additionally, they provide antioxidant protection against free radical damage and stimulate the production of growth factors that further accelerate tissue repair and regeneration.

What makes polynucleotide skin repair particularly remarkable is its ability to work with your body’s natural processes rather than simply masking signs of ageing. This results in gradual, progressive improvements that appear entirely natural—a cornerstone of our doctor-led approach at Rejuva London.

Key Benefits of PN Therapy for Skin Rejuvenation

In my extensive clinical experience treating over 20,000 patients, I’ve observed remarkable benefits from polynucleotide anti-aging treatments. The comprehensive rejuvenation effects of PN therapy make it one of our most versatile and effective skin regeneration options at Rejuva London.

The primary benefits of polynucleotide treatment include:

  • Enhanced Skin Hydration: PN injections dramatically improve moisture retention within the dermis, creating a plumper, more radiant complexion.
  • Increased Collagen Production: By stimulating fibroblast activity, polynucleotides trigger natural collagen synthesis, improving skin firmness and elasticity.
  • Improved Skin Texture: Patients consistently report smoother, more refined skin texture with reduced roughness and pore visibility.
  • Accelerated Healing: The DNA repair properties make PN therapy excellent for addressing scarring, including acne scars and surgical scars.
  • Reduced Fine Lines: The combination of hydration and collagen stimulation visibly diminishes fine lines and prevents their formation.
  • Enhanced Skin Luminosity: Improved cellular function and microcirculation restore the natural glow often lost with ageing.

What particularly impresses me about polynucleotide skin regeneration is its versatility across different skin types and concerns. Whether addressing photoageing, dehydration, loss of elasticity, or dullness, PN therapy delivers consistent improvements without the downtime associated with more aggressive treatments.

PN vs PRP: Understanding Different DNA Repair Treatments

As a medical professional specialising in advanced skin treatments, I’m often asked about the differences between polynucleotide therapy and platelet-rich plasma (PRP). While both are regenerative treatments that stimulate the body’s natural healing processes, they work through distinctly different mechanisms and offer unique benefits.

FeaturePolynucleotide (PN) TherapyPlatelet-Rich Plasma (PRP)
SourcePurified DNA fragments from salmon spermConcentrated platelets from patient’s own blood
PreparationReady-to-use pharmaceutical productRequires blood draw and processing
Primary ActionDirect DNA repair and fibroblast stimulationGrowth factor release from platelets
Treatment TimeTypically 30-45 minutes60-90 minutes including blood processing
ConsistencyStandardised formulation with predictable resultsResults may vary based on patient’s platelet quality

At Rejuva London, we offer both treatments and sometimes combine them for enhanced results. While PRP harnesses your body’s own growth factors, polynucleotide injectable treatment provides a more standardised approach with consistent concentrations of active ingredients. For patients seeking skin texture improvement and overall rejuvenation, PN therapy often provides more predictable outcomes with less variability between sessions.

The choice between these DNA fragment treatments depends on your specific skin concerns, preferences, and how your skin responds to different regenerative approaches—something we carefully assess during your consultation at our Harley Street clinic.

The Polynucleotide Treatment Process: What to Expect

At Rejuva London, all polynucleotide facial treatments follow our doctor-led only protocol, ensuring the highest standards of safety and efficacy. When you visit our Harley Street clinic for PN therapy, here’s what you can expect during your treatment journey:

Before Your Treatment

Your experience begins with a comprehensive consultation where I personally assess your skin condition, discuss your aesthetic goals, and determine if polynucleotide treatment is appropriate for your needs. I’ll explain the procedure in detail, answer any questions, and create a customised treatment plan tailored to your specific concerns.

During Your PN Treatment Session

On the day of treatment, we begin by thoroughly cleansing your skin and applying a topical anaesthetic to ensure your comfort. Once the treatment area is numbed, I precisely inject the polynucleotide solution using either a fine needle or cannula technique, depending on the treatment area and your specific needs. The injections are strategically placed to ensure optimal distribution of the product for natural-looking results.

The entire procedure typically takes 30-45 minutes, depending on the treatment areas. Most patients report minimal discomfort, describing the sensation as a slight pressure or pinching feeling during the injections.

After Your Treatment

Following your polynucleotide treatment, you may experience some mild redness, swelling, or tenderness at the injection sites—all normal responses that typically subside within 24-48 hours. Unlike more aggressive treatments, PN therapy allows you to return to your normal activities immediately, making it truly a “lunchtime procedure.”

We provide detailed aftercare instructions to maximise your results, including avoiding intense heat, strenuous exercise, and alcohol consumption for 24 hours post-treatment.

How Long Do Polynucleotide Treatment Results Last?

One of the most appealing aspects of polynucleotide treatment is its progressive, long-lasting results. Based on my extensive clinical experience at Rejuva London, I’ve observed that the benefits of PN therapy unfold in distinct phases, with results continuing to improve over time.

The initial hydration effect becomes visible almost immediately after treatment, with patients noticing plumper, more radiant skin within the first 24-48 hours. However, the true transformative effects of polynucleotide skin regeneration develop gradually as the DNA fragments stimulate cellular renewal and collagen production.

Most patients observe significant improvements in skin quality, texture, and elasticity within 2-4 weeks after their first treatment. These results continue to enhance over the following months as new collagen forms and skin cells regenerate. For optimal outcomes, I typically recommend an initial series of 3-4 treatments spaced 3-4 weeks apart.

Once the desired results are achieved, the effects of polynucleotide treatment generally last 6-8 months, though this varies based on individual factors such as age, lifestyle, and skin condition. To maintain and enhance these results, I recommend maintenance treatments every 6 months as part of a comprehensive skin health regimen.

What’s particularly remarkable about PN therapy is that the results appear entirely natural—there’s no artificial or “overdone” appearance, just healthier, more vibrant skin that reflects your natural beauty. This aligns perfectly with our philosophy at Rejuva London, where we prioritise subtle, elegant rejuvenation over dramatic transformations.

Who Is a Good Candidate for Polynucleotide Injections?

As a medical professional with over three decades of experience, I’ve found that polynucleotide treatments offer remarkable versatility across different age groups and skin concerns. However, determining suitable candidates requires careful assessment, which we conduct during comprehensive consultations at our Harley Street clinic.

Ideal candidates for PN injectable treatment typically include:

  • Individuals with Early to Moderate Signs of Ageing: Those noticing fine lines, reduced elasticity, or dullness can benefit significantly from the regenerative properties of polynucleotides.
  • Patients Seeking Natural-Looking Improvements: If you prefer gradual, subtle enhancement rather than dramatic changes, PN therapy aligns perfectly with this goal.
  • Those with Dehydrated or Sun-Damaged Skin: The powerful hydrating and reparative effects make polynucleotides excellent for addressing photodamage and dehydration.
  • Individuals with Acne Scarring or Textural Issues: The collagen-stimulating properties help improve skin texture and reduce the appearance of scars.
  • Patients Looking for Preventative Treatment: Younger individuals (30s-40s) seeking to maintain skin quality and prevent signs of ageing.

Polynucleotide treatment is generally safe for most skin types and tones, with minimal risk of hyperpigmentation, making it suitable for diverse patient populations. However, PN therapy may not be appropriate for pregnant or breastfeeding women, individuals with autoimmune disorders, active skin infections, or those with known allergies to fish products.

During your consultation at Rejuva London, I personally evaluate your skin condition, medical history, and aesthetic goals to determine if polynucleotide treatment is the optimal approach for your specific needs. This doctor-led assessment ensures you receive the most appropriate and effective treatment plan.

Frequently Asked Questions

What are polynucleotides used for in skincare?

Polynucleotides in skincare are primarily used for skin regeneration, collagen stimulation, and deep hydration. These DNA fragments work as powerful biostimulators that trigger the body’s natural healing mechanisms at the cellular level. At Rejuva London, we use polynucleotide treatments to address multiple skin concerns including fine lines, loss of elasticity, dehydration, dullness, and even acne scarring. Unlike traditional fillers that simply add volume, PN therapy targets the fundamental causes of skin aging by enhancing tissue regeneration and improving overall skin quality.

How do polynucleotide injections work?

Polynucleotide injections work by delivering purified DNA fragments directly to the skin, where they activate multiple regenerative processes. First, they attract water molecules due to their hydrophilic properties, providing immediate hydration. Then, they stimulate fibroblasts to produce collagen, elastin, and hyaluronic acid—essential components for youthful skin. Additionally, polynucleotides enhance microcirculation, provide antioxidant protection, and promote the production of growth factors that accelerate tissue repair. This comprehensive approach creates gradual, natural-looking improvements in skin texture, firmness, and luminosity without altering facial features.

Are polynucleotide treatments safe?

Yes, polynucleotide treatments are considered very safe when administered by qualified medical professionals. The polynucleotides used in these treatments are highly purified, biocompatible, and undergo rigorous pharmaceutical processing to ensure safety. Side effects are typically minimal and temporary, including mild redness, swelling, or tenderness at injection sites that usually resolve within 24-48 hours. At Rejuva London, all our PN treatments follow strict doctor-led protocols, with myself personally performing all injections to ensure the highest safety standards. The treatment is contraindicated for pregnant or breastfeeding women, those with autoimmune disorders, active skin infections, or known allergies to fish products.

What is the difference between PN and PRP treatments?

The main difference between polynucleotide (PN) and platelet-rich plasma (PRP) treatments lies in their source, preparation, and mechanism of action. PN therapy uses standardized, purified DNA fragments derived from salmon sperm DNA that directly stimulate skin regeneration and are available as ready-to-use products. PRP, conversely, uses concentrated platelets from the patient’s own blood, requiring blood draw and processing before treatment, and works by releasing growth factors. PN treatments typically take 30-45 minutes with consistent formulations providing predictable results, while PRP takes 60-90 minutes with results varying based on the patient’s platelet quality. At Rejuva London, we sometimes combine both approaches for enhanced rejuvenation effects.

How long do polynucleotide treatment results last?

Polynucleotide treatment results typically last 6-8 months after completing the initial treatment series. The benefits develop in phases: immediate hydration effects appear within 24-48 hours, while significant improvements in skin quality, texture, and elasticity become noticeable within 2-4 weeks. For optimal outcomes, I recommend an initial series of 3-4 treatments spaced 3-4 weeks apart, followed by maintenance treatments every 6 months. The longevity of results varies based on individual factors including age, lifestyle, skin condition, and adherence to proper skincare routines. What’s particularly valuable about PN therapy is that it produces progressive, natural-looking improvements rather than dramatic, artificial changes.

Who is suitable for polynucleotide treatment?

Polynucleotide treatments are suitable for a wide range of individuals seeking skin regeneration and quality improvement. Ideal candidates include people with early to moderate signs of aging, those seeking natural-looking enhancements, individuals with dehydrated or sun-damaged skin, patients with textural issues or acne scarring, and younger individuals (30s-40s) interested in preventative skincare. PN therapy works well across most skin types and tones with minimal risk of hyperpigmentation. However, it’s not recommended for pregnant or breastfeeding women, those with autoimmune disorders, active skin infections, or known allergies to fish products. At Rejuva London, we conduct thorough consultations to determine if polynucleotide treatment aligns with your specific skin needs and aesthetic goals.
