This guide details the key polynucleotide treatment areas and how this regenerative approach, administered by doctors, revitalizes skin at a cellular level. Polynucleotides improve skin quality, texture, and firmness in areas from the under-eye to the face and neck. At Rejuva London, our doctors apply these bio-stimulators with precision for natural, lasting rejuvenation, addressing concerns like fine lines, dark circles, rosacea, and crepey skin.

Understanding Polynucleotides: A Regenerative Approach to Skin Rejuvenation

Polynucleotides are injectable bio-stimulators that repair and regenerate skin tissue. Unlike traditional fillers, they do not add volume. They provide the building blocks for cellular renewal, leading to healthier, more resilient skin. The primary polynucleotide treatment areas include:

  • The Periorbital (Eye) Area: To address dark circles, fine lines, and thin, crepey skin.
  • The Full Face: For improving overall skin texture, firmness, and radiance.
  • The Neck and Décolletage: To combat horizontal lines (“tech neck”) and improve skin quality.
  • Specific Skin Concerns: Effective for managing rosacea, atrophic acne scars, and enlarged pores.

What Makes Polynucleotides Different from Traditional Fillers?

Hyaluronic acid (HA) fillers are gels that physically replace lost volume for immediate structural support. Polynucleotides are catalysts for regeneration. They signal fibroblasts to increase collagen and elastin production. This process results in gradual, natural improvements in skin density and elasticity, rather than simple augmentation.

The Science Behind Natural Skin Regeneration with Plinest

At Rejuva London, we use Plinest, a medical-grade product derived from highly purified salmon DNA fragments, chosen for its high biocompatibility with human DNA. When injected, these polynucleotide chains attract water molecules for hydration, act as antioxidants against free radical damage, and create an optimal environment for fibroblast stimulation. The result is healthier skin, better equipped to repair and defend itself.

Targeting Delicate Areas: Polynucleotides for Under-Eye Rejuvenation

The skin around the eyes is thin and one of the first areas to show ageing and fatigue. Polynucleotides offer a targeted solution for this zone, improving skin health rather than filling a void. This makes them a preferred treatment for under eye rejuvenation.

Addressing Dark Circles, Fine Lines, and Crepey Under-Eye Skin

Dark circles are often caused by thin skin revealing underlying vasculature and pigmentation. Polynucleotides thicken the dermal layer, making skin less transparent and improving its structural integrity. By boosting microcirculation and cellular turnover, they can also reduce the pigmented component of dark circles. This regenerative effect simultaneously smooths fine lines and improves the crepey texture that traditional fillers can exaggerate, as detailed in our comparison of polynucleotides to traditional tear trough fillers.

Why Polynucleotides are a Safer Choice for the Periorbital Area

The tear trough area is anatomically complex, and treatment requires precision. HA fillers, while effective for volume loss, carry a risk of the Tyndall effect—a bluish discolouration if placed too superficially in thin skin. Polynucleotides do not present this risk as they are not a gel-like implant. Their liquid consistency and regenerative properties make them a safer alternative for thin under-eye skin, promoting tissue improvement without puffiness or discolouration.

Rejuvenating the Face and Neck: Addressing Laxity and Skin Quality

Beyond the eyes, polynucleotides are effective for improving skin quality on the face, neck, and décolletage. These areas are exposed to environmental stressors that accelerate collagen and elastin breakdown, leading to laxity, fine lines, and a dull complexion.

Improving Facial Firmness and Overall Radiance with Bio-Stimulation

A full-face bio-stimulation protocol with polynucleotides can improve skin elasticity and tone. By stimulating fibroblast activity across the cheeks, jawline, and perioral region, the treatment restores the skin’s support structure. Patients observe a reduction in fine lines, a more hydrated and supple texture, and a natural radiance from healthier skin. This approach restores vitality without altering facial features.

Combating Crepey Skin and Neck Lines with Regenerative Therapy

The neck and décolletage often show age with crepey texture and horizontal lines. The skin here is thinner with fewer oil glands, making it prone to dryness and laxity. Polynucleotides are an effective neck lines treatment, working to thicken and fortify this skin. The therapy smooths fine lines and improves the cross-hatched, crepey appearance for a firmer, more youthful contour. This treats crepey skin and restores a cohesive appearance between the face and neck.

Beyond Anti-Ageing: Polynucleotides for Rosacea and Skin Texture

Polynucleotides’ regenerative capabilities extend beyond age-related concerns. Their anti-inflammatory and tissue-repair properties make them a therapeutic option for managing specific dermatological conditions and improving skin texture.

The Anti-Inflammatory Benefits for Rosacea-Prone Skin

Rosacea is a chronic inflammatory condition characterized by redness, flushing, and a compromised skin barrier. Polynucleotides down-regulate inflammation and strengthen the skin’s structure. Research in journals like the *Journal of Clinical Medicine* shows Polydeoxyribonucleotide (PDRN) promotes tissue repair and reduces inflammation. This calms redness and improves the skin’s resilience against triggers, making it a supportive rosacea treatment within a comprehensive management plan.

Remodelling Acne Scars and Refining Pores

Atrophic acne scars are depressions caused by collagen loss during the inflammatory healing process. Polynucleotides stimulate new collagen production within these scarred areas, gradually raising the depressions and creating a smoother surface. This same mechanism improves skin structure and elasticity, which can tighten and reduce the appearance of enlarged pores for a more refined, even skin texture.

The Rejuva London Difference: Doctor-Led Precision for Optimal Results

Safe, natural-looking results with polynucleotides depend on practitioner expertise. At Rejuva London, every injectable treatment is performed exclusively by a medical doctor with extensive training in facial anatomy and aesthetic techniques.

Why Doctor-Led Expertise Matters for Polynucleotide Injections

An understanding of facial anatomy—including the layers of the skin, location of blood vessels, and nerve pathways—is essential for safe injections, especially in high-risk zones like the under-eye area. Our doctors, led by Dr. Kristy Lau (Imperial College London), apply this knowledge to place the product at the optimal depth for maximum cellular stimulation while minimizing risks.

Integrating Polynucleotides into Your Bespoke Treatment Plan

Polynucleotides are a component of a holistic anti-ageing strategy. During your consultation, which may include a VISIA Skin Analysis, our doctors will design a personalised plan. Polynucleotides can prepare the skin for energy-based devices like Ultherapy or Thermage FLX, enhancing their collagen-building effects. They can also be combined with other injectables for comprehensive results, as detailed in our guide to integrating polynucleotides with other aesthetic treatments.

Your Polynucleotide Journey: What to Expect and How to Begin

A regenerative treatment journey begins with a medical consultation to assess your skin concerns and aesthetic goals.

The Timeline for Visible Polynucleotide Results

Results from polynucleotide treatments are progressive, not instantaneous. While an initial improvement in hydration and skin radiance may be seen within a few weeks, the regenerative effects appear over time. Improvements in skin firmness, elasticity, and texture become apparent after 2-3 months as new collagen and elastin mature.

Frequently Asked Questions

What are the primary polynucleotide treatment areas?

At our Harley Street clinic, the primary polynucleotide treatment areas include the delicate under-eye region for dark circles, the full face for improving skin quality, and the neck and décolletage to address crepey texture. Our doctors target these specific zones to stimulate cellular repair for natural-looking rejuvenation.

Can polynucleotides be used to lift the face?

Polynucleotides are not a lifting treatment like Ultherapy or a surgical facelift. Instead of adding volume or pulling tissue, they work at a cellular level to improve skin density, elasticity, and hydration. This regenerative process results in a firmer, more radiant appearance over time in key facial areas.

How do polynucleotides differ from tear trough fillers for the under-eye area?

Traditional tear trough fillers add volume using hyaluronic acid, which can sometimes lead to puffiness or a Tyndall effect. Polynucleotides, however, are bio-stimulators that regenerate the skin from within, thickening the tissue and improving dark circles without adding artificial volume. This makes them an excellent option for thin, delicate under-eye skin.

Is it possible to treat the neck and eyes in the same session?

Yes, treating multiple areas in a single session is both safe and effective for comprehensive rejuvenation. Our doctors often combine polynucleotide applications for the eyes, face, and neck to create a harmonious and balanced result. A personalised treatment plan is developed during your initial consultation.

Are polynucleotides safe for all skin types and areas?

Yes, polynucleotides have an excellent safety profile due to their high biocompatibility with human tissue. They are suitable for all skin types and are particularly effective for sensitive zones like the under-eyes. At Rejuva London, all injections are performed exclusively by our trained medical doctors to ensure the highest standards of safety and precision.

How can I determine the best polynucleotide treatment areas for my concerns?

The best way to identify the ideal polynucleotide treatment areas for your specific needs is through a comprehensive medical consultation.
