Are polynucleotides better than PRP for skin rejuvenation?

For most clients seeking skin rejuvenation, polynucleotides offer more consistent and predictable results. They provide superior hydration, standardised collagen stimulation, and anti-inflammatory benefits. However, PRP remains an excellent option for clients who prefer autologous treatments or are specifically seeking hair restoration.

How many sessions of polynucleotide therapy do I need?

Most clients achieve optimal results with 2-3 sessions of polynucleotide therapy spaced 3-4 weeks apart. This is typically fewer sessions than PRP, which usually requires 3-4 treatments. Your practitioner at Mesglo London will recommend a personalised treatment plan during your consultation.

Is polynucleotide therapy painful?

Most clients describe the treatment as very comfortable. We apply a topical numbing cream before treatment to minimise any discomfort. The injections themselves use very fine needles, and the procedure is generally well-tolerated. Any mild discomfort typically subsides within minutes.

Can I have PRP if I take blood thinners?

Blood-thinning medications can affect PRP quality and increase bruising risk. If you take blood thinners, polynucleotide therapy may be a better alternative as it does not require a blood draw. Always disclose all medications during your consultation at Mesglo London.

How soon will I see results from polynucleotide therapy?

Many clients notice improved skin hydration and radiance within the first week. The full regenerative effects, including improved firmness and reduced fine lines, develop over 4-6 weeks as new collagen is produced. Results continue to improve for up to three months after your final session.

Polynucleotide vs PRP: Which Is Better?

Written by Rahena, Level 7 Aesthetic Practitioner | Mesglo London

When it comes to regenerative aesthetic treatments, two options consistently dominate the conversation: polynucleotide therapy and platelet-rich plasma (PRP). Both promise to rejuvenate skin and stimulate natural healing, but they work through fundamentally different mechanisms and deliver distinct results. At Mesglo London, our Marylebone clinic offers both treatments, and our practitioners have extensive experience helping clients choose the right approach for their individual needs. This in-depth comparison examines the science, results, recovery, and suitability of each treatment to help you make an informed decision.

Understanding Polynucleotide Therapy

Polynucleotide therapy uses highly purified DNA fragments, typically derived from salmon or trout DNA, to stimulate the skin's natural regenerative processes. These fragments, known as polynucleotides (PN) or polydeoxyribonucleotides (PDRN), act as biological scaffolds that attract fibroblasts — the cells responsible for producing collagen and elastin — to the treatment area.

Once injected, polynucleotides activate specific cell surface receptors (A2A adenosine receptors) that trigger a cascade of regenerative responses. This includes increased fibroblast proliferation, enhanced collagen synthesis, improved tissue hydration through water-binding properties, and anti-inflammatory effects that protect existing collagen from degradation.

The standardised nature of polynucleotide preparations means that every treatment delivers a consistent, predictable dose of bioactive molecules. This consistency is one of the key advantages over treatments that rely on the patient's own biological material.

Understanding PRP (Platelet-Rich Plasma) Therapy

PRP therapy involves drawing a small amount of the patient's own blood, processing it in a centrifuge to concentrate the platelets, and then injecting this platelet-rich solution into the treatment area. Platelets contain growth factors — including PDGF, TGF-β, VEGF, and EGF — that play essential roles in tissue repair and regeneration.

The appeal of PRP lies in its autologous nature: because the treatment uses your own blood, there is virtually no risk of allergic reaction or rejection. The concentrated growth factors stimulate collagen production, improve blood supply to the treated area, and promote cellular renewal.

However, PRP results can vary significantly between patients. Factors such as age, overall health, platelet count, and even medications can affect the quality and concentration of the PRP preparation. This variability means that outcomes are less predictable compared to standardised treatments like polynucleotides.

Head-to-Head Comparison

To help you understand the practical differences between these two treatments, we have compiled a detailed comparison across the factors that matter most to our clients at Mesglo London.

Factor	Polynucleotide Therapy	PRP Therapy
Source Material	Purified salmon/trout DNA	Patient's own blood
Preparation	Ready to use	Requires blood draw and centrifuge
Consistency	Highly standardised	Varies by patient
Mechanism	A2A receptor activation	Growth factor release
Collagen Stimulation	Strong and consistent	Moderate, variable
Hydration Effect	Excellent (water-binding)	Minimal
Anti-inflammatory	Yes, significant	Moderate
Treatment Time	30-45 minutes	45-60 minutes
Downtime	24-48 hours	24-72 hours
Sessions Needed	2-3 sessions	3-4 sessions
Results Duration	9-12 months	6-9 months
Price Range (London)	From £300	From £350
Blood Draw Required	No	Yes
Allergy Risk	Very low	None (autologous)

At Mesglo London, we find that approximately 70% of our clients choose polynucleotide therapy for its consistency and superior hydration benefits. However, the best treatment is always the one tailored to your individual needs.

Which Treatment Is Right for You?

The choice between polynucleotide therapy and PRP depends on your specific concerns, preferences, and goals. At Mesglo London, we take a personalised approach, assessing each client's skin condition, medical history, and desired outcomes before recommending a treatment plan.

Polynucleotide therapy tends to be the better choice for clients seeking consistent, predictable results with minimal preparation time. It is particularly effective for deep hydration, skin laxity, and overall skin quality improvement. The treatment is also ideal for clients who prefer not to have blood drawn.

PRP may be preferred by clients who want a completely autologous treatment using only their own biological material. It can be particularly effective for hair restoration and for clients with specific wound healing needs. However, the variability in results means that outcomes are less predictable.

Can You Combine Polynucleotides and PRP?

Yes, and at Mesglo London we increasingly recommend combination protocols for clients seeking the most comprehensive results. Combining polynucleotide therapy with PRP creates a synergistic effect: the polynucleotides provide a consistent, standardised regenerative stimulus while the PRP adds a personalised boost of autologous growth factors.

This combination approach is particularly effective for clients with advanced signs of ageing, significant sun damage, or those seeking both facial rejuvenation and hair restoration. The treatments can be performed in the same session or alternated across a treatment course, depending on your practitioner's recommendation.

Our Marylebone clinic has developed specific combination protocols that optimise the timing and delivery of both treatments to maximise results while minimising downtime.

Conclusion

Both polynucleotide therapy and PRP offer genuine regenerative benefits, but they are not interchangeable treatments. Understanding the differences in mechanism, consistency, and suitability is essential for making the right choice. At Mesglo London, our expertise in both modalities allows us to recommend — and often combine — these treatments for optimal results. Whether you choose polynucleotides, PRP, or a combination of both, our Marylebone clinic provides the clinical excellence and personalised care you deserve.
