Dr Rami Haidar explains what patients can realistically expect at each stage of a polynucleotide treatment course, how long results last and what determines when a maintenance session is needed.
Most patients who research polynucleotides find a thorough explanation of what the treatment is and how it works. What they are less likely to find is a clear answer to the practical questions that come after that decision has been made: how quickly will I see a difference, how long will it last, how many sessions do I actually need, and when do I come back?
This article addresses those questions directly, with the clinical context that makes the answers useful rather than generic.
Polynucleotides are purified DNA fragments, typically derived from salmon, that are injected into the skin to support cellular regeneration at the tissue level. They work by stimulating fibroblast activity, which drives collagen and elastin production, and by creating an environment that supports the skin’s natural repair processes. Unlike hyaluronic acid-based treatments, which provide immediate volume or hydration, polynucleotides work by improving the biology of the skin itself over time.
This biological mechanism is what determines the results timeline. The improvement is not instantaneous because it depends on the body’s own cellular response, which takes weeks to months to fully develop.
The first improvements most patients notice are in skin hydration and texture. Within two to four weeks of the first session, the skin typically feels more comfortable, plumper and less reactive. Surface dryness and the tightness that some patients experience from dehydrated skin often improve within this window.
These early changes reflect the direct hydration-supporting effects of the polynucleotide molecules themselves, as well as early fibroblast activation. They are a sign that the treatment is working, but they do not represent the full result.
The more significant changes, those related to collagen remodelling and genuine improvements in skin quality, develop over the four to twelve week period following each session. During this phase, new collagen produced by activated fibroblasts begins to mature and integrate into the dermal matrix.
What patients notice at this stage includes improved skin firmness and resilience, a reduction in the visibility of fine lines particularly in delicate areas such as the under-eye and perioral region, more even skin tone and a healthier overall appearance. The skin is not simply hydrated at this stage — it is structurally better.
This is also the window during which most patients see the most clinically meaningful change, and it is the reason a single session does not capture the full potential of the treatment.
A standard polynucleotide treatment course involves two to three sessions spaced three to four weeks apart. Each session builds on the previous one, with the collagen-stimulating response layering progressively. The cumulative result of a full course is significantly greater than a single session.
After completing a course, most patients notice a meaningful and sustained improvement in skin quality across several parameters: hydration, firmness, texture, fine line reduction and brightness. In the under-eye area, where the skin is thinnest and most responsive, the improvement in translucency and the reduction in fine lines can be particularly noticeable.
The full benefit of the course is typically apparent at around eight to twelve weeks after the final session, as the collagen produced continues to mature.
In most patients, the results from a full treatment course last between six and twelve months. The range is wide because several individual factors affect how long the improvement is maintained.
Skin condition at the start of treatment matters: patients with significantly depleted or sun-damaged skin may see faster regression because the baseline rate of collagen breakdown is higher. Age affects the speed of collagen turnover. Treatment frequency affects how well the fibroblast response is sustained over time.
In Dubai specifically, the sustained UV exposure and the dehydrating effect of the climate accelerate collagen breakdown at a faster rate than in lower-UV environments. This means that maintenance intervals in Dubai are often shorter than the European protocols from which much of the published data on polynucleotides originates.
The two most widely used polynucleotide formulations are PDRN (polydeoxyribonucleotide) and PRONOVA (highly purified polynucleotide). Both stimulate fibroblast activity and support tissue regeneration, but they differ in the length and purity of the DNA fragments used and in their concentration in the injectable product.
PRONOVA products tend to use longer, more intact polynucleotide chains at higher concentrations, which some clinical evidence suggests may produce a stronger or more durable fibroblast response in certain presentations. PDRN products are well established with a long clinical history and remain highly effective across a broad range of skin concerns.
The clinical significance of this distinction for any individual patient depends on their skin condition, the area being treated and the specific concern. A practitioner should be able to explain which formulation they use and why, based on the patient’s presentation rather than on product preference.
Rather than waiting until the results have fully faded, most patients benefit from a maintenance session before that point. Booking at six to nine months after a completed course, or when early signs of regression become noticeable, sustains the cumulative improvement rather than starting from a lower baseline each time.
In Dubai, where the climate continuously challenges skin hydration and collagen integrity, a maintenance interval of six months is often appropriate for patients who want to keep the result at its best. Patients with particularly depleted or UV-damaged skin may benefit from a session every four to five months during the first year.
These intervals are established at consultation and can be adjusted based on how each individual’s skin responds.
Treatment planning at the clinic in Jumeirah, Dubai is built around the individual patient’s skin biology and goals rather than a standard protocol applied uniformly. The specific formulation, the number of sessions, the interval between them and the maintenance schedule are all determined by a clinical assessment of the skin and discussion of the patient’s priorities.
A consultation is the appropriate starting point for anyone planning a polynucleotide treatment course or considering maintenance after previous treatment.
The first noticeable improvements in skin hydration and surface texture typically appear within two to four weeks of the first session. More significant changes related to collagen remodelling develop over the four to twelve weeks following each treatment.
In most patients, the results from a full treatment course last between six and twelve months. Dubai’s high UV environment and climate dehydration can accelerate collagen breakdown, making maintenance intervals shorter than in lower-UV climates for some patients.
A single session provides the early benefits of fibroblast activation but does not capture the full potential of the treatment. A course of two to three sessions is standard and produces a significantly greater and more lasting result than a single session.
Both are polynucleotide formulations that stimulate fibroblast activity and support skin regeneration. PRONOVA uses longer, more purified polynucleotide chains at higher concentrations. PDRN has a long clinical history and is effective across a broad range of presentations. The choice between them depends on the individual’s skin condition and the specific concern being treated.
Most patients benefit from a maintenance session at six to nine months after completing a course, or when early signs of regression become noticeable. In Dubai’s climate, a six-month interval is often appropriate. The specific schedule is determined based on individual skin response.
Yes. Polynucleotides are frequently combined with HA-based skin boosters, anti-wrinkle injections or filler as part of a broader skin quality or facial treatment plan. The combination and sequence of treatments depend on the individual’s goals and are discussed at consultation.
