If you have been researching polynucleotide treatments, you have probably seen them described as “regenerative“, “repairing” or “collagen-stimulating“. All of that can sound impressive, but it does not always answer the basic question people actually want answered: what do polynucleotides really do to the skin, and what kind of result should you expect?
The simplest answer is this: polynucleotides are used to improve skin quality rather than add volume. They are chosen to support hydration, elasticity, texture and skin repair, with results developing gradually over a course of treatment rather than appearing instantly in the way filler sometimes can.
Updated: April 2026 — Doctor-led guide from Dr Suresh Mohan (GMC-registered), Wimbledon.
A practical guide to what polynucleotides do to the skin, including hydration, texture, elasticity, realistic results, and what the treatment does — and does not — do.
For the right patient, that can make them a very attractive option. They are especially appealing to people who want their skin to look healthier, fresher and better supported, but who do not want to look artificially “filled” or obviously altered.
In simple terms
Polynucleotides help improve the quality of the skin itself — including hydration, texture and resilience — rather than replacing lost volume or changing facial shape.
Polynucleotides are used to improve skin quality, hydration and resilience rather than to add volume.
How do polynucleotides work?
Polynucleotides are injectable fragments used in regenerative aesthetic treatments to support the skin’s own repair environment. They are associated with hydration, tissue support and improvements in elasticity, texture and fine lines. In practical terms, that means the treatment is aimed at helping the skin behave more like healthier, better-supported skin.
This is one reason they have become so popular in natural-looking aesthetic medicine. They are not chosen because they give an instant “done” look. Instead, they appeal to patients who want a more subtle shift: skin that feels a little stronger, looks less tired, and gradually appears smoother and better hydrated.
That also explains why polynucleotides are often discussed differently from filler. Filler is primarily about structure and volume. Polynucleotides are more about skin quality and tissue support. That distinction matters, because many patients think they need volume when what they really want is better skin.
What improvements can you realistically expect?
This is where it helps to be specific.
Polynucleotides are usually used to improve:
- skin hydration
- texture & elasticity
- dark circles around the eyes & skin pigment
- acne scarring
- crepey or fragile-looking skin
- fine lines
- overall skin quality and resilience
Patients often describe the result less as a dramatic transformation and more as a general improvement in how the skin looks and feels. The skin may appear fresher, smoother, slightly firmer and better supported. That can be particularly valuable in delicate areas, where the goal is not to create volume, but to improve the condition of the skin itself.
Polynucleotides are usually at their best when the problem is skin quality and appearance. They are not the answer to every aesthetic concern, but they can be very helpful when the skin has become thinner, more fragile, more dehydrated or simply less vibrant with age.
If you would like to see how this can look in practice, you can also read more about polynucleotides before and after.
In delicate areas such as under the eyes, improving skin quality can be more important than adding volume.
What polynucleotides do not do
Polynucleotides do not behave like dermal filler. They are not designed to replace significant volume loss, lift heavy tissue, or create a more sculpted contour. If someone has a true tear trough hollow, marked facial volume loss, or a deeper structural issue, another treatment may be more appropriate.
They are also not a miracle treatment for every type of dark circle, puffiness or under-eye bag. Under-eye concerns can come from hollowing, pigmentation, thin skin, swelling, shadowing, or a mixture of these. A treatment that improves skin quality can be extremely helpful in some cases, but it will not fix every cause.
That is why a good consultation matters. The right injectable depends on what is actually causing the concern, not just on what is popular online.
Important:
Polynucleotides are best thought of as a skin-quality treatment, not a volumising treatment.
Common Questions About Polynucleotides
Polynucleotides are often described as regenerative or skin-rejuvenating treatments, but many patients still have very practical questions about what they can really do, how quickly they work, and whether they are right for concerns such as under-eye ageing or tired-looking skin. Here are some of the questions people ask most often.
Do polynucleotides make you look younger?
They can certainly help the skin look more refreshed and healthier, and that often translates into a more youthful appearance. But the effect is usually subtle and cumulative, not dramatic and immediate.
This is one of the treatment’s strengths. Patients who choose polynucleotides are often not trying to look like a different person. They want the skin to look less tired, more hydrated, more resilient and a little smoother. In other words, they are usually aiming for quiet rejuvenation rather than visible cosmetic change.
That is why polynucleotides can suit patients who like the idea of aesthetic medicine but are wary of looking overtreated. The result, when well chosen, tends to be one of improvement rather than obvious intervention.
How long do results take?
Polynucleotides are usually not treated as a one-off appointment. Most patients need a course of treatment, because the result is designed to build over time rather than appear all at once.
Some patients notice early changes in hydration or skin quality after the first session, but the more meaningful improvement usually becomes clearer as the course progresses. This is part of the appeal for many people: the skin improves gradually, in a way that tends to look natural.
Are polynucleotides good for under-eye skin?
Yes — and this is one of the reasons interest in polynucleotides has grown so much.
The under-eye area is delicate. The skin is thin, it shows fatigue quickly, and it can start to look crepey, dull or fragile with age. This is exactly the kind of area where a treatment focused on skin quality rather than bulk can make sense.
If the main issue is crepey skin or poor-quality under-eye skin, polynucleotides can be a very good option. They are often chosen to support hydration, improve texture and help the area look fresher and less tired. However, if the main concern is a true hollow beneath the eye, the discussion may be different.

In delicate areas such as under the eyes, improving skin quality can be more important than adding volume.
Is one session enough?
Usually, no — at least not if you are hoping for the kind of result most people mean when they ask whether polynucleotides “work”.
One session may still give a subtle boost, but a course is normally recommended because repeated sessions are more likely to produce noticeable improvement in hydration, texture and resilience. That is why patients are usually advised to think of polynucleotides as a treatment plan rather than a one-off quick fix.
Are polynucleotides safe?
Polynucleotides are generally considered to be well tolerated when used appropriately, with side effects usually being mild and short-lived. As with many injectable treatments, the most common short-term effects are redness, swelling, tenderness or bruising around the injection points. If you are planning treatment, you may also find my complete guide to polynucleotides aftercare helpful.
However, “well tolerated” does not mean risk-free, and no injectable should be presented that way. Treatment choice, product choice, technique, aftercare and patient selection all matter. This is why it is important to seek treatment from a properly qualified medical professional who can assess whether the treatment is suitable for you in the first place.
Who tends to be a good candidate?
Polynucleotides may be a good option for patients who:
- want gradual, natural-looking improvement
- are more concerned about skin quality than volume
- have dull, dehydrated, thin or crepey skin
- want support in delicate areas such as the under-eyes, neck or hands
- prefer subtle rejuvenation over a dramatic “before and after” change
They may be less suitable when the main concern is:
- marked volume loss
- heavier tissue descent
- stronger structural hollowing
- under-eye bags or swelling caused by another issue
- expectations of an instant filler-like result
What about the “salmon sperm” question?
This comes up a lot online, so it is worth addressing clearly and calmly.
Polynucleotides used in aesthetic medicine are commonly described as purified DNA fragments, often sourced from fish such as salmon or trout. In popular media, this has led to the phrase “salmon sperm facial”, but that phrase is more sensational than helpful. What matters is that the material is processed, purified and formulated for medical aesthetic use.

Polynucleotides in Wimbledon
If you are considering polynucleotides in Wimbledon, the most important thing is not simply choosing a treatment because it is popular or widely discussed online.
It is understanding:
- what is bothering you most
- whether the issue is mainly skin quality, volume loss or both
- what kind of result is realistic
- and whether polynucleotides are the right treatment for that concern
Doctor-led treatment and careful assessment are central to safe, natural-looking aesthetic results.
At my clinic, I take a conservative, doctor-led approach because the best aesthetic results usually come from careful assessment, appropriate treatment choice and realistic expectations, not from overpromising. The NHS advice before having a cosmetic procedure explains why it is important to choose a qualified practitioner, understand the procedure properly, and know what aftercare and risks to expect before proceeding.
