Polynucleotides are chosen for regeneration, not for volume
This is the direction for skin that is thin, reactive, has weaker elasticity or is burdened by environmental stress. The doctor assesses the area, tissue quality, tendency for swelling and the goal. Especially under the eyes, this last point is crucial: pigment shadow, vascular shadow, anatomical depression and swelling may look similar in a photo, but they do not respond to the same stimulus.
If the main problem is a deep tear trough or significant volume loss, polynucleotides may improve the quality of the skin over the problem, but they will not change its structure. This is an important distinction, as subtle texture improvement can be valuable, but it should not be sold as an anatomical correction.
Profhilo works more broadly on skin quality and hydration
Profhilo is not a classic contouring filler. The doctor selects it when the goal is a diffuse improvement in quality, elasticity and hydration, rather than a point-based replenishment of a furrow. The area, skin condition and preparation variant matter. A person expecting a change in facial features may find the result too subtle; a person fearing volume may be looking for exactly that subtlety.
A structural variant is not automatically a "stronger version". It is a different tool for a different problem. The choice should result from an examination of the face, not from the belief that a more expensive or newer name solves more.
Mesotherapy makes sense when a selected plan of ingredients is needed
Mesotherapy is a broad category, not a single preparation. Its profile depends on the composition, indication, technique and area. It can support hydration and skin condition, but the "cocktail" label alone decides nothing. Ask about the product name, product status, composition and the reason for the choice. A list of many ingredients does not have to be better than a simpler formula selected for specific skin.
- Thin, lax skin and a regenerative goal steer the conversation towards polynucleotides.
- Diffuse dehydration and loss of elasticity may steer you towards Profhilo.
- The need for a specific protocol of ingredients may speak in favour of mesotherapy.
- Significant volume loss requires a separate conversation about anatomy and other tools.
- Swelling, active skin disease or an unclear lesion are reasons for diagnostics, not for a quick choice of injection.
Three treatments — three completely different mechanisms
We classify all three as a group of so-called biostimulators or revitalising treatments — and this is where the confusion begins. Their common denominator is rebuilding the skin "from within". But the mechanism, depth of action and clinical goal differ significantly. In short: mesotherapy delivers ingredients, Profhilo intensely hydrates and lifts through hyaluronic acid, polynucleotides repair and regenerate skin cell DNA. Each of them works at a different biological level — and that is why they complement each other so well.
Mesotherapy
delivers a nourishing cocktail
- vitamins, amino acids, peptides, hyaluronic acid — depending on the formula
- nourishes, hydrates and stimulates the skin to work
- wide range of indications: face, neck, décolletage, scalp
- results are visible gradually, they require a programme
Profhilo
intense lifting and hydration
- exceptionally concentrated hyaluronic acid — high and low molecular weight
- spreads under the skin, stimulates collagen and elastin
- "bio-remodelling" effect — tension, radiance, density
- classically 2 sessions one month apart, the result lasts several months
Polynucleotides
deep cellular regeneration
- DNA fragments obtained from salmon or a synthetic plant-based version
- stimulate fibroblasts to synthesise collagen and elastin
- repair damage at a cellular level — clear improvement in skin quality
- particularly effective for laxity, scars, hyperpigmentation, skin after sun exposure
Polynucleotides, in turn, belong to the same category as Profhilo (biostimulators), but they work completely differently: while Profhilo focuses on intense hydration and the lifting effect of hyaluronic acid, polynucleotides aim for regeneration at a genetic level — they give fibroblasts "repair instructions" to rebuild the skin from the ground up. The result is more durable, but it requires time and patience.
How to recognise which concerns you more — the mirror test
Three questions that allow you to narrow the field — not as a diagnosis, but as a starting point for a conversation with a doctor:
- Your skin looks "dry and dull", expressionless, you lose radiance even after applying moisturiser → the skin is calling for intense revitalisation → direction: mesotherapy or Profhilo.
- You feel that your skin is thinner, lax, has lost its "elasticity" over the years — you pull your cheek and it returns slowly → damaged collagen and elastin → direction: Profhilo or polynucleotides.
- You have a history of excessive sun exposure, acne scars, hyperpigmentation, skin "tired from chronic stress" → damage at a cellular level → direction: polynucleotides.
- You want to maintain results or "tune" your skin preventively, you are 30+ and take care of yourself on an ongoing basis → hydration and nourishment → direction: mesotherapy as a basic programme.
It is worth remembering that a "home test" is only a simplified filter. In practice, skin rarely has one problem — more often it is dry, lax and has a history of sun exposure. Therefore, after a consultation, the doctor may propose a combination rather than choosing one treatment.
When to combine — and why it is often the best answer
One of the biggest misunderstandings in aesthetic medicine is that treatments are "mutually exclusive" — as if choosing one closes the door to the others. In reality, it is almost never about one or the other — it is about the right sequence and logic of combining. Here are the combinations that appear most often in a well-planned therapy:
Mesotherapy + Profhilo
mesotherapy nourishes and prepares the skin, Profhilo adds an intense hydration and lifting effect. Often in a sequence: a mesotherapy programme, then Profhilo as a "seasonal finish".
Polynucleotides + mesotherapy
Cellular regeneration plus nourishment — a long-term plan for skin with deficits. Polynucleotides repair, mesotherapy nourishes.
Profhilo + polynucleotides
A combination for those with visible sagging and compromised skin quality. Profhilo provides a faster result, while polynucleotides offer a longer-lasting one.
All three in a yearly programme
For mature skin or skin with a complex history (sun, stress, deficiencies) — spread over time, with a consultation at each stage.
One more note: none of these treatments is a one-off. Results last for varying periods — from a few months to a year or longer — depending on your individual skin, lifestyle and the regularity of the treatment. A good clinic does not sell a "one-off miracle", but a plan with stages and expectations for each one.
Who is each of these treatments particularly suitable for
If you feel you still do not know "which one is for you" — that is normal. Aesthetic dermatology does not work like a single-dish menu. However, a few profiles that recur in clinics may help you understand:
- Mesotherapy — for those who want to regularly care for their skin condition, prevent ageing, and improve hydration and radiance. Treatment often starts here before more advanced procedures begin.
- Profhilo — for those who want a visible effect of tightening and hydration in a short time. A good choice for skin that is starting to "lose elasticity" and needs a clear signal for regeneration.
- Polynucleotides — for those with real skin damage: excessive sun, scars, premature ageing, and thin skin lacking elasticity. The result is slower, but deeper and longer-lasting.
It is also worth knowing that polynucleotides are increasingly used preventively in younger people (25–35 years old) — not because they have a problem, but because they want to prevent degradation before it appears. This is a shift in thinking from "repairing" to "investing". And it is hard to be surprised by that.

What really happens under the skin — four things at once
This is the essence of the difference between a polynucleotide and a regular hydrating preparation. A hydrating cosmetic delivers something ready-made to the skin — usually water and substances that bind it. A polynucleotide does something else: it triggers processes that the skin performs itself. It is not a delivery, it is a stimulation. It stimulates on several fronts simultaneously — and this multi-directional approach is what distinguishes it from tools that work in "one dimension".
- It wakes up fibroblasts — the collagen factories. Fibroblasts are cells that produce collagen and elastin, the scaffolding responsible for the skin's tension and elasticity. With age, they work slower and more lazily. Polynucleotides act as a "get to work" signal — they remind them how to produce the building blocks the skin has started to lack. This is why the result is structural, not superficial.
- They bind water — but from the inside. Yes, polynucleotides intensely hydrate. However, they do not do this by "greasing" the surface, but by binding water deep within the skin, where a cream cannot reach. This is structural hydration — more often felt as "skin that is finally full and rested" than as temporary comfort after applying an emulsion.
- They extinguish inflammation and oxidative stress. Polynucleotides act as antioxidants and anti-inflammatories — they protect cells from "rusting", i.e. damage driven by the sun, pollution and lifestyle. It is this soothing component that makes them well-tolerated by vascular, irritated and reactive skin.
- They improve microcirculation. Better-perfused skin is better nourished and oxygenated — and therefore skin that regenerates faster on its own. This is a quiet but important element of the whole puzzle: it creates better conditions for the rest of the processes to work at all.
The sum of these four mechanisms is skin that is denser, better tightened, more intensely hydrated and more radiant — yet none of these changes involves adding volume or changing your features. This is not a "new face". It is a better version of the same skin, brought to a state where it can work more efficiently.
Polynucleotides, hyaluronic acid and mesotherapy — why they are not the same
Polynucleotides are most often confused with three other things: a filler, a bioremodeller based on hyaluronic acid (like Profhilo), and classic mesotherapy. They all "do something to the skin", so it is easy to put them in one bag. But the difference is not a nuance — these are different categories of tools for different tasks, and that is why they often play on the same team, not against each other.
Polynucleotides (PDRN)
teach the skin to repair itself
- stimulate fibroblasts to produce collagen
- regenerate, hydrate and act as antioxidants
- thin, grey, tired, reactive skin
Hyaluronic acid / bioremodelling
hydrates and improves elasticity in a different way
- e.g. Profhilo — hybrid hyaluronic acid
- spreads in the skin, improves its "condition"
- is sometimes used alternately with PDRN
Needle mesotherapy
nourishes the skin with a cocktail
- vitamins, amino acids, peptides "deep into" the skin
- lighter, "strengthening" support
- a good entry point into the topic of skin quality
The simplest way to remember this: a filler adds volume, hyaluronic acid hydrates and remodels, mesotherapy nourishes, and a polynucleotide teaches the skin to work in its own way. That is why it makes no sense to ask "which is best" — the sensible question is: "what is failing in my case". Grey, thin and tired skin is the territory of polynucleotides. A lack of volume or a sagging oval is a completely different story and requires different tools.
Why one injection is not enough — the logic of a series
Here our instruction metaphor returns — and finally comes full circle. Since a polynucleotide does not provide the skin with a ready-made result, but assigns it work to do, it is logical that this work needs time. Fibroblasts do not produce collagen "on command" in five minutes. The skin remodels slowly, at its own rhythm — and each subsequent session reminds it of the task before it can forget.
That is why polynucleotides are a classic cumulative treatment. Hydration and a "fresher" look can be felt almost immediately — and these are the things that most often lead you astray, because they give the illusion that "this is it". Meanwhile, the actual regenerative effect is only just building up. A series of treatments spread over time provides the full effect, not a single visit — and this is one of those cases where evaluating the result after the first time is simply misleading.
- 01
immediately
noticeable hydration and a "fresher" look; small bumps at the injection sites fade within hours
- 02
the first few days
any redness or slight bruising fades — the skin begins to work "in the background"
- 04
a few weeks
the first visible results of regeneration: radiance, tension, less tired complexion
- 04
after the full series
a growing effect, usually lasting from half a year to a year — with recommended maintenance
Importantly, after the series is finished, your skin does not "deteriorate" rapidly. It simply returns to its natural ageing pace. You maintain the achieved level with single sessions every few to several months. This is not skin addiction to the treatment, but rather maintaining a state that has already been achieved.
What this means in practice — and what not to expect from polynucleotides
First, let's be honest about what this treatment will not do — as this saves you from disappointment. Polynucleotides will not fill deep furrows, add volume to sunken cheeks or lift a sagging oval. That is not their role. If your problem is facial geometry — lost support or sagging tissue — the tools are fillers, volumetry or threads. Polynucleotides work on skin quality, not its shape.
Now, who are they really for? This treatment is for skin that is tired, grey and "lifeless"; thin, "papery" skin losing tension; or dehydrated skin that does not regain comfort despite good skincare. It is also for reactive and vascular skin that needs soothing. It works perfectly in the delicate eye area, where the skin is at its thinnest. It also supports regeneration after treatments that "damage" the barrier, such as lasers or peels. Finally, it is a conscious preventative measure — used before the skin has a chance to become heavily "worn out".
Here, it is worth clearing up another misunderstanding — that this is a "feminine treatment". The regeneration mechanism is gender-neutral. The difference lies mainly in the starting point. For women, polynucleotides usually fit into a "skin quality" plan: radiance, tension, work in the thin eye area and a fresher complexion without a "done face" effect. For men, the goal is often more restorative — skin burdened by the sun, oxidative stress, daily shaving and usually a lack of routine sun protection. Both are looking for the same thing: healthier, denser, less tired skin without a visible "change". Hence the growing group of people for whom this is simply a neutral tool for skin condition.
Finally, the most important thing that no article can decide for you: whether this is the right treatment for you. "Tired skin" in one person means dehydration, in another it means loss of density, and in yet another it is actually a volume problem that a polynucleotide will not address. Whether it makes sense, and in which variant, is decided by examining your specific skin during a consultation — not by an article or an advertisement. Below, we have collected treatments that revolve around the same goal: better skin quality and regeneration.
