Polynucleotides in Rossendale

Regenerative injectable treatment that works on skin quality — hydration, elasticity and firmness — rather than adding volume.

In short

Polynucleotides are purified DNA fragments injected into the skin to improve its quality rather than add volume, given as a course of three sessions two to four weeks apart, with results building over eight to twelve weeks.

How long it lasts
6 to 12 months, then maintenance
When you see it
hydration in 2 weeks, firmness and texture over 8 to 12 weeks
Downtime
small raised bumps for a few hours; bruising possible under the eyes
Does it hurt
mild — a fine needle, and the under-eye is the most sensitive area
Sessions
a course of 3, two to four weeks apart

Polynucleotides are chains of purified nucleotides — the building blocks of DNA — used to support the skin's own repair processes. They are not a filler. Nothing is being added to change your shape; the treatment works at tissue level to improve how the skin behaves, which is why it suits thin, crepey or tired-looking skin better than a volumising product would.

What it does

Polynucleotides support fibroblast activity — the cells responsible for producing collagen and elastin. The effect is on skin quality: hydration, elasticity, firmness and overall texture. It is a gradual change rather than an immediate one, and it builds across a course.

Because the treatment improves the tissue rather than filling it, it is often the right first step for someone who has been told they need filler but whose real concern is skin thinning — particularly around the eyes, where volume is rarely the answer.

Three panels show a symbolic nucleotide chain, a skin layer and a research document. They distinguish the material from its intended use and the evidence needed to assess it.

A closer look

Material, purpose, evidence

  1. The material

    Polynucleotides are chains of nucleotides, commonly obtained from purified fish-derived DNA.

  2. The aim

    They are used for skin quality concerns, rather than as a substitute for a structural filler.

  3. The evidence

    Research is developing. Products, protocols and study quality vary, so results should not be promised.

The chain is symbolic, not a molecular model. Product suitability, including allergies, must be checked against the specific product information.

The under-eye area

The under-eye is where polynucleotides most often outperform the alternatives. Skin here is thin, mobile and unforgiving, and filler placed into a hollow that is really a texture problem tends to look worse over time, not better.

Assessment matters more than the product. Part of the consultation is working out whether what you are seeing is volume loss, skin quality, pigmentation, or the shadow cast by the orbital rim — because those four things have four different answers.

Course and results

A course is typically three sessions spaced two to four weeks apart, with results continuing to develop for some weeks after the final session. Maintenance is usually every six to twelve months depending on the area and how your skin responds.

You will be given written aftercare before you leave, and a direct number to reach me on if anything concerns you afterwards. Reviews are offered at two weeks so we can assess the result together and adjust if needed.

What the whole course involves, start to finish

This is a course rather than an appointment, and the gaps between sessions are part of how it works.
StageWhat happensWhen
AssessmentYour skin is assessed for what it actually lacks — hydration, density, or repair capacity. These need different productsBefore the first session
Session 1A series of small injections at fixed points, around 20 minutesDay 0
Straight afterwardsSmall raised bumps at each point, settling within hours to a day. Little else to see0–24 hours
The gapNothing visible. This is the phase people mistake for the treatment not working2–4 weeks
The rest of the courseSessions 2 and 3, sometimes 4, at the interval that product calls forWeeks 2–12
The resultFirmness, hydration and texture — judged here, not before8–12 weeks after the final session
MaintenanceA single top-up session rather than a repeat course6–9 months

How the plan is decided

What your skin is short of decides the product

The question at assessment is not which brand you have heard of. It is whether your skin is dehydrated, whether it has genuinely thinned and lost density, or whether its repair machinery needs supporting — because those three want different things, and a product chosen for the first will underperform on the third.

Skin that is reasonably thick but dull and flat generally does well with hydration and firmness. Skin that is crepey and fragile, showing fine lines at rest, usually needs building blocks or a repair signal instead.

Why a course, and why the spacing is not padding

One session produces a signal; a course produces a sustained one, and sustained signalling is what actually changes tissue. The intervals are set by how long the previous session keeps working — treating again before that has finished spends a session on skin that was already busy.

What this category cannot do

None of it changes the shape of your face. If what bothers you is lost volume, a flat midface or a heavy jowl, the honest answer is that you are looking at the wrong category — and a clinic offering a skin treatment for a structural problem is selling rather than assessing.

Often suits

  • Thin, crepey or dehydrated skin
  • Fine lines from skin thinning rather than volume loss
  • Under-eye texture and crepiness
  • Anyone who wants improvement without a change in shape

Not suitable if

  • Anyone pregnant or breastfeeding
  • Active infection or inflammatory skin condition at the treatment site
  • Anyone under 18

Common questions

Polynucleotides — what people ask

Are polynucleotides the same as a filler?
No. Dermal fillers add volume and structure. Polynucleotides do not add volume — they support the skin's own repair processes to improve quality, elasticity and hydration. They are often used together, but they do different jobs.
How many sessions will I need?
Usually three, spaced two to four weeks apart. Some areas and some skin types benefit from more. I will give you a realistic plan at consultation rather than committing you to a course before I have assessed you.
Is there downtime?
Small raised bumps at the injection points are normal and usually settle within a few hours to a day. Bruising is possible, particularly under the eyes. Most people return to normal activity the same day.
When will I see a difference?
Skin quality changes are gradual. Most people notice hydration and glow within a couple of weeks, with firmness and texture continuing to improve over the course and for several weeks after it finishes.
Are polynucleotides safe?
The risks are mostly the ordinary ones of any injection — bruising, swelling, small bumps at the injection points, and rarely infection. The products are highly purified and the reaction rate is low. Under the eyes is the area with the most bruising and the least margin for error, which is a reason to ask how often your practitioner treats it.
Can I have polynucleotides while pregnant or breastfeeding?
No. Injectable treatment is not offered during pregnancy or breastfeeding, on the same precautionary basis as everything else injectable here.
