Polynucleotides Under Eyes in Marylebone
Polynucleotides Marylebone connects you with registered practitioners at UNTIL Marylebone who use polynucleotides under the eyes, where the skin is about half a millimetre thick, thinner than anywhere else on the body, which is why it ages first and why it responds to a treatment that repairs skin.

The short answer
What do polynucleotides do under the eyes?
Most people arrive at this treatment having decided the problem is a shadow. They have looked in a mirror in bad light, seen darkness, and gone looking for something to fill it. Sometimes that is right. Often it is not, and the difference decides whether a course of polynucleotides is money well spent or a disappointment you pay three times for.
Under-eye skin has almost no fat beneath it and very little collagen holding it. As that collagen thins, two things happen at once: the surface develops the fine crepey texture that catches the light, and the vessels underneath start showing through as a blue-grey cast. Polynucleotides work on both, because both come from the skin itself having got thinner. What they will not do is refill a hollow that has lost its fat pad, and an honest assessment will say so.

What causes dark circles and tired-looking eyes?
Three different problems produce a tired under-eye, and only one of them responds to this treatment. Plenty of people have two of the three, which is a reason to have them separated at assessment and treated in a sensible order.
Lost volume
The fat pad under the eye shrinks and descends with age, leaving a genuine trough that light falls into. Nothing that improves skin quality lifts this, because the deficit is structural.
Pigment
Some people, particularly with deeper skin tones, carry hereditary melanin in the under-eye skin that barely changes with sleep. Polynucleotides will not lighten it, and neither will filler.
Thin, poor-quality skin
Skin that has lost collagen is finely lined, holds the crease when you smile, and lets the vessels beneath show through as a purple or blue-grey cast. This is the version polynucleotides are for.
How polynucleotides work under the eyes
Placed into the dermis, polynucleotides bind water, which hydrates a layer that is chronically short of it. More importantly, they prompt the fibroblasts already living in the skin to lay down new collagen and elastin. You are not given a substance that occupies space; you are given a signal, and the tissue does the building. In an area where the whole problem is that the tissue stopped building, that is the right intervention.
It also explains the timing. The skin needs the gap between sessions to respond, which is why three appointments two to three weeks apart is the usual shape, and why the honest answer to when you will see it is the second session at the earliest and eight weeks for the real answer. How polynucleotide injections work covers the mechanism in full.
Under-eye wrinkles and fine lines
Two kinds of line appear under the eyes. The first sits in the skin at rest: fine, crepey creasing in skin about half a millimetre thick that has lost collagen, which is the kind polynucleotides soften, because thickening that skin is what they do. The second appears only when you smile or squint, made by the ring of muscle around the eye folding the skin above it. Polynucleotides do not change how that muscle moves, so they improve the texture the smile folds rather than the fold itself.
Most people have some of both. Expect the lines at rest to look finer and to hold concealer better from around the second session, with the result judged about eight weeks after the first. Daily sunscreen and sunglasses slow the thinning that causes them in the first place.
Polynucleotides or tear trough filler?
They are often discussed as alternatives and they are not. Tear trough filler is hyaluronic acid placed deep, usually onto bone, to replace volume that has gone. It works immediately, it is reversible, and in the right hands on the right patient it is very effective. It does nothing for the quality of the skin lying over it. Polynucleotides are placed superficially across the area to change the skin, and they do nothing for volume.
If your under-eye is hollow and the skin is good, filler is your treatment. If the skin is crepey and the volume is fine, polynucleotides are. If both are true, most practitioners treat the skin first, because filler under thin skin tends to show every irregularity. Ask directly which order is proposed and why.
Polynucleotides or an under-eye skin booster?
Both are placed superficially and both are given as a course. A hyaluronic acid skin booster hydrates mainly through the gel itself, so its effect shows sooner and fades as the gel is absorbed. Polynucleotides work through your own fibroblasts, so they are slower to show and act on the thinning that caused the problem. Where the skin is very thin, very crepey or reactive, practitioners often start with polynucleotides; where it is mainly dry, a booster may be enough. The assessment should say which your skin is.
Side effects and bruising under the eyes
Numbing cream goes on for around 20 minutes and the injections take 10 to 15, as a series of small, shallow deposits below the orbital rim, placed with a fine needle or a cannula. You leave with small raised bumps that flatten within a few hours, occasionally by the next morning, and most people go straight back to work.
Bruising is the honest caveat. The under-eye is richly vascular and the skin is thin, so bruising here is more likely than on the face or neck and can last the better part of a week. Concealer covers it. If you have something you cannot be bruised for, count back and leave two clear weeks, remembering that the course is three sessions.
Polynucleotides under eyes before and after
Polynucleotides Marylebone shows no before-and-after photographs, because no patient has consented to appear here. What you can expect instead, week by week: small bumps for a few hours after each session; little visible change after the first; better light and a finer texture from around the second, two to three weeks later; and the result judged about eight weeks after the first session, once new collagen has formed.
When you look at a clinic's gallery, check that both pictures share the same room, camera height, light and gaze. The under-eye is the most lighting-dependent area of the face, and a ring light alone can remove a shadow. Ask which week after treatment the second photograph was taken.

Areas treated
What polynucleotides improve under the eyes
- Softens fine crepey texture in the skin under the eye
- Reduces the blue-grey darkness that comes from thin skin
- Thickens the skin so it catches less light in the creases
- Improves hydration in an area that holds very little
- Suits people who have been told they are not ready for filler
- Can be used alongside volume treatment when both are needed
Are polynucleotides safe for you?
For most healthy adults they are low risk. An assessment should rule treatment out, or delay it, if any of these apply:
- Known allergy to fish, since the source material is salmon or trout
- Pregnancy or breastfeeding, where no safety data exists for this treatment
- Active skin infection, inflammation or an open wound in the area
- Active autoimmune disease affecting the skin, without clinical advice first
- Anticoagulant or antiplatelet therapy, which needs assessment before treating
- A prescription acne medicine taken by mouth within the last six months
This is not a complete list. The practitioner who assesses you can decline or postpone treatment for a reason not shown here, and should explain why.
FAQ
Polynucleotides under eyes FAQs
How much do polynucleotides under the eyes cost?
At UNTIL Marylebone, practitioners publish £240 to £350 for one under-eye session, and a course of three or four usually costs about £720 to £1,400. Polynucleotides Marylebone sets none of these fees. Ask the practitioner for the price of the whole course, including any review, in writing.
Do polynucleotides help dark circles under the eyes?
It depends what causes them. Darkness from thin skin letting the vessels show through usually improves, because thickening the skin is what the treatment does. Hereditary pigment and the shadow of a genuine hollow will not. An assessment arranged through Polynucleotides Marylebone should tell you which you have.
How many sessions do under-eyes need?
Three is the usual course, two to three weeks apart, though many practitioners work to four here because the skin is so thin. The result is judged about eight weeks after the first session. Polynucleotides Marylebone suggests asking at assessment whether three or four is planned for you, and why.
Is bruising really that likely under the eyes?
More likely here than anywhere else this treatment is used. The area is richly vascular and the skin is about half a millimetre thick, so a small bleed shows readily and can last up to a week. Polynucleotides Marylebone advises planning the dates around anything you cannot bruise for.
Do polynucleotides soften wrinkles under the eyes?
They soften the fine, crepey lines that sit in thin under-eye skin at rest, usually from around the second session. Lines that appear only when you smile come from muscle movement, which this treatment does not change. Polynucleotides Marylebone suggests asking the practitioner which of the two your lines are.
Can I have polynucleotides and tear trough filler together?
Often, yes, but usually in sequence rather than at the same appointment. Most practitioners treat the skin first and assess the volume afterwards, because filler under thin, crepey skin tends to show irregularities. Polynucleotides Marylebone suggests asking directly which order is proposed for you and why.
What if my eye bags are actually fat pads?
Then this is not your treatment. A herniated fat pad is a structural change that makes a genuine bulge rather than a shadow, and no injectable improves it; the options are surgical. Polynucleotides Marylebone would expect any practitioner to tell you that rather than sell you a course.
How long will the improvement last?
Typically six to twelve months once the full course has settled, because the collagen laid down is your own and ages at the usual rate. Most people who like the result return for one maintenance session in that window. Polynucleotides Marylebone lists published follow-up session prices of £250 to £275 at UNTIL Marylebone.
