Polynucleotides under eyes in London

Crepey skin and fine lines under the eyes

Fine, crinkled lines under the eye come mostly from the skin thinning and losing water rather than from movement. That is the change polynucleotides act on. By prompting the skin's own collagen and elastin and helping it hold water, a course makes the lower lid look smoother and less papery, particularly in daylight, where crepey texture shows most. Deep lines at the outer corner that come from smiling are a different problem, set by the muscle, and polynucleotides soften them only a little.

Dark circles from thin skin

When the skin under the eye is thin, the small vessels beneath it show through as a blue or purple shade, darkest in the inner corner. Thicker, healthier skin hides them better, which is why this type of dark circle responds well to a course. Brown shadowing from pigment responds less, and a shadow cast by a hollow hardly at all. Pressing gently on the area helps tell them apart: a vascular shadow blanches, pigment does not. Dark circles under eyes treatment covers all three types.

A tired, dull look

Under-eye skin that looks dull and dehydrated, and holds concealer badly, often improves before anything else does. Most people notice it around week four, after the second session, as skin that looks brighter and takes make-up more evenly.

Good candidates

People in their late twenties onwards whose under-eye skin has started to look thin, crepey or shadowed, who want it to look healthier without anything that changes the shape of the eye. It also suits people who have had tear trough filler and want the skin over it to improve, and people who were told the under-eye skin is too thin for filler.

Hollow under eyes and deep tear troughs

A hollow is lost volume under the skin, and polynucleotides add none, so a deep tear trough treated with them alone usually looks much the same afterwards. The usual answer to a hollow is filler, sometimes with polynucleotides to improve the skin over it. A practitioner should tell you which you have before you book; hollow under eyes treatment sets out the options.

Eye bags and puffiness

Bags are usually fat pushing forward under the eye, and puffiness is fluid that comes and goes with sleep, salt and allergies. Polynucleotides change neither. Firmer skin can make a mild bag look slightly less obvious, but a pronounced bag is a surgical question, and your GP is the first stop for swelling that is new or one-sided. Under eye bags treatment explains what helps.

They answer different problems. Tear trough filler is a hyaluronic acid gel placed deep under the eye to replace lost volume, and it changes the shape of a hollow on the day. Under-eye polynucleotides are placed in the skin itself, add no volume and improve its quality over about eight weeks.

When filler is the better fit

A visible hollow or a shadow cast by the rim of the eye socket, in someone whose skin is still reasonably thick. Filler under the eye needs a practitioner who treats the area often, because too much, or product placed too shallow, can look puffy or show as a blue tinge.

When polynucleotides are the better fit

Thin, crepey or shadowed skin with little hollowing, skin that is too thin for filler, or someone who does not want any volume added. They are also used before or after filler to improve the skin over it.

When both are used

Some practitioners treat a hollow with a small amount of filler and the skin with a course of polynucleotides. If both are planned, ask which comes first and how far apart, and get the price of the whole plan at the assessment.

The practitioner first looks at the area in good light, often with you sitting upright and then tilting your head, to separate thin skin from a hollow, pigment or a bag. Numbing cream then goes on for around 15 to 20 minutes. The gel is placed with a very fine needle as a line of small deposits along the lower lid, or with a blunt cannula through one or two entry points, which some practitioners prefer because it bruises less. The injecting takes a few minutes per side and the whole visit 30 to 45 minutes. You leave with small bumps under each eye that settle within three days.

Under the eyes, the before and after is a change in the skin you notice most in daylight and in photographs, not a change in shape.

• Days 1 to 3: small bumps along the lower lid, possibly a bruise. Concealer can go on after the first day.
• Week 4: after the second session, the skin looks less dull and concealer sits more smoothly.
• Weeks 8 to 12: crepey lines are softer and the vascular shadow is less obvious. Judge the course here.

Photograph your under-eyes before the first session, facing a window with no make-up, and again at week eight in the same place. Ask the practitioner for their own under-eye before-and-after photographs taken the same way; flattering light and a different head angle can make any under-eye look better.

Bumps and swelling

Small raised bumps along the lower lid are expected and settle in one to three days. Some swelling is common for a day or two and tends to look worse on waking; sleeping with your head slightly raised helps.

Bruising

The skin under the eye is thin and full of small vessels, so bruising is more likely here than anywhere else on the face. It can take a week to fade. Avoiding alcohol, ibuprofen and fish oil for 48 hours beforehand lowers the chance, and a cannula may too.

When to call the practitioner

Swelling that keeps growing, pain that throbs, heat, or any change in your vision needs the practitioner who treated you the same day. Ask before you leave how to reach them out of hours.

Under-eye polynucleotides are published by practices at both clubs. UNTIL Marylebone, 1 Orchard Street, is an 8-minute walk from Bond Street or Marble Arch; UNTIL Soho, 111 Charing Cross Road, is about 150 metres from Tottenham Court Road. Choose either club, or either, on the enquiry form, and read who gives the treatment before you do.
