You may notice your lips look thinner in photographs than they used to, or that one side has always sat slightly fuller than the other. These are quiet changes that develop gradually rather than suddenly. Lip filler restores volume, softens asymmetry or subtly redefines shape, using hyaluronic acid products that integrate naturally with the surrounding tissue.
Every lip filler treatment at Array Aesthetics is led inside our RQIA-regulated Belfast clinic by a doctor-led team.

Lip filler is a hyaluronic acid-based injectable used to restore volume, correct asymmetry or refine the shape of the lips. Many patients tell us they don't want anyone to notice they've had lip filler; they want their lips to look healthier, more balanced or more defined. That conservative approach guides every treatment at Array. We use Belotero, manufactured by Merz Aesthetics, for its softness and natural feel once integrated, with results typically lasting six to twelve months.
Lip filler is injected using either a fine needle or a blunt cannula, depending on the technique your clinician judges most appropriate for your anatomy. The hyaluronic acid is placed strategically to add volume, refine outline or correct asymmetry rather than uniformly along the length of the lip. Treatments take around thirty minutes and are performed after a topical anaesthetic has been applied. Lips usually feel firmer than expected during the first few days. As swelling settles and the filler integrates with the surrounding tissue, they gradually soften until the final result becomes visible at around two weeks.
Lip filler is the right treatment when the goal is to restore volume, correct asymmetry or refine shape. The most important element is not the product but the injector's judgement about how much to place, where to place it and when to stop. Overfilled lips are almost always the result of technique. Occasionally, the right recommendation is to use less filler than a patient expected, or not to treat at all until facial proportions can be assessed more broadly. That approach often produces the most natural long-term results.
Lip filler at Array is led by co-founder Dr Chris Hutton (GMC: 7039324), an experienced lead injector and Merz Aesthetics training partner, alongside Nurse Practitioner Trish Short (NMC: 19I0787N).
Lip filler is not the only way to enhance the lips. A lip flip uses a small dose of botulinum toxin to relax the muscle around the upper lip, which creates the illusion of a slightly fuller upper lip without adding volume. It suits patients wanting a very subtle change or those whose upper lip appears thin only when they smile. Surgical options such as a lip lift are more invasive and permanent and typically suit patients whose concerns extend beyond volume.
You are a candidate for lip filler if your goal is added volume, corrected asymmetry or a refined lip shape, and you want a result that can be adjusted at future appointments. A lip flip may suit if you want a subtle change with no added volume. A surgical lip lift is appropriate when the concern is upper lip length rather than lip volume itself.
Lip filler pairs well with other treatments that address the perioral area and the surrounding face. Anti-wrinkle injections around the lip line can soften vertical smoker's lines, while a lip flip can subtly increase the visible show of the upper lip alongside filler volume. Some patients also combine lip filler with treatments to the chin, cheeks or jawline to bring facial proportions into balance. Your clinician will plan these together rather than in isolation, so the overall result is proportionate.
Lip filler treats loss of natural lip volume, asymmetry between the upper and lower lip or between the left and right sides, softened definition of the vermilion border and fine vertical lip lines. It is used to enhance shape and volume subtly, not to dramatically transform the appearance of the lips.
Lip filler is placed within the body of the upper and lower lips, along the vermilion border where lip meets skin, or at specific points to correct asymmetry. Some techniques focus on volume, others on definition. The distribution is planned at consultation based on your anatomy and goals.
Lip filler produces immediate results in volume and shape, though the final look is best assessed once initial swelling settles at around two weeks. Results typically last six to twelve months, and the treatment is reversible if you choose to change or correct the outcome. Small refinements can be added at follow-up.
A topical anaesthetic is applied before treatment to numb the lips. Injections take around 30 minutes, and most patients describe them as pressure rather than sharp pain. Lips will feel firm and appear swollen immediately afterwards, with the true result apparent once swelling settles over ten to fourteen days.
Lip filler is safe when performed by an experienced clinician using established hyaluronic acid products. Common side effects are short-lived swelling, bruising or firmness. Rarer complications such as vascular occlusion require a medical injector trained in emergency reversal, which is why lip filler should be delivered inside an RQIA-regulated medical clinic.
Avoid touching or pressing on your lips for the rest of the day, and skip strenuous exercise, saunas and hot showers for twenty-four hours. Sleep on your back for the first night if possible. Avoid alcohol and dental work for two weeks. Bruising and swelling will settle progressively over the days that follow.
Not when placed conservatively by an experienced clinician. Overfilled lips are almost always the result of too much volume or poor placement rather than the product itself. It's easier to add a little more at your two-week review than to correct lips that have been overfilled from the outset.
Yes. Hyaluronic acid fillers can be dissolved using hyaluronidase, an enzyme that breaks down the HA in the tissue. This is offered at Array as a standalone treatment or in the rare event of complications.
Lips will feel firm and look larger than the final result for the first two to three days. Most swelling settles within a week, with the true shape and softness apparent from around two weeks.
At Array, all patients receive follow up as required. Contact a member of our team at enquiries@arrayaesthetics.com or call 028 9457 1840 to arrange your review appointment.
At Array we use a variety of fillers but mainly Belotero by Merz.
Yes. Many patients begin conservatively with 0.6ml before deciding whether more volume is needed. Because a review appointment is included at two weeks, any further refinement can be discussed once swelling has settled.
Yes. Lip filler and anti-wrinkle treatments are commonly combined for a balanced overall result. A lip flip using botulinum toxin can also complement filler by subtly increasing upper lip show without added volume.
Lip filler treatments last between 6-12 months
