Lip Filler in Marylebone, London
Shape, border and proportion, from £250 at 4 Baker Street

Lip filler at Mesglo: the direct answer
Lip filler is a hyaluronic acid gel placed in small, measured amounts to change the shape, border and proportion of the lips rather than simply to make them larger. At Mesglo, treatment starts from £250, takes thirty to forty five minutes at our clinic at 4 Baker Street in Marylebone, and is carried out by Rahena, who holds the Level 7 Diploma in Aesthetic Practice and performs every treatment herself. You see a change as you leave; the settled result is assessed at two weeks.
Lip filler, lip fillers and lip injections all describe the same treatment. The approach here is conservative and built on an assessment of your own lip anatomy, because the amount of product that suits one mouth will look wrong on another. If the assessment shows that your lips are not the right place to treat, we will say so and explain what would help instead. That is a normal outcome of a consultation, not a failed one.

How lip filler works in the lip
Hyaluronic acid is a sugar molecule your own skin already makes. It holds water, and that is the whole mechanism: a gel of cross linked hyaluronic acid placed in the lip draws water to itself and occupies space, so the tissue sits fuller and the border sits more clearly than it did. Nothing is cut and nothing is implanted permanently. The body breaks the gel down over months with its own enzymes until the lip returns to how it started.
Lips need a soft, loosely cross linked gel. A firm gel resists being squashed, which is exactly what you want deep on bone for a chin or a jawline, and exactly what you do not want in a structure that moves every time you speak, eat and smile. Choosing the wrong firmness is one of the commonest reasons lips look and feel overdone rather than fuller.
The four things assessed before anything is injected
Lip treatment is a proportion problem before it is a volume problem. Four things decide the plan.
- The ratio of upper to lower lip. A balanced mouth usually carries more volume in the lower lip than the upper. Filling both equally is what flattens a mouth and makes it read as treated.
- The vermilion border and the cupid’s bow. Definition here is often what people are actually asking for when they ask for fuller lips, and it takes very little product placed accurately.
- Lip height and the distance to the nose. A long upper lip with a thin red portion behaves differently from a short one, and adding volume to the first can make it look heavier rather than fuller.
- Support from behind. Lips sit on teeth and in front of a chin. A flat side profile is sometimes a chin question rather than a lip question, and chin and jawline filler is the treatment that answers it.
Smokers’ lines, loss of skin quality around the mouth and a downturned corner are related concerns that are not always solved by filling the lip body, and each is discussed on its own terms at consultation.
Lip filler or Skinfill Bacio: which one your lips need
These are different treatments and the distinction decides whether you will be happy with the result.
Lip filler is a shaped gel. It has a position and a shape, and it is the right treatment when the lips need volume, projection or a defined border they do not currently have.
Skinfill Bacio is a hydrating lip treatment, also from £250. It improves the quality, hydration and surface of the lip rather than building a shape, so it suits lips that are dry, lined or dehydrated but not short of volume, and people who do not want their lip shape changed at all.
Some plans use one, some the other, and some use both for different jobs. The choice is made at the assessment, not from a price list.
How long lip filler lasts, and what shortens it
Lip filler typically lasts six to twelve months. Lips are the shortest lived filler result on the face, because the area moves constantly and movement breaks the gel down faster. For comparison, cheeks and midface usually hold twelve to eighteen months and structural work on a chin or jawline can hold up to two years.
Those are ranges rather than promises. A fast metabolism, regular high intensity exercise, heavy sun exposure and smoking all shorten the life of a result. A review at two weeks and a planned top up before the result has fully gone keeps the shape consistent and usually needs less product than starting again.
The first two weeks: swelling, bruising and settling
You will see a change as you leave, because the gel occupies space immediately. What you see on day one is not the result. Lips swell more than any other area of the face: swelling peaks in the first twenty four to forty eight hours, settles over the following week and has usually resolved by two weeks, which is when the outcome is assessed and when photographs are taken.
Bruising is possible anywhere a needle enters skin and is more likely in lips than on cheeks or a jawline. It typically fades within a week and covers easily. Small firm areas that soften, tenderness and a slightly uneven feel in the first days are all normal. Avoid strenuous exercise, alcohol, saunas and steam rooms for twenty four hours, and avoid massage or facials over the area for two weeks. If you are prone to cold sores, tell us at consultation, because treatment can bring an outbreak on and that is managed in advance.
Plan around your diary rather than the other way round: two weeks before an event, not two days.
Risks, side effects and how they are reduced
Every injectable treatment carries risk, and a clinic that does not discuss it is not giving you what you need to consent properly.
Common and self limiting: swelling, bruising, redness at injection points, tenderness and short lived asymmetry while swelling settles.
Uncommon: a firm area or nodule that needs massage or, occasionally, dissolving; a result that is not what you wanted, which with hyaluronic acid can be adjusted or reversed; a cold sore outbreak in someone who carries the virus; delayed inflammatory swelling, which can appear weeks or months later, often after an infection or a vaccination, and is managed medically.
Rare and serious: vascular occlusion, where product interrupts the blood supply. It is reduced by anatomical knowledge, slow injection, aspiration where appropriate and small volumes, and it is treated urgently if it happens. You are given the clinic’s contact details and told exactly what to look for and when to call before you leave.
Dissolving and adjusting lip filler
Because only hyaluronic acid fillers are used here, lip filler can be broken down with an enzyme called hyaluronidase, usually within a day or two. That reversibility is the main safety advantage of hyaluronic acid over permanent and semi permanent products, which is why those are not offered.
Dissolving is assessed rather than sold. It is appropriate for a firm nodule, for product in the wrong place, for migration above the border, or for a shape you no longer want, and it is assessed at a consultation first, including where the original treatment was carried out elsewhere. Hyaluronidase itself carries a risk of allergic reaction and removes your own hyaluronic acid alongside the gel, so it is not a routine step and the lips are allowed to settle for several weeks before anything is replaced.
If you are worried about a recent lip treatment, whoever performed it, message the clinic on WhatsApp or call rather than waiting for a routine appointment.
When we will not treat your lips
Treatment is declined, or deferred, if you are pregnant or breastfeeding; if you have an active cold sore, skin infection or inflammatory condition at or near the lips; if you have had a recent vaccination or are unwell with an infection; if you have a known allergy to hyaluronic acid or lidocaine; if you have an autoimmune or connective tissue condition your specialist has advised against injectables with; or if you are taking a medication that makes the treatment unsafe.
We also decline on judgement rather than contraindication. If the concern you describe will not be improved by lip filler, if the lips already hold as much product as they can carry well, or if what you are asking for would not suit your face, we will say so and explain what would help instead.
What lip filler costs at Mesglo, and what the price covers
Lip enhancement at our Marylebone clinic starts from £250, and Skinfill Bacio also starts from £250. The final figure depends on the plan and on how much product it needs, and it is confirmed at your consultation before anything is agreed, so you never arrive at a price on the day.
The fee covers the assessment, the plan, the product, the treatment itself, aftercare advice and the review appointment where the settled result is checked. Current prices for every treatment are listed on our booking page, there is a fuller explanation of what moves the figure in our guide to lip filler prices in Marylebone, and you are welcome to ask on WhatsApp before you book.
A quote well below the London range is worth asking questions about: who is injecting, what product is being used, and what happens if something goes wrong.

Questions people ask
How long do lip fillers last?
Lip filler results typically last 6-12 months, depending on the product used, your metabolism, and lifestyle factors. Many clients find that results last longer with regular maintenance treatments.
Will lip fillers look natural?
At Mesglo London, natural-looking results are our priority. We use a conservative approach, building volume gradually and respecting your natural lip proportions. The goal is enhancement, not transformation.
Is lip enhancement painful?
We apply topical numbing cream before treatment, and our premium fillers contain lidocaine for additional comfort. Most clients describe the sensation as mild pressure rather than pain.
What is the recovery time?
You may experience mild swelling and bruising for 24-72 hours. Most clients return to normal activities immediately, though we recommend avoiding strenuous exercise for 24 hours.
Can lip fillers be reversed?
Yes, hyaluronic acid fillers can be dissolved using hyaluronidase if you're unhappy with the results. This is one of the key safety benefits of HA fillers.
How much does lip filler cost in Marylebone?
Lip enhancement at Mesglo in Marylebone starts from £250, and Skinfill Bacio also starts from £250. The final price depends on the plan and the volume of product it needs, and it is confirmed at your consultation before anything is agreed. The fee covers the assessment, the product, the treatment, aftercare and the review appointment.
How much filler will my lips need?
Usually less than people expect. Lip treatment is a proportion problem before it is a volume problem, and a small amount placed accurately on the border or in the lower lip changes a mouth more than a larger amount spread evenly. The volume is decided at the assessment and built over more than one session where that is the better route.
Can lip filler be dissolved?
Yes. Only hyaluronic acid fillers are used here, so the gel can be broken down with an enzyme called hyaluronidase, usually within a day or two. Dissolving is assessed at a consultation first, including where the original treatment was carried out elsewhere, and the lips are allowed to settle for several weeks before anything is replaced.
What is the difference between lip filler and Skinfill Bacio?
Lip filler is a shaped gel that adds volume, projection or a defined border. Skinfill Bacio is a hydrating lip treatment that improves the quality and hydration of the lip without building a shape, so it suits lips that are dry or lined rather than short of volume. Some plans use both for different jobs.
How long before an event should I have lip filler?
Two weeks, not two days. Swelling peaks in the first twenty four to forty eight hours and has usually resolved by two weeks, which is when the settled result is assessed and when any small adjustment is made.
I have had lip filler somewhere else. Can you treat me?
Yes, after an assessment. What is already in the lip changes what should be added, and in some cases the right first step is to let existing product settle or to dissolve it rather than to add more. That is discussed at the consultation before anything is agreed.
