Treatment guide

Lip filler adds hyaluronic acid gel to alter volume, shape, definition or symmetry. It can restore lost fullness, improve balance between upper and lower lip, define a border or support a downturned corner. It cannot change the skin around the mouth or lift a heavily descended upper lip.
A lip is not a single structure. There is the red vermilion you see, the wet mucosa inside, the vermilion border where red meets skin, the philtral columns running down from the nose, the cupid's bow, and the skin of the upper lip between the nose and the border. Ageing and genetics affect each differently.
Someone whose complaint is that their upper lip has disappeared may have lost vermilion volume, or may have a lengthened upper lip that has rolled inward, which is a different problem with a different answer. Adding volume to a lip that has rolled under pushes it forward rather than out, and produces the projecting shelf that people recognise immediately as work.
A good assessment looks at the proportion between upper and lower lip, the height of the upper lip skin, how much tooth shows when you smile and speak, the position of the corners, and the support underneath from the chin and the teeth. It also looks at the rest of your face, because a lip cannot be designed in isolation.
Conservative. A small volume, placed to improve shape and definition rather than to add obvious size, then reviewed at two weeks and built on if you want more. This approach costs more in total than one large treatment and it is still the right one, because you can add and you cannot easily take away without dissolving everything and starting again.
You can always add more in a fortnight. You cannot un-see a lip that is too big for your face at a wedding on Saturday.
Techniques vary and each is a means to an end rather than a brand of result: linear threading along the border for definition, small aliquots in the body of the lip for volume, support at the corners, and occasionally a small amount at the philtral columns to restore shape. The point of asking what your practitioner intends to do is not to audit their technique but to hear whether they have a plan specific to your mouth.
Lips swell more than anywhere else on the face. The first twenty four to forty eight hours commonly produce a result that looks nothing like what was intended, and this is normal. People who panic on day two are usually looking at swelling, not filler.
Do not book lip filler in the week before an event. Two to three weeks is a sensible minimum, and four is better if you have not had it before and do not know how you swell.
Filler migration means product that has moved beyond the vermilion border into the skin above the lip, producing a soft shelf, a loss of definition of the border, or a characteristic dark shadow line. It is one of the most common reasons people seek dissolving.
Contributing factors include placing product too superficially or too close to the border, treating too often before previous product has broken down, using a volume the tissue cannot accommodate, and repeated massage or pressure. It is more visible in people with a short upper lip.
If you have had several rounds of lip filler over a few years and the border is losing definition, the correct next step is usually assessment for dissolving rather than another syringe. A practitioner who suggests dissolving is not talking themselves out of work; they are giving you the answer that will actually improve the result.
There is no legal barrier in the UK to a person with no clinical training injecting filler into your lips. Training courses lasting a single day exist and are advertised openly. This is the reality of the market you are shopping in, and it is why the practitioner is the product.
A clinic that pressures you toward a decision in the room is telling you what it values. The clinic selection guide covers verification in detail.
Lip filler is usually priced by volume, which encourages comparison on the wrong measure. What you are paying for is assessment, product selection, technique, a two-week review, and a practitioner who can obtain and administer the reversal agent within hours if needed.
The cost guide sets out every variable without quoting a figure, because a number without those variables attached is meaningless.
Common questions
Commonly six to twelve months. Lips move constantly, which speeds breakdown, so they usually last less time than filler in static areas such as the cheek.
That is a decision about volume and placement, not an inevitable outcome. A conservative first treatment reviewed at two weeks is the reliable route to a result that reads as your own mouth.
Significant swelling for the first day or two is normal and is not the result. Judge the outcome at two weeks.
Yes, if it is hyaluronic acid. Hyaluronidase is used, it is a prescription-only medicine, and the area is usually left to settle for a fortnight before any new treatment.
Lips are sensitive. Topical anaesthetic is standard and many products contain lidocaine. Most people describe it as uncomfortable rather than painful.
Usually yes, but tell the practitioner. Injection can trigger an outbreak and antiviral prophylaxis started before treatment reduces that risk substantially.
At least three to four weeks, and preferably not for the first time. Swelling and bruising are unpredictable and you want the option of a review.
