In short. A photograph that is not your anatomy, a lip already over-filled, and a request made to satisfy somebody else: the requests worth declining.

Key points

  • An assessment which establishes that the lip is ordinary for the face, that the change noticed is lip length or a matter of what is behind the lip, that the lip is already at its limit, or that the expectation is a lasting result has done its job.
  • Ending there is not a refusal to treat; it is the assessment working.

Some requests for lip treatment should be declined, and the reasons are not about the patient being unsuitable in a general sense. They are about the request itself: where it comes from, what it is pointed at, and what the person asking expects it to do.

A photograph that is not your anatomy

The same amount of material reads differently on different faces, because a lip is read against the length of the upper lip, the teeth, the chin and the rest of the mouth. A lip reproduced from somebody else's photograph on your face is a borrowed feature, and it usually looks like one. The honest version of this request is a description of what you see in your own mirror.

A lip that is already over-filled

Where the border has been filled across, the bow has flattened or the lip projects in profile, more material makes every one of those worse. The answer is usually less, or nothing, and where the filling has been going on for years it may be a plan to stop rather than a plan to correct. Tissue that has been stretched does not return to its earlier shape on its own.

A request made for somebody else

A partner, a parent, an employer or a photograph of a stranger is not a reason to have a lip injected. Where the request is made to please someone else, the person who lives with the result is the one who did not ask for it, and dissatisfaction follows the mismatch rather than the result.

The appointment that should end with nothing injected

An assessment which establishes that the lip is ordinary for the face, that the change noticed is lip length or a matter of what is behind the lip, that the lip is already at its limit, or that the expectation is a lasting result has done its job. Ending there is not a refusal to treat; it is the assessment working.

Expectations that do not survive the first session

A request that the result be lasting, that the lip look the same in every photograph, or that a single session resolve a shape that has been building for years is met by no material. It is kinder to establish that before the injection than after a third one. So is the request made in a hurry before a fixed date, because a lip that is swollen for a week is a poor preparation for a wedding.

The requests to decline

  • A shape taken from another person's photograph and asked for as a likeness.
  • A lip that is already over-filled, or a request to keep adding to one.
  • A change wanted for somebody else, or an expectation of a lasting result.

The candidacy assessment that produces the same answer from the other direction is described in Is Lip Filler the Right First Step? A Candidacy Check, and what to do instead is set out in Alternatives to Lip Filler, From Proportion to Surgery.

Frequently asked questions

Can a clinic refuse to treat my lips?

Yes, and it belongs to the assessment rather than being a judgement about you. The request may be pointed at something volume cannot change, or the lip may already be at its limit, or the expectation may be one no material meets. Ending an appointment there is the assessment working rather than a refusal to treat.

I want my lips like a celebrity's. Is that unreasonable?

The request is common and it is not unreasonable as a starting point. The difficulty is that the same amount of material reads differently on a different face, because a lip is read against the nose, the teeth and the chin around it. Ask instead what change in your own lip would produce the look you are describing.

Is it worth having lip filler before a big event?

Usually not within a few weeks of one. The lip is at its most distorted for three days and visibly swollen for about a week, and the shape is not settled until two to four weeks. A date that matters should sit at least a month after treatment rather than inside the recovery.

Risks & Limitations

  • Vascular occlusion is a time-critical emergency, and the lip is a small area whose arteries vary in course between people and between the two sides. Severe pain out of proportion to the injection, or tissue turning white, grey, mottled or dusky, requires immediate assessment.
  • Every filler result is temporary, and the lip fades unevenly: the border often loses definition before the body of the lip flattens. Maintenance treatment is required to keep a result continuous.
  • The lip tolerates very little added volume before the change reads as treated, and only the reversible class of material can be broken down at all. A stretched vermilion and a border that has been filled across do not revert when the material goes.
  • Lumps, nodules, asymmetry and delayed inflammatory reactions can occur, and an injection commonly reactivates cold sores in someone who has had them before. The lip is the most mobile injected site, so material inside it is being deformed continuously.

When to Seek Care

  • Any change in vision, including blurring or a patch of lost sight — seek emergency care immediately.
  • Severe pain out of proportion to the injection, or pain that is worsening rather than settling.
  • Tissue turning white, grey, mottled or dusky anywhere on or around the lip.
  • Swelling that is increasing after the third day rather than settling, or fever with spreading redness, warmth or discharge.
