In short. What a lip assessment examines, and the answers that should end a first appointment with nothing injected rather than with a plan.
Key points
- Which change is present in your lip — lost volume, lost border definition, lip length, or something behind the lip.
- Whether an injection reaches it.
- What the alternatives are, including doing nothing.
A first appointment about the lips is an assessment, and the general question of whether an injectable suits you at all is answered on the dermal filler pages. What a lip consultation decides is narrower: what in this particular lip settles whether the treatment does what you hope, and what should end the appointment with nothing injected.
What the assessment examines
The first thing established is how much vermilion is visible at rest, because a lip that shows little can look thin while holding a normal amount of tissue. The upper lip is then measured from the base of the nose to the border, and a long upper lip reads as a thin one without being one. The border is examined for the roll that gives a lip its definition, and the two sides are compared, because most lips are asymmetric already. Finally the lip is watched while you smile and speak, because how it behaves in motion decides how much material it carries.
The lip is not assessed on its own
The teeth, the smile and the position of the chin decide how much lip is visible and how the mouth sits. Where those are the reason the lips look small, adding volume in front of them makes the mouth protrude rather than balancing it, and the honest answer is a dental, orthodontic or jaw opinion.
What you should leave knowing
Which change is present in your lip — lost volume, lost border definition, lip length, or something behind the lip. Whether an injection reaches it. What the alternatives are, including doing nothing. An appointment that produces none of those has produced a quotation rather than an assessment.
The answers that should end the appointment
A lip that is ordinary for the face it belongs to is the commonest reason to do nothing. A request for a shape taken from another person is the second, because the same amount of material reads differently on different faces and a lip copied from a photograph looks borrowed. So does a request made to satisfy somebody else, and so does an expectation that the result is lasting.
Who should wait rather than cancel
An active cold sore is a reason to wait, because an injection commonly reactivates it. So is any infection in or around the mouth, and recent dental work in the same part of the face. Pregnancy and breastfeeding are reasons to postpone an elective treatment. A bleeding disorder, or medication that affects clotting, needs discussing before anything is scheduled.
Ask for a different conversation if
- You are told the result is lasting, or that a lip cannot be over-filled.
- The plan is described in amount only, with nothing about the plane or the border.
- Nobody asks about cold sores, dental work, medication or previous filler.
Where the honest answer is that the lip is not the problem, the reasoning is set out in When the Lips Are Not the Real Problem, and the requests that should be declined in When the Answer to Lip Filler Is No.
Frequently asked questions
How do I know whether my lip is thin, or just long?
Ask what the distance is from the base of your nose to the upper border. A lip can hold an ordinary amount of tissue and still read as thin, because that distance is long and less of the lip is visible. Where that is the finding, volume makes the lip project forward without making it look taller, and the operation that shortens the distance is a lip lift.
Should the first appointment include an injection?
Usually not. An assessment produces a plan, and a plan is easier to consider on a day when nothing has been injected and nothing is swollen. Where the answer turns out to be that the lip is not the problem, treating it on the same visit removes any chance to say so before the needle is opened.
What makes an appointment end with no injection?
A lip that is ordinary for the face it belongs to, a shape wanted from somebody else's photograph, a request made to satisfy another person, an expectation of a lasting result, and an active cold sore or infection in or around the mouth are all answers that end the appointment. So are pregnancy, breastfeeding and recent dental work.
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.
