Am I a Candidate for a Lip Lift? How Philtrum Length Is Measured

How do I know if I need a lip lift?

The measurement that matters is philtrum length — the distance from the base of the nose to the top edge of the upper lip, measured down the midline with your face relaxed. As a general reference, distances around 15 mm or less in women and 18 mm or less in men read as youthful. Meaningfully longer than that, and the upper lip begins to look thin and the mouth heavy, regardless of how much volume the lip itself has.

But the number is a starting point, not a verdict. What determines candidacy is how that distance relates to the rest of your face.

How the measurement is taken

The face must be relaxed, lips lightly together, not smiling and not pursed. The measurement runs from the subnasale — where the base of the columella meets the upper lip — to the vermilion border at the midline. It is recorded in millimetres.

Two other observations are taken at the same time:

• Tooth show at rest. How much of the upper incisors is visible with the mouth relaxed. In a youthful face a few millimetres show; when the philtrum lengthens, the teeth disappear entirely.
• Gum show on smiling. How much upper gum is exposed in a full smile. This one is a constraint rather than an indication — a lip lift increases gum show, so a patient who already shows a lot of gum is generally not a candidate.

Lip lift or lip filler?

This is the most common source of confusion, and the two are not interchangeable.

A lip lift changes proportion. It shortens the nose-to-lip distance and rolls more of the pink vermilion into view. The lip appears fuller because more of it is visible, not because anything has been added.

Filler changes volume. It makes the existing lip bigger. If the underlying problem is a long philtrum, adding volume produces a lip that is larger but still sits too far from the nose — and repeated filler over years tends to push the lip forward rather than upward, which reads as heavy rather than youthful.

If your own description of the problem is "my top lip has disappeared", that is a proportion complaint, and filler is the wrong tool for it.

Who tends to be a good candidate

• A philtrum that is long relative to the rest of the face
• Little or no upper tooth show at rest
• A modest gum show when smiling
• Good general health and a non-smoker, or willing to stop well before surgery
• An expectation framed around proportion and balance

Who tends not to be

• An already short philtrum
• Significant gingival show on smiling
• Active smoking, which impairs healing at the incision
• Wanting more volume rather than better proportion — filler may be more appropriate
• Very recent filler in the upper lip, which distorts the assessment

The scarless approach

A traditional bullhorn lip lift places an incision at the base of the nose. Well-executed, it heals discreetly; but it is an external scar in a highly visible location, and concern about it is the single most common reason patients hesitate.

Dr. Dogan's scarless technique achieves the same shortening without that incision, working beneath the skin surface. For patients who want the proportional change but not a visible line under the nose, this is what makes the procedure viable.

Final takeaway

Ask for your philtrum to be measured, and ask what the number means for your face specifically rather than against a general standard. A lip lift is a proportion operation, and the patients who are happiest with it are the ones who wanted proportion rather than volume in the first place.
