Thin Lips, Long Philtrum, and the Difference Between Them
Lips that look thin are not always short of volume. Often the space above them is simply doing too much of the talking.

Quick Answer
Why do my lips look thin even after filler?
Because the problem may sit above the lip, not in it.
In Brief
Proportion and volume are two different problems.
The philtrum, the space between nose and upper lip, lengthens gradually with age. As it does, the upper lip rolls inward and shows less of itself, so lips read as thinner even when their actual volume has barely changed. Adding filler to a lip in that situation adds weight without addressing the proportion, which is why some people feel their lips look fuller but not better. Assessing which one you have comes first.

Understanding It
What Changes Above the Lip
The distance from the base of the nose to the top of the upper lip grows over the years, and as it grows the lip itself tends to turn inward and show less pink. The effect is subtle in any single year and obvious across a decade of photographs. It also changes how much of the upper teeth show when you speak or smile, which is often what people notice first without being able to name it.
Volume loss is a separate matter, the lip genuinely holds less than it did, and the two frequently occur together. The plan differs depending on which is dominant, and adding volume to a proportion problem is the most common reason a lip result feels off.
Because the lip sits at the centre of the lower face, it is assessed alongside chin, jaw and mid-face rather than in isolation.
At Consultation
Measuring Before Treating
Lip assessment starts with proportion (the relationship between philtrum length, upper lip show and the lower face as a whole) rather than with lip volume in isolation. Photographs from a decade ago are genuinely useful here if you have them.
We will discuss what your smile does now and what you would like it to do, because upper tooth show is affected by proportion changes and should be an intended outcome, not a surprise.
Where the answer is that your proportion already works, we’ll tell you that instead of taking the booking.

Timeline
Lips Settle Differently From Everywhere Else
Lips swell more than any other area we treat, and they swell immediately. The first twenty-four hours are not representative of anything, and photographs taken then are misleading.
Most swelling resolves within three to five days. By two weeks the result is settled, and that’s the point at which we review and consider whether anything small is needed.
Because lips move constantly, product breaks down faster here than in the cheek. Expect six to twelve months, and expect the second treatment to need less than the first.
Planning
Proportion Before Volume
The most common request is more volume, and the most common actual problem is proportion: the relationship between upper and lower lip, and the distance between nose and lip border.
Adding volume to a lip with a long philtrum often makes the philtrum look longer, because the reference point has changed. Addressing the proportion first, in small amounts, usually achieves what the person came in wanting.
Expect your doctor to discuss what your lips looked like ten years ago, and to plan towards that rather than towards a shape from elsewhere.
A Note
What We’ll Tell You Honestly
Not every lip benefits from treatment, and some faces look better with the lips they have. If your proportion is already good and you have arrived with a photograph of someone else’s mouth, we will have that conversation, not take the booking. A lip that suits your face is the goal, not a lip that suits a reference image.
FAQ
Questions People Ask
Approaches vary in how involved they are. What is right for you, and what it actually entails, is a consultation conversation, not a webpage answer.
Sometimes, and sometimes one makes the other unnecessary. Sequencing matters, and is planned, not bundled.
Proportion changes can affect how much upper tooth shows when you smile, usually the intended effect. This is discussed and planned in advance.
That depends almost entirely on restraint and planning. Our approach is deliberately conservative, and we would rather do less than explain more later.
