This is an excellent question, and I think there is a very important distinction between “lifting the lip” and “increasing vermilion show along the lateral upper lip.” Those are related, but they are not the same thing. The short answer A standard bullhorn (subnasal) lip lift primarily lifts the central upper lip — especially the area beneath the Cupid’s bow. It does not reliably increase vermilion show in the outer third of the upper lip, and in some patients it can actually make the central portion look disproportionately elevated compared with the sides. So the surgeon’s concern is not unreasonable, particularly if you already have minimal lateral vermilion exposure. Why this happens The bullhorn excision removes skin directly under the nose. The greatest lifting effect occurs where the excision is widest — usually the central philtral region. That tends to: shorten the philtrum, increase central tooth show, enhance the Cupid’s bow, and create more central vermilion eversion. The farther you move laterally toward the commissures, the weaker the lifting effect becomes. What your surgeon means by a “steep slope” If the center of the lip is lifted significantly but the lateral upper lip remains relatively hidden, the upper lip can develop a “gull-wing” or overly peaked appearance: prominent center, insufficient side support, and a sharper transition from the philtrum to the lateral lip. That is often what surgeons are trying to avoid when they mention an unnatural slope. Do you need a corner lip lift? Probably not necessarily, based on what you’re describing. A corner lip lift is designed primarily to elevate the oral commissures (the corners of the mouth). It is most useful when someone has: downturned mouth corners, a sad or tired resting expression, or age-related descent of the commissures. You specifically said: “I’m not looking for the corners of my mouth to be raised.” That’s an important clue. If your goal is more visible lateral upper-lip vermilion, a corner lift may not be the ideal procedure, because its main effect is on the mouth corner position, not on the entire lateral vermilion border. Why some surgeons combine them A combined bullhorn + corner lip lift can create a more evenly elevated upper-lip contour, but it is usually chosen when the patient has both: limited lateral vermilion show, and mild commissure descent. The trade-off is that a corner lift leaves additional scars at the mouth corners, which many surgeons (and many patients) are understandably cautious about. That is one reason you may find fewer surgeons in the UK offering the combination routinely — the demand is relatively small, the procedure is technically more nuanced, and the scar visibility at the commissures can be difficult to predict. If your goal is lateral fullness rather than corner elevation I would think about these options: 1. Conservative HA filler focused on the lateral upper lip This is often the least invasive way to test whether increased lateral vermilion show actually gives you the look you want. Tiny amounts placed in the outer upper lip can improve side-profile visibility without altering the mouth corners. 2. Modified subnasal lip lift Some surgeons perform a more laterally extended bullhorn design to distribute the lift more evenly across the upper lip rather than concentrating it centrally. This requires careful planning to avoid nostril distortion. 3. Vermilion advancement (mucosal advancement) For patients whose main issue is insufficient visible red lip, a vermillion advancement procedure can increase upper-lip show along the entire border, including the lateral portions, without necessarily changing the mouth-corner position. The scar sits at the vermilion-cutaneous junction, so it has its own pros and cons, but it is often a better match for the specific problem you’re describing than a corner lift. My honest impression From your description alone, I would be more suspicious that your primary issue is inadequate lateral vermilion show rather than true commissure descent. That means: A standard central bullhorn alone could potentially over-emphasize the Cupid’s bow. A corner lip lift might be more than you actually need. A modified bullhorn design, selective lateral lip filler, or vermilion advancement may be more anatomically targeted to your stated goal. The surgeon’s warning that a central-only lift could create a disproportionately elevated center is quite plausible, especially in patients with naturally thin lateral upper lips. However, it does not automatically mean that a corner lip lift is required. The key question is whether the corners are downturned (which you deny) versus whether the lateral vermilion is simply not visible enough. If I were counseling a patient with your goals, I would frame it this way: Want a stronger Cupid’s bow and shorter philtrum? → Bullhorn lip lift Want the outer upper lip to show more red lip? → Lateral filler or vermilion advancement Want the mouth corners to turn upward? → Corner lip lift Based on what you’ve written, I suspect you fall much more into the second category than the third, which is why I would be cautious about assuming that a corner lip lift is the necessary solution for achieving better lateral upper-lip definition and visibility.
