A lip lift with Botox is a nonsurgical technique where small amounts of botulinum toxin are injected along the upper lip border to create the appearance of a fuller, slightly lifted upper lip. Unlike a surgical lip lift, which permanently removes skin between the nose and lip, the Botox version works by relaxing the muscle that pulls the upper lip downward, allowing it to gently flip upward and show more of the pink lip tissue. The effect is subtle, temporary, and typically lasts two to four months.
How the Botox Lip Flip Works
The procedure is commonly called a “lip flip” rather than a lip lift, and the distinction matters. A surgical lip lift shortens the space between the nose and the lip (called the philtrum) by removing a strip of skin. A Botox lip flip doesn’t change any structures. Instead, it targets the orbicularis oris muscle, the circular muscle that surrounds your mouth and controls lip movement.
When this muscle contracts, it naturally pulls the upper lip inward and slightly downward, hiding some of the vermilion (the colored part of the lip). By injecting a very small dose of Botox into the upper portion of this muscle, just along the lip border, the muscle relaxes enough to let the lip roll gently outward. The result is a subtle “flip” that exposes more of your upper lip without adding any volume.
What the Procedure Looks Like
A lip flip is one of the quickest cosmetic procedures available. The entire appointment typically takes about 10 minutes. A practitioner injects small amounts of Botox into four to six points along the upper lip, usually centered around the cupid’s bow and extending toward the corners. The needles used are very fine, and most people describe the sensation as a brief pinch at each injection site. Some practitioners apply a numbing cream beforehand, though many patients skip it because the discomfort is minimal.
There’s essentially no downtime. You might notice small bumps or slight redness at the injection sites for an hour or so, but most people return to normal activities immediately. Results aren’t instant, though. The Botox takes about three to five days to start working, with the full effect visible around 10 to 14 days after treatment.
Lip Flip vs. Lip Filler
People often confuse a Botox lip flip with lip filler, but they do very different things. Filler (typically hyaluronic acid) physically adds volume to the lips, making them plumper and larger. A lip flip adds zero volume. It simply changes the position of the lip so more of its natural surface is visible. Think of it as revealing lip tissue that was already there but tucked inward.
A lip flip works best for people who already have a reasonable amount of lip tissue but feel their upper lip disappears when they smile, or who want a slightly more defined lip border without the look of filler. People with very thin lips may not see a dramatic difference from a lip flip alone, since there’s limited tissue to “flip” outward. In those cases, combining a lip flip with a small amount of filler can achieve both the lifted shape and added fullness.
- Botox lip flip: Relaxes the muscle, reveals more lip, adds no volume, lasts 2 to 4 months, costs roughly $100 to $300 per session.
- Lip filler: Physically adds volume, shapes and plumps the lip, lasts 6 to 12 months or longer, costs roughly $500 to $1,000 or more per syringe.
Who Gets the Best Results
The ideal candidate for a lip flip is someone whose upper lip curls inward or flattens noticeably when smiling. This happens because the orbicularis oris muscle is particularly strong in some people, pulling the lip tightly against the teeth. Relaxing that pull can make a visible difference in how much lip shows during a smile.
It also works well for people who have a “gummy smile,” where the upper lip rises too high and exposes a significant amount of gum tissue. By relaxing the muscles that elevate the lip, Botox can reduce how far the lip pulls up, keeping more gum covered. This application sometimes involves injecting slightly different muscles on either side of the nose in addition to the lip border itself.
People who rely heavily on lip muscle control, like musicians who play wind instruments or brass, should be cautious. Because the procedure relaxes the muscle around the mouth, it can temporarily affect your ability to pucker tightly, drink through a straw, or whistle. These effects are mild for most people but can interfere with activities that require precise lip control.
Potential Side Effects
Because the doses used for a lip flip are very small (typically 4 to 8 units of Botox, compared to 20 to 40 units for forehead lines), side effects tend to be minor. The most common complaints include slight bruising at the injection sites and a feeling of mild strangeness around the mouth as the muscle relaxes over the first week.
Some people find that certain sounds or facial expressions feel slightly different while the Botox is active. Drinking from an open cup usually isn’t affected, but sipping through a straw can feel awkward in the first couple of weeks. Pronouncing certain letters, particularly those that require a tight lip seal like “P” and “B,” may feel subtly different. These effects are temporary and fade as the Botox wears off.
Asymmetry is possible if the Botox is placed unevenly or if one side of the muscle responds more strongly than the other. A skilled injector can often correct minor asymmetry with a small touch-up injection at a follow-up visit.
How Long Results Last
A Botox lip flip has one of the shorter durations of any Botox application. Most people see the effect fade within two to three months, with some lasting up to four months. This is shorter than Botox treatments in the forehead or around the eyes, partly because the mouth area is one of the most active muscle groups on the face. You use your orbicularis oris constantly throughout the day when talking, eating, and making expressions, which speeds up how quickly the Botox is metabolized.
The upside of the short duration is that if you don’t like the result, it resolves quickly on its own. For people who do enjoy the effect, maintaining it means scheduling repeat appointments roughly every two to three months. Over time, some people find the muscle weakens slightly with repeated treatments, which can extend the interval between sessions.
Lip Flip vs. Surgical Lip Lift
A surgical lip lift is a permanent procedure that removes a small crescent of skin just beneath the nose, physically shortening the philtrum and pulling the upper lip upward. It produces a much more dramatic and lasting result than Botox, but it requires incisions, stitches, a healing period of one to two weeks, and carries risks of visible scarring. The cost is significantly higher, typically ranging from $2,000 to $5,000 or more.
Many practitioners suggest trying a Botox lip flip first as a low-commitment way to see whether you like the general effect of a more visible upper lip. If you find yourself returning for repeat Botox treatments and wishing the results were stronger or more permanent, that’s useful information for deciding whether a surgical lip lift is worth exploring. The Botox version won’t perfectly mimic surgical results, since it doesn’t change the skin length between your nose and lip, but it gives a directional preview of how a lifted upper lip looks on your face.
