What is a lip flip: how it works and what to expect
By the Estetika Med Spa · · 4 min read
A lip flip is an injectable treatment that uses a small amount of Botox or Dysport injected into the muscle that runs along the upper lip. That muscle relaxes slightly, which causes the lip to roll outward and appear fuller without adding volume. The effect is subtle. It does not change the shape of your lips the way filler does, and the results typically last two to three months for most people.
If you have been scrolling through before-and-after photos and asking yourself what is a lip flip, you are probably noticing a specific look: the upper lip appears more defined and slightly fuller, but the face still looks like itself. That is the point. The lip flip is one of the most requested injectable treatments in aesthetic medicine right now, and the reason is simple: it does something filler cannot do on its own.
How the lip flip works
The treatment uses Botox or Dysport injected into the orbicularis oris, the circular muscle that controls your upper lip. A small amount placed just above the lip border relaxes that muscle enough to let the lip roll slightly outward. The lip does not get bigger. It does not get more tissue. It just stops being pulled inward, which for many people reveals lip that was already there.
The appointment itself takes under fifteen minutes. There is no incision and no recovery day.
What it looks like in practice
The result is a subtle outward curl of the upper lip. Patients often say their upper lip looks fuller when they smile, and that the pink part of the lip shows more at rest.
It is not a dramatic change. If someone is hoping for visibly larger lips, this treatment alone will likely not meet that expectation. But for someone whose upper lip disappears when they smile, or who wants more definition without added volume, the flip addresses exactly that.
At Estetika, the goal with any lip treatment is that you look like a rested version of yourself, not a different person.
How it compares to lip filler
These two treatments are often discussed together, and the comparison is worth being clear about.
| Lip flip | Lip filler | |
|---|---|---|
| How it works | Relaxes muscle to reveal lip | Adds volume with injectable gel |
| What changes | Curl and visibility of the lip | Size and shape of the lip |
| Typical duration | 2 to 3 months for most people | 6 to 12 months for most people |
| Downtime | Minimal | Mild swelling for a few days |
| Good for | Gummy smile, lip that disappears when smiling | Adding size, defining borders |
Some patients use both. Others find one is enough. The right answer depends on the lip anatomy and the goal, which is why the conversation with your injector matters before any decision is made.
The timeline from injection to result
You will not see the full effect immediately. The muscle takes a few days to respond to the neurotoxin. For most people, the lip flip is visible by day three to five and reaches its peak around day seven to ten.
The results then hold for roughly two to three months for most people before the muscle gradually resumes its normal activity. There is no sharp cutoff. The lip simply returns to its baseline over time.
If you want to maintain the look, a follow-up appointment is needed. This is standard with any neurotoxin treatment, including Botox and Dysport used elsewhere on the face.
What to expect the day of the appointment
The injector will assess your lip anatomy and ask about your goals. You do not need to arrive with a specific unit count in mind: that is a clinical decision made in the room based on your muscle and what you are trying to achieve.
The injections themselves take seconds per site. Some patients experience minor swelling or a small raised area at the injection point that resolves within hours. Bruising is possible, as it is with any injection near the lip.
You can return to most activities the same day. The American Society of Plastic Surgeons notes that patients are generally advised to avoid intense exercise and lying flat for a few hours after any neurotoxin injection, to allow the product to settle without displacement.

Who this treatment is not for
The lip flip does not add volume. A patient who wants visibly larger lips will likely be better served by filler, or a combination. The flip is a poor match for that goal.
It is also not appropriate for patients who are pregnant or breastfeeding. Patients with certain neuromuscular conditions should discuss their history with the injector before any neurotoxin treatment, as the U.S. Food and Drug Administration advises caution in those cases.
Patients whose main concern is vertical lip lines, often called smoker’s lines, may find the lip flip helpful but not complete on its own. Those lines are a separate target and may need their own approach.
And if someone has very active lip muscles used heavily for professional speech or performance, even a subtle relaxation can feel noticeable during the adjustment period. It resolves for most people, but it is worth raising before the appointment.
How to know if it fits your goals
The honest answer is that a photo or an article will only take the decision so far. Lip anatomy varies. What looks like a lip flip result on one person may require filler on another to achieve the same appearance, depending on how the muscle behaves and how much lip tissue is present.
The questions to bring to a consultation are simple: what is making me unhappy about my upper lip, and am I looking for more visibility or more volume? Those two questions point in different directions.
If you are ready to have that conversation with someone who can look at your actual lips, you can schedule a complimentary assessment at Estetika and get a recommendation based on your anatomy, not a general description of a treatment.
Frequently asked questions
How is a lip flip different from lip filler?
A lip flip relaxes the muscle above the upper lip so it rolls outward, creating the appearance of more lip. Filler adds actual volume by injecting a substance into the lip tissue itself. The flip is more subtle and lasts a shorter time. Some patients choose both, but they are different treatments with different results.
Does a lip flip hurt?
Most patients describe the injections as a brief pinch. The upper lip area has more nerve endings than some other injection sites, so some sensitivity is normal. For most people the discomfort passes within seconds and no significant downtime follows.
How long does a lip flip last?
For most people, the effect lasts approximately two to three months before the muscle gradually returns to its previous activity. Results vary depending on individual metabolism and muscle strength. A follow-up appointment is needed to maintain the look.
Can I get a lip flip if I have lip filler?
Yes, in many cases. A lip flip and lip filler are not mutually exclusive, and some patients use both at the same time to address different goals: the flip for the curl, filler for volume. Your injector will evaluate your current lip anatomy before recommending a combination or one alone.
Will a lip flip change how I speak or drink?
Some patients notice a brief adjustment period of a few days where sipping through a straw or pronouncing certain sounds feels slightly different. For most people this resolves quickly as the muscle adapts. It is worth mentioning to your injector before the appointment if you have a job that requires precise speech.
