A Botox lip flip is a quick, filler-free injection that relaxes the upper lip muscle so more of your natural lip shows, creating a fuller-looking smile without added volume. Results appear within 3-7 days and typically last 6-8 weeks per treatment.
A study by Fearington BS, et al., published in The Laryngoscope, found that increased gaze at the mouth in females is associated with significantly higher ratings of attractiveness by observers of the opposite sex. This is why there’s much interest in aesthetic procedures that enhance this facial feature.
Some people may opt for fillers to get fuller lips, but there’s also the Botox lip flip. This post will go over what this is, what kind of results you can get, and what else to expect.
What Is a Lip Flip Procedure?
A Botox lip flip is a cosmetic treatment that uses a small amount of Botox injected into the orbicularis oris muscle, which surrounds the mouth and controls lip movement. This makes the muscle relax and the upper lip roll slightly outward, and this creates the appearance of a fuller lip.
Do note that, unlike lip fillers, a lip flip doesn’t add volume to the lips. Instead, it changes the lip position so that more of the pink lip tissue is visible.
This treatment typically takes 5 minutes to do, and there’s no downtime or filler needed. It’s trending on social media too, so it’s a frequently searched cosmetic procedure.
How Does a Lip Flip Work?
During treatment, a provider injects Botox into 4-6 points along the upper lip border (Cupid’s bow). Over the 3-7 days, the muscle relaxes, which results in the upper lip curling upward and outward, showing more of the pink lip (vermillion).
The results are subtle, as a lip flip is designed to enhance the natural shape of the lip rather than dramatically increase its size.
Botox Lip Flip Before and After
Before a lip flip, many patients have thin or non-existent lips when smiling. But after treatment, they get a more visible upper lip and a natural Cupid’s bow, but with no stiffness. They’re able to smile, talk, and express themselves comfortably.
The results look best when smiling, so you’ll regain confidence in expressing yourself.
Who Is a Good Candidate for a Lip Flip?
A lip flip is good for people with a thin upper lip that disappears when smiling. In addition, those with a gummy smile can reduce the amount of gum shown when smiling with Botox.
It’s also ideal for those who want subtle lip enhancement without filler. On that note, if you’re considering filler but want to “try” fuller lips first, you may be a good candidate too.
Unfortunately, this procedure isn’t ideal for people who need a lot of volume. It’s also not ideal for musicians or wind instrument players since it affects your lip control temporarily.
How Many Units of Botox for a Lip Flip?
Typically, you’ll only need 4-6 units total, which is one of the smallest treatment amounts available. It’s placed precisely along the Cupid’s bow, and less is more here. Too many units can temporarily affect speech and eating.
Lip Flip vs Lip Filler: What’s the Difference?
Botox Lip Flip
A Botox lip flip changes your lip position, not volume. It takes 4-6 units, and there’s minimal swelling or bruising risk. It’s generally the lower-cost option too.
The results last 6-8 weeks. This is shorter than other Botox areas due to constant lip movement.
Lip Filler
Lip filler adds volume by using hyaluronic acid. There’s some swelling and bruising risk, but you get more dramatic results. The overall cost is usually higher than a lip flip.
The results last 6-12 months, depending on the product used and individual metabolism.
Can You Combine Both?
Yes, many patients combine a lip flip with lip filler. This combination works well together since the former helps improve lip shape and upper lip visibility, while the latter provides additional volume.
How Long Does a Lip Flip Last?
A Botox lip flip usually lasts 6-8 weeks, which is shorter than most Botox areas because your lips move constantly. Some patients see results up to 3 months.
What’s great is that it’s easy to maintain results with regular touch-ups. And it’s cost-effective, given the small number of units required to do so.
What to Expect During and After a Lip Flip
The lip flip procedure is quick and straightforward. Most appointments take only a few minutes, and there’s minimal discomfort, so no numbing is necessary.
Immediately after, your lips might look unchanged or slightly uneven as the muscles settle. This is both normal and temporary.
From days 3-7 on, results will begin to appear. Full results will typically come after 14 days.
As for aftercare, you should avoid the following for 24 hours:
- Pursing your lips
- Drinking through straws
- Applying pressure
After your Botox Lip Flip
Most patients find the lip flip comfortable enough that numbing cream isn’t necessary, and the treatment itself is over quickly.
Afterwards, avoid straws, excessive lip pursing, and any unnecessary pressure on the lips for the first 24 hours.
Results are subtle — you’ll notice a slightly fuller upper lip without anything dramatic or obvious — and if you want to address volume at the same time, a lip flip and filler can be combined in a single session. Some patients notice minor changes in lip movement in the first few weeks, but this is temporary and settles on its own.
How Much Does a Botox Lip Flip Cost?
In the US, a Botox lip flip costs around $100, with prices ranging from $80 to $200. It’s one of the most affordable Botox treatments.
However, you can get even cheaper Botox in Mexico, as prices can be up to 80% lower in this country.

Frequently Asked Questions
Does a Lip Flip Hurt?
Most patients describe it as mild, with only a quick pinch at each injection point along the upper lip border, since the treatment uses very few units. Numbing cream can be applied beforehand if you're sensitive to needles, though many patients skip it since the entire procedure takes only about 5 minutes. No anesthesia or sedation is needed.
Will a Lip Flip Affect My Speech?
A few patients notice minor, temporary changes in lip movement or pronunciation during the first few days while the Botox settles, especially with sounds that require a lot of lip control. This typically resolves within 1-2 weeks as you adjust to the new lip position. It's also one of the reasons musicians and wind instrument players are usually advised against this treatment, since it can affect the fine lip control their instrument requires.
Can I Eat and Drink Normally After a Lip Flip?
Yes, but avoid using straws, pursing your lips tightly, or applying unnecessary pressure to the treated area for the first 24 hours, since these specific actions can encourage the Botox to shift before it's fully settled. Outside of those few things, normal eating and drinking is fine right away.
Is a Lip Flip Noticeable?
It's noticeable but intentionally subtle. Since a lip flip changes lip position rather than adding volume, most people see a slightly fuller-looking, more visible upper lip, especially when smiling, without an obvious "done" look. If you want a more dramatic, voluminous change, lip filler is usually a better fit than a lip flip alone.
Can I Get a Lip Flip and Lip Filler at the Same Time?
Yes, many patients combine the two in the same appointment, since they address different things: the lip flip improves the position and visibility of the upper lip, while filler adds volume. Combining them is a common way to get a fuller, more defined look without relying on a large amount of filler alone.
Can I Fly Home the Same Day as My Lip Flip Appointment?
Yes. A lip flip has no real downtime and only takes a few minutes, so most international patients are comfortable flying home the same day or the next. Just avoid pursing your lips, drinking through straws, or putting pressure on the area for the first 24 hours, whether you're on a flight or at home.
