A Botox lip flip has become one of the most requested subtle enhancements in aesthetic medicine, and it’s easy to see why. It’s quick, it’s reversible, and it can make a thin or flat upper lip look fuller without a single drop of filler. But it’s also one of the most misunderstood treatments out there, often confused with lip filler or assumed to add volume when it actually doesn’t.
This guide covers exactly what a Botox lip flip is, how the procedure works from start to finish, what it costs, how long it lasts, and the realistic risks and limitations you should know before booking one. Whether you’re trying to understand a gummy smile fix, deciding between a lip flip and filler, or just curious about the actual injection sites, this is the full picture.
A Botox lip flip is a non-surgical procedure where a small amount of botulinum toxin is injected into the upper lip’s orbicularis oris muscle, along with the corners of the mouth and the edges of the lips. This relaxes the muscle, causing the lip to “flip” outward and appear fuller, without adding any actual volume. Results typically last 2 to 5 months.

Key Takeaways
- A Botox lip flip relaxes the muscle above the upper lip so it rolls outward and appears fuller — it adds no volume.
- The procedure typically uses 2 to 4 units of Botox in the upper lip and about 2 units in the lower lip, though dosing varies by provider and anatomy.
- The entire appointment usually takes 10 to 20 minutes, with visible results appearing over about a week.
- Results generally last 2 to 5 months before the muscle returns to normal function.
- A Botox lip flip is often chosen by people who want a fuller-looking smile without the bruising, swelling, or cost of lip filler.
- Serious complications are rare, but signs like difficulty breathing, swallowing, or speaking after treatment require immediate medical attention.
What Is a Botox Lip Flip?
A Botox lip flip is a nonsurgical procedure that makes the lips appear fuller without increasing their actual volume. During the procedure, a healthcare provider injects botulinum toxin into the corners of the mouth (called the oral commissures) and the edges of the lips (the vermillion border). This relaxes the muscles surrounding the upper lip, causing it to “flip” upward slightly, a movement called eversion, so it appears larger than it does at rest.
This is fundamentally different from lip filler, which physically adds hyaluronic acid to increase lip volume. A lip flip repositions the lip you already have rather than adding anything to it. You can compare the two approaches directly in lip flip vs lip filler, and see the underlying mechanics explained further in how does a lip flip work.
What Types of Botox Can Be Used for a Lip Flip?
“Botox” is the most well-known botulinum toxin brand, and the name is often used generically to describe the entire treatment category, but several other FDA-approved options exist for this purpose:
- Botox (onabotulinumtoxinA) — the most commonly used and most studied option, detailed in botox-lip-flip-related comparisons like xeomin-vs-botox-lip-flip
- Dysport (abobotulinumtoxinA) — often chosen for a faster onset, covered in dysport-lip-flip
- Xeomin (incobotulinumtoxinA) — a purified, “naked” formulation without accessory proteins
- Jeuveau (prabotulinumtoxinA) — a newer option sometimes used off-label for this purpose
Your provider can help determine which product fits your muscle strength, budget, and past experience with neuromodulators.
Who Is a Good Candidate for a Botox Lip Flip?
Getting a lip flip is a personal decision, and candidates should generally be in good physical and mental health with realistic expectations about the outcome. People typically pursue a Botox lip flip for a few common reasons:
- A thin or flat upper lip. As people age, lips can lose volume, the philtrum (the groove between the upper lip and nose) can lengthen and flatten, and the distance between the corners of the mouth can increase.
- A preference to avoid filler. Some people simply don’t want the volume change, added cost, or increased bruising and swelling that can come with lip augmentation using dermal filler.
- A gummy smile. If your upper lip reveals more gum tissue than you’d like when you smile, a lip flip can help reduce that visibility. See Lip Flip Before and After Gummy Smile for real examples.
- Softening lines around the mouth. Because Botox relaxes muscle movement, it can also soften the appearance of fine lines that form during expression, which is covered in more depth in lip flip for smokers lines.
Candidates should not have an active oral infection, such as a canker sore or cold sore, at the time of treatment, and should discuss any known allergies, especially to cow’s milk protein, since some botulinum toxin formulations contain a milk-derived protein. A Botox lip flip is also not recommended during pregnancy, since there isn’t enough research confirming its safety in that context.
How Does a Botox Lip Flip Procedure Work?
Before Your Appointment
Your provider will typically ask about your goals and expectations, screen for any body image concerns, and review your medical history, allergies, and current medications. You’ll usually be advised to avoid alcohol, aspirin, and cigarettes for about a week beforehand, since alcohol and aspirin can thin the blood and cigarettes may increase bruising risk. Photos of your lips are commonly taken for your provider’s records.
During the Procedure
- A thin needle is used to inject small amounts of botulinum toxin into specific points of the upper lip, including the corners of the mouth and the edges of the lips.
- Numbing cream or a nerve block can be requested if you’re sensitive to needles, though the procedure typically isn’t painful enough to require it.
- Dosing is generally small — often around 2 to 4 units in the upper lip and about 2 units in the lower lip, though your provider will adjust based on your muscle strength and desired outcome. More detail on this is available in how many units of Botox for a lip flip and where to inject Botox for lip flip.
- The entire injection process usually takes only 10 to 20 minutes.
After the Procedure
You’ll typically be monitored for up to 15 minutes to check for any immediate reactions, such as dizziness, nausea, or swelling. Since Botox doesn’t cause drowsiness, you’re able to drive yourself home afterward. Mild swelling, sensitivity, or numbness in the lips is common and usually resolves within 24 hours. Full details on the healing process are covered in lip flip healing stages and lip flip recovery timeline.
How Long Does It Take to See Results?
Most people notice initial results within about a week, and full results are typically visible by the two-week mark. If you’re planning around a specific event, such as a wedding, it’s best to schedule your Botox lip flip at least two weeks ahead of time to allow the treatment to fully take effect. See how long does it take for a lip flip to work and lip flip results day by day for a fuller breakdown.
How Long Does a Botox Lip Flip Last?
A Botox lip flip typically lasts between 2 to 5 months, though the exact duration varies based on individual metabolism, muscle strength, and dosing. Because the lip area moves frequently throughout the day, results here may fade a bit faster than in less active muscle areas. To maintain the look, most people repeat the treatment every few months. You can see a broader timing breakdown in how long does a lip flip last.
Botox Lip Flip: Pros and Cons
| Pros | Cons |
| Non-surgical with minimal downtime | Results are temporary and require repeat treatment |
| Less bruising and swelling than filler | Cannot be reversed once injected — must wait for it to wear off |
| Lower cost per session than filler | Over-relaxation can cause drooling, speech, or drinking difficulty until it wears off |
| Quick appointment, usually 10–20 minutes | Doesn’t add volume, so it won’t achieve a dramatically fuller look |
| Can help with a gummy smile and expression lines | Rare risk of toxin spreading beyond the treatment area |
Botox Lip Flip Cost
Pricing for a Botox lip flip varies by provider, location, and the amount of product used, but it’s generally one of the more affordable injectable treatments available. Because it needs to be repeated every few months, most people budget for it as an ongoing cost rather than a one-time expense. Full pricing detail is available in lip flip cost and how much does a lip flip cost.
Does a Botox Lip Flip Hurt?
Most people describe a Botox lip flip as involving minimal discomfort, similar to a quick pinch with each injection. Since the treatment isn’t very invasive, numbing isn’t always used, though you can ask your provider for a topical numbing cream or nerve block if you’re especially sensitive to needles. See does a lip flip hurt for more detail on what to expect.
Aftercare: What to Do (and Avoid) After Your Botox Lip Flip
Proper aftercare helps your results settle evenly and reduces the small risk of the toxin migrating to nearby muscles. General guidance includes:
- Apply an ice pack for up to 10 minutes at a time to reduce swelling.
- Avoid lipstick, lip balm, or other lip products for at least three to four days.
- Avoid putting pressure on your lips, including touching, puckering, kissing, or drinking through a straw.
- Be gentle while brushing your teeth in the days following treatment.
- Avoid sleeping face-down for the first few nights.
- Skip alcohol for at least 24 hours, since it can worsen bruising.

Common Mistakes to Avoid
- Expecting added volume. A Botox lip flip repositions the lip you already have — it does not plump or increase lip size the way filler does.
- Skipping the two-week planning window before an event. Results take about a week to appear and up to two weeks to fully settle.
- Overdoing the treatment area. Injecting too much or too close to the mouth’s natural movement zones can cause drooling, speech difficulty, or trouble drinking until the Botox wears off.
- Ignoring allergy history. Always disclose any milk protein allergy, since some botulinum toxin formulations contain a milk-derived protein.
- Choosing an inexperienced injector. Precision matters enormously in this small, delicate treatment area.
Warnings and Risks
A Botox lip flip is generally considered safe when performed by an experienced healthcare provider, and complications are uncommon. That said, real risks exist and are worth understanding:
- The upper lip muscle may relax more than intended, potentially causing temporary drooling, difficulty drinking, or trouble speaking clearly until the Botox wears off.
- Once injected, the effect cannot be reversed — if you’re unhappy with the outcome, you’ll need to wait for it to fade naturally.
- Mild side effects like headache, fever, chills, or tenderness at the injection site can occur.
- Though extremely rare, botulism has been reported as a potential complication of botulinum toxin injections.
Seek medical attention immediately if you experience difficulty breathing, difficulty swallowing or talking, impaired vision, or muscle weakness in other parts of your face or body after treatment, even if these symptoms appear weeks after your procedure, since they can indicate the toxin has spread beyond the treatment area.

Frequently Asked Questions
What is the difference between a Botox lip flip and lip fillers? A Botox lip flip relaxes the upper lip muscle so it appears fuller without adding volume, while lip fillers use hyaluronic acid injected into the lip to physically increase its size. Lip flips generally look more subtle and natural than fillers.
How many units of Botox are used in a lip flip? Dosing varies by provider and anatomy, but a common range is around 2 to 4 units in the upper lip and about 2 units in the lower lip.
How long does a Botox lip flip last? Most results last between 2 and 5 months before the effects of the botulinum toxin wear off and the muscle returns to normal function.
Can a Botox lip flip go wrong? Complications are uncommon when performed by an experienced provider, but over-relaxation of the muscle can occasionally cause temporary drooling, speech difficulty, or trouble drinking until the treatment wears off.
Is a Botox lip flip reversible? No. Once injected, the effect cannot be undone. If you’re unhappy with the result, you’ll need to wait until the Botox naturally wears off, typically within a few months.
Can I get a Botox lip flip while pregnant? This isn’t recommended, since there hasn’t been enough research to confirm its safety during pregnancy.
Does a Botox lip flip help with a gummy smile? Yes, this is one of the more common reasons people seek this treatment, since relaxing the upper lip muscle can reduce how much gum tissue shows when smiling.
How soon will I see results from a Botox lip flip? Most people notice initial changes within about a week, with full results typically visible within two weeks.
Is a Botox lip flip painful? Most people describe it as involving minimal discomfort, similar to a quick pinch. Numbing cream can be requested if you’re sensitive to needles.
Can I combine a Botox lip flip with lip filler? Yes, many patients combine both for a fuller shape along with added volume. This is worth discussing directly with your provider, and you can read more in lip flip with filler.
Who shouldn’t get a Botox lip flip? People with an active oral infection, a known allergy to botulinum toxin ingredients, or who are pregnant are generally advised against this treatment. A consultation can clarify whether it’s appropriate for your specific situation.
Will a Botox lip flip make my smile look unnatural? When dosed and placed correctly by an experienced provider, a Botox lip flip typically looks natural. Overdosing or improper placement is the most common cause of an unnatural or uneven result.
Summary: Botox Lip Flip
A Botox lip flip is a quick, non-surgical treatment that relaxes the upper lip muscle to create a fuller, more visible lip without adding any actual volume. It’s a popular alternative for people who want subtle enhancement without the bruising, swelling, or cost associated with lip filler, and it’s also commonly used to soften a gummy smile.
Results generally last between 2 and 5 months, the procedure itself takes only 10 to 20 minutes, and side effects are typically mild and temporary when performed by an experienced provider. As with any injectable treatment, a consultation is the best way to confirm you’re a good candidate and to set realistic expectations for your specific lips and goals.
