A Botox lip flip relaxes the upper lip muscle so your top lip rolls outward, for a fuller-looking lip with no filler, no swelling, and no long commitment.
What a lip flip is, and what it is not
A lip flip uses a few units of Botox (typically 3 to 6) placed into the orbicularis oris muscle along the upper lip. The muscle relaxes just enough to let more of the pink upper lip roll outward and become visible. No filler, no added volume, just the lip you already have showing more of itself. It is a popular entry-level lip enhancement and a sensible step for anyone who wants a subtle change before committing to lip filler. It will not add volume, change a thin lip to a full one, or fix asymmetry caused by underlying anatomy, and it does not last as long as filler.
How the lip flip works
The injector places small amounts of botulinum toxin (Botox, Dysport, or Nuceiva, all approved in Canada) superficially into the muscle at the vermilion border, usually at two to four points such as the Cupid’s bow peaks and the lateral mid-lip. This gently weakens the muscle’s pull, letting the upper lip border rotate outward and show a little more pink lip at rest, on the order of one to two millimetres. Onset begins around day 3, peaks at day 10 to 14, and lasts roughly 6 to 10 weeks before muscle function returns to baseline. It is shorter-lived than frown-line Botox because the muscles around the mouth are constantly active during speech, eating, and expression.
Lip flip for a gummy smile
One of the most useful applications is softening a gummy smile. When the upper lip lifts high and exposes a strip of gum, relaxing the muscle that raises it can lower the lip line slightly so less gum shows when you smile. The dose and exact placement differ from a standard flip, and we assess whether a lip flip alone is enough or whether it is better combined with a small amount of filler. We will tell you honestly what your anatomy will and will not allow.
Lip flip versus lip filler, what to pick
A lip flip is best if you already have decent lip volume but feel your top lip disappears when you smile. Lip filler is the better choice if you want genuine added volume, more definition, or to correct asymmetry. The two combine well: many people pair a lip flip with a small amount of filler for a soft, natural result, with the flip extending the visual border and the filler doing the volume work.
| Factor | Lip flip (Botox) | Lip filler (HA) |
|---|---|---|
| Mechanism | Muscle relaxation, border rotation | Physical volume addition |
| Duration | 6 to 10 weeks | 9 to 12 months |
| Reversible | Wears off naturally | Yes, with hyaluronidase |
| Adds volume | No | Yes |
| Best for | Vermilion show, gummy smile | Volume, definition, hydration |
How many units does a lip flip take?
Most lip flips use 3 to 6 units of neurotoxin, with around 4 units being a common starting dose. We deliberately keep the dose conservative. Older, heavier dosing (8 or more units) tends to over-weaken the muscle and cause the temporary straw and whistling problem, so a measured dose preserves normal function while still giving the roll you want. Your exact dose is set at consultation based on your muscle strength and your goal.
What to expect at the appointment
The appointment takes about 15 minutes. We apply topical numbing, mark the injection points along the upper lip border, and inject with a fine 32G needle, which most people find very tolerable. You can return to your day right away. The effect appears around day 3 to 5, peaks at day 10 to 14, and lasts 6 to 10 weeks.
What to avoid for the first 24 hours
No drinking through a straw, no whistling, no forceful kissing, and no strenuous exercise. The Botox needs time to settle into the muscle before you stress it.
Who should not get a lip flip
We do not treat during pregnancy or breastfeeding, or anyone with a neuromuscular disorder. We are also cautious with people who play wind instruments or sing professionally, because the muscle relaxation can affect lip seal for a few weeks. We screen for all of this at consultation and walk you through alternatives if a lip flip is not right for you.

The Botox lip flip is one of the most over-promised and under-explained micro-treatments in Toronto aesthetic medicine. Marketed on social media as a free filler alternative, it has led a lot of people to expect a dramatic pout from a tiny dose of Botox. The reality is more nuanced, more useful, and more limited than the marketing suggests. Done correctly, the lip flip is a precision tool: a small dose of neurotoxin placed in the orbicularis oris to relax the muscle just enough to let the upper lip border rotate outward by a millimetre or two. Done incorrectly, it produces a temporarily floppy upper lip that interferes with drinking from a straw, kissing, and pronouncing the letters p, b, and m. This page exists to set realistic expectations before you book.
The mechanism, step by step
The injector identifies the vermilion border at two to four points along the upper lip, most commonly at the Cupid’s bow peaks and the lateral mid-lip, and deposits a fraction of a unit at each point using a fine needle. The injection is intramuscular but superficial, and the toxin diffuses a short distance from each deposit, which is why precise placement matters. Onset begins at day 3, peaks at day 10 to 14, and lasts 6 to 10 weeks before muscle function returns to baseline. The shorter duration compared with frown-line Botox reflects how constantly the muscles around the mouth work during speech, eating, and expression.
What it does not do
The lip flip does not add volume. It does not turn a thin lip into a full one. It cannot fix asymmetry caused by underlying anatomy or scarring, and it does not last as long as hyaluronic acid filler (weeks versus months). It is not a substitute for filler if you genuinely want larger lips; it is a complement that lets a small amount of filler look more proportionate. It can soften dynamic lines around the mouth slightly by relaxing the underlying muscle, but it does not erase etched-in smoker lines on its own.
Red flags, when to walk out of the consult
Standards across Toronto clinics vary, and a few warning signs reliably predict a poor outcome. If you spot any of the following during your consult, leave and book elsewhere.
- No medical history form. If the clinic does not collect a written intake covering autoimmune disease, blood thinners, recent vaccinations, and prior procedures, they are skipping a basic safety step.
- Pricing posted per syringe with no unit count. Reputable clinics quote per regulated unit of neurotoxin or per millilitre of hyaluronic acid filler.
- The injector cannot show the lot number. Every vial of neurotoxin and filler carries a lot and expiry. You can ask to see it, and a vague answer is a red flag.
- Pressure to add a second treatment the same day. Upselling another procedure before the first is consented and planned is a concern.
- No emergency hyaluronidase on site. Any clinic doing filler must stock hyaluronidase to reverse a vascular occlusion quickly. Ask, and watch the answer.
- No physician medical director named. In Ontario, nurse injectors work under a delegated medical directive from a physician, whose name should appear on the clinic’s website.
Paying for treatment in Ontario
Aesthetic treatment in Ontario is rarely covered by OHIP, because most procedures are classed as elective and cosmetic. There are still a few legitimate ways to reduce the cost, and we walk every client through them.
Health spending accounts (HSA)
If you are self-employed, incorporated, or work for an employer offering a flexible HSA, you can often submit receipts where the treatment has a documented medical indication (for example, neurotoxin for hyperhidrosis or migraine). The receipt must be issued by a regulated health professional and itemized. We provide HSA-compatible receipts on request.
OHIP coverage (rare but real)
OHIP covers neurotoxin only for specific documented medical conditions such as severe primary axillary hyperhidrosis, chronic migraine (with a neurologist referral and failed first-line therapy), cervical dystonia, and blepharospasm. It does not cover any cosmetic indication. We can refer you to a covering specialist if you suspect a billable diagnosis.
Medical expense tax credit
The federal Medical Expense Tax Credit may apply to procedures performed for a medical (not cosmetic) purpose by an authorized practitioner. Keep itemized receipts and the practitioner’s licence number, and speak to your accountant about your situation.
Affirm financing
For larger treatment plans, Affirm financing is available so you can split the cost into monthly payments. Checking your rate does not affect your treatment plan.
Frequently asked questions
How much does a lip flip cost in Ontario?
A lip flip is priced by the number of Botox units used, and at Bar Beauty Medical Botox is $10 per unit, so a typical lip flip is a small number of units. The exact total depends on your dose and whether you combine it with filler. We publish current pricing on our price list, and your consultation is complimentary.
How much should I pay for a lip flip?
Because it is dosed in units, a lip flip is one of the more affordable injectable treatments. Be cautious of clinics that quote a flat price with no unit count, since that makes it hard to compare value. We quote per unit and confirm the dose with you before treating. See our price list for current rates.
Is it worth doing a lip flip?
For the right person, yes. If your upper lip rolls under or disappears when you smile and you do not want added volume, a lip flip is a low-commitment way to show a little more lip. If you want genuine fullness, filler is the better value because it lasts far longer. Many people find the combination of the two the most worthwhile.
Where can I get a lip flip in Toronto?
At our clinic at 46 Fort York Blvd in CityPlace, central to downtown Toronto and easy to reach from across the GTA. Book a complimentary consultation by calling or texting 416-923-1200.
How long does a lip flip last?
Six to ten weeks on average. This is shorter than full-face Botox because the muscles around the mouth are in constant use, which metabolizes the neurotoxin faster.
Is the lip flip painful?
Mild. We apply topical numbing for about 15 minutes and use a fine 32G needle. Most people describe it as a brief pinch at each point, and the injection itself takes under two minutes.
How many units are in a lip flip?
Usually 3 to 6 units, often around 4. We keep the dose conservative to preserve normal lip function while still giving the outward roll.
What should I not do after a lip flip?
For the first 24 hours, avoid straws, whistling, forceful kissing, and strenuous exercise, so the Botox can settle into the muscle.
Can I have a lip flip and lip filler together?
Yes, and many people find the combination the most natural-looking. We usually do filler first, then add the flip about two weeks later once any filler swelling has resolved. See our price list for combination pricing.
Will I have trouble drinking from a straw or whistling?
With a conservative dose, no. The 3 to 6 unit approach preserves enough muscle function for normal activities. Much higher doses used at some clinics can cause temporary straw difficulty for a few weeks.
Can a lip flip cause a droopy lip?
Improper injection can cause uneven weakness, which is why injector experience matters. We use a fixed injection pattern with documented unit counts, and if any asymmetry shows up we can adjust at the two-week follow-up.
How soon will I see results?
Onset starts around day 3, with the full effect at day 10 to 14. We book the review at the two-week mark.
Is the lip flip safe during pregnancy or breastfeeding?
No. Botulinum toxin is not used during pregnancy or breastfeeding. We screen for this at consultation and reschedule accordingly.
How does the lip flip compare to a Russian lip filler technique?
They serve different goals. The Russian technique is a specific filler pattern that builds a more vertical lip shape with volume. The lip flip is a Botox treatment that subtly rolls the upper lip outward without volume. The two can be combined.
Can the lip flip fix smoker lines?
Partially. It relaxes the muscle and softens dynamic lines, but established etched lines usually need microneedling, resurfacing, or a small amount of fine filler for full correction.
What is the touch-up policy?
Our neurotoxin treatments include a complimentary two-week review, with a touch-up at no additional charge as long as no promotion or discount was applied to your original treatment.

The Downsides of Lip Flips: Side Effects and Trade-offs
No cosmetic treatment is perfect, so here are the honest trade-offs. The most common side effects are minor and temporary: slight bruising, swelling, or tenderness at the injection sites, usually resolving within a few days. Some people notice mild asymmetry in the first week as the Botox takes effect, which typically evens out as the result develops.
There are functional effects worth knowing about. Because we relax the muscle around your mouth, some people temporarily find it odd to drink through a straw for the first week or two, notice slight changes in how certain words sound, or experience minor drooling, especially at night, because the lips seal a little less tightly. These changes are almost always temporary and settle as you adjust. This is why we start conservative: we can always add more at a touch-up, but we cannot remove it once injected.
A lip flip can also change your smile, and for many people that is the goal. If you have a gummy smile, the flip reduces how much gum shows. If you love your current smile and just want a slightly fuller upper lip at rest, we are precise with placement and dosing to enhance without altering your smile. Finally, results are temporary. At 8 to 12 weeks, the lip flip is one of the shorter-lasting Botox treatments, so it needs regular maintenance. For some people that flexibility is a plus, for others it is a reason to choose longer-lasting filler instead.
Combining a Lip Flip With Other Treatments
Many of our clients combine a lip flip with other treatments for a more complete result. The most common pairing is a lip flip plus a small amount of dermal filler. The flip handles upper-lip definition and gum show, while strategic filler adds volume where needed, such as the body of the lips or the cupid’s bow. This combination often looks more natural than a large amount of filler alone.
If you have vertical lip lines, the flip reduces the muscle movement that creates them, and you may also benefit from a resurfacing treatment such as microneedling or a chemical peel to improve skin texture. For more advanced lip aging, pairing a flip with skinboosters can hydrate and improve skin quality while the flip enhances shape. The key is a comprehensive plan, so at your consultation we look at the whole lip area and build a strategy that works together, sometimes spacing treatments over a few months and sometimes combining them in one visit.
